摘　　要：以酿酒品种赤霞珠果实为试材,研究了延迟采收对赤霞珠果实细胞质膜的影响。结果表明,延迟采收后,葡萄果实细胞质膜透性及丙二醛、脯氨酸和过氧化氢的含量均有所提高。其中,细胞质膜透性增大37.2%,丙二醛含量和脯氨酸含量分别增加35.1%,405.7%,过氧化氢含量增加41.5%。方差分析表明,细胞质膜透性从9月21日-10月21日各个时期差异不显著;脯氨酸含量从10月1-21日各时期差异达显著水平;丙二醛和过氧化氢含量在各时期差异均不显著。In this paper,the wine grape berry（Vitis vinifera L.cv.Cabernet Sauvignon） were used as materials,and the effect of harvesting prolongation on the plasma membrane permeability was studied.The results showed that both plasma membrane permeability and the concentration of malondialdehyde,proline and hydrogen peroxide in the grape berry were increased.The plasma membrane permeability,the concentration of malondialdehyde（MDA）,proline and hydrogen peroxide（H2O2） were increased by 37.2%,35.1%,405.7% and 41.5%.But there was no significant difference in plasma membrane permeability from Sep.21st to Oct.21st,and in the concentration of MDA and H2O2 in the whole period,and there was significant difference in the concentration of proline from Oct 1st to Oct 21st.
