Abstract:

Abstract Various hypotheses have been put forward to explain the etymology of Old It. (zucchero) caffettino (Jaffa < Yāfā, cafis < qafīz, Caffa = Feodosia, caffa < qafaṣ, Haifa < Ḥayfā, Kafá < ?, coffa < quffa(h)). All these proposals, however, are unsustainable for reasons of cultural-historical and/or semantic, phonetic and morphological incompatibilities. In reality the etymon is the Arabic nisba adjective of the name of the Egyptian city of Qifṭ (qiftī), which in Medieval times was highly renowned for its sugar production. The Arabic equivalent of zucchero caffettino is as-sukkar al-qiftī. The phonomorphological adaptation of caffettino is absolutely regular (anaptyctical e, gemination f > ff, initial ca- < qi-, final –ī > -ino); the original type qiftī is still reflected by the ancient Italian and Romance variants chafethi, cafeti and cafati.

Abstract:

The tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite, single-stranded begomovirus that was first identified in India in 1995 affecting solanaceous crops. A different strain, named ToLCNDV-ES, was introduced in Spain in 2012 and causes severe symptoms in zucchini crops. Virus transmission experiments with the whitefly Bemisia tabaci, were used to compare the transmission parameters in zucchini and tomato plants. The minimum acquisition access period and inoculation access period of ToLCNDV-ES transmission was similar in zucchini and tomato. However, the transmission efficiency was significantly higher in zucchini (96%) compared to tomato (2%). The maximum retention of the virus in the vector was 16 days. B. tabaci feeding on, or recently emerged from infected zucchini plants, accumulated more virus than those from infected tomato, as determined by real-time PCR. A total of 20% of B. tabaci that were recently emerged from infected zucchini, and none from infected tomato, were able to transmit the virus to virus-free zucchini. The results may explain the different incidences of ToLCNDV-ES in zucchini and tomato crops in Spain. But they are also relevant for ToLCNDV-ES management of crops and the role of the trade and transport of infected plant material, when small-sized immature stages of B. tabaci could be a source of infection.

Abstract:

The Gray Zucchini cultivar of summer squash is widely consumed as a fresh market vegetable in Northwest Mexico but is highly suceptible to viral diseases. Gray Zucchini type lines were developed by interspecific hybridization using a local landrace of Cucurbita moschata, which has shown high levels of viral resistance, as male parent and suceptible C. pepo cv. classic as female. The lines were obtained after 4 backcrossing and 3-5 selfing generations. In 1993 average commercial yield of first generation hybrids between lines was 28,155 kg/ha followed by line × Gray Zucchini hybrids, lines, commercial hybrids (Classic. Corsair, Onyx, Raven), and open pollinated cultivars (Gray Zucchini, Black Zucchini) with 26,594, 21,062, 18,862 and 10,172 kg/ha respectively. Yield was inversely related to symptoms of viral infection.

Abstract:

In order to improve zucchini production, the combined effect of charcoal amendment and seeding depth was tested at the botanical garden of the Peleforo Gon Coulibaly University in Korhogo. To this end, six (6 kg) of activated charcoal were buried in the elementary plots one month before sowing in order to assess its effect on soil fertility. The experimental design was that of completely randomized two-factor blocks which are charcoal amendment and depth. Sowing was carried out one month after the application of charcoal due to three seeds per hill at different depths. Namely 0 inch, 1.5 inch and 3 inch. These same depths were repeated on control plots in order to compare their effect on the agronomic performance of zucchini. The results obtained show that after a campaign of use of biochar, the chemical parameters of the soil (pH, CEC, K+, exchangeable Ca2+ and exchangeable Mg2+) experienced significant increases. The porosity has also been reduced. Zucchini fruit yields increased by 100-250% with charcoal compared to the control. Therefore, the use of charcoal can be popularized as a sustainable alternative to conventional fertilization to improve the yield of zucchini on sandy loam soils. Zucchini fruit yields increased by 100-250% with charcoal compared to the control.

"Physiological and Transcriptomic Analyses Revealed That Humic Acids Improve Low-Temperature Stress Tolerance in Zucchini (Cucurbita pepo L.) Seedlings."

Abstract:

Zucchini (Cucurbita pepo L.) is one of the main vegetable crops grown under protected cultivation in northern China. Low-temperature (LT) stress severely inhibits the growth of zucchini seedlings, resulting in reductions in yield and quality. Here, using three kinds of different humic acids, including coal-based humic acid (CHA), fulvic acid (FA), and biochemical humic acid (BHA), we investigated the effects of humic acids against LT stress (5°C) in zucchini seedlings. Treatment with all three kinds of humic acids improves LT stress tolerance by decreasing oxidative damage through increases in antioxidative enzyme activities and the contents of soluble sugar and proline in zucchini seedlings, especially after BHA application. Comparative transcriptomic analysis revealed that a total of 17 differentially expressed genes (DEGs) were commonly induced in the leaves of FA-, CHA-, and BHA-treated zucchini seedlings under LT stress, including calmodulin, ethylene-responsive transcription factors (TFs), peroxidases, and 10 TFs, including two NAC and seven WRKY genes. Altogether, these results indicated that supplementation with humic acids reprograms plant metabolism and modulates the expression of genes involved in ROS scavenging, phytohormone metabolism, or signaling pathways, finally improving LT stress tolerance in zucchini seedlings.

