摘要(Abstract):
本试验以四川本土漆树根段为材料,探讨采用不同生根剂时,树龄、根粗度、生根剂浓度、处理时间对漆树根繁生根率的影响,通过综合分析筛选出漆树根繁育苗最适组合。结果表明:生根剂、树龄、生根剂浓度对漆树根繁的成活率有极显著影响,浸泡时间和根粗度对成活率影响不显著;在生根剂与各因素的交互作用中,生根剂×浸泡时间、生根剂×树龄对成活率有极显著影响,生根剂×根粗度对成活率有显著影响,生根剂×生根剂浓度对成活率的影响不显著。本研究筛选的最适合四川南部地区漆树根繁育苗的因素组合是:生根剂GGR、树龄1年、根粗度0.3~0.5 cm、生根剂浓度100 mg·L~(-1)、浸泡时间10 min。
In this experiment, Sichuan local lacquer tree root sections were used as the material, and the effects of the tree age, root diameter, concentration of rooting agent and treatment time on the rooting rate of lacquer were discussed.Through comprehensive analysis, the most suitable combination of lacquer root propagation seedlings was selected. The results showed that rooting agent, tree age and rooting agent concentration had significant effects on the survival rate of lacquer tree root propagation, while soaking time and root diameter had no significant effect on the survival rate.Among the interaction between rooting agent and various factors, rooting agent × soaking time, rooting agent × tree age had very extremely significant effects on the survival rate, rooting agent × root diameter had significant effect on the survival rate, and rooting agent ×rooting agent concentration had no significant effect on the survival rate. The most suitable combination of factors selected in this study for lacquer tree root breeding seedlings in southern Sichuan was:rooting agent GGR, tree age of one year, root diameter of 0.3–0.5 cm, rooting agent concentration of 100 mg·L~(-1) and soaking time of 10 min.
