以4个鲜食番茄品种为试材,测定番茄的14个农艺性状,采用相关分析、灰色关联度和多元回归分析法,研究番茄农艺性状之间的关系及与番茄产量的关系,为筛选番茄品种提供参考。结果表明:番茄产量与单株产量呈极显著正相关,相关系数为0.994 2**,产量与株高、始花节位、平均坐果数、果实纵径、平均单株结果个数和果形指数呈不显著的正相关;灰色关联度分析表明,番茄的各性状与产量间的关联度为生育期>果实横径>可溶性固形物含量>平均单株坐果数>株高>始花节位>果肉厚度>心室数量>平均单株产量>平均单株结果个数>果实纵径>茎粗>果形指数;多元线性回归表明,影响番茄产量的性状是单株产量和平均结果数;试验表明,平均结果数和单株产量是影响番茄产量的关键性状。
Four fresh tomato cultivars were used as materials to determine 14 agronomic traits of tomato. Correlation analysis, gray relational grade and multiple regression analysis were used to study the relationship between tomato agronomic traits and their relationship with tomato yield. To screen tomato Varieties provide a reference. The results showed that the yield of tomato was significantly and positively correlated with the yield per plant, the correlation coefficient was 0.994 2 **. The yield and plant height, the initial flower position, the average number of fruit set, the longitudinal diameter of fruit, the average number of fruit per plant and fruit shape There was no significant positive correlation between the index and the index of correlation. The correlations between the characters and yield of tomato were: growth period> fruit diameter> soluble solids content> average fruit number per plant> plant height> > Flesh thickness> number of ventricle> average per plant yield> number of average per plant fruit> vertical diameter of fruit> stem diameter> fruit shape index; Multiple linear regression showed that the traits affecting yield of tomato were the yield per plant and the average number of results; The results showed that the average number of results and yield per plant were the key traits affecting tomato yield.
