摘要
不同浓度（２００、５００、８００、１０００ｍｇ／Ｌ）的氯化胆碱溶液浸种明显提高了水稻根、芽中内源生长素（ＩＡＡ）、赤霉素（ＧＡ３）、玉米素（Ｚ）的含量，而对脱落酸（ＡＢＡ）含量影响甚微；加速了种子内部的物质转化，使种子中的可溶性糖、氨基酸含量显著增加；从而促进了种子萌发，加速了幼苗生长。
Rice seeds were scaded with differeat concentrati on (100,500,800,1000ug/L) of choline chloride. The main results were as follows:Contents of endogenous hormone indole acetic acid (IAA), gibberelin(GA3), cytokinin (Z) in root and top of the young rice seedling wereincreased obviously, but abscisin (ABA) was not changed; Matterconversion in internal of seeds was promoted and contents of solvablesugar and amino acid were increased; Germination of seeds and growthof seedling was promoted.
