摘要：以红厚壳(Calophyllum inophyllum)1年生嫩枝为扦插材料,探讨不同浓度梯度的萘乙酸(NAA)、吲哚丁酸(IBA)及生根粉1号(ABT)对插穗抽叶特性和生根特性的影响,并运用隶属函数值法对各处理组合的扦插效果进行综合评价。结果表明:与对照处理相比,不同激素种类及浓度处理显著影响嫩枝插穗的抽叶率、新叶数量、新叶面积等抽叶特性指标,以及生根率、偏根率、不定根数量、不定根体积、侧根数量和侧根长度等生根特性指标,但对宿叶率影响不显著。不同激素处理下嫩枝插穗的抽叶率和生根率分别为21.7%~66.7%和43.3%~98.3%,而对照处理的抽叶率和生根率均为0。基于隶属函数值法综合分析,激素处理对扦插效果的促进作用依次为NAA>ABT>IBA。NAA处理插穗的抽叶率和生根率均值为62.1%和95.4%,分别比ABT处理增加47.5%和30.2%,比IBA处理增加62.0%和57.9%。综合分析,红厚壳嫩枝扦插的最佳处理组合为1000 mg/L NAA,其抽叶率为61.7%,生根率为95.0%。
The effects of different hormone types and concentrations,1-naphthylacetic acid(NAA),3-indolebutyric acid(IBA)and ABT-1 rooting powder(ABT)on the leaf-growing and rooting characteristics were studied on the softwood cuttings of Calophyllum inophyllum.A comprehensive evaluation was given based on membership function.The results showed compared with the control,different hormone types and concentrations significantly affected leaf sprout rate,new leaf number,new leaf area,rooting rate,partial root rate,adventitious root number,adventitious root number,lateral root number and lateral root length,but had no significant effects on the leaf retention rate.Under different hormone treatment,the leaf sprout rate and rooting rate of cuttings was 21.7%to 66.7%and 43.3%to 98.3%,respectively,while the leaf sprout rate and rooting rate of control treatment were 0.Based on the comprehensive analysis of membership function method,the promoting effect of hormones on cutting was NAA>ABT>IBA.The average leaf sprout rate and rooting rate of the cuttings treated with NAA were 62.1%and 95.4%,respectively increased by 47.5%and 30.2%compared with the treatments of ABT,and increased by 62.0%and 57.9%compared with the treatments of IBA.1000 mg/L of NAA was the best combination for the softwood cuttings of C.inophyllum,while the leaf sprout rate was 61.7%and the rooting rate was 95.0%.
