摘要
试验研究了烯效唑浸种对谷子幼苗生长及其生理指标的影响。结果表明：用1～20mg／L烯效唑溶液处理后，谷子幼苗苗高明显受到抑制；地上、地下部分干物质积累增加；根冠比、叶绿素含量、可溶性糖含量和可溶性蛋白含量增加，同时POD和SOD活性提高，MDA含量和外渗电导率下降。说明烯效唑浸种有助于谷子壮苗和增强抗逆性，5mg／L烯效唑浸种效果最明显。
The effects of seed soaked in uniconazole solution on the growth and some physiological indexes of Millet seed were studied. The results were as follows： after seeds were soaked in uniconazole solution of different concentrations（1-20mg/L）, the shoot height of seedling was restrained distinctly, shoot dry weight and root dry weight of millet seedling, the root--shoot ratio, chlorophyll content, soluble sugars content, soluble proteins content, SOD and POD activities of millet seedling were all increased, MDA content and electric conductivity were decreased. It followed that uniconazole is beneficial to grow strong seedlings and increase stress--resistance. The optimum concentration of seeds soaked in uniconazole solution was 5mg/L.
