The Influence of Different Seed Dressing Treatments on Wheat Seedlings Growth under Water Stress Conditions

Aiming at the seeding date drought problem of wheat on the loess plateau region, this article studied the compounding of 3 chemical agents, i.e. CaCI2, gibberellins (GA) and composite rare earth at different concentrations and the difference of seed dressed wheat in its germination rate, germination vigor and seedling shape under indoor simulation water stress conditions. The composite rare earth with the compounding combination of 1.5% CaCI2+0.1% was selected. Using this combination in seed dressing can raise wheat seedling's germination rate and germination vigor while it helps the vigorous growth in the seedling stage.
