| 摘 要： | 用细胞分裂素(Cyt)配合生长素(Aux)处理银白杨、毛白杨和山杨插穗的试验表明,增加Cyt有促进愈伤组织发育和不定根形成的作用。与Aux处理相比,Aux+Cxt处理可使愈伤组织生根时间从50d缩短至30d左右。在人工气候室条件下,山杨扦插生根率达85％。

| Abstract: | Experiments with cuttings of Populus alba, P. tomentosa and P. davidiana showed that cytokinin added to auxin resulted in stimulation of the callus development and the adventitious root formation from callus. Compared with the auxin alone, the combination of cytokinin with auxin shortened the duration needed for callus root formation from 50d to 30d. The rooting rates of P, davidiana in phytotron reached 85%. |
