摘要
对11个烟草品种在云南不同生态区的产质变化进行了研究,结果表明:①参试品种在不同生态区种植,烟叶品质的变化大于产量变化,说明生态因素主要是影响烟叶的品质。②不同品种在同一生态区种植,品种间烟叶品质的差异大于产量差异,说明品种间的差异主要是品质上的差异。③不同品种在同一生态区种植,品种间的产质量差异小于同一品种在不同生态区种植生态间造成的产质量差异,说明生态因素间造成的产质变化大于品种间的变化。④各品种有其特定的适应区域,有些品种适应区域较广、适应性强,有些品种适应区域较窄,云烟85和K326适应性强,K358和K346适应性较强,云烟317和RG11适应性一般,红大、G28、NC82、V2、RG17等品种适应性较弱。
The yield and quality changes of tobacco varieties grown in different ecological zones were studied. The results showed that： （1） Quality changes were more obvious than the yield＇s for different tobacco varieties in different ecological zones, it meant that the effect of ecological factors was mainly on tobacco quality; （2） Quality difference was bigger than the yield＇s between the tested varieties in the same ecological zones, it meant that quality was main difference between varieties; （3） The quality and yield differences between varieties in the same ecological zone were smaller than that of the same variety in different ecological areas, it meant that the yield and quality changes caused by different ecological zones were bigger than those caused by different varieties; （4） Different varieties adapted to different growing zones, some varieties might be adaptable to wider ecological range and others might be not. The adaptability of Yunyan85 and K326 was the best, that of K358 and K346 was better, that of Yunyan317 and RG11 was moderate, and the others was the worst.
