Abstract:

SUMMARY Purpose Although damage to the structural integrity of the tooth is not usually considered a significant problem associated with tooth bleaching, there have been some reported negative effects of bleaching on dental hard tissues in vitro. More studies are needed to determine whether the observed in vitro effects have practical clinical implications regarding tooth structural durability. Objectives This in situ study evaluated the effect of 10% and 15% carbamide peroxide (CP) dental bleach, applied using conventional whitening trays by participants at home, on the fracture toughness of dentin. Methods Ninety-one adult volunteers were recruited (n ≈ 30/group). Compact fracture toughness specimens (approximately 4.5 × 4.6 × 1.7 mm) were prepared from the coronal dentin of recently extracted human molars and gamma-radiated. One specimen was fitted into a prepared slot, adjacent to a maxillary premolar, within a custom-made bleaching tray that was made for each adult participant. The participants were instructed to wear the tray containing the dentin specimen with placebo, 10% CP, or 15% CP treatment gel overnight for 14 nights and to store it in artificial saliva when not in use. Pre-bleach and post-bleach tooth color and tooth sensitivity were also evaluated using ranked shade tab values and visual analogue scales (VASs), respectively. Within 24–48 hours after the last bleach session, the dentin specimens were tested for fracture toughness using tensile loading at 10 mm/min. Analysis of variance, Kruskal-Wallis, χ2, Tukey's, and Mann-Whitney U tests were used for statistical analysis. The level of significance was set at p<0.05 for all tests, except for the Mann-Whitney U tests, which used a Bonferroni correction for post hoc analyses of the nonparametric data (p<0.017). Results The placebo, 10% CP, and 15% CP groups contained 30, 31, and 30 participants, respectively. Mean fracture toughness (+ standard deviation) for the placebo, 10% CP, and 15% CP groups were 2.3 ± 0.9, 2.2 ± 0.7, and 2.0 ± 0.5 MPa*m1/2 respectively. There were no significant differences in mean fracture toughness results among the groups (p=0.241). The tooth sensitivity VAS scores indicated a significantly greater incidence (p=0.000) and degree of tooth sensitivity (p=0.049 for VAS change and p=0.003 for max VAS) in the bleach groups than in the placebo group. The color change results showed generally greater color change in the bleach groups than in the placebo group (p=0.008 for shade guide determination and p=0.000 for colorimeter determination). Conclusions There were no significant differences in in situ dentin fracture toughness results among the groups. The results of this study provide some reassurance that dentin is not overtly weakened by the bleaching protocol used in this study. However, the lack of a statistically significant difference cannot be used to state that there is no effect of bleach on dentin fracture toughness.

Abstract:

The effect of bulb storage and forcing temperatures on growth, flowering, and inflorescence development and the death of inflorescence (blast) of Lachenalia aloides Engl., `Pearsonii' was investigated. Following development of about 5 florets, bulbs were stored at 10, 12.5, 15, 20, and 25 °C for 15, 30, or 45 days and forced in greenhouses at 17/15 °C and 21/19 °C. Flowering was accelerated, and leaf length and floret number were reduced, when bulbs were stored at 10, 12.5, or 15 °C for 45 days compared to storing at 20 or 25 °C. Flowering was further accelerated by forcing at 17/15 °C compared to 21/19 °C. When bulbs were stored at 10, 15, 20, or 25 °C for 4 weeks and grown in greenhouses at 17/15 °C, 21/19 °C, 25/23 °C, and 29/27 °C, the incidence of inflorescence blast was increased when bulbs were stored at 10 and 15 °C and forced at 25/23 °C compared to low temperatures. Bulbs were forced in greenhouses maintained at 18/16 °C, 22/20 °C, or 26/24 °C for 12 weeks. During forcing, plants were subjected to constant or alternating forcing temperatures at 4-week intervals. Inflorescence blast occurred when the temperature was 26/24°C during the first 4 weeks after potting. Storing Lachenalia bulbs at 10&#176 to 15 °C before potting then forcing at 17/15 °C accelerated flowering and produced quality plants with short leaves and floral stems. Inflorescence development during bulb 10 °C treatment and inflorescence blast that occurred after only 3 days of 35 °C was demonstrated using scanning electron microscopy and magnetic resonance imaging techniques.

