Effects of tomato nutritional traits on its fruit yield

Abstract：Three kinds of tomatoes varieties was conducted to investigate effects of tomato nutritional traits, including relative growth rate, specific leaf area, leaf dry mass content, plant height and root mass per unit leaf area, on its fruit yields by a pot experiment. The results of this study showed that three kinds of tomatoes significantly differed in their measured nutritional traits. General linear correlation analysis indicated that fruit yields was significantly correlated with relative growth rate and specific leaf area, respectively, but not correlated with plant height, and negatively correlated with leaf dry mass content and root mass per unit leaf area. The stepwise multiple regression further analysis showed that the fruit yields was only positively correlated with relative growth rate and specific leaf area. This study suggested that it was better to consider multiple growth characteristics for determining the relationship between tomato functional traits and fruit yields.
