The effect of several analogs of 1-triacontanol (TRIA), differing in C-chain length (16-32), the position of the hydroxyl group and the terminal functional group, were tested alone and in combination with TRIA on the growth of rice (Oryza sativa L.), maize (Zea mays L.) and tomato (Lycopersicon esculentum Mill.) seedlings. Applied alone, none of the compounds caused an increase in growth; thus, chain length (30 C) and presence and position (terminal) of the hydroxyl group appear to be specific for the growth-promoting activity of TRIA. When applied simultaneously with TRIA, all analogs inhibited the response to the latter in all three test plants, whether applied in the nutrient solution, as foliar spray or by seed soaking. 1-Octacosanol inhibited the response of rice seedlings to 2.3 x 10(-8) M TRIA at concentrations as low as 2.4 x 10(-12) M. Thus preparations of TRIA and application equipment must be free from trace amounts of other long-chain compounds if they are to be used to increase plant growth.
几种 1-三十烷醇（TRIA）类似物的效果（在 C 链长度（16-32）、羟基位置和末端官能团方面有所不同），在单独和与 TRIA 联合使用时，对水稻（Oryza sativa L.）、玉米（Zea mays L.）和番茄（Lycopersicon esculentum Mill.）幼苗的生长进行了测试。单独应用时，没有一种化合物能引起生长增加；因此，链长（30C）和羟基的存在和位置（末端）似乎是 TRIA 促进生长活性的特异性决定因素。当与 TRIA 同时应用时，所有类似物均抑制了三种测试植物对后者的反应，无论是在营养液中、叶面喷施还是种子浸泡中应用。1-二十八烷醇在低至 2.4×10（-12）M 的浓度下即可抑制水稻幼苗对 2.3×10（-8）M TRIA 的反应。因此，如果要使用 TRIA 来增加植物生长，则 TRIA 制剂和应用设备必须不含痕量的其他长链化合物。
