摘要
Rice seeds were soaked with different concentration (200, 500, 800, 1000 mg/L) of choline chlo ride. The main results were as follows: Contents of endogenous hormone indole acetic acid (IAA), gibberelin (GA3), Zeatin in root and top of the rice seedling was increaed obviously, but abscisic acid (ABA) was not changed; Contents of soluble sugar and amino acid was increased; Germination of seeds and growth of seedling was promoted. Rice yield was increased by spraying choline chloride at filling stage.
