摘要
文章采用了三因素三水平L9(33)正交试验设计,研究了不同生长调节剂对云杉扦插育苗生根率的影响。正交试验结果表明,生长调节剂种类是影响云杉扦插生根率的最主要因素,不同生长调节剂作用下云杉的生根率差异达到了显著差异水平。云杉达到最佳生根率的生长调节剂使用条件是:使用IBA生长调节剂,在浓度为0.1 g/L时浸泡1.5 h。
The effect of different kinds hormone on rooting capability of cutting propagation of Picea asperata are studied by the L9(3^3) orthogonal design. The results showed that there was significant difference between different kinds of growth regulators for rooting capability of cutting propagation, and the optimum condition for rooting capability of cutting propagation of Picea asperata was soaking 0.1g/L IBA hormone for 1.5h.