Abstract:

In this study, phosphorus (P) strength [(full strength: 1×-P, half strength: 0.5×-P and zero strength: 0×-P)] and root zone temperature (10 and 15 °C RZT) were investigated in red romaine lettuce to determine their effects on anthocyanin content. This experiment was conducted using a deep-flow technique (DFT) hydroponic system in a greenhouse during the winter in Gangwon province in the Korea Republic. The treatments were 1×-P (15 and 10 °C RZT), 0.5×-P (15 and 10 °C RZT) and 0×-P (15 and 10 °C RZT). The results showed that the P (phosphorus), K (potassium) and Ca (calcium) accumulation contents were lower in the 0×-P -treated red romaine lettuce leaves than in the other treatments. The maximum red romaine lettuce yields per plant, leaf number and leaf length were exhibited during the 1×-P at 15 °C RZT treatment. In 0×-P at 10 °C, RZT treatment showed lower leaf color values of L*, b*, chrome, ºh and higher leaf color a* values. Moreover, in the 0×-P treatment at 10 °C RZT, the leaf chlorophyll content (SPAD), chlorophyll a, chlorophyll b and chlorophyll total were the lowest. Anthocyanin content was the highest in the 0×-P treatment, followed by 0.5×-P and 1×-P treatments at both 15 and 10 °C RZT. Regardless of the P intensity treatment, anthocyanin content was higher at 10 °C RZT than at 15 °C RZT. In summary, the 1×-P at 15 °C RZT treatment is the best for red romaine lettuce leaf yield, and the 0×-P at 10 °C RZT treatment is the best for lettuce leaf anthocyanin content.

Abstract:

Objective: This study aimed to determine the stability of microspheres of Sargassum plagyophyllum (brown seaweed) after preparation using spraydrying with maltodextrin DE 10–15 and during drying and storage.Methods: Aqueous extracts of brown seaweed were formulated into microspheres using maltodextrin DE 10–15 as a coating agent. For increasing thestability of polyphenol compounds, spray drying was performed with an inlet temperature of 110°C. Four microsphere formulations were producedusing maltodextrin DE 10–15 at concentrations of 0%, 5%, 10%, and 15%. The resulting microspheres were then characterized in the assessments ofmoisture contents, particle size distributions, pH, total phlorotannin contents, and antioxidant activity, and surface morphology was analyzed usingscanning electron microscope analyses.Results: Powders that were produced with 0% and 15% maltodextrin were more stable at 4°C±2°C than at 28°C±2°C and 40°C±2°C. At the lowesttemperature, phlorotannin contents were maintained in powders that were prepared with 15% maltodextrin but were decreased by 10% in powdersthat were prepared without maltodextrin.Conclusion: Maltodextrin DE 10–15 is a suitable coating agent for dry formulations of S. plagyophyllum powder and maintained stability during spraydrying at 110°C and during storage for 2 months at 4°C±2°C.

Abstract:

Commercially cooled bulbs of five genetically dwarf Asiatic hybrid lilies were stored frozen at -2 C. Every 4 weeks for a total of 40 weeks, they were potted and forced in controlled environment chambers at 10, 15, 20, or 25 C. For each temperature, days from the time of potting to shoot emergence, visible bud appearance, and anthesis generally decreased as storage time increased. The number of flowers per plant and plant height were not significantly affected by storage time. Compared with those at 15, 20, or 25 C, plants at 10 C required significantly more time from potting to shoot emergence, visible bud, and anthesis. However, the temperature effects on forcing time were not linear. There was a 30-50 day decrease from potting to anthesis when temperature was increased from 10 to 15 C, but there was only a decrease of about 10 days when temperature was increased from 15 to 20 C. In contrast, there was no significant difference in forcing time between plants at 20 and 25 C. This indicates there is no need to force these lilies above 20 C. Plants at 25 C had more aborted flower buds than those at 10, 15, or 20 C. Plants at 10 C were taller then those at 15, 20, or 25 C.

