- 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3 mg/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0.3 mg/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300 mg/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。
- Abstract:
- 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 Sophora japonica 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 Trichokonins.The root-shoot ratio,stem length,leaf area and so on of Sophora japonica seedling in 300 mg/L of the Trichokonins were inhibited.