Abstract:

The effect of N application level on uptake and partitioning of nutrients by zucchini squash (Cucurbita pepo L.) cv. Blackjack, head lettuce (Lactuca sativa L.) cv. Monte110 and potato (Solanum tuberosum L.) cv. Sebago was investigated in sand culture experiments with a stable nutrient supply. Plants were grown during 14 (zucchini squash), 8 (lettuce) and 12 weeks (potato). Five nitrate N levels ranging from 2-36 mol m-3 for lettuce and 2-43 mol m-3 for zucchini squash and potato were applied in a complete nutrient solution. Gamma x quadratic response surface models fitted actual nutrient uptake data (R2> 0 . 9 5 ) . From these models, predicted nutrient uptake, partitioning of nutrients between plant parts and nutrient uptake rates were derived. Nitrogen had a pronounced effect on nutrient uptake of all species. The maximum predicted whole plant (excluding roots) uptake of N and K (parenthesis) was calculated (mol m-3 N) for zucchini squash (19.3, 17.7), lettuce (16.5, 12.1) and potato (12.7, 11.2) respectively. An N deficiency (2 mol m-3)did not result in remobilization of nutrients from vegetative to reproductive growth for zucchini squash and potato. Remobilization of N and K from outer leaves to head occurred for lettuce over the last week of the growth period at all N levels. An N deficiency increased partitioning of N and K by 36 and 54% respectively to reproductive growth for zucchini squash compared with adequate N for fresh yield (14 mol m-3), whereas an N deficiency had a negligible effect on partitioning to reproductive growth for potato. Partitioning, as measured by the ratio of nutrients in fruit, head or tuber to whole plant increased over the growth period, and at final harvest, partitioning was lowest for Ca (0.22-0.24 zucchini squash, 0.21-0.32 lettuce and 0.03-0.09 potato) and highest for K (0.39-0.60 zucchini squash, 0.59-0.68 lettuce and 0.63-0.86 potato). Potato tubers and lettuce head, in contrast to zucchini squash fruit, were dominant sinks for N, K and P.

Abstract:

Abstract It is known that vegetables are sources of vitamins, biologically active substances, antioxidants and other vital micronutrients. In particular, pumpkin vegetable crops (zucchini, squash) contain all the necessary mineral salts, vitamins, trace elements, pectin substances, ascorbic acid and not too many sugars. Varieties of vegetable crops are characterized by a diverse biochemical composition and are suitable to various degrees for obtaining processed products for therapeutic, preventive and functional purposes. The article considers the assortment of zucchini and squash by yield and the most important indicators of the biochemical composition of the fruit: the content of dry substances, sugars, vitamin C; the accumulation of nitrates in the fruit. High water content of zucchini and squash fruits (94-96%), low sugar content ( 1.5-3.5%) were found. Squash has a higher yield (25-90 t / ha), compared to zucchini (4-11 t/ha). Nevertheless, zucchini contain 3-4 times more vitamin C in the fruit and accumulate 3-4 times less nitrates than squash, having almost 10 times more of vitamin value. At the same time, squash is 2-3 times less than zucchini, accumulating nitrates. Of the 7 studied varieties of zucchini, the hybrid Belogor F1 and the variety Tsukesha were distinguished, which have high yield, high fruit quality and vitamin value. Of the 15 studied varieties of squash, the varieties Perlinka, Pyatachok and Tabolinsky were identified, which have high yields, high fruit qualities and vitamin value, and weakly accumulate nitrates.

Abstract:

Zucchini (Cucurbita pepo L.) has a great economic and productive potential in the semi-arid region of Brazil, due to the wide acceptance by consumers and quick financial return. The nitrate (NO3-) assimilation process in C3 plants such as zucchini is related to photorespiration, and Si accumulated near the stomata reduces the transpiration rate, making the photosynthesis cycle more efficient. The objective of this study was to evaluate the interaction between nitrogen and silicon fertilization ongrowth, chlorophyll index, and chlorophyll a fluorescence of zucchini plants. The treatments were distributed in a split-plot scheme in a randomized block design with three replicates. The plot was arranged by silicon levels (0 and 6 g/plant) and the subplots constituted by five nitrogen levels (30, 60, 90, 120 and 150 kg ha-1). Leaf, stem and total dry masses, chlorophylla, chlorophyll b, total chlorophyll, chlorophyll a/b ratio and chlorophyll a fluorescence were evaluated. The highest dry matter productions in zucchini were obtained in treatments without Si. Si and N application together positively influences the chlorophyll a/b ratio of zucchini plants. The interaction between Si and N positively influences the maximum fluorescence, variable fluorescence and quantum yield of photosystemII of zucchini plants.

Abstract:

Zucchini yellow mosaic virus (ZYMV, Potyvirus) is a very damaging cucurbit virus worldwide. Interspecific crosses with resistant Cucurbita moschata have led to the release of “resistant” zucchini squash (C. pepo) F1 hybrids. However, although the resistance is almost complete in C. moschata, the commercial C. pepo hybrids are only tolerant. ZYMV evolution toward increased aggressiveness on tolerant hybrids was observed in the field and was obtained experimentally. Sequence comparisons and recombination experiments revealed that a point mutation in the P3 protein of ZYMV was enough to induce tolerance breaking. Competition experiments were performed between quasi-isogenic wild-type, and aggressive variants of ZYMV distinguished by monoclonal antibodies. The aggressive mutants were more fit than wild-type strains in mixed infections of tolerant zucchini, but they presented a drastic fitness loss in mixed infections of susceptible zucchini or melon. Thus, the ability to induce severe symptoms in tolerant zucchini is related to a genetic load in susceptible zucchini, but also on other susceptible hosts. This represents the first quantitative study of the fitness cost associated with tolerance breaking for a plant virus. Thus, although easily broken, the tolerance might prove durable in some conditions if the aggressive variants are counterselected in susceptible crops.

