| 摘 要： | 采取随机区组试验设计,通过对绿叶期盆栽石蒜进行控温处理及鳞茎内含物测定,探究温度与其鳞茎生理特性及叶片根系的关系,为石蒜的花期调控与产业化生产提供技术支持和理论依据。结果表明,适当高温(20℃、25℃)处理下,绿叶期石蒜有新根萌发,叶片枯黄;绿叶期石蒜鳞茎内可溶性蛋白含量呈先上升后下降趋势,而可溶性糖含量、超氧化物歧化酶(SOD)活性呈先下降后上升趋势。由此可见,在石蒜绿叶期适当进行高温处理可以促进石蒜根系萌发和枯叶,并且影响其鳞茎生理特性。但温度对石蒜根系萌发并无直接影响,石蒜鳞茎生理特性与根系萌发无明显关联,叶片枯黄与根系萌发存在明显关联,故温度是通过调控石蒜生长节律从而间接影响其根系萌发。
