| 摘要: |
| 通过对巨峰、红地球、秋红、秋黑4个葡萄品种果实结构的比较，探讨了葡萄果实耐贮性的生物学原理。结果表明，葡萄果柄耐拉力大小与果柄、果蒂截面积以及果刷大小和维管束数量呈正相关，与单位面积果柄和果蒂上所承受的浆果自重呈负相关，而与果皮厚度、果粒质量无明显关系；葡萄浆果耐压力强弱不仅受果肉质地的影响，还与果粒细胞大小、分布、排列有一定关系，但与果皮厚度、果粒质量关系不大；葡萄浆果耐压力和果柄耐拉力之间无明显关系。 |

| The relationship between fruit structure with pressure and pulling force of berry of grapes |
|
|
| Abstract: |
| In this paper ,the relationship between pulling force of fruit stalk ,maximum pressure to the berries and fruit structure in four table grapes were studied of Kyoho,Red Globe,Autumn black and Autumn Red grape. The result showed that pulling force of fruit stalk to the berries was positively correlated to the diameter of fruit stalk ,diameter of the fruit stalk end and total fruit stalk binding area but negatively to the total berry weight per unit area of stalk and stalk binding area. Maximum pressure of flesh was not only decided by flesh character but also by the berry size,but not related to the pericarp thickness, maximum pressure of flesh was not related tO pulling force of fruit stalk, |
| Key words: grape fruit structure maximum pressure of flesh pulling force of fruit stalk |
