Effects of various seed priming on morphological, physiological, and biochemical traits of rice under chilling stress.

ABSTRACT:

Introduction/background

Direct-seeded rice is exceptionally vulnerable to chilling stress, especially at the seed germination and seedling growth stages in the early season of the double cropping system.

Methods

Therefore, we conducted two experiments to evaluate the role of various seed primings and their different concentrations of plant growth regulators [experiment 1-abscisic acid (ABA), gibberellin (GA₃), salicylic acid (SA), brassinolide (BR), paclobutrazol, uniconazole (UN), melatonin (MT), and jasmonic acid (JA)] and osmopriming substances (chitosan, polyethylene glycol 6000 (PEG6000), and CaCl₂) and experiment 2-GA, BR (two best), CaCl₂ (worst), and control (CK)] on rice seedlings under low temperature condition.
