Evidence for a role of gibberellins in salicylic acid-modulated early plant responses to abiotic stress in Arabidopsis seeds.

abstract：:Survival and cold hardiness declined gradually when cold-hardened Fredrick winter wheat (Triticum aestivum L.) was maintained at -6 degrees C for several weeks. Moisture content of crown and root tissue did not change significantly during this period. Uptake of O(2) and accumulation of (86)Rb by root tissue declined a...
