TRAINING AND MENTORING OF ORGANIC VEGETABLE CULTIVATION IN BAROS VILLAGE, SERANG REGENCY. The increasing number of people and public awareness about the health of the growing demand for organic vegetables is also increasing. This is one of the business opportunities in the field of organic agriculture, especially organic vegetable cultivation. The economic analysis of organic vegetable cultivation shows that organic vegetable cultivation is profitable, so it can be used as an effort to increase people's income. Organic vegetables are vegetables that are processed by environmentally friendly process, using organic materials from agricultural and livestock waste, without using synthetic chemical fertilizers, and synthetic pesticides. Baros Village, Baros District, Serang District is an agricultural area suitable for organic vegetable cultivation, the availability of land for agriculture, good irrigation, organic fertilizer source widely available, and close to the capital of Banten province. Organic vegetable cultivation uses organic ingredients from agricultural and livestock waste that are around the site. Selection of vegetable seeds is done by selecting seeds that are superior and needed by the community. Soil processing is done by plowing the soil, followed by basic fertilization. Organic vegetable preservation is done with advanced organic fertilization, weeding, irrigation, and vegetable pesticide administration. The harvesting process is done by selecting good organic vegetables, washing, and packing vegetables. The most important aspect of community service programs is the potential for sustainability. The sustainability of the Organic Vegetable Cultivation program is able to support the economy and public health.

The aim of the study was to elaborate a universal calibration for the near infrared (NIR) spectrophotometer to determine the moisture of various kinds of vegetable seeds. The research was conducted on the seeds of 5 types of vegetables – carrot, parsley, lettuce, radish and beetroot. For the spectra correlation with moisture values, the method of partial least squares regression (PLS) was used. The resulting qualitative indicators of a calibration model (R = 0.9968, Q = 0.8904) confirmed an excellent fit of the obtained calibration to the experimental data. As a result of the study, the possibilities of creating a calibration model for NIR spectrophotometer for non-destructive moisture analysis of various kinds of vegetable seeds was confirmed.<br /><br />

ABSTRACT Objective: Evaluate the effect of planting herb or vegetable seeds and seedlings on the household availability of fruits and vegetables through an intervention study combining various actions (educational practices, home visits, and distribution of seeds and seedlings) for the promotion of fruit and vegetable consumption in multiple settings. Methods: Data from 70 families were analyzed. Using the stratified sampling technique, the participant families were selected from a stratum within a population of 1,743 families living in three low-income communities in the city of Rio de Janeiro, Brazil. Three post-intervention groups were formed and compared: families that did not receive the seeds and seedlings during the intervention; families that received but did not plant the seeds and seedlings; families that received and planted the seeds and seedlings. Results: Among the families that did not grow their own fruits and vegetables before the intervention, those that received and planted the seeds and seedlings achieved an increase in household availability of fruits and vegetables (Δ=+5.8 percentage points) up to three times higher (p<0.05) than that achieved by the families who did not receive the seeds and seedlings (Δ=+1.8 5 percentage points) and those that received but did not plant them (Δ=+2.3 percentage points). As for the families that grew their own fruits and vegetables before the intervention, the comparison between those that did not receive the seeds and seedlings, those that received and planted them, and those that received but did not plant them showed no differences in the household availability of fruits and vegetables. Conclusion: The planting of the seeds and seedlings that they received by the families that did not grow their own fruits and vegetables before the intervention contributed to a significant increase in the household availability of fruits and vegetables.

Questions of quality of the sowed seeds in agriculture have paramount value. Use of highquality uniform seeds is the key to successful production of crop production. Vegetable seeds, in particular, leaf vegetables, are most vulnerable in this plan in view of their shallow amount, the long period of fructing time and some other factors. The modern tool methods of evaluation test allow to glance in internal structure of seeds and to scoop more information. The most suitable for these purposes is us the developed method of microfocal X-ray of vegetable seeds. In this work seeds of different types of green and spicy and flavoring vegetable crops are analysed: melissa, marjoram, asparagus, spinach and garden cress. The analysis was carried out both by a method of r of seeds, and by a standard technique. The most typical defects and shortcomings of internal structure of seeds influencing their economic and biological indicators are identified. Comparison of methods is carried out. It is shown that X-ray analysis of quality of seeds, in particular, viability, by visualization of images efficient and rather precise. The small error of a method is compensated with its bigger informational content: that is, the analysis is carried out not by the principle of viable and not viable seeds, there is their division as on viability (full, low quality), and on defects and shortcomings (outstanding, ugly, the defective, injured, etc.). At the same time seeds as a result of the analysis aren't utilized and remain for further work. The method differs in speed and ease of execution. The prospects of development of a method are specified. It is the integrated automatic analysis of quality of seeds. The algorithm of automatic computer X-ray analysis of quality of vegetable seeds is so far developed, the first version of the program is approved.