Abstract:

A 2-year field experiment was carried out in a Mediterranean environment to study the effects of vetch (Vicia sativa L.) residue management strategies incorporating green manure (GM) using a roller-crimper (RC) and different organic fertilizers (municipal solid waste compost, anaerobic digestate, and a commercial organic fertilizer) on organic zucchini (Cucurbita pepo L.) yield and quality. Zucchini yield was influenced positively by the vetch residue management strategy, although the response was significantly different between years. The vetch cover crop increased marketable zucchini yield in the first year by 46.6% compared with the fallow (FA) treatment, indicating that this fertility-building crop could reduce off-farm nitrogen (N) fertilizer input for subsequent crops. Averaging over 2 years of the experiment, marketable zucchini yield increased by 15.2% and 38% with the RC mulch and GM plow-down, respectively, compared with the FA treatment, although differences were significant in the first year only. The application of organic fertilizers in vetch management plots increased marketable zucchini yield by 21.8% in the first year compared with the unfertilized control. This result is particularly relevant, because organic fertilizers were applied at ≈50% of the normal application rate for zucchini after taking into account biological N fixation attributable to the vetch. The concentrations of soil mineral N at harvest were 19, 27, and 28 mg·kg−1 for the RC, FA, and GM treatments, respectively. These mineral N concentrations indicated that a portion of applied organic fertilizer N, and N attributable to vetch (GM and RC), remained in the soil at harvest, suggesting the potential for leaching, which should be taken into account in the overall fertilization program. These research findings suggest that effective vetch cover crop management and the application of organic fertilizers can improve yield and quality of organically managed zucchini.

Abstract:

Large populations of sweetpotato whiteflies (Bemisia tabaci) have become more regular occurrences during the fall months in parts of the southeastern United States. Large populations of sweetpotato whiteflies have resulted in a significant increase in the incidence of sweetpotato whitefly-transmitted viruses, particularly the cucurbit leaf crumple virus (CuLCrV), which has the potential to cause complete yield loss of fall-planted yellow squash and zucchini (Cucurbita pepo). This study evaluated commercial cultivars of yellow squash and zucchini for resistance against CuLCrV and estimated the yield and fruit quality under environmental conditions during the fall growing season in the southeastern United States. A factorial experimental design was conducted with nine yellow squash and 11 zucchini cultivars during Fall 2017, Fall 2018, and Fall 2019 in Tifton, GA. In situ weather stations monitored the weather conditions during growing seasons, and yellow pest monitor cards monitored the sweetpotato whitefly populations in 2018 and 2019. During all growing seasons, yellow squash and zucchini plants were rated weekly for the severity of CuLCrV. Harvests were conducted 12 times during each season, and fruit were graded as fancy, medium, and culls. Rainfall distribution directly affected the sweetpotato whitefly populations during the production year. In 2018, frequent rainfall events created field conditions that reduced the sweetpotato whitefly populations compared with those during 2017 and 2019. The severity of CuLCrV negatively impacted both the yield and quality of fruit of yellow squash and zucchini, and no resistant commercial cultivars of yellow squash or zucchini were identified. Nonetheless, the yellow squash cultivars Lioness, Gold Prize, and Grand Prize, and the zucchini cultivars SV6009YG and SV0914YG had the highest yields when subjected to the highest sweetpotato whitefly populations during the study.

Abstract:

Conservation agriculture is a concept for resource-saving agricultural crop production system that serves to achieve acceptable profits and sustaining production while conserving the environment. The popularity of zucchini also known as baby marrow in the Kingdom of Eswatini has increased in recent years specifically for its economic value in the foreign market. This study was carried out at Malkerns Research Station, Malkerns in the Middleveld of the Kingdom of Eswatini to assess the effectiveness of different tillage methods and cultivars on growth, yield and quality of zucchini. The tillage methods used were zero, basin and mulch tillage. Furrow tillage was used as a control. The results showed that tillage methods had significant (P<0.05) differences in growth and yield of zucchini. Minimum tillage plants exhibited lowest number of leaves (9.5), vine length (36.4 cm), leaf area index (2.5) and number of flowers (6), number of fruits (1.3) and marketable yield/plant (4.6 ton/ha). Non-significant (P>0.05) differences were obtained from plants grown under basin, mulch and furrow tillage. The highest vine length (69.6cm), leaf number (17.0), LAI (3.6), and marketable yield (15.7 ton/ha) were obtained in zucchini plants grown under basin tillage system. However, there were no significant (P>0.05) differences in accumulation in leaves of zucchini plants of mineral content. In terms of the cultivars there were no significant (P>0.05) differences in vegetative growth. Star 8023 showed superiority in terms of number of fruits and marketable yield. It was observed that minimum tillage was less suitable in zucchini production as compared to other tillage systems. For higher production in zucchini, basin, furrow and mulch may be used. The best cultivar to use is star 8023.

