Abstract

Vegetative shoots of Arizona cypress (Cupressus arizonica Greene) were found to contain an estimated 40 to 70 mug of gibberellin-like activity per kg. Based on elution patterns of silicic acid and celite partition columns, mobilities on thin layer chromatograms and specificity of the cucumber, d-3 dwarf maize, dwarf pea, and barley half seed bioassays it was possible to determine that the tissue contained at least 5 acidic, ethyl acetate-soluble gibberellin-like substances. The major one would appear to be GA(3). In addition, GA(9), GA(4), and/or GA(7)-like compounds, and 2 unidentified gibberellin-like substances are present.

摘要

亚利桑那柏的营养芽中含有约 40 到 70 微克的赤霉素样活性物质/每千克。基于硅胶和 celite 分配柱的洗脱模式、薄层色谱上的移动性以及黄瓜、矮生玉米 d-3、矮豌豆和大麦半粒生物测定的特异性，可以确定组织中至少含有 5 种酸性、乙酸乙酯可溶的赤霉素样物质。主要的一种似乎是 GA(3)。此外，还存在 GA(9)、GA(4)和/或 GA(7)类似物以及 2 种未鉴定的赤霉素样物质。
