| 摘 要： | 采用正交设计，研究了不同浓度氨基酸和赤霉素混合喷施对三叶赤楠枝条、叶片生长的影响。结果表明：三叶赤楠的生长曲线呈现双峰状，春秋季各有一生长高峰。氨基酸和赤霉素两者间交互作用显著，对三叶赤楠枝条和叶片生长均有一定的促进作用。但氨基酸对于三叶赤楠生长的促进作用有限，在观察到的生长差异中，绝大部分是由赤霉素浓度差异造成的。对于枝条及叶片生长来说，100 mg·L-1的赤霉素浓度比较合适。新梢长、新梢分枝数及叶面积受混合喷施影响较大，不同处理间差异显著或极显著，而成熟枝条及叶片厚度受其影响较小，差异不显著。经主成分分析发现新梢月平均生长量和分枝数可作为快速评价混合喷施效果的描述指标；而叶片厚度和叶面积，即第二主成分可作为潜在评价氨基酸和赤霉素混合喷施长期效果的描述指标。在生产中可以以新梢长度、生长量和分枝数作为评价氨基酸与赤霉素喷施效果的快速指标。

| Abstract: | An orthogonal design was used to assess the influence of gibberellin and amino acid on branch and leaf growth of Syzygium grijsii.The results showed: the growth curve of S.grijsii was a double-peak type,there were two growth peaks in spring and autumn,respectively.There was significant interaction between gibberellin and amino acid,which had promotion effects on the branch and leaf growth of S.grijsii.Most observed variance of growth was obviously affected by the concentration of gibberellin acid whereas am... |