Abstract:

There is dearth of information pertaining to hydroponics production of zucchini in the Kingdom of Eswatini. The objective of this study was to determine the effects of hydroponics systems on growth, yield and nutritional content of zucchini. The research was conducted in three greenhouses of the Horticulture Department, Faculty of Agriculture, Luyengo Campus at the University of Eswatini between July and October 2018. The experiment was laid out in a split-plot design replicated four times. Three hydroponics systems were used as the main plots, i.e. elevated tray, ground lay bed and Nutrient Film Technique (NFT) systems. The sub-plots were allocated to the three varieties, i.e., Amanda, Hygreen and Terminator. The zucchini grown in elevated tray hydroponics system had the highest yield in all the varieties compared to the other hydroponics systems. The results showed that there were significant differences in the growth, yield and nutritional content of zucchini cultivars grown in the different hydroponics systems. The tallest plants (26.1cm) were obtained in cultivar Terminator grown in the elevated tray system and the highest number of leaves (15) was obtained in cultivar Terminator grown in the elevated tray system. Cultivar Terminator grown in the elevated tray system had the highest total yield (15.8 tons/ha) while Hygreen plants produced in the NFT system recorded the lowest total yield (1.04 tons/ha). There were no significant differences in the iron content of zucchini among the cultivars grown in the different hydroponics systems. The results of this study revealed that different zucchini cultivars responded differently when grown in the different hydroponics systems. Therefore based on the results of this study it is recommended that Terminator zucchini cultivar can be produced in the elevated tray hydroponics system.

Abstract:

Yellow and zucchini squash (Cucurbita pepo L.) cultivars/elite lines (cultigens) were evaluated over two seasons (fall 1995 and spring 1996) in North Carolina. Different cultigens were tested over the 2-year period for both yellow and zucchini squash, although some cultigens were tested both years. Cultigen recommendations are based on yield, quality, disease resistance, and season grown. Yellow squash cultigens that yielded well include: Destiny III, Freedom III, Multipik, TW 941141, Liberator III (fall 1995); and HMX 4716, Superpik, PSX 391, Monet, Dixie, Picasso, and XPH 1780 (spring 1996). Superior-yielding zucchini squash cultigens were: TW 940981, Tigress, TW 940982, ZS 19, Elite, and Noblesse (fall 1995); and Leonardo, Hurricane, Elite, HMX 4715, Noblesse, and Tigress (spring 1996). Virus ratings for fall 1995 indicated that some transgenic plants with virus resistance withstood virus infection better than those without resistance. These were Freedom III, Destiny III, Freedom II, Liberator III, Prelude II, and TW 941121 (yellow), and Tigress, TW 940982, TW 940981, TW 940866 (zucchini). Virus-infected plants were assayed and viruses were determined to be zucchini yellow mosaic, watermelon mosaic II, and papaya ringspot.

Abstract:

Italian zucchini is a very important crop due to its short cycle, high productivity and great market acceptance. The objective of this study was to evaluate the emergence and growth of Italian zucchini plants in substrates enriched with sewage sludge. The study was conducted in a greenhouse using Italian zucchini seeds purchased at a local commerce. The substrates were composed of dystrophic Yellow Red Latosol; sand and sewage sludge in the proportions of 0; 40; 80; 120 and 240 t ha-1, in a randomized block design. Each experimental plot was composed of twenty replicates. The following variables were analyzed: emergence, emergence velocity index, first leaf length, stem length, number of leaves, fresh and dry aerial plant part, volume and root dry mass. It was verified that the post-seminal growth of Italian zucchini is viable in maximum concentration of up to 398.56 t ha-1 of sewage sludge.

Abstract:

Zucchini (Cucurbita pepo) is worldwide affected by Pseudomonas syringae, inducing vein clearing, stunting, and necroses during plantlet development. A collection of 58 P. syringae strains isolated from diseased zucchini plantlets was characterized by multilocus sequence analysis (MLSA). A subset of 23 strains responsible for vein clearing of zucchini (VCZ) was evaluated for pathogenicity on zucchini, and their genomes were sequenced. The host range of six VCZ strains was evaluated on 11 cucurbit species. Most VCZ strains belong to clades 2a and 2b-a within phylogroup 2 of P. syringae species complex and are closely related to other strains previously isolated from cucurbits. Genome analyses revealed diversity among VCZ strains within each clade. One main cluster, once referred to by the invalid pathovar name (peponis), gathers VCZ strains presenting a narrow host range including zucchini and squashes. Other VCZ strains present a large host range including zucchini, squashes, cucumber, melons, and in some cases watermelon. The VCZ strain pathogenic features are strongly associated with type III effector repertoires. The presence of avrRpt2 and absence of hopZ5 are associated with a narrow host range, whereas the presence of hopZ5 and absence of avrRpt2 are most generally associated with a large host range. To better detect the different clusters identified with whole genome sequence and pathogenicity analyses, we used a specific-k-mers approach to refine the MLSA scheme. Using this novel MLSA scheme to type P. syringae isolates from diseased cucurbits would give insight into distribution of worldwide strains and origin of epidemics.

