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。 Soaking seeds with different concentrations of choline chloride solution (200, 500, 800 and 1000 mg / L) significantly increased the content of endogenous auxin (IAA), gibberellin (GA3) and zeatin (Z) , But had little effect on abscisic acid (ABA) content; accelerating the transformation of material inside the seeds, resulting in a significant increase of soluble sugar and amino acid content in the seeds; thereby promoting seed germination and accelerating seedling growth.
