Pea (Pisum sativum L.) mutant near-isogenic lines (RRrbrb, rrRbRb, rrrbrb) with lower starch but higher lipid contents, brought about by lesions in the starch biosynthetic pathway, had seed moisture sorption isotherms displaced below that of the wild type (RRRbRb). The negative logarithmic relationship between seed longevity and seed storage moisture content (%, f.wt basis), determined in herme...

kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

Thermodynamic models and Soft-computing method of Neural Network (NN) were used for computation of sesame seed dehydration energy (heat and entropy). The NN method for prediction of the Equilibrium Moisture Content (EMC) of sesame seed was utilized. The heat of sorption of sesame seed is predicted by a mathematical model. After well training of the NN model, predictive power of the model was fo...

Seeds of carrot, groundnut, lettuce, oilseed rape and onion were stored hermetically in laminated aluminium foil packets in four environments (dry or ultra-dry moisture contents combined factorially with temperatures of 20°C or -20°C), replicated at several sites. After ten years’ hermetic storage, seed moisture content, equilibrium relative humidity, viability (assessed by ability to germinate...

sesame is one of the most important oil crops in iran. high oil seed content makes it difficult to store for a long period of time. this study was conducted in 2012 to evaluate possible physiological and biochemical changes in seed under different storage conditions. various seed moisture content (5, 9, 13, and 17%) were evaluated under five temperatures (5, 15, 25, 35, 45) for six month. germi...

in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...

an aerobic, meophilic and lipolitic bacillus.sp bacterium (lipase activity 40 u/ml) was isolated from the olive extract. this isolate was identified based on morphological and biochemical characterization and 16s rrna gene sequence. effect of the solid substrate (pomegranate seed ground, grape seed ground and coriander seed ground as a solid substrate), the substrate particle size, moisture con...
