Seeds of oat, coconut, soybean, sunflower, rice, millet, kidney bean, buckwheat, wheat, and corn and vegetative tissue of oat, pea, and corn were assayed for free indole-3-acetic acid (IAA), esterified IAA, and peptidyl IAA. Three conclusions were drawn: (a) all plant tissues examined contained most of their IAA as derivatives, either esterified or as a peptide; (b) the cereal grains examined contained mainly ester IAA; (c) the legume seeds examined contained mainly peptidyl IAA. Errors in analysis of free and bound IAA are discussed.
对燕麦、椰子、大豆、向日葵、水稻、小米、芸豆、荞麦、小麦和玉米的种子以及燕麦、豌豆和玉米的营养组织进行了游离吲哚-3-乙酸(IAA)、酯化 IAA 和肽基 IAA 的测定。得出三个结论:(a)所有检测的植物组织都以衍生物的形式存在大部分 IAA,无论是酯化的还是肽类的;(b)所检测的谷物主要含有酯化 IAA;(c)所检测的豆类种子主要含有肽基 IAA。讨论了分析游离和结合 IAA 时的误差。
