Abstract
This study investigates the physiological changes of two varieties wheat (Triticum aestivum L.) seedlings namely LX77 and JM22 by spraying different concentrations of epibrassinolide (EBR) under Cd2+ stress using a hydroculture. Results showed that after foliar application of different concentrations of EBR, seedling growth properties, chlorophyll contents, root vigor, osmotic regulators, malondialdehyde (MDA) and H2O2 contents, relative conductivity, antioxidant enzyme activities were changed in both LX77 and JM22, and the optimal exogenous EBR concentration is 0.01 or 0.1 mg·L− 1.
