Abstract

Dry matter accumulation by winter WHEAT (Tritcium aestivum L.) plant until ANTHESIS and after that is importance because yield greatly depends on translocation of dry matter at pre and post-anthesis to grain especially under DROUGHT STRESS. This study was conducted to evaluate the relationship between DROUGHT STRESS and REMOBILIZATION in four irrigated winter WHEAT cultivars. Two semi-dwarfs (Alvand, Shahryar), dwarf (MV17) and tall Tos cultivars were grown in loamy soil type in 2008 in Sanandaj Agricultural Research Station. Experimental design was randomized complete block with three replications. DROUGHT STRESS treatment include: A) Eliminate an irrigation turn at pre-anthesis (35-50 zadoks), B) Cut off irrigation period from 10 days after anhesis to maturity (after 70 scales of zadoks) and control treatment. Pre-anthesis DROUGHT STRESS treatment with 63.3 g/m2 has been most REMOBILIZATION. post-anthesis and control treatments had been non-signification difference. High amount of REMOBILIZATION was in Shahryar at pre-anhesis DROUGHT STRESS treatment (80 g/m2). Shahryar cultivar had been by 52.6% REMOBILIZATION efficiency (RE). But most RE after ANTHESIS DROUGHT STRESS was in Tos (34.3%). High of culms at pre-anthesis DROUGHT STRESS had been significantly difference with post-anthesis and control. The result showed that, REMOBILIZATION of dry matter at pre-anthesis DROUGHT STRESS treatment (35-50 zadoks) was more than post-anthesis DROUGHT STRESS and control treatment. Pre-anthesis DROUGHT STRESS in semi-dwarf and post-anthesis DROUGHT STRESS in tall cultivars probably increase REMOBILIZATION of dry matter and its efficiency.
