摘　　要：通过对巨峰、红地球、秋红、秋黑四个品种葡萄果实结构与耐压力、耐拉力关系的研究,发现葡萄浆果耐拉力大小与果柄粗细、果蒂大小以及果刷面积成正相关,与单位面积果柄和果蒂上所承受的浆果自重成负相关,耐压力强弱不仅受果肉质地影响,还与果粒大小有一定关系,与果皮厚度关系不大。果梗发育程度对葡萄耐贮性的影响远远大于果梗占果穗的比重,耐压力与耐拉力之间无明显关系。In this paper, the Relationship between attachment of stem to the berries, turgor pressure and fruit structure in four table grapes were studied of Kyoho, Red Globe,Autumn black and Autum Red grape.The result showed that attachment of stem to the berries was positvely 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. Turgor pressure not only decided by flesh character but also by the berry size,but not related to the pericarp thickness. The fruit stalk xyloidization extent effect the storability of grape more than the stalk to stem ratio.,but the attachment of stem to the berries was not related to the turgor pressure.
