试验表明,BA对山杨叶柄分化芽的增殖和生长影响均显著;NAA对芽的增殖影响不显著,而对生长影响显著。在WPM基本培养基附加0.5ppm BA和0.05ppm NAA的试验条件下,PP_(333)对芽的增殖及高生长均有影响,且高生长影响大于增殖的影响。最佳增殖培养基为WPM+BA_(1.0)+NAA_(0.05)+PP_(333 1.0);高生长最佳培养基为WPM+BA_(0.5)+NAA_(0.1)+PP_(333 0.5)。
The results showed that BA had significant effects on the proliferation and growth of buds of asparagus petiole. NAA had no significant effect on bud proliferation but had significant effects on the growth of shoots. Under the conditions of WPM minimal medium supplemented with 0.5ppm BA and 0.05ppm NAA, the effect of PP_ (333) on proliferation and height growth of buds was affected, and the effect of high growth was greater than that of proliferation. The optimal medium for growth was WPM + BA_ (1.0) + NAA_ (0.05) + PP_ (333 1.0) and the best medium for growth was WPM + BA_ (0.5) + NAA_ (0.1) + PP_ (333.5).