Abstract:

The peak of germination of autumn-sown seeds of Portulaca oleracea was between 21 May and 21 June, when mean daily maximum and minimum temperatures were 30.7 and 17.4 °C, respectively. Fresh seeds collected in October germinated to 13 and 94% at 30:15 and 35:20 °C thermoperiods, respectively, in light, and to 0% in darkness. Seeds were buried in October 1975 and exhumed in December 1975 through September 1976. In light, exhumed seeds germinated to 69–100% at 30:15 and 35:20 °C,to 1–80% at 20:10 °C, and to 0–52% at 15:6 °C; in darkness they germinated to 5–55% at 30:15 and 35:20 °C and to0% at 20:10 and 15:6 °C. Germination at 20:10 °C did not exceed 50% until mid-April, and it did not exceed 50% at 15:6 °C until June. Fresh seeds were buried at 5, 15:6, 20:10, 25:15, 30:15, and 35:20 °C, and after 0, 1, 3, and 5 months, seeds from each temperature were tested in light and darkness at the five thermoperiods. The minimum temperature at which 50% or more of the seeds germinated in light decreased with an increase in afterripening temperature. The high temperature requirement for complete afterripening and for germination of partially afterripened seeds prevents germination of this summer annual in temperate regions until late spring and early summer.

Abstract:

Lagurus ovatus is an annual grass typical of sandy coastal soils, wide-spread in southern Europe. The color and texture of the inflorescence have such features that give good qualities as dry flower. In this work we have studied the germination capacity of Lagurus ovatus in different conditions of temperature, light and salinity. Seeds harvested in of the province of Murcia (Southeast of Spain) were tested in germination chambers with constant temperatures (5, 10, 15, 20, 25 and 30 °C) and combined temperatures (20/30, 15/25, 10/20 and 5/15 °C). For each treatment, the photoperiod was 12 hours and total darkness. The results showed that total darkness was required to germination and the highest germination were obtained with constant temperatures of 10°C (90%) and 15°C (66%). Temperatures above or below reduced significantly the final germination. With alternate temperatures, the highest values were recorded when at least for 12 hours the temperature was 10 °C or 15 °C (5/15, 10/20 and 15/25 °C) 87%, 93%, and 88% respectively. Once calculated the optimum temperature a salinity experiment was carried out to determine how this parameter affected germination. The assay was carried out at 10/20 °C. The seeds were watered with a NaCl2 solution of: 0, 2.5, 5, 7.5, 10, 12.5, 15 and 17.5 dS·m-1. The greatest germination was obtained in non-saline control (88%) and its was linearly reduced with increases in salinity to 10 dS·m-1 (4%). No germination was registered from 12.5 to 17.5 dS·m-1. When non-germinated seeds were transferred to distilled water after the exposure to salinity, rates of germination were very high in all cases. This work was supported by the CICyT of Spain (project AGL2000-0521).

Abstract:

Development, growth, and survival data derived from laboratory experiments are provided for Lepeophtheirus salmonis, a common ectoparasite of wild and sea-farmed salmonids. The mean development time of eggs was 419·1 hours (17·5 days) at 5°C, 207·1 hours (8·6 days) at 10°C, and 130·8 hours (5·5 days) at 15°C. Development from the first nauplius to the infectious copepodid stage took 222·3 hours (9·3 days) at 5°C, 87·4 hours (3·6 days) at 10°C, and 44·8 (1·9 days) hours at 15°C. Development from the egg to the adult male took 40 days, and from the egg to the adult female 52 days at 10°C. No egg development occurred at 10‰ salinity. At 15‰ eggs developed but failed to produce active nauplii. At higher salinities (20–3‰) active nauplii were produced, but copepodids were only obtained at 30‰. Copepodids survived for less than 1 day in waters with a salinity of 10‰ or less. At higher salinities (15–30‰) and temperatures of 5,10, and 15°C average survival times ranged between 2 and 8 days.

The number of colonies of the Pseudomonas strain exceeded 9 log CFU/ml under all conditions tested. The pathogen grew better as the temperature increased from 10 to 15 and 25°C and grew better in pure culture than in mixed cultures. Pseudomonas sp. inhibited E. coli O157:H7 in cocultures with glucose at 10°C, while at 15°C the pathogen exhibited a biphasic pattern of growth with an intermediate inactivation period. Pathogen inhibition was much weaker in cocultures grown without glucose at 10 to 15°C and, irrespective of glucose, at 25°C. These results indicate that glucose enhances the growth inhibition of E. coli O157:H7 by some Pseudomonas spp., potentially due to its rapid uptake and conversion to gluconate, at low (≤15°C) temperatures.

