| 摘要: |
| 研究了几种生长抑制剂对猕猴桃幼旺树成花的生物学效应和生物化学效应。生长抑制剂B9,CEPA,PP333均能有效地促进猕猴桃成花,其中PP333促花效果较B9及CEPA显著;混喷促花效果优于单喷。生长抑制剂处理后,叶片内总糖、可溶性糖、还原糖含量增加,尤其是还原糖含量显著增加,与花芽分化关系密切。根系中高含量的淀粉是花芽分化的一个突出指标。 |

| Abstract: |
| : The effect of controlling biological and biochemical characters upon young Chinese gooseberry trees was studied using growth inhibitors for controlling floral initiation. Results showed that growth inhibitors such as B9, CEPA, PP333 could effectively promote floral initiation of Chinese gooseberry, of which the effect of PP333 in floral initiation was more significant than that of B9 and CEPA. and that the effect of mixed spraying was more effective than that of single spraying. After being treated with growth inhibitors, there was an increase in the amount of total sugar, soluble sugar and reducing sugar, with a significant increase in soluble sugar in particular, being closely related to flower bud differentiation.Starch content in root system can be a protruding for flower bud differentiation. |