Sesame seeds are a functional food ingredient with vasoprotective, antioxidant, prebiotic, chondro- and osteoprotective characteristics. In this study, sesame seeds were used to enrich a cheese product. The dose, method and technological production stage of the cheese product in which to add sesame seeds were determined, in addition to the effect of sesame seeds on the product’s quantitative indicators. The nutritional value of sesame seeds, their total amino acid and fatty acid compositions and microbiological parameters were evaluated, depending on the method of the filler temperature treatment. The appropriate heat treatment method was holding the functional component in milk at 73 ±2 °C for 25 min, followed by cooling to 30 ±2 °C. Adding the filler into the cheese mass before moulding the cheese head was determined as the appropriate technological step to introduce the previously prepared sesame seeds. The cheese product was found to have the best sensory characteristics at the 3% sesame seed dose compared with the doses of 1% and 5%. The cheese product enriched with sesame seeds can be recommended as a functional product for systematic consumption without restrictions for all groups in a healthy population.

In protected ground, vegetables are exposed to various pests and pathogens of viral, bacterial or fungal diseases. Growing vegetables indoors requires the elimination of all chemical treatments and control over pathogens and pests. In this regard, the application of sensitive methods based on molecular markers in the diagnostics of pathogens is highly relevant. In this work, polymerase chain reaction was used to identify the most common diseases of tomato (Xanthomonas euvesicatoria), cucumber (Ascochyta cucumis) and potato (Clavibacter michiganensis subsp. Sepedonicus) plants. It was established that early diagnosis of vegetable diseases using polymerase chain reaction allows rapid detection of trace amounts of pathogenic microorganisms thus facilitating selection of effective fungicidal preparations. The creation of biological protection for vegetable crops is relevant considering their nutritional importance. New biological methods for protecting vegetables in greenhouses were tested. Thus, the fungicidal effect of the authors’ patented preparation developed for pre-sowing treatment of vegetable seeds in protected ground on the pathogens of tomato black bacterial spot (Xanthomonas euvesicatoria) and cucumber stem hypertrophy (Ascochyta cucumis) was confirmed. Another preparation patented as a means of pre-sowing treatment of pea seeds demonstrated fungicidal action against the development of Phytophthora infectants on potato plants. It was observed that these preparations are effective at concentrations of 10-4 % for soaking seeds and double treatment of plants during the flowering period.

Selecting the proper seeder setup to meter a given seed lot effectively can be very difficult for a vegetable grower, especially if the seed lot is not graded for size uniformity. A belt-type seeder should effectively singulate the seeds if the seeds are spherical and uniform because the holes are specifically sized. Seeds that are not graded for size uniformity may not be singulated effectively by a belt-type seeder. A vacuum-type seeder should uniformly meter a wider range of seed sizes better than a belt-type seeder since the holes in the seed plate must only be smaller than the smallest seeds in the lot. Seed lots (graded and ungraded) of two turnip (Brassica rapa L. rapifera group) cultivars were metered with a belt seeder using belts with holes 6/64 inch (2.4 mm) or 7/64 inch (2.8 mm) in diameter or with a vacuum seeder. Neither the belt nor vacuum seeder satisfactorily singulated any of the seed lots. With the larger (7/64 inch) belt holes, there were excessive incidences of multiple seeds per drop. With the smaller (6/64 inch) belt holes, multiple drops and missed seed were excessive. The vacuum seeder also resulted in excessive misses and multiples.

Selecting the proper seeder setup to effectively meter a given seed lot can be very difficult for a vegetable grower, especially if the seed lot is not graded for size uniformity. A belt-type seeder should be able to effectively singulate the seeds if the seeds are spherical and uniform because the holes are specifically sized. Seeds that are not graded for size uniformity may not be singulated effectively by a belt-type seeder. A vacuum-type seeder should be able to uniformly meter a wider range of seed sizes better than a belt-type seeder since the holes in the seed plate must only be smaller than the smallest seeds in the lot. Seed lots (graded and ungraded) of two cultivars of turnip (Brassica rape L.

Neither the belt nor vacuum seeder resulted in satisfactory singulation with any of the seed lots. With the larger [7/64 inch (2.8 mm)] belt holes, there were excessive incidences of multiple seeds per drop. With the smaller [6/64 inch (2.4 mm)] belt holes, multiple drops and missed seed were both excessive. The vacuum seeder also resulted in excessive misses and multiples.

