摘　　要：为研究四川晾晒烟叶片中钾含量及利用效率,对50份晾晒烟的幼叶和成熟叶片中钾含量进行测定,分析了50份四川晾晒烟的钾效率差异.结果表明:50份材料中有4个品种的钾积累效率大于2.0%,分别为Y1立耳子(2.91%)、Y2二柳叶(2.42%)、Y3黑牛皮(2.23%)、Y4黑牛皮(2.19%),在这4个品种中钾利用效率高于平均值9.89g的有2个品种,即Y1立耳子、Y3黑牛皮,这2个品种为钾积累和利用高效型品种.本研究为晾晒烟的高钾育种提供了理论依据.In order to provide a theoretical basis for Sichuan Sun-cured tobacco breeding,the contents of K in young and mature tobacco leaves were measured,and their K accumulation efficiency were also analyzed.The results indicate that there were four varieties,whose efficiencies of K accumulation were more than 2.0%,Y1（2.91%）,Y2（2.42%）,Y3（2.23%）,Y4（2.19%）,respectively.There were two varieties whose utilizing efficiencies of K were greater than the average of 9.89g among the four varieties.These two were effective varieties whose K accumulation and efficiency were higher than others.