Abstract:

In tubers `Kennebec' and `Russet' were applied acetylene, carbide and ethylene to promote sprouting, subsequently the tubers were stored at temperatures of 10 and 15 C. The experiment was a completely randomized, factorial design. The evaluations were done weekly. `Kennebec' sprouted from the second week of applied the treatments to 10 and 15 C while `Russet' sprouted only to 15 C. In the fourth evaluations the effect of promoters was not significantly different to the control. `Kennebec' at 10 C showed greater percentage of sprouting and number of sprout/tuber with respect to `Russet', but at 15 C were not detecte significant differences between the cultivars for these parameters. Number of sprout/tuber in `Kennebec' was not affected by the promoters but `Russet' treated with acetylene and carbide at 10 C showed the largest number of sprout/tuber. The greater sprout length was presented by `Kennebec' in both temperatures.

Abstract:

Fertility of boar spermatozoa as determined following artificial insemination seems to be maintained during liquid preservation at 10–15°C for several days, although prolonged liquid preservations reduce the pregnancy rate rapidly. However, it is not clear if spermatozoa can penetrate into oocytes in an IVF system even after a prolonged liquid preservation. Oxidative stress could also be one of the possible detrimental factors in liquid preservation of spermatozoa. In the present study, fertility of liquid-preserved spermatozoa was examined using an IVM-IVF system. Whether cysteine can improve the fertility was also determined. Spermatozoa (from four Berkshires) was resuspended at 1×108 cells mL−1 in Modena solution containing 15% (v/v) boar seminal plasma and 0 or 5mM cysteine after washing 3 times. Sperm suspensions (1mL) were then preserved at 10°C for 22 days following a program for cooling down (to 15°C for 4h, keeping at 15°C for 12h and then to 10°C for 6h). At Days 1, 8, 15 and 22 after the start of preservation, spermatozoa (5×105 cells mL−1) were co-cultured with IVM oocytes in an IVM/IVF system (Funahashi et al., 1997 Biol Reprod 57, 49–53). Viability and functional status of spermatozoa were also examined at Days 8 and 15 of preservation by using LIVE/DEAD sperm viability kit and CTC fluorescence assay. Data (mean±SEM) from 4–6 replicates were analyzed by ANOVA and Fisher’s protected LSD test. When spermatozoa that had been preserved without cysteine (Cys−) were used, penetration rates were not different (P>0.05) from those with cysteine (Cys+) at Day 8 of preservation (91.4±3.4% in Cys− and 99.3±0.7% in Cys+), but lower (P<0.02) at Days 15 and 22 (72.6±13.6% and 33.8±8.4% in Cys−; 94.8±2.1% and 71.1±10.8% in Cys+, respectively). Both viability and proportion of uncapacitated live cells were higher (P<0.05) in Cys+ than Cys− at Days 8 and 15. These results demonstrate that boar spermatozoa can penetrate into oocytes in vitro even after a liquid preservation at 10°C for 22 days and that cysteine can improve the viability and penetrability in vitro of spermatozoa during liquid preservation.

Abstract:

When plants of the uniculm 'gigas' wheat line 492 were grown at 15/ 10°C, all plants were severely stunted in long days (LD) but normal in short days (SD). The results of reciprocal transfers between SD and LD indicate that line 492 plants pass through a stage which is very sensitive to LD at 15/ 10°C, between about 14 and 27 days after sowing, just before double ridge formation at the shoot apex. LD during that interval caused stunting in most plants whereas SD at that stage allowed all plants to develop normally. Transfers between temperature regimes of 15/10°C and 24/19°C under LD also indicated that the period just prior to double ridge formation was critical for stunting. In the uniculm line 492 stunting in LD was caused by temperature regimes cooler than 21 /16°C;, whereas in the oligoculm line 380 the main shoots of most plants were normal even at 15/ 10°C.

