Abstract

In order to study the effects of HEAT STRESS after anthesis on source limitation of six WHEAT (Stork, Showa, Green, Star, Chamran and Fong) and two barley (Jonob and Sarasary 6) cultivars, two field experiments were conducted in delayed and optimum sowing dates. Plants in delayed sowing date experienced HEAT STRESS in after anthesis growth stage. Study of grain yield indicated that the highest grain yield was in Jonob in both conditions. Source limitation difference in experiments, cultivars in experiments and interaction between cultivars and experiments was significant in 1% probability level. Mean of source limitation in optimum and HEAT STRESS conditions was 12.5% and 25.5% respectively. Higher source limitation in late maturity cultivars such as Green and Star was related to delay in anthesis and contact of grain growth period with HEAT STRESS. In early mature cultivars such as Fong with early anthesis, grain growth period was before heat conditions, while source limitation and also grain yield and grain weight reduction was the lowest in Fong cultivar.