Abstract:

Food-waste is produced throughout all the food supply chain, with a large part already achieved at farm level. In fact, fruits and vegetables, which do not satisfy aesthetic demands, cannot be marketed, but their recovery could favour their valorisation for the obtainment of highly qualified goods. In this context, faulty zucchini fruits (cultivar ‘Lungo Fiorentino’), intended for disposal, were rescued as effective, inexpensive and bio-sustainable source for cosmeceutical purposes. Zucchini fruits underwent extraction and fractionation to obtain ZLF-O and ZLF-A extracts, which were chemically characterized by UHPLC-HRMS. ZLF-A extract, rich in flavonols and flavones, scavenged massively DPPH• and ABTS•+, and was not cytotoxic at doses up to 200 μ g/mL. Thus, ZLF-A was incorporated into a base cream formula. Zucchini-based emulsion was deeply screened for its antiradical properties and cytotoxicity towards human keratinocytes and fibroblasts. ZLF-A-enriched cream, whose chemical stability was assessed over time and mimicking different storage conditions, was further tested on reconstructed epidermis disks (EpiskinTM). The recovery of valuable chemical substances from zucchini agro-food waste, complying with the principles of valorisation and sustainable development, can represent a new market force for local farmers. Data acquired were eager to convey a suitable reuse of nutraceuticals rich zucchini waste.

The effects of high temperatures on melon cvs. Miranda and Poli, watermelon cv. Crimson Tide and zucchini cv. Asma leaves. The leaves obtained from plants were subjected to 35, 40, 45, 50, 55 and 60°C temperatures with gradual increments every 30-minutes. Samples, obtained at each treatment, were analyzed for ascorbic acid content, NADP(H) oxidase, catalase, gluthatione reductase, peroxidases activities and isoperoxidase patterns. The ascorbic acid content slightly increased parallel to temperature increment in zucchini but did not change in watermelon and in both melon cultivars. Melon cv. Poli exhibited comparatively less oxidative damage than cv. Miranda with a lower NAD(P)H oxidase activity. Heat stress induced NAD(P)H activity in watermelon and zucchini comparing to control plants. Results revealed that antioxidative enzyme activities were increased generally up to 50°C then decreased gradually in melon cultivars. Besides cv. Poli generally had higher enzyme activities than cv. Miranda. The activity of catalaes become prominent in watermelon while the activity of ascorbate peroxidase become prominent in zucchini. Acidic isoperoxidase bands with different relative mobility values were found in all species. Besides, basic isoperoxidase band could not be determined in both melon cultivars and watermelon while a basic isoperoxidase band was found in zucchini.

Abstract:

AbstractIntegrating cover crops into vegetable cropping systems can provide a wide range of ecological services, of which weed management is a key component. Cover crop effects on weed control, however, are dependent on termination methods and weed species present in specific cropping seasons. A 2-year weed management experiment with two cultivars of organic zucchini (Cucurbita pepo L.) in central Italy was carried out to compare the effect of a barley (Hordeum distichum L.) cover crop terminated with a modified roller-crimper (RC) to incorporated barley as green manure (GM) and a tilled control left fallow (FA) in the off-season. The effects of cover-crop management on crop competitiveness, yields and weed populations were evaluated by direct measurement, visual estimation and competition index methods. Results showed a significant reduction in weed biomass (>80%) and weed abundance with the RC compared to the GM and FA treatments. Moreover, the RC barley mulch maintained weed control in zucchini plots even under high weed pressure, as determined by the agronomic tolerance to competition (ATC) value of 67% in the RC treatment compared to 40 and 34% in the FA and GM treatments, respectively, averaged over both years of the experiment. The competitive balance (Cb), which quantified the ability of the zucchini crop to compete with weed populations, was also greater (+0.37) in the RC treatment compared to FA (−0.87) and GM (−0.69) treatments over the same period. Zucchini crop biomass was greatest in the RC treatment in 2011. Zucchini fruit yields varied from an average over both years of 1.4 Mg ha−1 in the RC treatment to 0.7 Mg ha−1 in the GM treatment, but yields in the FA treatment, 1.2 Mg ha−1, did not differ from the RC treatment. No differences in yield between ‘Dietary’ and ‘Every’ zucchini, or any significant interactions between cultivar and cover management related to fruit biomass, were observed. Our findings suggested the viability of the modified RC in creating a barley cover-crop mulch to effectively manage weeds and enhance yields in transplanted zucchini.

Abstract:

Zucchini squash (Cucurbita pepo) is a systemic host for most strains of the cucumovirus Cucumber mosaic virus (CMV), although the long-distance movement of the M strain of CMV (M-CMV) is inhibited in some cultivars. However, co-infection of zucchini plants with M-CMV and the potyvirus Zucchini yellow mosaic virus strain A (ZYMV-A) allowed M-CMV to move systemically, as demonstrated by tissue-print analysis. These doubly infected plants exhibited severe synergism in pathology. Infection of zucchini squash by M-CMV and an attenuated strain of ZYMV (ZYMV-AG) showed a milder synergy in pathology, in which ZYMV-AG also facilitated the long-distance movement of M-CMV similar to that promoted by ZYMV-A. Variation in the extent of synergy in pathology by the two strains of ZYMV did not correlate with differences in levels of accumulation of either virus. Thus, the extent of synergy in pathology is at least in part independent of the resistance-neutralizing function of the potyvirus.