Abstract:

Continuous Stirred Tank Reactors (CSTRs), operated in batch mode, were used to evaluate the feasibility of psychrophilic (low temperature) digestion of perennial rye grass in a long term experiment (150 days) for the first time. The reactors were operated in parallel at 3 different temperatures, 10, 15 and 37 °C. Hydrolysis, acidification and methanogenesis were assessed by VS degradation, by soluble chemical oxygen demand (SCOD) and volatile fatty acids (VFA) production, and by methane production, respectively. Hydrolysis was the rate-limiting step at all temperatures and the rates and extent of hydrolysis were considerably lower at 15 and 10 °C, than at 37 °C. The total VS degradation was 53%, 34% and 19% at 37, 15 and 10 °C, respectively. Acidification was not affected by temperature and VFA production and consumption was balanced in all cases, except at 10 °C. Methane yields were 0.215 m3 CH4 kg−1 VS−1 added, 0.160 m3 CH4 kg−1 VS−1 added and 0.125 m3 CH4 kg−1 VS−1 added at 37, 15 and 10 °C, respectively. Methanogenesis was not strongly affected at 15 °C but it became rate-limiting at 10 °C. Overall, the solid degradation and methane production performance under psychrophilic conditions was encouraging and greater than previously reported. Considering the non-acclimated, mesophilic nature of the inoculum, there are grounds to believe that low-temperature anaerobic digestion of grass could be feasible if coupled to efficient hydrolysis of the biomass.

Abstract:

The increased sugar and starch in crowns and roots during hardening is considered a limiting factor for the acquisition of cold tolerance in alfalfa (Medicago sativa L.). We wanted to determine the effect of a decrease in carbohydrate on cold tolerance. Alfalfa plants (Medicago sativa L.) were hardened at 1 °C or −2 °C during the day and at 10 °C or 15 °C during the dark while control plants were kept continuously at 1 °C or −2 °C. Hardening alfalfa at 10 °C and 15 °C during darkness decreased the total sugar content while it increased at 1 °C and −2 °C. However, frost tolerance and growth of the plants were not changed by raising the night temperature to 10 and 15 °C. The sugar increase corresponded in general to a starch degradation, mainly in the crowns. In plants hardened at −2 °C the proline content was higher in the leaves and lower in crowns. The opposite was observed in plants hardened at 10 and 15 °C during darkness. However, during hardening at −2 °C, we observed the desiccation of leaves and an increase in the proline content. We discuss the role of sugars as promoting agents for the acquisition of frost tolerance. Key words: Alfalfa, frost tolerance, sugars, starch, proline, hardening

Abstract:

AbstractMountain pine beetle (Dendroctonus ponderosae Hopkins) population dynamics, as well as potential for outbreaks and resulting tree mortality, are related in part to habitat temperature. As a first step in development of a life-stage, event-oriented simulation model, we have modeled the temperature-dependent development of the egg stage. The completed model includes a full description of variation in developmental rates and is capable of predicting duration and eclosion patterns for any temperature regime. This model was parameterized using data obtained from constant-temperature experiments at temperatures of 8, 10, 12.5, 15, 20, 25, and 30°C. Validation experiments were conducted for constant temperatures of 15, 17.5, 22.5, and 27.5°C and for variable-temperature regimes of 15±5 and 15±10°C. Validation results indicated that the model is capable of accurately describing the emergence curve for constant temperatures below 27.5°C. The model also faithfully represents emergence under variable temperatures of 15 ± 10°C. Potential reasons for lack of model fidelity in describing emergence at constant high temperatures and for 15 ± 5°C are discussed in the text.

Abstract:

The effect of the different metal atomic ratios deposited on Vulcan XC-72R on ethanol electrooxidation reaction were investigated by producing of the ternary catalysts (PtRuSn/C and PtRuNi/C) in various atomic ratios (75:20:5, 75:15:10, 75:10:15, 75:5:20). All catalysts were prepared via polyol process. The nominal atomic ratios of the metals on the support were confirmed by EDX-SEM. The cyclic voltammetry was used to investigate the electrocatalytic activity of the catalysts. It was found that PtRuSn/C (75:10:15) showed the highest maximum current density of 3.25 mA/cm2 among all Sn containing catalysts. However, PtRuNi/C (75:5:20) also exhibited the high maximum current density of 2.66 mA/cm2 which was the maximum current density for Ni containing catalysts. Moreover, PtRuNi/C (75:5:20) exhibited the best activity and stability for ethanol electrooxidation reaction as showed in chronoamperometry tests. The current density at 3000 s was 0.54 mA/cm2. The size of the catalysts was about 1.9-3 nm measured by TEM. The catalyst also presented smaller particle size and better catalyst dispersion among all ternary catalysts. The addition of Sn facilitated the C-C bond breaking in molecule of ethanol while the addition of Ni facilitated better stability.