Thesis (PhD (Chemistry and Polymer Science))--University of Stellenbosch, 2011.ENGLISH ABSTRACT: Due to the commercial, nutritional and health value of vegetable oils, seeds and beans, the analysis of their components is of much interest. In this dissertation oil-containing food products, specifically vegetable oils, seeds and beans, were investigated. Selected minor components of three locally produced vegetable oils, namely apricot kernel, avocado pear and macadamia nut oils were investigated using 31P NMR spectroscopy. These minor components, including 1,2 diacylglycerols, 1,3 diacylglycerols and free fatty acids, were identified in the 31P NMR spectra of each of the three vegetable oils for the first time. Two approaches were used for the quantification of the minor components present in the spectra. A calibration curve approach used known concentrations of standard minor components to establish calibration curves while a direct correlation approach calculated the unknown concentration of minor components in the vegetable oils using a known amount of standard compound within the analysis solution. These approaches aided in determining the concentration of minor components during storage studies in which vegetable oils were stored in five different ways: exposed to light, in a cupboard, in a cupboard wrapped in tin foil, at -8 °C and at 5 °C. It was found that determining the best storage condition for each oil was difficult since individual minor components were affected differently by the various storage conditions. However, in general the best storage conditions appeared to be 5 °C and -8 °C. The oil, protein and carbohydrate contents of sesame, sunflower, poppy, and pumpkin seeds, and soy, mung, black and kidney beans were analysed by thermogravimetric analysis and 13C NMR solid state NMR spectroscopy. It was shown that the first derivative of TGA data for seeds and beans can give valuable information about the carbohydrate, moisture, protein and fat content. This has not been previously demonstrated. For the seeds, the integration of a region between 270–480 ºC was equal to the sum of the oil and protein content and compared well to quantitative results obtained by other conventional methods. For beans the integration of a region between 180-590 ºC, gave a value which represented the sum of the oil, protein and carbohydrate content. 13C solid state NMR spectroscopy, including SPE-MAS, CP-MAS and variable contact time experiments, was carried out on these seeds and beans and gave valuable information on the solid-like and liquid-like components. To our knowledge these seeds and beans have never been previously analysed using this technique. 13C SPE-MAS NMR spectroscopy indicated that the seeds contained more liquid-like components than the beans. In turn the 13C CP-MAS NMR spectra indicated that beans had higher levels of solid-like components than the seeds. These conclusions correlated well with the quantities of liquid-like components and solid-like components that were determined by conventional methods and TGA. Preliminary studies using T1pH experiments on the components present in the seeds and beans led to a few observations. Most interesting is that a model using a two- phase fit in order to determine T1pH values appears to be more accurate than a one-phase model.
AFRIKAANSE OPSOMMING: Groente olies, sade en bone is ‘n onderwerp van groot belang omrede hul kommersiële, voeding en gesondheidswaardes. In hierdie tesis is olie-bevattende voedselprodukte, spesifiek groente-olies, sade en bone geanaliseer. Geselekteerde komponente teenwoordig in klein hoeveelhede in drie lokaal geproduseerde groente-olies, naamlik appelkoos-pit, avokadopeer en makadamia-neut olies is geanaliseer met behulp van 31P KMR spektroskopie. Hierdie komponente, insluitend 1,2 diasielglyserole, 1,3 diasielglyserole en ongebonde vetsure, is vir die eerste keer geïdentifiseer in die 31P KMR spektra van die drie groente olies. Twee benaderings is gebruik vir die hoeveelheids-bepaling van die komponente in die spektra. ‘n Yking-kurwe metode het gebruik gemaak van bekende hoeveelhede konsentrasies standaard komponente vir die opstel van yking-kurwes, terwyl ‘n direkte korrelasie metode gebruik is om die onbekende konsentrasie van komponente in groente olies te bepaal met behulp van ‘n bekende hoeveelheid standaard verbinding teenwoordig in die oplossing. Hierdie metodes het gelei tot die bepaling van die konsentrasies van die komponente gedurende vyf verskillende berging toestande wat ingesluit het: Blootgestel aan lig, in ‘n donker kas, in ‘n donker kas toegevou in tin foelie, bevries by -8 °C en in ’n koelkas by 5 °C. Dit was bevind dat bepaling van die beste bergingstoestand vir elke olie moeilik is aangesien die individuele komponente verskillend geaffekteer word deur die verskeie berging toestande. Die beste bergings toestand oor die algemeen blyk egter om by 5 °C en -8 °C te wees. Sesamsaad, sonneblomsaad, papawersaad en pampoensaad sowel as sojaboontjie, mungboontjie, swartboontjie en pronkboontjie se olie, protein en koolhidraat komponente was geanaliseer met behulp van termogravimetriese analise (TGA) en 13C soliede toestand KMR spektroskopie. Dit was bevind dat die eerste afgeleide van die TGA data waardevolle inligting lewer oor die komponent inhoud van elk van die sade en bone. Hierdie is nog nie vantevore bevind nie. Vir die sade, was die integrasie van ‘n area tussen 270–480 ºC gelyk aan die som van die olie en proteïen inhoud en het goed vergelyk met die waardes verky deur algemene analitiese metodes. Vir die boontjies, was die integrasie van ‘n area tussen 180-590 ºC gelyk aan die som van die olie, protein en koolhidraat inhoud. 13C vaste staat KMR spektroskopie, insluitende SPE-MAS, CP-MAS en variëerbare kontak-tyd eksperimente, was gedoen en het waardevolle inligting gelewer omtrent die solied-agtige en mobiel-agtige komponente. Hierdie sade en bone is tot ons kennis nog nie van te vore met die tegnieke ondersoek nie. 13C SPE-MAS NMR spektroskopie het aangedui dat daar ‘n groter hoeveelheid mobiel-agtige komponente in sade as in bone teenwoordig is. 13C CP-MAS NMR spektroskopie het weer aangedui dat daar ‘n groter hoeveelheid solied-agtige komponente in bone as in sade teenwoordig is. Hierdie gevolgtrekkings het goed vergelyk met die waarnemings verkry deur konvensionele analitiese metodes en TGA. Voorlopige studies op die komponente van sade en bone deur T1pH eksperimente het tot ‘n paar gevolgtrekkings gelei waarvan die mees interessantste was dat ‘n twee-fase model vir die bepaling van T1pH waardes beter resultate lewer as ‘n een-fase model.

