摘　　要：对85份番茄和樱桃番茄自交系萼片形态进行了观察,发现从开花到果实红熟,萼片与果实纵轴夹角从小于90°逐渐变化到大于180°,红熟期萼片呈现基平、上翘、直立和上卷4种形态。基平,萼片伸展方向与果实纵轴夹角在90°～100°范围内;上翘,萼片伸展方向与果实纵轴夹角在101°～170°范围内;直立,萼片伸展方向与果实纵轴夹角在171°～180°范围内;上卷,萼片伸展方向与果实纵轴夹角大于180°,且萼片向内卷曲。其中基平型占4.71%,上翘型占1.18%,直立型占17.65%,上卷型占76.47%。Sepal shape of 85 materials,including inbred lines of tomato(Lycopersicon esculentum Mill.)and cherry tomato,were observed.The results show that there is a gradual change of sepal shape from less than 90 degrees to over 180 degrees from flowering to fruit maturity.The sepal shape can be classified into spread,up-spread,upright and scroll 4 types at red ripe stage.The following is the angle between stretching direction of sepal and the fruit vertical axis.Spread is in the range of 90-100 degrees,up-spread is 101-170 degrees,upright is 171-180 degrees,scroll means the angle is more than 180 degrees,and it is entad curling.The ratios are 4.71 %,1.18 %,17.65 % and 76.47 %,respectively.
