| 中文摘要: |
| 采用酶联免疫吸附测定法测定5个蓝莓品种在花芽形成期间花芽中4种内源激素含量，研究内源激素对蓝莓花芽分化的影响，为人工调控蓝莓花芽分化奠定理论基础。研究结果表明，5个蓝莓品种在花芽形成过程中，花芽中GAs和ZR含量呈先升高后下降，再升高的变化趋势，在花芽分化初期达到最大值，之后一直保持在较低水平；IAA含量呈先下降后升高的趋势，在花芽分化中期达到最小值，之后含量迅速上升；ABA含量呈先下降后升高，再下降的趋势，在花芽分化末期达到最大值。在花芽形成过程中，5个蓝莓品种花芽中ABA/GAs比值均表现为先下降后升高；ZR/GAs和ZR/IAA的变化趋势相同，均呈先升高后下降的‘M’形变化；ABA/IAA的变化趋势与ZR/GAs相反。 |

| The content of endogenous hormones in floral bud during the bud differentiation stages in 5 blueberry cultivar by using ELISA for study the endogenous hormones was effected the floral bud differentiation. This study will provide a foundation for studying the floral bud differentiation in blueberry. These results indicated that the content of GAs and ZR in buds maintained at a low level during the floral bud differentiation stages. The content of GAs and ZR was first increased and then decreased during the floral bud formation. The change of IAA and ABA content was first decreased and then increased during the floral bud formation. The ratio of ABA/GAs indicated decreased first and then increased during the floral bud differentiation stages. The ration of ZR/GAs and ZR/IAA was similarly change trend that show ‘M’ shape. The ration of ABA/IAA was contrast to ZR/GAs and ZR/IAA. |