Abstract:

Market sales of ready-to-use fresh fruit and vegetables have grown quickly in the recent years as a result of changes in consumer attitudes. The goal of this work was to evaluate the effect of two kinds of cuts on the physiological, physical, physical-chemical, chemical and biochemical traits of fresh-cut 'Menina Brasileira' zucchini stored in rigid polypropylene packages, with lids of the same material containing sliced and grated zucchini and stored at 5º C, for 15 days. The variables respiratory rate, pH, L* value, soluble pectin, PME and PG activity, was interactively affected by the cut type and storage time factors. The variables mass loss, phenylalanine ammonia-lyase activity and total pectin variable were only significantly affected by storage time factor. It can be concluded that sliced 'Menina Brasileira' zucchini shows a higher titratable acidity and soluble solids and a lower respiratory rate, pectin soluble and phenylalanine ammonia-lyase activity when compared with grated zucchini, contributing to the preservation of quality attributes.

Abstract:

Relevance. Squashes are a promising culture, and the recent work of breeders allow us to uncover large reserves to improve their nutritional and dietary qualities. The dietary value of zucchini is due to the easy digestibility of all carbohydrates, which allows them to be used in the production of canned foods. Canned snacks and candied fruits are produced from zucchini. The most important quality of the varieties we study is their cylindrical shape, allowing mechanization of the cleaning operation.Methods. Therefore, the purpose of this work was to use zucchini of different degrees of ripeness for the preparation of candied fruit with the least loss of products.Results. As a result of research conducted at the All-Russian Research Institute of Irrigated Vegetable and Melon-Growing in the Astrakhan Region, it was found that zucchini fruits of different degrees of maturity can be used to make candied fruits, but the highest yield was obtained from mature squash, and amounted to 654 kg from the Sosnovsky variety , in the Orange variety 696 kg from one ton of prepared raw material, while in the Orange variety of candied fruits it was obtained 42-64 kg more than in the Sosnovsky variety, depending on the degree of ripening STI. The tasting committee rated candied fruits obtained from the fruit of the zucchini of the Orange variety higher by 0.3-0.5 points than from the Sosnovsky variety. In terms of chemical composition, candied fruits prepared from the raw material of ripe zucchini fruits exceeded 1.2-1.5 times - from unripe fruits. Ready candied fruits can be used as an independent form, as well as for the preparation of other types of products in the food industry.

Abstract:

Zucchini (Cucurbita pepo L.) is a horticultural crop of great socioeconomic importance in Brazil and in the world. However, inappropriate fertilization management, such as over-fertilization of soils, may become a limiting factor for its development. Thus, the aim of this study was to evaluate the morpho-physiological behavior of zucchini submitted to nitrogen (N) doses applied via soil and foliar application of silicon (Si). The treatments were distributed in split-plot scheme in a randomized block design, with three replications. The plot was formed by silicon levels (0.0 and 6.0 g plant-1) and the subplots constituted by five nitrogen levels (30, 60, 90, 120 and 150 kg ha-1), adding up to 30 experimental units. Gas exchanges and growth parameters were assessed at 35 days after planting. The data were submitted to analysis of variance by the F test and in the cases of significance was performed a polynomial regression analysis for the nitrogen factor and Tukey test for the silicon factor. The supply of Si positively enhances the effects of N on growth characteristics and gas exchanges of zucchini. The simultaneous application of Si and N does not influence the leaf area of zucchini. The N dose of 93.9 kg ha-1 provides greater assimilation of CO2 in zucchini plants under the conditions in which the experiment was performed.

Abstract:

Fusarium crown and foot rot of zucchini squash (Cucurbita pepo L.) caused by Fusarium solani f. sp. cucurbitae is one of the major diseases affecting zucchini squash production in Almería, Spain. Experiments were conducted to determine the pathogen’s ability to survive in infested bags of perlite and to test several control methods under greenhouse conditions. The pathogen survived in the bags for at least 20 months with enough inoculum at that time to produce disease symptoms in zucchini plants, although disease severity was significantly reduced after 14 months. A total of 14 zucchini cultivars were inoculated with F. solani f. sp. cucurbitae, and all were highly susceptible to the disease. Eight fungicides and two microbial products, Trichoderma harzianum and Rhizophagus irregularis, were tested to determine their efficacy for the control of this disease. Prochloraz, carbendazim, and thiophanate-methyl, which are not labeled for use in zucchini in Spain, were highly effective for the control of the disease, while the other products were ineffective. Two soil solarization and biosolarization experiments were conducted in a greenhouse for 45-day periods during the summer. Inocula in the soil samples decreased by more than 99%, indicating the efficacy of completely closing the greenhouse windows, solarization, and biosolarization in reducing inoculum. Fungicide applications, crop rotation for at least two years, and soil solarization or biosolarization are promising control methods for this disease.

Abstract:

