| 摘 要： | 研究大叶相思激素种类、浓度、处理时间以及扦插基质对大叶相思插穗生根和早期生长的影响,分析大叶相思扦插生根随时间的变化趋势,并在此基础上利用隶属函数法对各处理的生根效果进行综合评价。结果表明:3种激素以IBA处理生根效果最好,在平均根数及最长根长方面显著优于其它2种激素,并得出以黄心土为基质,用IBA 200 mg/L处理2 h为大叶相思扦插的最佳组合。10月份扦插繁殖大叶相思,插后10 d开始生根,15～20 d为生根高峰期。

| Abstract: | The effects of rooting substrates,types and concentrations of auxins and treatment time on the rooting and growth ability of Acacia auriculiformis cuttings were systematically studied,and the changes in rooting ability and growth performance of cuttings during rooting were analysed.And the general rooting effect of different treatments was evaluated based on the analysis of the subordinate function values.The results indicated that the mean number of roots and the length of the longest roots produced by cut... |
