Heat stress during flowering is a critical limitation for summer maize production. However, the incidence of heat varies with years and locations, it poses great risk to successful reproduction kernel setting. Therefore, essential provide sound quantification occurrence in relation growth development. Here, we analyzed characteristics based on climate data over 60 Huaibei Plain, China. The effe...

Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...

More frequent and more intense heat waves greater drought stress will occur in the future climate environment. Short-term extreme often simultaneously after winter wheat anthesis, which has become major constraint threatening yield. In this study, short-term heat, their combination were applied to plants all restored outdoor normal temperature full watering treatment. The aim of current study w...

terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...

in order to investigate the effects of drought stress and nitrogen fertilizer on photosynthesis rate and some physiological characteristics in two barley cultivars, a pot experiment was conducted using a randomized complete block design as a factorial experiment with three factors including water stress, nitrogen fertilizer and barley cultivars in three replications. irrigation treatments condu...

wheat grain yield is adversely affected by post-anthesis drought stress conditions in most wheat growing areas of iran. to evaluate the effect of late drought stress on wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of collage of agriculture, shiraz university during 2009-2010 growing season. ir...

High temperature stress during grain filling substantially decreases wheat productivity; thus, to ensure food security, heat tolerance in must be developed. It remains unclear whether exogenous salicylic acid (SA) can induce high temperatures at the grain-filling stage. In this study, a two-year pot culture experiment using cultivar ‘Yangmai 18’ was conducted from 2018 2020. The plants were pre...

Climate change threatens to impact wheat productivity, quality and global food security. Maintaining crop productivity under abiotic stresses such as high temperature is therefore imperative managing the nutritional needs of a growing population. The article covers current knowledge on post-anthesis heat grain yield crops. objectives were review (1) effect stress events (above 30.0 °C) yield, (...

Glume-unclosing after anthesis is a widespread phenomenon in hybrid rice and also a maternal hereditary trait. The character of Glume-unclosing in rice male sterile lines also seriously influences germination rate and the commercial quality of hybrid rice seeds. We validated that the type of glume-unclosing after anthesis in the elite rice thermo-sensitive genic male sterile (TGMS) line RGD-7S ...
