摘要

本试验研究了不同扦插位置（尖、中、基）和不同浓度的IBA（0、5、7.5和11g/L）对异叶南洋杉生根和打梢性能的影响。进行了两个析因实验。测定了扦插材料产生的叶片数、不定根数、根长和成活率。这些参数受到切割位置和激素浓度的交互作用的显著影响。插穗与11g/L IBA浓度的交互作用具有更高的根数、叶数和根长，而其他交互作用对插穗材料没有生根和打梢性能。用IBA处理插条可以适当地实现异叶A.heterophylla通过插条的营养繁殖。

The response of cutting position and auxin concentration on rooting and shooting of Araucaria heterophylla

This study was carried out to determine the effects of cutting position (tip, middle and basal) and different concentrations of IBA (IBA) (0, 5, 7.5 and 11g/L) on the rooting and shooting performance of Araucaria heterophylla. Two factorial experiments were conducted. Number of leaf, number of adventitious root and root length produced by cutting materials and the survival rates were measured. These parameters were significantly influenced by the interactive effect of cutting position and hormonal concentration. The interaction between tip cuttings and 11 g/L IBA concentration had higher root number, leaf number and root length as compared other interactions had not rooting and shooting performance on the cutting materials. Vegetative propagation of A. heterophylla through cuttings can be appropriately achieved by treating cuttings with IBA.