Les fruits de coriandre ont été identifiés comme une source riche en huile végétale de haute qualité, à forte teneur en acide pétrosélinique et en huile essentielle. Un système d'extraction innovant a été conçu et développé en utilisant la technologie d'extrusion bi-vis. Il a permis l’obtention d'un produit nouveau, à savoir une huile végétale de coriandre aromatisée et à haute valeur ajoutée, d’un condensat présentant une concentration élevée en huile essentielle et d’un tourteau révélant une forte teneur en protéines. Le tourteau a montré son intérêt en tant que liant naturel pour la production de panneaux de fibres renouvelables issus de la paille de coriandre, un résidu de la culture de la plante, conduisant à des agromatériaux auto-liés et ayant un rapport performance/coût élevé. Les fibres de la paille de coriandre ont également présenté une bonne capacité de renforcement lorsqu’elles étaient utilisées comme charge naturelle dans des biocomposites thermoplastiques à base de polypropylène ou de biopolyéthylène, permettant le moulage par injection de matériaux peu couteux et aux propriétés mécaniques prometteuses. Ce travail présente ainsi une forte contribution à la mise en place d'une véritable bioraffinerie intégrée de la coriandre et à la démonstration de sa mise en oeuvre à une échelle industrielleCoriander fruits of French origin were identified as a rich source of a high-quality vegetable oil, with a high petroselinic acid content, and essential oil. An innovative extraction system was designed and developed using twin-screw extrusion technology and resulted in the recovery of a novel flavored coriander oil with high added value, as well as a hydrosol product with a high essential oil concentration and a press cake with an important protein fraction. The press cake was shown valuable as a natural binding agent for the production of renewable materials from coriander straw, a crop residue, and led to binderless boards with a high performance-cost ratio. Simultaneously, the coriander straw fibers displayed good reinforcing capacity as a natural filler in thermoplastic biocomposites from polypropylene or biopolyethylene, resulting in cost-effective materials with attractive properties. This work thus presents a strong contribution to the setup of a true integrated biorefinery for coriander fruits and its industrial implementation on a relevant production scale

Avaliar a sensibilidade de sementes de pupunha à dessecação, por meio do teste de raios X e do teste de emergência de plântulas, determinando-se os níveis crítico e letal de tolerância à dessecação, foi o objetivo deste estudo. A perda de água das sementes foi monitorada e os tratamentos constituídos pela tentativa de decréscimo de 3% do teor de água do anterior, a partir do inicial (testemunha), até o mínimo de 11%; assim, o número de tratamentos teve relação direta com o teor de água inicial das sementes e cada tratamento foi representado por quatro repetições de 50 sementes. Após a secagem, as sementes foram radiografadas, determinados os espaços internos vazios e submetidas ao teste de emergência de plântulas em areia. As sementes de pupunha ao atingirem 36,4% de teor de água, durante o processo de secagem, têm o seu potencial fisiológico afetado negativamente (teor de água crítico) e, com o avanço do processo de secagem a partir de 12,2% ocorre a morte das sementes. O teste de raios X é eficaz na avaliação da morfologia interna das sementes durante a secagem. À medida que aumenta o espaço interno vazio diminui o potencial fisiológico das sementes e acima de 30% não ocorre a emergência de plântulas.The objective of this study was to evaluate the sensibility of peach-palm seeds to desiccation and determine the critical and lethal levels for tolerating desiccation by using X-ray and seedling emergence tests. Water loss from the seeds was monitored and the treatments consisted of progressive 3% reductions in water content commencing with the control values until a minimum of 11% was reached; therefore, the number of treatments was directly related to the initial seed water content and each treatment was represented by four replications of 50 seeds. After drying, the seeds were X-rayed, the internal empty spaces determined and the seeds submitted to a seedling emergence test in sand. Peach-palm seeds dried to 36,4% of moisture content have reduction on physiological potential (critical level for tolerance desiccation); increased drying after 12.2% results in seed mortality. The X-ray test is effective in internal morphology evaluation of the peach-palm seeds as drying increased. As the internal empty space increases in the seeds, the physiological potential decreases; there is no seedling emergence when the internal empty space is greater than 30%.

A pesquisa teve como objetivo estabelecer uma metodologia específica para a condução do teste de tetrazólio para as sementes de tomate (Lycopersicum lycopersicum L.) com ênfase para o estudo de condições para o preparo e a avaliação das sementes. A pesquisa foi realizada em duas fases: a primeira, utilizando quatro lotes de sementes de tomate do cultivar Bruna, definiu os procedimentos para estimar a viabilidade das sementes; assim, foram testados períodos de hidratação da semente (2, 3 e 4 horas), em duas temperaturas 40oC e 45oC, e de coloração da semente (1, 2 e 3 horas), em solução 0,075% de 2,3, 5 trifenil cloreto de tetrazólio, a 40oC. Paralelamente, foi determinado o teor de água das sementes e conduzidos os testes de germinação e de emergência de plântula. Na segunda etapa, utilizando três lotes de sementes de tomate dos cultivares Débora Max e Acclaim, foram estabelecidos os critérios de avaliação das sementes para estimar o vigor. Paralelamente, foram conduzidos os testes de germinação, de emergência de plântula, de envelhecimento acelerado e de deterioração controlada. Os resultados indicaram que a hidratação das sementes por três horas, a 45oC, associada a três horas de coloração, possibilitou a identificação das estruturas vitais da semente e a classificação dos níveis de viabilidade e de vigor. Dessa forma, é possível concluir que o teste de tetrazólio é eficiente para estimar a viabilidade e o vigor de sementes de tomate; há a possibilidade de reduzir o período de tempo para a realização desse teste.This research was carried out to study procedures for the tetrazolium test to identify viability and vigor of tomato seeds (Lycopersicum lycopersicum L.). In the first experimental stage, using four seed lots from cultivar Bruna, specific studies were carried out to the tetrazolium test for the seed viability evaluation. Then, seed was moistening for two, three and four hours, at 40oC or 45oC, and staining during one, two and three hours, in an aqueous solution 0,075% of 2,3,5 - triphenyl tetrazolium chloride, at 40oC. In the second stage, using three lots each from cultivars Debora Max and Acclaim, the tetrazolium test was carried out for the seed vigor evaluation. The late stage also included germination, seedling emergence, accelerated aging and controlled deterioration tests. From the results, the best conditions were three hours moistening, at 45oC, and staining for three hours. It was concluded that tetrazolium test constitutes an efficient option for the viability an vigor evaluation of tomato seeds; it is possible to reduce the time required for these test execution.

