| Abstract: | With sections of newly spouted shoots of Photinia glabra as explants, the influences of plant growth regulating substances on induction, proliferation and differentiation of axillary buds, growth and rooting were studied. The results showed that the medium of MS + 0.5 mgL~(-1) BA + 1.0 mgL~(-1) KT + 0.1 mgL~(-1) NAA was optimum for induction of axillary buds, with 93.3 % buds induced; The medium of MS + 1.0 mgL~(-1)BA + 0.1 mgL~(-1) NAA was optimum for bud proliferation, and the number of buds obviously proliferated with the increase of the frequency of successive transfer culture in the scope of this test; The medium of 1/2MS + 0.1 mg L~(-1) IBA and the medium of 1/2MS + 0.1 mgL~(-1) NAA were both optimum for rooting, with the rooting rate of 83.3% and 93.0% respectively. The survival rate of transplant of tube plantlets was high than 90%.Ch,3 tab.5 ref.] |
