of Helianthus tuberosus explants grown in vitro . These activities are often similar or sometimes higher than those of IAA. By contrast, the 1,2-benz iso thiazole derivatives having a side chain with an odd number of carbon atoms (-3-yl-carboxylic and propionic acids, amides, ethyl esters and nitriles) are inactive or show a far lower activity.
摘要 1,2-苯异噻唑-3-基-乙酸和-3-基-丁酸及其乙酯、酰胺和腈在豌豆茎裂试验中通常具有活性,可诱导长度和鲜重的增加。豌豆节间,抑制豌豆根的发育,并且,除了一些例外(1,2-苄异噻唑-3-基-丁酰胺和腈),诱导豌豆节段产生乙烯。此外,它们刺激细胞增殖并提高体外生长的向日葵外植体的水合作用程度。这些活动通常与 IAA 的活动相似或有时更高。相比之下,具有奇数个碳原子侧链的 1,2-苯并异噻唑衍生物(-3-基-羧酸和丙酸、酰胺、乙酯和腈)是无活性的或表现出低得多的活性。
