摘　　要：为研究葡萄裂果与品种及水分的关系,以‘红地球’‘魏可’‘意大利’‘玫瑰香’等4个品种为试材,在浸果0~60 h的条件下观察葡萄重量变化及裂果情况,结果显示:‘意大利’的吸水率较大为7.89%,‘红地球’‘魏可’‘玫瑰香’吸水率在2.50%~3.24%,其中‘红地球’‘魏可’‘意大利’吸水率与时间呈先增加后降低趋势,‘玫瑰香’浸果前期吸水率较快,后期吸水率随时间变化不大。‘红地球’(50%)‘意大利’(50%)的裂果率显著高于‘魏可’(25%)‘玫瑰香’(25%),且浸果前期‘红地球’裂果率增长速度最快。‘红地球’‘魏可’‘意大利’‘玫瑰香’的吸水率与裂果率均表现为极显著正相关,其中‘红地球’裂果率随吸水率增长速度最快。In order to study the relationship between grape cracking fruit and variety and water content,four varieties including‘Red Globe’‘Wink’‘Italia’and‘Muscat Hamburg’were used as materials to observe the weight change and fruit cracking of the grapes under the condition of 0~60 h immersion.The results showed that the water absorption rate of‘Italia’was 7.89%,and the water absorption rates of‘Red Globe’‘Wink’and‘Muscat Hamburg’were between 2.50% and 3.24%;at the same time the water absorption rates and time of‘Red Globe’‘Wink’and‘Italia’increased first and then decreased.The water absorption rate of‘Muscat Hamburg’fruit in the early stage was higher,and the water absorption rate did not change much with time.‘Red Globe’(50%)and‘Italia’(50%)had significantly higher rates of fruit cracking than‘Wink’(25%)and‘Muscat Hamburg’(25%)and the growth rate of‘Red Globe’cracking rate in the early stage was the highest.The water absorption rate and fruit cracking rate of‘Red Globe’‘Wink’‘Italia’and‘Muscat Hamburg’were all significantly positively correlated,and the‘Red Globe’cracking rate increased the fastest with the growth of water absorption rate.
