IBA浓度、处理时间对菩提树水培扦插生根的影响

Effects of IBA concentration and processing time on hydroponics of Ficus religiosa L.

为提高菩提树(FicusreligiosaL.)的繁殖率,以菩提树半木质化插条为材料,研究了水培条件下菩提树生根情况及IBA浓度和处理时间对菩提树生根的影响。结果表明,30℃条件下,菩提树水培后10~20d可生根。留叶1片可显著提高菩提树的生根率、生根总数和根幅。IBA可以缩短生根时间,提高生根率。IBA浓度和处理时间2个因素中,IBA浓度对菩提树水培扦插生根率、生根数量等各生根指标影响显著高于处理时间,IBA浓度和处理时间的交互效应对生根率和最长根长影响显著,100mg/LIBA处理2h菩提树水培生根率最高。

In order to improve the cutting propagation efficiency of the Ficus religiosa L., using the half lignified branches of Ficus religiosa L. as the propagating material, rooting effects has been studied after treatment of different IBA concentration and processing time under hydroponic conditions. The results show that the branches can take root after hydroponic 10~20 days under 30 ℃ condition. One leaf treatment can significantly increase the rooting rate, total rooting number and rooting width of Ficus religiosa L. IBA treatment can shorten rooting time and improve rooting rate. The interaction between IBA concentration and treatment time had significant effects on rooting rate and maximum root length, the effect of IBA concentration on the rooting rate and rooting number were significant higher than the treatment time. The optimum concentration of IBA was 100 mg/L, the optimum treatment time was 2 hours.