Abstract:

The influence of temperature and leaf wetness duration on infection of spring onion (Japanese bunching onion) leaves by Puccinia allii was examined in controlled-environment experiments. Leaves of potted spring onion plants (Allium fistulosum cv. Yoshikura) were inoculated with urediniospores and exposed to 6.5, 10, 15, 22, or 27 h of wetness at 5, 10, 15, 20, or 25°C. The lesion that developed increased in density with increasing wetness duration. Relative infection was modeled as a function of both temperature and wetness duration using the modified version of Weibull's cumulative distribution function (R2 = 0.9369). Infection occurred between 6.5 and 27 h of leaf wetness duration at 10, 15, 20, and 25°C and between 10 and 27 h at 5°C, and increased rapidly between 6.5 and 15 h of wetness at 10, 15, and 20°C. At 25°C, few uredinia developed regardless of the wetness duration. Parameter H, one of eight parameters used in the equation and which controls the asymmetry in the response curve, varied markedly according to the temperature, so that the model could be improved by representing H as a function of wetness duration (R2 = 0.9501).

Abstract:

Bare-root Phalaenopsis Blume orchids are frequently shipped by air freight intercontinentally. It was not known how temperature and duration in shipping affect their subsequent performance during greenhouse production. On 15 Sept., container-grown plants of vegetatively propagated Phalaenopsis (Atien Kaala Group) ‘TSC 22’ were removed from pots and individually weighed immediately. These bare-root plants were packed in cartons with shredded newspaper and placed in growth chambers at 15, 20, 25, or 30 °C in darkness. After 4, 7, and 14 days, one-third of the plants were removed from each temperature treatment, weighed, planted in pots, and then placed in a greenhouse. Weight loss increased with increasing air temperature and duration in storage. Chilling injury (CI) was more severe at 15 °C than 20 °C storage temperature and was progressively more severe as storage duration increased from 4 to 14 days. Plants had no sign of CI at 25 °C or 30 °C regardless of storage duration. Leaf loss was most severe on plants stored at 15 °C for 7 days (three leaves) or 14 days (five leaves) or at 30 °C for 14 days (three leaves). Storing plants 14 days or less between 15 °C and 25 °C did not affect the time of spiking (emergence of the flowering shoot), but at 30 °C, spiking was delayed by 5 to 8 days regardless of the duration. Storage resulted in reduced flower count, but not flower size, regardless of temperature and duration. In a second experiment, potted Phalaenopsis plants of the same clone were thermal-acclimatized in growth chambers in mid-September for 10 days at 25 °C followed by another 10 days at 20 °C before being stored in pots or bare-root at 15 °C, 20 °C, 25 °C, or 30 °C for 10 days. Thermal acclimatizing at 25 °C and 20 °C reduced the severity of CI and leaf loss after being stored for 10 days at 15 °C either bare-root or in pots, but did not reduce leaf loss resulting from heat at 30 °C. Repotting or storing bare-root plants did not affect spiking or flowering date under otherwise similar conditions. Nondisturbed plants in pots stored at temperatures between 20 °C and 30 °C for 10 d had higher flower count as compared with bare-root plants that were similarly stored. Spiking of nonacclimatized, bare-root plants was delayed after 10 days at either storage temperature, whereas flowering was delayed by 15 °C and 30 °C only. Bare-root Phalaenopsis orchids should be shipped near 25 °C during the warm period of the year and between 25 °C and 15 °C in the late fall through early spring to avoid CI or heat stress.

Abstract:

Controlled environment was used to simulate three chilling levels to assess differences in seedling growth of four cowpeas (Vigna unguiculata L.Walp), IT82E-18, IT82E-16, Pinkeye Purple Hull and MN13. Genotypes chilled at 14/10 °C, 15/10 °C, and 16/10 °C, (day/night) for 7 days after planting (DAP) did not differ in percent seedling emergence, which showed a maximum of 6%. At 14 DAP, genotypes differed in percent emergence at the 15/10 °C and 16/10 °C temperatures, with ranges of 34% to 51% and 61% to 86%, respectively. By 21 DAP, cowpeas at these two chilling levels had ranges of 57% to 90% and 79% to 94% emergence, respectively, and showed significant differences. At the two lower chilling regimes, the radicles failed to develop secondary roots and the seed coats remained attached to some of the primary leaves. These were generally chlorotic except for IT82E-16 at 15/10 °C. Genotypes at the highest chilling level developed secondary roots and green primary leaves, which were twice the size of those at 15/10 °C. When plants from the three chilling regimes were removed to a warm greenhouse, the leaves became green and secondary roots developed within a week. These results indicate that root development was more sensitive to the chilling temperatures than seedling emergence.