The work is aimed at the selection of linear samples of zucchini (Cucurbita pepo L. var. Giromontia Duch.) with increased complex resistance to abiotic factors of cultivation – zucchini yellow mosaic virus (ZYMV), powdery mildew, bacteriosis and other viral pathogens. Selection studies on choosing virus-resistant zucchini lines from the United Kingdom, Italy, the United States and Spain have identified a number of important correlations levels of resistance to ZYMV and to harmful microorganisms and viruses, belonging to other genera. The assessment of the resistance of the selected zucchini lines to the complex of studied diseases was performed on a 9-point scale of the classifier of the Council for Mutual Economic Assistance (CMEA). In total, during 2017–2019, 20 lines of zucchini were studied in the field. According to the complex resistance to all pathogens (zucchini yellow mosaic virus, green speckled mosaic, white mosaic and cucumber mosaic, bacteriosis and fusarium wilt), four lines have been identified – LZ 17-11, RVL-19, LZ 17-45 and LZ 17-49, which were resistant at the level of points 7 and 9 on the scale of CMEA. The possibility of selecting potentially resistant linear zucchini genotypes for ZYMV based on correlations with the manifestation of other diseases that occurred in the field has been confirmed. The highest level of correlation 0.59<rp<1.0) is observed when comparing the degree of powdery mildew development and symptoms of ZYMV (17 statistically confirmed values of the pairwise correlation coefficient or 80.95 %). A similar indicator for the pair “bacteriosis/ZYMV” is 14 statistically confirmed values of the pairwise correlation coefficient or 66.67 % (–1.0<rp<0.99), and for the pair “field viruses of other origin/ZYMV” – 11 values, which is 52.38 % (–1.0<rp<0.93). Zucchini samples were identified, in which statistically significant correlations were observed for all pairs of comparative traits. Among them, the variety-standard Chaklun and 4 more lines – LZ 17-1, LZ 17-8, LZ 17-50 and LZ 17-44 (–1.0<rp<0.92). The analysis of correlations shows a complex genetic organization of signs of resistance in zucchini lines to the studied pathogens and a high dependence of the manifestation of these signs on the response of the genotype of the line. One of the proofs of this experimental fact is that in all comparative pairs of indicators of the degree of development of certain diseases there are linear genotypes with both positive and negative values of Pearson correlation coefficients (rp). The high level of statistically significant correlations revealed gives grounds for wide use of correlation analysis in selection work for choosing lines potentially resistant to the complex of the most common diseases in vegetable agrocenoses

Abstract:

Zucchini (Cucurbita pepo L.), extensively cultivated in temperate areas, belongs to the Cucurbitaceae family and it is a species with great economic value. One major threat related to zucchini cultivation is the damage imposed by the cotton/melon aphid Aphis gossypii Glover (Homoptera: Aphididae). We performed RNA-sequencing on cultivar “San Pasquale” leaves, uninfested and infested by A. gossypii, that were collected at three time points (24, 48, and 96 h post infestation). Then, we combined all high-quality reads for de novo assembly of the transcriptome. This resource was primarily established to be used as a reference for gene expression studies in order to investigate the transcriptome reprogramming of zucchini plants following aphid infestation. In addition, raw reads will be valuable for new experiments based on the latest bioinformatic tools and analytical approaches. The assembled transcripts will serve as an important reference for sequence-based studies and for primer design. Both datasets can be used to support/improve the prediction of protein-coding genes in the zucchini genome, which has been recently released into the public domain.

Abstract:

Zucchini fruit are highly sensitive to low temperatures leading to significant peel depressions, increasing weight loss and making them impossible to be commercialized. In this study the effect on the reduction of chilling injury (CI) assaying different postharvest treatments to cv. Cronos was evaluated. We have compared the application of substances such as 1-methylcyclopropene (1-MCP) with the application of a natural origin compound as melatonin (MT), both with demonstrated activity against CI in different vegetal products. The effects of MT (1 mM) by dipping treatment of 1 h and 1-MCP (2400 ppb) have been evaluated on zucchini fruit during 15 days of storage at 4 °C plus 2 days at 20 °C. Treatments applied independently improved some fruit quality parameters in comparison with control fruit but were not able to manage CI even though they mitigated the impact on several parameters. However, when these two separated strategies were combined, zucchini cold tolerance increased with a synergic trend. This synergic effect affected in general all parameters but specially CI, being also the only lot in which zucchini fruit were most effectively preserved. This is the first evidence in which a clear positive effect on zucchini chilling tolerance has been obtained combining these two different strategies. In this sense, the combined effect of 1-MCP and MT could be a suitable tool to reach high quality standards and increasing shelf life under suboptimal temperatures.

Abstract:

Zukini (Cucurbita pepo L.) belongs to the pumpkin tribe (Cucurbitaceae) including annual plants that live in the highlands. The need for zucchini in Indonesia is increasing along with the growing number of restaurants serving Japanese and Korean dishes. Information about the cultivation of zucchini in Indonesia is still limited, so that zucchini is rarely found among farmers. The purpose of the experiment was to get the right concentration of Bioboost fertilizer in order to give maximum zucchini yields. The experiment was conducted from February to April 2022 in Cihanjuang Rahayu Village, Parongpong, West Bandung Regency, West Java Province with an altitude of 1.243 m above sea level. The experiment menthod used complete randomized block design (CRBD) of five treatment and five replications. Each treatment consisted of 5 plants. so the total number was 125 plants. Treat the experiment A : 0 cc Bioboost/liter of water, B : 20 cc Bioboost/liter of water, C : 40 cc Bioboost/liter of water, D : 60 cc Bioboost/liter of water, E : 80 cc Bioboost/liter of water. The results showed that the concentration of Bioboost fertilizer was effective on the number of leaves, age of flower initiation, number of fruit/plant, fruit length/plant, fruit diameter/plant and fruit weight/plant. The application of Bioboost with a concentration of 60 cc/liter of water had the best effect on the growth and yield of the varieties Jacky Z-6 zucchini plant

Abstract:

