对蕨藻红素影响大豆下胚轴插条不定根形成的研究表明:蕨藻红素促进大豆插条不定根的形成,其最适浓度为0.5μmol·L-1,最适处理时间为2d。0.5μmol·L-1蕨藻红素处理大豆插条后,不定根诱导阶段(0～24h)的POD、CAT、IAAox活性较低;而不定根形成生长阶段(24～72h)的CAT和IAAox活性较高,POD活性低于未作处理的。试验推测蕨藻红素促进大豆插条不定根形成的生理基础可能与其影响POD、CAT和IAAox活性有关。
The study on the effect of phytoerythromycin on the adventitious root formation of soybean hypocotyl cuttings showed that phytoerythromycin promoted the formation of adventitious roots in soybean cuttings with the optimal concentration of 0.5 μmol·L-1 and the optimum treatment time was 2 days. The activities of POD, CAT and IAAox in adventitious root induction stage (0-24 h) were lower than that in 0.5 μmol·L-1 feruloplulose treatment, while the activity of CAT and IAAox in adventitious root formation stage (24-72 h) High, POD activity was lower than untreated. It was speculated that the physiological basis of the promotion of adventitious root formation by soybean phytoestrogen may be related to its effect on the activities of POD, CAT and IAAox.
