A Study on Cutting Propagation Technique for Male and Female Plants of Ilex Centrochinensis
摘要
Abstract
Through studying the effects of the kinds,concentrations of hormones and cutting time on rooting rate,root number and root length of cuttings.The difference in the cutting rooting of female and male plants of Ilex Centrochinensis was investigated,and the optimum conditions for the cutting propagation were obtained.The results showed that the treatment with KIBA 500 mg/L had the highest rooting rate,the rooting rates of male and female cuttings were (83.33±7.22)% and (87.50±12.50)%,significantly higher than that of the treatments with KNAA and Hormodin (P<0.05,the same below);the largest root number was KNAA 3 000 mg/L treatment,the numbers of the male and female cuttings were 26.80±4.20 and 29.40±3.70,significantly higher than those of other treatments;KIBA treatment had the best effect on promoting theIlex Centrochinensis maximum root length,the maximum root lengths of the male and female cuttings were (9.80±1.30)cm and (11.50±1.30)cm respectively.The difference in rooting ability of female and male plants of Ilex Centrochinensis was not significant.The rooting rate of male plants of Ilex Centrochinensis was slightly higher than that of female plants.In June,the rooting rate of Ilex Centrochinensis was the highest,which was significantly better than that in March,September and December.So suitable hormone for the cutting rooting of Ilex Centrochinensis was KIBA500 mg/L and the best cutting time was June.The difference in rooting ability of female and male plants of Ilex Centrochinensis was not significant.关键词