Zucchini plants with symptoms including twisted petioles, necrotic leaves, crown rot, and internal fruit rot were found in Bundaberg, Australia, at a commercial field for the first time during late autumn 2016, resulting in direct yield losses of 70 to 80%. Three Pseudomonas syringae strains isolated from symptomatic leaf (KL004-k1), crown (77-4C), and fruit (KFR003-1) were characterized and their pathogenicity evaluated on pumpkin, rockmelon, squash, and zucchini. Biochemical assays showed typical results for P. syringae. The three isolates differed, however, in that two produced fluorescent pigment (KFR003-1 and 77-4C) whereas the third, KL004-k1, was nonfluorescent. Multilocus sequence analysis classified the isolates to phylogroup 2b. The single-nucleotide polymorphism analysis of core genome from the Australian and closely related international isolates of P. syringae showed two separate clusters. The Australian isolates were clustered based on fluorescent phenotype. Pathogenicity tests demonstrated that all three isolates moved systemically within the inoculated plants and induced necrotic leaf symptoms in zucchini plants. Their identities were confirmed with specific PCR assays for P. syringae and phylogroup 2. Pathogenicity experiments also showed that the Eva variety of zucchini was more susceptible than the Rosa variety for all three isolates. Isolate KL004-k1 was more virulent than 77-4C on pumpkin, rockmelon, squash, and zucchini. This study expands the knowledge of P. syringae isolates that infect cucurbits and provides useful information for growers about the relative susceptibility of a range of cucurbit species.

Abstract:

Cucumbers (Cucumis sativus L.) and zucchini squash (Cucurbita pepo L.) were pressure-infiltrated (82.7 kPa for 3 min) with methyl jasmonate (MJ) in aqueous suspension and then stored at a chilling temperature of 5C. Control fruit were infiltrated with distilled water and handled in a similar manner. Treatment with MJ delayed the onset and reduced the severity of chilling injury symptoms in both cucumbers and zucchini squash. Analysis of polyamines in zucchini squash showed that putrescine increased with time in storage at 5C, while spermidine and spermine decreased during the same period. MJ treatment did not have an appreciable effect on putrescine, but the treated fruit maintained higher levels of spermidine and spermine than the control fruit throughout storage at 5C.

Abstract:

The effect of boron (B) and molybdenum (Mo) foliar fertilization on `Spineless Beauty' zucchini (Cucurbita sp.) fruit yield was studied in Nigua, San Cristobal, Dominican Republic. Field trials were conducted in a loamy clay soil containing 0.3 parts per million (ppm) of B and no detectable amounts of Mo (detection limit 0.1 ppm). Zucchini was direct-seeded at a distance of 1 m between rows and 0.5 m within rows. Fertilization (except B and Mo applications) and other production practices were implemented as recommended. A randomized complete-block design with a factorial arrangement (0, 1, 2, and 3 kg B and 0, 0.1, and 0.2 kg Mo/ha) with four replications was utilized. Experimental units consisted of five plants. Fruits were harvested every other day during 20 days, starting 40 days after crop emergence. Yield data was submitted to analysis of variance. Significant B and Mo rate interactions were found. Maximum zucchini yields were achieved when the combination of 1.5 kg B and 0.1 kg Mo/ha was applied. Combinations containing 3 kg B/ha were toxic to zucchini, reducing yields in nearly 20% as compared to untreated plants.

Abstract:

Field trials were conducted in Nigua, San Cristobal, Dominican Republic, to determine the yield response of `Spineless Beauty' zucchini (Cucurbita sp.) to nitrogen (N), phosphorus (P), and potassium (K) soil applications in a loamy clay soil containing 4.3% organic matter, 3 parts per million (ppm) of P, and 155 ppm of K. Zucchini was direct-seeded at a distance of 1 m between rows and 0.5 m within rows. Except for N, P, and K fertilization, the crop was grown according to recommended practices. A factorial design (4 × 4 × 4) with four replications was utilized. Rates of N, P, and K were 50, 100, 150, and 200 kg·ha–1, applied as a side dressing 7 days after zucchini emergence. Zucchini fruit harvest started 40 days after crop emergence and every other day thereafter during 20 days. Analysis of variance was performed on the resulting data. Results indicate that there were significant interactions of N, P, and K fertilizer rates on `Spineless Beauty' fruit yield; therefore, nutrient combinations were considered as individual treatments. Significantly superior (lsd 5%) fruit yield was obtained with 150, 150, and 50 kg·ha–1 N, P, and K, respectively.

Abstract:

Tomato leaf curl New Delhi virus (ToLCNDV) (family Geminiviridae, genus Begomovirus) has recently been introduced in western Mediterranean countries. Isolates in Spain constitute a new strain, denominated ToLCNDV-ES, that is causing losses in commercial zucchini and melon crops; however, it is also, although less often, detected in commercial tomato crops. We developed a tissue-print hybridization test to detect the two genomic components of the virus and a TaqMan quantitative polymerase chain reaction (qPCR) test to estimate the number of genome copies in plants. qPCR was approximately 104 to 106 times more sensitive than tissue-print hybridization to detect viral genomic DNA-A and DNA-B, respectively. It also detected the virus in more experimentally and naturally ToLCNDV-ES-infected zucchini squash and tomato plants. ToLCNDV-ES DNA-A titers were significantly lower in tomato than in zucchini plants, often falling below the detection limits in the hybridization test. In addition, the DNA-B accumulation was impaired in tomato when compared with zucchini. According to the data obtained in this study, the differences in viral titers of both plant species contribute to explain the dissimilarities in symptom expression, capability of detection, and transmission of the virus.
