A new growth inhibitor, tentatively named pisumin, which increased under red light and remained at initial level or decreased when dwarf pea (Pisum sativum L. cv Progress No. 9) seedlings were transferred from red light to dark, has been isolated in the form of a colorless powder from light-exposed epicotyls of dwarf peas, and characterized partially as an aliphatic carboxylic acid (molecular weight 284) by spectrometric analyses.Exogenous pisumin inhibited the growth of epicotyl segments of dwarf peas at concentrations higher than 0.1 millimolar in the dark.
一种新的生长抑制剂，暂命名为 pisumin，在红光下增加，当矮豌豆（Pisum sativum L. cv Progress No. 9）幼苗从红光转移到黑暗中时，其水平保持在初始水平或降低，已从矮豌豆暴露在光下的上胚轴以无色粉末的形式分离出来，并通过光谱分析部分表征为脂族羧酸（分子量 284）。在黑暗中，外源性 pisumin 在高于 0.1 毫摩尔的浓度下抑制矮豌豆上胚轴段的生长。
