植物生长调节剂对百合组织培养繁殖的效应

本文报道了四种百合的生长调节物质试验结果:1.MS 附加 BA0.5mg/l、NAA0.5mg/l,有利于兰州百合鳞片分化小鳞茎;2.在 BA0.5mg/l、NAA0.1 mg/l 时,有利于兰州百合、宜昌百合和云南淡黄花百合小鳞茎的分化;3.兰州百合继代培养的最佳细胞分裂素和生长素是ZT0.1mg/l 和 IAA0.5 mg/l。一个百合小鳞茎经一年培养,可获得数百万小鳞茎,这将为百合种株的工厂化生产开辟广阔的前景。

EFFECTS OF PLANT GROWTH REGULATOR UPON LILY PROPAGATION BY TISSUE CULTURE

This paper reports the testing results of growth regulating materials of four kinds of lily:(1)MS with BA 0.5mg/l and NAA 0.5mg/l added is favour- able for squamules of Lanzhou lily to differentiate squamous bulbs;(2)BA 0.5mg/l and NAA 0.1mg/l is in favour of the squamous bulbs of Lanzhou lily,Nichang lily and Yunnan light yellow lily to differentiate;(3)ZT 0.1mg/l and IAA 0.5mg/1 are the optimum kinin and somatotrophin for lily subculture. Thus,millions of squamous bulbs of lily can be obtained from one squamous bulb of lily after one year's subculture.This will open up a new way for fac- tory production of lily.
