摘要: 为了提高兴安圆柏扦插生根率,探讨兴安圆柏的扦插生根机理,本试验采取不同激素处理兴安圆柏嫩枝插穗,分析嫩枝插条内水分及营养物质含量变化.结果表明,插穗生根过程中,水分、可溶性糖都是先降低后升高的过程,可溶性淀粉变化呈现升- 降的单峰曲线,可溶性蛋白变化为升- 降- 升- 降的双峰曲线.激素处理促进插穗内营养物质的转化,促进插穗生根.
英文摘要: In order to discuss the cuttings rooting mechanism and to enhance the rooting rate of Sabina davurica (Pall.) Ant, the variations of the content of the water and nutrient components in twig cuttings were analyzed during the rooting process after treated with different endogenous hormones. The results show that the water and the soluble carbohydrate increased first and decreased later during the rooting process. The content of the soluble amylum presented a single peak curve, the soluble protein was a typica...
