Abstract

Hydroxycinnamoyl putrescines promote the cell multiplication of leaf discs of a tobacco mutant, RMB7, cultivatedin vitro on the Murashige and Skoog medium. This mutant never accumulates these molecules during its development and does not enter in floweirng. Maximal effect is obtained at 2.5·10(-4)M. The same molecules inhibit bud formation ofNicotiana tabacum var. Xanthi nc, at 5·10(-5) M but promote callus formation. From 10(-4) M to 5·10(-3) M they strongly inhibit cell multiplication and bud formation without toxic effect. Their possible role in plant metabolism is discussed.

摘要

羟基肉桂酰腐胺促进在 Murashige 和 Skoog 培养基上离体培养的烟草突变体 RMB7 的叶片圆盘的细胞增殖。该突变体在其发育过程中从不积累这些分子，也不会进入开花期。在 2.5·10(-4)M 时可获得最大效果。相同的分子在 5·10(-5)M 时抑制黄花烟草变种 Xanthi nc 的芽形成，但促进愈伤组织形成。从 10(-4)M 到 5·10(-3)M，它们强烈抑制细胞增殖和芽形成，而没有毒性作用。讨论了它们在植物代谢中的可能作用。
