摘　　要：采用外源激素单独和复合渗透处理,研究在低温层积条件下对百合小鳞茎活力的影响,结果表明:外源激素处理能显著提高小鳞茎的活力表达,且含有GA3成分的复合处理较其他处理效果明显。采取IAA 100 mg/L+6-BA 100 mg/L+GA350 mg/L对百合试管小鳞茎进行渗调处理,同时在2℃条件下层积时间超过120 d,能极大改善百合小鳞茎的发芽率、芽干重和活力表达,促进百合试管小鳞茎的田间应用。Effect of low temperature stratification on the viability of lily bulb in vitro were studied by simple or compound osmotic treatment of the exogenous hormone,the results showed that exogenous hormone treatment could significantly improve the activity expression of bulblets,and the compound treatment containing GA3 component had more obvious effect than the other treatment.In production,taking the osmotic treatment of IAA 100 mg/L ＋ 6-BA 100 mg/L ＋ GA3 50 mg/L on tube lily bulb with the deposition time exceeds 120 d in the condition of 2℃,could greatly improve the germination rate,shoot dry weight and expression activity of lily bulb,and promote its field application.
