摘　　要：香椿(Toona sinensis)种芽生长到2.5、5.0、7.5 cm时,喷施0、50、100、150 mg/L的亚硒酸钠,调查其生长和品质的变化。结果表明,喷施亚硒酸钠促进了香椿种芽生长,鲜重、干重分别是对照的1.52～1.82倍、1.42～1.69倍;可溶性蛋白质、可溶性总糖、维生素C、叶绿素和类胡萝卜素含量均有增高趋势。可溶性蛋白质含量升高最多,是对照的1.38～3.09倍;香椿种芽的纤维素含量下降明显,最多下降达37.5%;香椿种芽钾和硒的含量大幅度增加,分别是对照的1.95、2.32、2.58倍和17.92、30.00、44.75倍。To test the effect of sodium selenite on the growth and quality of sprout of Chinese toona（Toona sinensis）,different concentrations of sodium selenite （0, 50, 100, 150 mg/L） were sprayed on the sprout of toona when their heights were 2.5, 5.0 and 7.5 cm, respectively. The results showed that the height,dry weight of sprout rised to 1.52-1.82 times and 1.42-1.69 times respectively; And the content of soluble protein, total sugar, chlorophyll and vitamin C increased. The greatest increase was achieved in soluble protein, 1.38-3.09 times of the control. The content of potassium and selenite in the sprout of toona increased remarkably by 1.95, 2.32, 2.58 and 17.92, 30.00, 44.75 times of the control respectively. However the level of cellulose decreased dramatically up to 37.5%.
