摘要：系统地研究了全光雾插条件下母株年龄、激素种类及其浓度对日本落叶松半木质化插穗生根的影响,并在此基础上利用隶属函数法对各处理的生根效果进行了综合评价,分别为不同年龄阶段的落叶松扦插选配出最佳激素种(?)及其浓度的处理组合,12．5、8．5 a子代林插穗经最佳组合处理后生根率分别可达78．8％、92．5％,极大地提高了较高年龄日本落叶松扦插繁殖的生根能力。三因素方差分析结果表明,母株年龄(A)、激素种类(B)和激素浓度 (C)对落叶松插穗生根率、生根量和偏根率等生根性状的影响达极显著或显著水平,同时三因素互作效应(A×B× C)反双因素互作效应(A×B、A×C、B×C)对绝大多数性状的影响也很显著。根据分年龄阶段进行的激素种类、浓度及其互作效应的比较结果,可以看出处理间生根性状的变化缺乏明显的规律性。
Effects of age, type of auxin and treatment concentration on rooting ability of Japanese larch （ Larix leptolepis） were systematically studied under mist irrigation on the open field. And general rooting effect for different treatments was evaluated and the best combinations of auxin type × concentration were selected for different ages of Japanese larch ortet. Based on subordinate function values, the results was evaluated. Once the bests combinations selected are used to treat cuttings taken from test progeny of 12.5 and 8.5 years old Japanese larch, 78.8% and 92.5% rooting percentage can be obtained, which meant that rooting ability for vegetative propagation of older Japanese larch tree was dramatically improved. Variance analysis of three factors showed rooting ability of Japanese larch was extremely or obviously influenced by age （A） of donor tree, type of auxin （B） and treatment concentration （C）. Extremely difference could be found in rooting percentage, root number per cutting, root length and rate of one-side rooting among ages or auxin treatment. There were obvious or extreme difference sparely in rooting percentage, root number per cutting and one-side rooting rate, and the in teraction effect of three factors （ A × B × C ） or interaction effects between factors （ A × B, A × C and B × C） also gave extreme influence to most of rooting characters. From results of comparing the treatment of type of auxin and concentration, and interaction effect between them for different age of the donor trees, regular changing in rooting character cannot be fund obviously in this experiment.