Full textAbstract:
Le calebassier (Crescentia alata) ou jicaro, est un arbre très important dans les systèmes agropastoraux des régions tropicales sèches d'Amérique. Ses fruits contiennent de nombreuses graines consommées traditionnellement, mais malgré son importance, peu d’informations existent sur ses propriétés nutritionnelles et son potentiel industriel.Dans un premier temps les caractéristiques physico-chimiques des graines, des cotylédons ainsi que des coques ont été analysées. Le cotylédon résulte contenir en moyenne 43% de protéines et 38 % de lipide (b.s.), ce qui est comparable à la plupart des graines d’oléagineux. La graine ne contient pas d’inhibiteur de trypsine, peu de phytates et pratiquement aucun sucre non digestible. Une analyse protéomique a révélé que les protéines sont principalement de faible poids moléculaire (~10 kDa), plutôt de type albumine 2S contenant comme le soja jusqu’à 16 % d’acides aminées essentiels. Parmi les lipides, 77.6 % sont des acides gras insaturés, en particulier l'acide oléique.S’agissant d’une graine consommée traditionnellement après torréfaction, cette opération unitaire a été étudié. Pour la première fois a été identifié par chromatographie en phase gazeuse olfactométrie (GC-O) un composé d’arôme caractéristique de la graine, l’éthyl-2-méthyl-butyrate dont la teneur augmente au cours de la torréfaction. Néanmoins, d’autres composés d’arôme tels que les pyrazines et certains aldéhydes contribuent aussi aux notes aromatiques spécifiques et agréables qui se révèlent après torréfaction. Cette opération thermique induit des changements physiques et micro-structurales dont la coalescence des globules gras observés par microscopie à balayage et le gonflement (puffing) qui est à l´origine de l’ouverture de la coque. Ce dernier changement a été exploité pour le décorticage de la graine afin de libérer le cotylédon blanc. Cette opération a été optimisée en fonction de la couleur et le nombre de graines ouvertes avec un modelage cinétique, obtenant un taux d’ouverture de plus de 90% avec une perte de luminance de moins de 10%. Après la torréfaction, un traitement de ré-humidification a été effectué pour durcir le cotylédon et obtenir une meilleure efficacité de décorticage.Les cotylédons ainsi libérés peuvent utilisés pour la fabrication d’un lait végétal qui présente des caractéristiques physico-chimiques, sensorielles et nutritionnelles supérieures à de nombreux laits végétaux présents sur le marché. Une analyse préliminaire a montré que le lait contient plus de 6% de lipides et 4% de protéines et maintient le couleur blanc des cotylédons et l’arôme caractéristique du jicaro. Des études cliniques ont aussi révélé que le lait obtenu a un indice glycémique bas (11). Cela vient confirmer son potentiel comme alternative bon pour la santé, s’agissant d’un lait sans lactose, sans facteurs anti-nutritionnels et avec un indice glycémique basThe calabash tree (Crescentia alata) or jicaro is a very important tree in the agro-pastoral systems of the dry tropical regions of America. Its fruits contain many seeds that have traditionally been consumed. However, despite its importance, little information exists on its nutritional properties and its industrial potential.In the first part of this work, the physicochemical characteristics of seeds, cotyledons and coats were analyzed. The cotyledon contains in average 43% protein and 38% lipid (d.b.), which is comparable to most oleaginous seeds. The seed contains no trypsin inhibitors, few phytates and almost no indigestible sugar. A proteomic analysis revealed that proteins are predominantly of low molecular weight (~ 10 kDa) mainly of albumin type 2S, comprising as soybeans up to 16% of essential amino acids. Among lipids, 77.6% are unsaturated fatty acids, mainly oleic acid.As it is a seed traditionally consumed after roasting, this unit operation was studied. For the first time, a volatile compound characteristic of its aroma, and whose content increases as a result of roasting, the ethyl-2-methylbutyrate, has been identified by gas chromatography-olfactometry (GC-O). Yet, other aroma compounds such as pyrazines and certain aldehydes also contribute to the specific and pleasant aromatic notes which are found after roasting. This thermal operation induces physical and microstructural changes, including the coalescence of fat globules, which was observed by scanning microscopy, and puffing which is at the origin of the opening of the seed coat.This last change has been exploited for the dehulling of the seed in order to isolate the white cotyledon. This operation was optimized regarding the color and the number of opened seeds with a kinetic modeling, obtaining an opening rate of more than 90% with a loss of luminance of less than 10%. After roasting, a tempering treatment was carried out to harden the cotyledon and obtain better dehulling efficiency.The isolated cotyledons can be used for the manufacture of a vegetable milk which has physicochemical, sensory and nutritional characteristics superior to many vegetable milks present on the market. A preliminary analysis showed that the milk contains more than 6% lipids and 4% protein and maintains the white color of the cotyledons and the characteristic aroma of jicaro. Clinical studies have also revealed that the obtained milk has a low glycemic index (11). This confirms its potential as a healthy alternative for a lactose-free milk with no anti-nutritional factors and a low glycemic index

