摘要
采用NAA、GA和IAA为试验因素,探讨激素处理对竹节树插穗各生长性状的影响,采用3个水平进行处理(包括空白对照),采用L9(34)正交试验设计进行试验。结果表明,各处理组合对根长和根粗影响差异不显著,但有促进作用,对存活率和生根率影响显著。NAA对存活率和生根率有极显著影响,IAA对生根率有显著影响,但对存活率影响不显著,理论最优组合为A3B2C3,即NAA,1.00 g/L、GA,0.5 g/L和IAA,0.8 g/L对竹节树插穗生长影响最显著。
Taking NAA,GA and IAA as experimental factors,the paper discussed the hormone treatment on growth traits of each Carallia brachiatacuttings. Through three levels processing（ including blank control） and L9（ 3^4） orthogonal design test,the results showed that the effects of treatment combination on root length and root diameter were not significant,but promote the role,the effects on survival and rooting rate were significantly. NAA had significant impacts on survival and rooting rate,IAA also had a significant effect on rooting rate,but not significant effect on survival rate. The optimal combination of theory was A3B2C3,namely NAA,1. 00 g /L、GA,0. 5 g /L 和 IAA,0. 8 g /L,which had significant impact on Carallia brachiata spike growth.
