Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh ...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

use poor quality resources of water and soil for food production in developing countries must be considered. therefore, three experiments were conduct in complete randomize design with four replications, to study effects of gradually application of different salinity levels (0, 10, 20, 30, 40, 50 and 60 ds.m-1) at different growth stages (planting and early seedling) and gradually application s...

crop simulation models are increasingly used in agriculture. these models help in saving time and expenses. the objective of this study was to evaluate cropsyst model in predicting development, growth and yield of wheat cultivars from golestan province. to do this, experimental data from different experiments were gathered for kohdasht, shiroodi, tajan and zagros. model performance in simulatin...

Drought is a major abiotic factor adversely affecting wheat productivity. Water deficit reduces significantly photosynthesis and hence the remobilization of stored assimilate reserves from stem becomes important sources for grain filling. We assessed ability different internodes leaf sheaths to deposit remobilize reserve assimilates as well their role in yield formation 6 winter varieties under...

In a two-year field study, we quantified the impact of post-flowering soil waterlogging on carbon assimilation and grain yield formation in wheat crops. At anthesis, cultivars YangMai 18 (YM18) YanNong 19 (YN19) were waterlogged for different durations, i.e., 0 (W0), 3 (W3), 6 (W6) 9 (W9) days using artificial structures. Changes leaf physiology, biomass production at 0, 7, 14, 21 after anthesi...

Soybean (Glycine max [L.] Merr.) ovary growth was measured from anthesis to 6 days after anthesis (DAA) to establish a timetable of biochemical events that might be useful in identifying processes that initiate abscission. Two procedures were developed to provide samples with either high or low percent pod set for ;IX93-100,' a semideterminate line having long racemes. Characteristics measured ...
