【摘要】 通过不同生态区烟草品种产质变化研究表明:①不同品种在不同生态区种植,烟叶品质的变化大于产量的变化,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的差异,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,品种间产质差异小于不同品种在不同生态区种植产质的差异,说明品种内生态间的产质变化大于品种间的变化。④参试品种各有其特定的适应区域,有的品种适应区域较广,有的品种适应区域较窄,云85适应性最强,K326,K358和K346适应性较强,317和RG11适应性中等,其它品种适应性较弱。更多还原

【Abstract】 The research was focused on the yield and quality changes of tobacco varieties grown in different ecological zones.The results indicated that when different varieties were planted in different ecological zones,the quality variations of tobacco leaf between different varieties were greater than those of yield,which meant that the ecological factor was the major influence on quality of tobacco leaf and variations between varieties was due to the quality differences.Also the yield and quality variations between different varieties grown in same ecological zone were smaller than those of different varieties grown in different ecological zones,which indicated that the yield and quality differences between ecological zones were greater than those between varieties. The tested varieties had different adaptabilities,Yunyan 85 with the highest adaptability, K326, K358 and K346 with a higher adaptability, Yunyan 317 and RG11 with a moderate adaptability,and other varieties with a weaker adaptability.更多还原
