摘要
应用植物激素生物试法测定了金雀花碱(cytisine)的某些植物生长调节活性,实验结果表明:金雀花碱抑制小麦芽鞘切段的伸长,但促进黑暗中(26℃)培养的离体黄瓜子叶鲜重的增加;能明显促进黑暗中(25℃)培养的离体黄瓜子叶的生根作用和根的生长;能显著提高离体黄瓜子叶中吲哚乙酸氧化酶的活性。这些现象说明,金雀花碱具有明显的植物生长调节活性。
By using bioassays,some plant growth-regulating activities of cytisine were determined. The results obtained indicated that cytisine inhibited the elongation of wheat coleoptile seg- ments but increased the fresh weight of isolated cucumber cotyledons cultured in the dark (26℃).Cytisine obviously promoted both the root formation and the root growth of isola- ted cucumber cotyledons cultured in the dark(25℃).Furthermore the IAA oxidase acti- vity in isolated cucumber cotyledons cultured in the dark was markdely stimulated by cytisine. These phenomena showed that cytisine had distinct plant growth-regulating activities
