بررسی اثر تنش خشکی بر روی میزان آنزیم های کاتالاز، پراکسیداز و پلی فنل اکسیداز در تعدادی از هیبریدهای ذرت در مغان

Identification of physiologic parameters related whit droughts tolerance has important role in selecting tolerant verieties. In order to study the effect of drought stress on physiologic traits in corn, an experiment was conducted as split–plot using randomized complete block design with three replications in research station of Moghan collage of agriculture and natural resources, university of Moghaghegh Ardabil in 2013. The main plot consists of three irrigation regimes, and 7 corn hybrids were considered as subplots. Analysis of variance showed significant differences among Irrigation regimes, hybrids and Irrigations×hybrid interactions for all studied parameters. In drought conditions, the amount of CAT, POX and PPO enzymes
were increased. The highest amount of catalase was observed in SC302, and hybrid SC400 had the highest
amount of POX and PPO enzymes.
