An experiment as a split plot based on randomized complete block design with three at the Agricultural Research Station of Ardabil was carried out. The main plots were four levels of drought stress (a1: irrigation after 70 as control, a2: 100, a3: 130 and a4: 160 mm evaporation from pan class A), and the sub-plots were four levels of foliar ascorbic acid (b1: control, b2:150, b3: 200 and b4: 250 ppm). The results of the study revealed that drought stress significantly decreased the length of ear, number of grains per ear, number of grains row per ear, number of grain in row, dry weights of covers ear, 300 seed weight and grain yield. The foliar application of ascorbic acid had positive effects on decreasing drought stress on all traits in this study. In general, the results indicate that the usage of ascorbic acid decreased the harmful effects of drought stress and significantly increased tolerance to drought stress in traits of corn plant.}, keywords = {Drought Stress,Dry weight,Ascorbic acid,Sweet corn}, url = {https://breeding.tabrizu.ac.ir/article_12492.html}, eprint = {https://breeding.tabrizu.ac.ir/article_12492_e63d01378dccaf72aae1bf5aa110ee24.pdf} }