O conhecimento sobre o sistema de cruzamento e a forma como a diversidade genética está distribuída em populações de espécies arbóreas é de fundamental importância para se planejar seu manejo e conservação. Espécies arbóreas pioneiras estão cada vez mais freqüentes dentro e fora dos fragmentos florestais remanescentes. Trema micrantha é uma das primeiras espécies a se estabelecer em áreas abandonadas e Cecropia pachystachya é uma espécie pioneira dióica e seletivamente higrófita. Ambas são polinizadas pelo vento e produzem muitas sementes que são dispersas por animais. Estudou-se a diversidade e estrutura genética e o sistema de cruzamento em populações de ambas espécies e, para T. micrantha, avaliou-se também o banco de sementes como um potencial tampão gênico para a espécie. As populações foram amostradas na Estação Ecológica dos Caetetus (Gália-S.P.) e na Reserva Florestal de Santa Genebra (Campinas-S.P.), onde se amostrou 177 indivíduos de T. micrantha, distribuídos em 6 e 5 subpopulações, e 178 indivíduos de C. pachystachya, em 2 e 3 subpopulações, nos respectivos fragmentos. Os sistemas de cruzamento foram avaliados com base em 24 progênies de 10 indivíduos por progênie de cada espécie. As estimativas para os parâmetros de diversidade genética nas populações de plantas do dossel foram obtidas a partir do polimorfismo de oito locos isoenzimáticos, num total de 20 alelos para T. micrantha e sete locos isoenzimáticos num total de 17 alelos para C. pachystachya. Da mesma forma, utilizou-se 13 locos com 30 alelos para T. micrantha e sete locos com 17 alelos para C. pachystachya, no estudo dos sistemas de cruzamento. Verificou-se que as populações de ambas espécies contêm baixos níveis de endogamia ( f ) de -0,204 e 0,066 em T. micrantha; -0,052 e 0,049 em C. pachystachya, em ambos fragmentos) e alta diversidade ( e H ) de 0,373 e 0,392 em T. micrantha; 0,355 e 0,335 em C. pachystachya, em ambos fragmentos). A divergência genética existente entre populações é menor do que entre subpopulações ( de 0,026 e 0,007, de 0,086 e 0,068, para C. pachystachya e T. micrantha, respectivamente). T. micrantha apresenta sistema de cruzamento misto, com preferência por alogamia ( de 0,966 e 0,819, em ambos fragmentos) e está sujeita a variações na freqüência de cruzamentos endogâmicos ( p θ SP θ m t F de 0,022 e 0,103) e a altas taxas de cruzamentos biparentais ( de 0,653 e 0,605). Sendo espécie dióica, as estimativas de fecundação cruzada obtidas para C. pachystachya não corresponderam às expectativas ( de 0,816 e 0,794). No entanto, as estimativas indicaram que espécie está sujeita a cruzamentos biparentais ( de 0,868 e 0,990). Os resultados sugerem que uma acirrada competição nas etapas de germinação e desenvolvimento de plântulas durante a regeneração de T. micrantha, bem como a distribuição espacial em clareiras e o eficiente fluxo gênico nesta espécie são fundamentais para manter altas taxas de diversidade genética em suas populações.The knowledge about the breeding system and the genetic structure of populations of tree species is of great importance in order to plan their management and conservation. Pioneer tree species are more and more frequent inside and outside remaining forest fragments. Trema micrantha is one of the first tree species to be established in abandoned areas and Cecropia pachystachya is a pioneer dioecious tree and selectively adapted to wet soils. Both species are pollinated by wind and produce seeds that are dispersed by various animals species. We studied the diversity, the genetic structure and the mating system of both pioneer species populations. The seed bank of T. micrantha was also evaluated as a potential genetic buffer for this species. Populations were collected in the Estação Ecológica dos Caetetus (Gália, São Paulo State, Brazil) and in the Reserva Florestal de Santa Genebra (Campinas, São Paulo State, Brazil), where 177 plants of T. micrantha, distributed into six and five subpopulations, and 178 plants of C. pachystachya, distributed into two and three subpopulations were respectively sampled from both fragments. Ten seeds per plant and 24 plants per population were germinated to generate progeny arrays used in the mating system analyses. The estimates for the genetic diversity genetic parameters in the plant populations of the dossel were obtained from eight polymorphic isozyme loci with 20 alleles for T. micrantha and seven isoenzymatic loci with 17 alleles for C. pachystachya. Similarly, 13 loci with 30 alleles for T. micrantha and seven loci with 17 alleles for C. pachystachya were used in the mating system study. The results showed that populations of both species have low levels of inbreeding ( = 0.204 and 0.066 for T. micrantha; = -0.052 and 0.049 for C. pachystachya, in both fragments, respectively) and high diversity ( f f e H = 0.373 and 0.392 for T. micrantha; e H = 0.355 and 0.335 for C. pachystachya, in both fragments). The genetic divergence among populations was lower than among subpopulations ( = 0.026 and 0.007; = 0.086 and 0.068, for C. pachystachya and T. micrantha, respectively). T. micrantha presents a mixed mating system, with preference to outcrossing ( = 0.966 and 0.819, in both fragments) and is subject to variations in the inbreeding frequency and high rates of biparental mating ( = 0.653 and 0.605 in both fragments, respectively). The estimates obtain for C. pachystachya did not correspond to the expectations of a dioecious species ( = 0.816 and 0.794 in both fragments). A significant proportion of related individuals were observed ( p θ SP θ m t p r m t s t m t − = 0.072 and 0.128, both fragments), indicating a spacial structure of individuals under the species natural condition. The estimates showed that the great majority of C. pachystachya progenies are composed of full-sib matings ( = 0.868 and 0.990 in both fragments), resulting from biparental matings. Besides, the results suggest that a tough competition in the phases of germination and seedling development during the regeneration of T. micrantha, as well as the spatial distribution in gaps and the efficient gene flow are important in order to maintain high rates of genetic diversity in its populations.