Abstract:

The fluorescence of 4-methylumbelliferyl beta-D-galactopyranoside (MeUmbGalp) was quenched in the presence of cold agglutinin, showing that there was binding between MeUmbGalp and cold agglutinin. That binding was saccharide-specific. By using this quenching phenomenon, the association constants (Ka) of the binding of cold agglutinin at different temperatures (10 degrees C and 15 degrees C) to MeUmbGalp and also the number of binding sites were calculated. The Ka values were found to be 2.63 x 10(3) M-1 at 10 degrees C and 1.58 x 10(3) M-1 at 15 degrees C. Though there is a change in Ka values, the number of binding sites was calculated to be six at both temperatures (10 degrees C and 15 degrees C). From the Ka values the thermodynamic parameters (free energy, enthalpy and entropy) of the binding were derived, and analysis of the data indicated that the binding is spontaneous, exothermic and hydrophobic in nature.

The period of discharge decreased as temperature increased from 10 to 25°C. However, daily discharge increased as temperature increased from 10 to 15°C and remained high at 20 and 25°C. The greatest discharge occurred with apothecia at 15°C, followed by those incubated at 20, 10, and 25°C. The germination of ascospores of M. fructicola and the length of germ tubes increased as temperature increased from 7 to 15°C; however, increasing temperatures above 15°C did not increase either ascospore germination or length of germ tubes. This information may help in the development of warning systems and management strategies for brown rot blossom blight of stone fruits.

Abstract:

Germinability of dormant seeds or the capacity to germinate under particular conditions is sometimes enhanced by a diurnal alternating temperature regime relative to a constant temperature. Alternating temperature regimes vary in amplitude (difference between the minimum and maximum) and midpoint (average). The aim of this research was to test the effects of amplitude and midpoint regimes on germination of dormant leafy spurge seed from a Fargo, ND population in water and gibberellic acid (GA3). The optimal regimes for germination in both water and GA3 were 20:30 °C (16 h:8 h) and 20:35 °C (19 h:5 h), which provided amplitudes of 10 °C and 15 °C, respectively, with both conditions having a midpoint temperature of 23.3 °C. However, midpoint temperature of 22 °C to 27 °C were equally effective for germination under the 20:30 °C and 20:35 °C alternating temperature regimes. Additional alternating temperature regimes with amplitudes of 15 °C (15:30 °C and 10:25 °C), 20 °C (10:30 °C), and 25 °C (10:35 °C) generally displayed reduced germination in both water and GA3, which is likely attributable to the low initial alternating temperature (≤15 °C) component of the regime relative to the higher initial temperature of 20 °C for the optimum regimes of 20:30 °C and 20:35 °C. Under the alternating temperature regimes tested, seeds germinated in GA3 generally displayed higher germination (≥80%) compared with seeds in water (30%–50%).

Abstract:

The development, life history, reproduction, and population growth parameters of Planococcus citri Risso on coleus [Solenostemon scutellarioides (L.) Codd.] were studied at various temperatures ranging from 10 to 37?C, 70?10% RH, and photoperiod length of 16: 8 h (L: D). Females and males successfully developed into adults at from 15 to 32?C and 18 to 32?C, respectively. All first instars died at 10, 12, and 37?C. Lower temperatures (10, 12, and 15?C) caused higher egg mortality than did higher temperatures (32, 35, and 37?C). At all temperatures (except 15?C), the highest percentage of nymphal mortality was observed in the first instar. The sex ratio was female-biased between 15 and 30?C, but there was a slightly higher number of males at 32?C. The highest adult longevities of females and males were obtained at 18 and 25?C, respectively. The pre-oviposition, oviposition, and post-oviposition periods were significantly different at various temperatures. The highest fecundity was observed at 23?C. The shortest and longest oviposition periods occurred at 32 and 18?C, respectively. Maximum values of the intrinsic rate of natural increase (rm), net reproduction rate (R0), and finite rate of increase (?) and the shortest mean generation time (T) and doubling time (DT) were obtained at 25?C. Our findings showed citrus mealybug performances to be highly affected by temperature.
