不同处理对七叶莲嫩枝扦插生根影响的研究

Influence of Exogenous Hormone on Rooting of Shoot Cuttings of Schefflera venulosa

  • 摘要: 以1年生七叶莲嫩枝为插穗,在云南省普洱市林科所苗圃的塑料小拱棚内,采用插穗长度、外源激素种类和浓度3因素3水平L9(33)正交试验,探讨不同插穗长度和外源激素对七叶莲嫩枝生根率的影响。结果表明:不同穗条长度对七叶莲生根率、平均根长和最大根长影响显著;激素种类对七叶莲生根影响较显著,七叶莲扦插适宜的激素为IBA;激素浓度对七叶莲生根影响差异不显著。生根率、生根数量、平均根长的最优组合为插穗长10cm、300mg/L吲哚丁酸,生根率达到893%,具有较好的生根效果,可在生产中推广使用。

     

    Abstract: Taken annual Schefflera venulosa shoots as cuttings, the L9 (34) orthogonal test was carried out in the nursery of Forestry Research Institute of Pu′er Municipality. The cutting experiment has been done with 3 factors and 3 levels of different cutting length, exogenous hormones, hormone concentrations to find out the influence of exogenous hormones on rooting rate of Schefflera venulosa. The results showed that different cutting lengths had significant effects on the rooting rate, average root length and maximum root length of Schefflera venulosa. The effect of different exogenous hormones on the rooting of Schefflera venulosa was significant, the suitable exogenous hormones for the cuttage of Schefflera venulosa was IBA. The effect of exogenous hormones concentration on the rooting of Schefflera venulosa was not significant. The best combination of rooting rate, number and average root length was 10cm cutting length, 300mg/L IBA, and 893% rooting rate which could be used in the production.
