Title: Research on Cutting Rooting Ability of Alnus ferdinandi-coburgii
Abstract: Studied on effect on rooting efficiency of different individuals by choosing mother trees of different ages and individuals,the effect of different cutting mediums,hormone treatments and positions on rooting efficiency of Alnus ferdinandi-coburgi were studied.The results showed that the difference of rooting ability among different seedlings individuals in the same age was significant.The rooting complexions of sprout cuttings was the best,the rooting rate and quality were both higher than that of seedlings,besides the difference was not significant.Rooting rate order was:current year(31.45%)3 years old(10.11%)5 years old(6.30%).The cutting rate(47.37%) and rooting index(5.75) of basal cutting were the best,the differences of rooting rate and rooting quality and complexions were not significant.The effect on cutting ability of different hormones treatment was significant.The effect of low concentration of soaking for 3 h was generally higher than treatment with high concentrations of 1 min.The rooting numbers were the best 5.26 under the treatment 100 mg/L IBA 3 h,rooting property was the best,the rooting index was 45.148.The rooting rate(52.08%) and root length(9.3 cm) were the best by soaking for three hours under water.The rooting ability showed the best by using vermiculite,in which the rooting rate was 30.67%,rooting index was the highest 8.661.among mixing matrix,the best was peat∶perlite∶red=1∶2∶1,with the highest rooting rate of 26.67%.
