Improvement of Germination Characteristics and Enhancement of Antioxidant Enzymes Activity of Safflower (Carthamus Tinctorius L.) Aged Seeds by Used of Gibberellin

Abstract

ABSTRACT. Seed priming is one of the methods that can be taken to counteract the adverse effects of abiotic stress, also Seed priming treatments have been used to reduce the damage of aging and invigorate their performance in many crops. Objective of this study was to evaluation the effect of gibberellin on germination characteristics and antioxidant enzymes of safflower seeds after aging. Experimental design was a factorial one with complete randomized design with three replications. The first factor was pri…
