Abstract In C3 cereals such as wheat and barley, grain filling was traditionally explained being sustained by assimilates from concurrent leaf photosynthesis remobilization the stem. recent decades, a role for ear contributor to has emerged. This review analyzes several aspects of this topic: (i) methodological approaches estimation photosynthetic contribution filling; (ii) existence genetic va...

zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...

in order to investigate the indices of drought tolerance, correlation coefficient and path analysis at deficit irrigation and nitrogen experiment, this experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 2000-2003 for wheat at maragheh agricultural research station of dari. the treatments were included four levels of defici...

effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...

in order to study the yield and growth indix of potato under water deficit, an experiment was conducted with line-source sprinkler irrigation in khorasan razavi agricultural and natural resource research center. water deficit levels were included, at 0.75m from line-source (control), at 3.75m from line source (very mild deficit), at 6.75m from line-source (mild deficit), at 9.75m from line-sour...
