Abstract:
The effects of exogenous hormone ABA and ETH spraying on soybean physiology and leaf epidermal wax morphology were studied by artificial water control, which laid the foundation for later study on physiological and molecular mechanisms of drought resistance in soybean. The results showed that ABA and ETH were treated with 14 d, the relative water content and chlorophyll content of leaves were not significantly different among the treatments, the water loss rate of ABA and ETH treated leaves were lower than CK after 80 min of water loss. On 28d, the relative water content of hedehydrated leaves in vitro ABA, ETH were significantly higher than that of 14 d, the relative leaf water content of ABA was significantly between ETH and CK treatment, there was no significant difference between ETH and CK; the chlorophyll content was lower than the content of 14 d, the leaf chlorophyll content of ABA treatment and ETH treatment were significant difference, ABA treatment and CK treatment had no significant difference; the leaf water loss rate of each treatment was progressively increased, after 60 min the rate of ABA and ETH tended to be the same. The ABA, ETH and CK treatments of 28 d, scanning electron microscope observation of soybean leaf epidermis wax was stick bar with no significant difference in number, and stem epidermis wax number of ETH treatment was significantly less than ABA and CK treatment, presented sheet structure.
