| 摘 要： | 对11个番茄育种品系的产量构成因素(单株花序数,每花序果数,单果重)与单株产量的关系进行了通径分析.研究结果表明:2种果型番茄的单株产量的规律不同,大果型番茄(var.vulgare)的单株产量与单果重呈显著正相关;小果型番茄(var.cerasiforme)的每花序果数是单株产量最重要的因素,单果重是第2重要的因素,单株花序数对单株产量的综合效应为负值.

| Abstract: | Relationships between yield components and yield per plant of 11 tomato lines were studied by path analysis.The results showed that the law of yield per plant was different between the lines of var.vulgare and var.cerasiforme.Yield per plant of var.vulgare had significantly positive correlation with average weight per fruit.The most important factor of the yield per plant of var.cerasiforme was average number of fruits per inflorescence;and the second one was the average weight per fruit.Synthetical effect of the average number of inflorescence per plant on yield per plant was negative. |