O projeto "Avaliação de Aspectos da Dinâmica de Florestas Restauradas, com Diferentes Idades", teve como objetivo geral identificar indicadores que possam ser utilizados na avaliação e monitoramento de áreas restauradas, através do restabelecimento da resiliência nessas áreas.

Para avaliação do banco de sementes, realizaram-se 2 coletas de solo e de folhedo (abr/01 e jun/01), por unidade amostral (0.25x0.25m), na profundidade de 0.05m. Para avaliação dos indivíduos jovens regenerantes, foram amostrados todos os indivíduos entre 0.30-1.30m de altura, em 2 sub-parcelas (1x1m) por parcela amostral (mai/01 e nov/01). Foram realizados cálculos de freqüência e de densidade absoluta através do teste do logaritmo da verossimilhança (teste G). As análises de variância (teste F) foram realizadas para verificar o crescimento em altura dos indivíduos amostrados nas diferentes avaliações. Quando diferenças significativas foram encontradas, aplicou-se o teste de Tukey a 5% de probabilidade para determinar entre quais grupos as médias diferiam significativamente. O fluxo de propágulo mensurado nas áreas em estudo, durante o período de oito meses, apresentou diferença altamente significativa (P = 0,001), ou seja a chuva de sementes apresentou-se de forma heterogênea, sendo que as espécies arbóreas predominaram sobre as herbáceas, lianas e arbustivas. A investigação do banco de sementes nas três áreas revelou variações altamente significativas (P = 0,001) na densidade de sementes nas duas avaliações (jan/01 e jun/01). Constatou-se que o número de espécies herbáceas que germinaram no banco de sementes nas três áreas tendeu a diminuir e as arbóreas a aumentar com a idade da restauração. Os indivíduos jovens amostrados nas áreas em estudo são compostos predominantemente por espécies arbóreas. A proporção de indivíduos jovens presentes nas avaliações apresentou diferença significativa (P = 0,32), entre as avaliações, isto é, houve um recrutamento de novos indivíduos na segunda avaliação. Os resultados obtidos neste estudo nos leva a concluir que recuperar uma área degradada não depende apenas do plantio de espécies nativas mas depende: i) do histórico do uso da terra a ser restaurada, ii) do grau de isolamento e iii) do monitoramento e da avaliação dos projetos de restauração, permitindo dessa forma, definir intervenções de manejo que garantam o sucesso do empreendimento em termos de perpetuação das áreas restauradas.The project "Evaluation of aspects of the dynamics in restored forests, with different ages" had as main aim to define indicators that can be used in the evaluation and monitoring of restored areas, through the reestablishment of the resilience in those areas. This task was performed in three restored areas: Ester Sugar Mill, in Cosmopolis SP, having 9ha been submitted to native and exotic species planting between 1955 and 1960 (@ 46 years); Experimental Area at Plantec, in Iracemapolis SP, with 1ha of planted area, including native and exotic species, in 1992 (@ 9 years); Dedini Agro industry Area, in Santa Cruz das Palmeiras SP, with 1ha submitted to native species planting between 1995 and 1997 (@ 6 years). These areas differ among themselves from implementing time, number of planted species and restoration methods. In each area, 10 samples of 10x20 m were selected, with 6 sub samples of 0.5x0.5 m, and three repetitions for each treatment analyzed. For evaluating the seeds rain, 3 collectors of 0.5x0.5 m were installed for each sample (30 collectors per area), with monthly samplings. For evaluating the seeds bank, 2 samplings of soil and foliage were performed (April/01 and June/01) per sample (0.25x0.25 m), at 0.05 m depth. For evaluating the regenerating young individuals, all the individuals between 0.30 1.30 m height were sampled, in 2 sub samples (1x1 m) per sample (May/01 and November/01). Frequency and absolute density calculations were performed through the logarithm of truthfulness test (test G). The variation analysis (Test F) were performed for verifying the height growth of the individuals sampled in different evaluations. When significant differences were found, the probability Tukey test at 5% was applied for determining between which groups the averages differed significantly. The propagation flow measured in the areas, during an 8- month period, presented highly significant differences (P = 0.001), i.e., the seeds rain occurred heterogeneously, when the arboreal species overwhelmed the herbaceous, lianas and bushy ones. The investigation of the seeds bank on the three areas revealed highly significant variations (P = 0.001) in the seeds density in both evaluations (January and June/01). It has been noted that the number of herbaceous species germinated on the seeds banks on the three areas tended to diminish, and the arboreal, to increase along the restoration phase. The young individuals shown on the study areas are mainly arboreal species. The young individuals proportion present at the evaluations presented significant variations (P = 0.32), between the evaluations, i.e., there was a recruiting of new individuals on the second evaluation. The results on this study lead us to conclude that for recovering a degraded area does not only depend on the planting of native species but depends on i) the studying of the land use, ii) the isolation grade and iii) the monitoring and evaluation of the restoration projects, thus allowing the definition of the intervening handlings that can guarantee the success of the undertaking in terms of the restored areas perpetuation.

