| 摘 要： | 测定了5个马铃薯品种的叶面积和系数法的矫正系数,进行了叶面积与块茎产量和品质的相关性分析。结果表明,5个马铃薯品种的叶面积和矫正系数(K)具有极显著差异,矫正系数不能在品种间通用。叶面积与产量有显著的正相关,但与淀粉、蛋白等品质指标无相关性,表明叶面积的增加能加强光合产物的输出,提高马铃薯的经济产量。

| Abstract: | The leaf area and corrected coefficient of five potato varieties were measured and furthermore the correlation between leaf area,and yield and quality was analyzed.The results showed that the leaf area and corrected coefficient of five potato varieties had highly significant difference and the coefficient obtained in one variety would not be applied in another.Moreover,leaf area had significant positive correlation with tuber yield but not with any quality trait.These suggested that the enlargement of leaf area could enhance the export of photosynthetic product and cause increase in economic yield. |

| Keywords: | potato leaf area corrected coefficient yield quality |
