瓜位叶性状对西瓜小果型自交系材料单瓜重的影响

Effects of Watermelon Position Leaf Character on Weight of Small-fruit Watermelon

在鄂尔多斯地区对16份小果型西瓜材料进行田间试验,比较了各材料在单瓜重及瓜位叶叶色、叶重、叶面积方面的差异,分析了瓜位叶性状对西瓜材料单瓜重的影响。结果表明:单瓜重最高的是西瓜材料190511,瓜位叶的叶色、叶重、叶面积均与单瓜重呈显著正相关。瓜位叶叶面积对西瓜自交系材料单瓜重的大小发挥了最主要的作用,瓜位叶叶色对西瓜自交系材料的单瓜重发挥了最直接的作用。

Field experiment on 16 small-fruit watermelon was performed in Ordos area,the difference among color,weight and area of watermelon leaf were compared,the effect of leaf position character on the fruit weight of watermelon was analyzed.The result showed that the heaviest of watermelon was 190511.There was a very significantly positive correlation between fruit weight and watermelon position leaf character.The leaf area played a key role in fruit weight of watermelon.The leaf color played a direct role in fruit weight of watermelon.
