Abstract

In order to determine the best method of seed hardening, an experiment was carried out in greenhouse stages in the format of split – split plot design. First factor including four levels of drought stress (100% FC, 75% FC, 50%FC, 25%FC), and second factor including 4 genus (Vicia villosa, Onobrychis sativa, Trigonella foenum and Lens culinaris), and third factor including resistance method in five levels (CuSO4, ZnSO4, B, control, alternative watering). Four physiological characteristics root and shoot lengths and root and shoot fresh weights were evaluated. Treatments showed significant differences for most of the traits. Treatment of alternative watering and drying in Trigonella had the most effect. Comparison of treatments showed that Onobrychis, Vicia, Trigonella and Lens demonstrated better growth under treatments and also CuSo4, B and ZnSo4 has effected respectively in induction of gradual consistency of seeds to drought stress.
