Abstract:
In this paper, the effect of chemical control seed coating on the growth and the activity of protective enzymes of soybean seedlings were discussed under drought stress. Soybean seeds Suinong 10 were treated with chemical control seed coating(HK) and conventional seed coating(ND), the growth traits of plant height, plant dry weight, root dry weight, root cubage and the activity of superoxide dismutase(SOD) and peroxidase(POD) of soybean seedlings were determined. Compared with ND, Chemical control seed coating could increase plant dry weight, root dry weight and root cubage, inhibit the plant height and root shoot ratio, enhance the activity of SOD and POD under the drought stress. On the whole, Chemical control seed coating could promote plant growth rate, increase the protective enzyme activities of leaves and improve drought resistance of soybean seedlings.
