摘要
以国槐幼苗为试材,采用灌根的方法,研究比较了不同浓度康宁霉素处理对国槐幼苗生长及生理的影响。结果表明:康宁霉素灌根处理对国槐幼苗的株高、根冠比及各物质含量均有促进作用,在康宁霉素浓度为3mg/L时对国槐幼苗的根冠比促进效果最好,在康宁霉素浓度为0.3mg/L时对国槐幼苗的株高及叶绿素总含量、可溶性蛋白质含量、可溶性糖含量等的促进效果较为显著;在康宁霉素浓度为300mg/L时对国槐幼苗的根冠比、株高、叶面积等有一定的抑制作用。
Taking Sophora japonica seedling as material, using the method of filling-root injection, the influence of different concentration of Trichokonins on Sophora japonica seedlings growth and physiological were studied and compared. The results showed that it had promoting effect to the root-shoot ratio,stem length and material content in the Sophorajaponica seedlings by the Trichokonins filling-root, this could effectively improve stem length, the soluble protein,soluble sugar, chlorophyll content of the Sophora japonica seedlings in 0. 3 mg/L of the Trichokonins, and increased. The root-shoot ratio of Sophora japonica seedling in 3 mg/L of the Triehokonins. The root-shoot ratio,stem length,leaf area and so on of Sophora japonica seedling in 300 mg/L of the Trichokonins were inhibited.
