chemical composition and physicochemical properties of pumpkin seeds and fatty acids of their oil were determined. it was found that the seeds contained 41.59% oil and 25.4% protein. moisture, crude fiber, total ash, and carbohydrate contents were 5.2%, 5.34%, 2.49%, and 25.19%, respectively. the specific gravity, dynamic viscosity, and refractive index of the extracted pumpkin seed oil were 0....

in this study, the oil yield, fatty acid (fa) composition and the physicochemical and quality characteristics of salvia macrosiphon crude seed oil were determined. the main fatty acids ranked in the following order of abundance: α- linolenic acid> linoleic acid> oleic acid. the n3 /n6 fa ratio and polyunsaturated fa/ saturated fa ratio were 1.6 and 7.23, respectively. the fa composition reveale...

abstractbackground and objectives the oilseeds after cereal, the world's second largest food supply make up. environmental stress has always been one of the most important factors reducing crop yield and production are gone and counter or reduce the effects of stress as a useful strategy to increase the quality and quantity of the products has been considered. flooding conditions are said ...

Farming activity severely impacts the invertebrate food resources of farmland birds, with direct mortality to populations of above-ground arthropods thorough mechanical damage during crop harvests. In this study we assessed the effects of phenological periods, including the timing of harvest, on the composition and biomass of prey consumed by three species of aerial insectivorous birds. Common ...

gamma irradiation was used at different doses (80, 160 and 240 gy) on glycine max (l.) merrill cv. hill homogenous seeds. a single suitable m2 plant was selected and evaluated at m3 and m4 along with its parent and three other varieties as control in rcbd experiment in sari agricultural sciences and natural resources university’s experimental field. m-80-709 and m-160-3429 mutant lines were sig...

Parameters, such as oil, protein, glucosinolates, chlorophyll content and fatty acid composition, were determined using reference methods for both harvest survey samples and Canadian Canola exports. Canola harvest survey and export data were assessed to evaluate if canola harvest survey data can be extrapolated to predict the quality of the Canadian canola exports. There were some differences i...

H Harvest index (HI), ratio of seed yield to aboveground dry matter, is a very important parameter for estimating seed yield in several crop models. In this study, the importance, definition, variability and estimation methods of HI in crop models were discussed. HI estimation methods are categorized into two groups including: (i) complex methods that estimate HI from the beginning of seed gro...

The biggest challenge for jatropha breeding is to identify superior genotypes that present high seed yield and seed oil content with reduced toxicity levels. Therefore, the objective of this study was to estimate genetic parameters for three important traits (weight of 100 seed, oil seed content, and phorbol ester concentration), and to select superior genotypes to be used as progenitors in jat...