AbstractGas flaring is a key contributor of greenhouse gases that causes global warming and climate change. Adaptation measures for tackling impacts of climate change have gained much research interest. This chapter assessed vegetable farmers’ perception of gas flaring and the effect of biochar remediation on the heavy metal composition of cultivated Telfairia occidentalis. A gas-flared area, Ohaji/Egbema L.G.A of Imo State, and a non-gas-flared area, Umudike, Ikwuano L.G.A, were selected for this research. Structured questionnaire was used to elicit information from 120 respondents. Soils were collected from the study sites and transported to the greenhouse. Five different rates, 0 t ha−1, 7.1 t ha−1, 13.9 t ha−1, 20.9 t ha−1, and 28.0 t ha−1, of palm bunch biochar were applied to the soils in plastic buckets. After 2 weeks of mineralization, two viable seeds of Telfairia occidentalis were planted in each bucket and watered every other day for 8 weeks. The result revealed that 63% of vegetable farmers where female, while 37% were male in the gas-flared area. A total of 97% of the farmers had knowledge of gas flaring. A total decrease of 55% percent income, 90% yield, and 67% market quality of vegetable farmers was attributed to gas-flared activities. The plant height of cultivated vegetables increased every 2 weeks with greater increase in the test plant. Heavy metal concentration (Pb, and Cr) decreased with increasing biochar rate and was significantly lower for 28.0 t ha−1. Biochar can enhance soil fertility and help immobilize heavy metals. The effect of biochar application on the heavy metal composition is dependent on the rate of application. Biochar use could be a cheap adaptation measure in the face of a changing climate.

Full textAbstract:
Recent advances in molecular breeding techniques along with developing tools for Genomics and Proteomics are delivering new oil seed profiles for industrial applications. Ultra high Oleic, Erucic and blends including Hydroxy fatty acids are now, or will be shortly, available in a variety of oilseed crops including Soybean and Canola as well as Flax. As a result, vegetable oils need to be re-examined by industry for specific applications. Feedstocks and base oils derived from oil seeds are renewable as well as biodegradable. A brief summary of recent progress is presented together with a description of new research into the development of an alternative source of Hydroxy fatty acids to replace castor oil and an overview of an enzyme engineering approach to create new enzymes for seed oil modification.

Full textAbstract:
This study leveraged existing data infrastructure and relationships from the Feed the Future Senegal Naatal Mbay (“flourishing agriculture”) project, funded by the US Agency for International Development (USAID) and implemented by RTI International from 2015 to 2019. The research informed and empowered farmer organizations to track and respond to rural households in 2020 as they faced the COVID-19 pandemic. Farmer organizations, with support from RTI and local ICT firm STATINFO, administered a survey to a sample of 800 agricultural households that are members of four former Naatal Mbay–supported farmer organizations in two rounds in August and October 2020. Focus group discussions were conducted with network leadership pre- and post–data collection to contextualize the experience of the COVID-19 shock and to validate findings. The results showed that farmers were already reacting to the effects of low rainfall during the 2019 growing season and that COVID-19 compounded the shock through disrupted communications and interregional travel bans, creating food shortages and pressure to divert seed stocks for food. Food insecurity effects, measured through the Household Food Insecurity Access Scale and cereals stocks, were found to be greater for households in the Casamance region than in the Kaolack and Kaffrine regions. The findings also indicate that farmer networks deployed a coordinated response comprising food aid and access to personal protective equipment, distribution of short-cycle legumes and grains (e.g., cowpea, maize) and vegetable seeds, protection measures for cereals seeds, and financial innovations with banks. However, food stocks were expected to recover as harvesting began in October 2020, and the networks were planning to accelerate seed multiplication, diversify crops beyond cereals, improve communication across the network. and mainstream access to financial instruments in the 2021 growing season. The research indicated that the previous USAID-funded project had likely contributed to the networks’ COVID-19 resilience capacities by building social capital and fostering the new use of tools and technologies over the years it operated.
