Abstract

To study the effects of water deficit on yield and some physiologisical traits of five CORN varieties (including SC108, SC500, SC647, SC700 and SC704) at both vegetative and reproductive stages, two separate field studies were conducted in factorial based on randomized complete blocks design with five replications in Kahriz agricultural research station at years of 2004-5. Also, a second factorial green house experiment based on randomized completely design with five replications was conducted to evaluate the effect of PEG8000 on seedlings of CORN varieties. Results showed that grain yield was significantly decreased under DROUGHT STRESS. Variation percentage for RWL, RWC and chlorophyll content was 36/32, 38/91 and 38/4, respectively. Maximum and minimum grain yield under drought conditions were devoted to SC704 (7.8 ton/ha) and SC108 (6.9 ton/ha), respectively. Results of green house experiment, also, showed that PEG8000 significantly decreased radical length, plumle length and dry weight of them. In this study, hybrid SC500 was characterized the most suitable variety under DROUGHT STRESS during seedling stage.
