Abstract

In order to evaluate the effects of WATER DEFICIT on yield and some physiological traits of five CORN varieties (SC108, SC500, SC647, SC700 and SC704) at both vegetative and reproductive stages, two separate field experiments were conducted based on Randomized Complete Blocks design with five replications in Kahriz agricultural research station at years of 2004-5 under normal and WATER DEFICIT conditions with 75 and 150mm evaporation class A pan, respectively. Also, a second 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. Maximum variation percentage for Brix Coefficient, Electrical Conductivity and Potassium Accumulation was 49.48, 51.31 and 106.51, respectively. Maximum and minimum grain yield under WATER DEFICIT conditions were devoted to SC704 (305.54g/m2) and SC108 (143.01g/m2), respectively. Results of green house experiment, also, showed that PEG8000 significantly decreased radical and plumule lengths and dry weights of them. In this study, hybrid SC500 due to more radical and plumule dry weights was characterized the most suitable variety under WATER DEFICIT during seedling stage.
