摘要
为了解津巴布韦烤烟品种特性,在云南1 120～1 660 m中低海拔区域进行了2个津巴布韦烤烟品种的比较试验。结果表明:KRK23和KRK26品种打顶株高、茎围、节距、最大叶宽及其叶面积比K326大,有效叶数比K326多;田间黑胫病、青枯病、普通花叶病自然发病率高于K326,4种叶斑类病害的发病率低于K326,KRK26对7种烟草病害的田间综合抗性优于KRK23。从经济性状的丰产性及其稳定性看,KRK26较好,K326和KRK23稍差。2个品种烟叶还原糖含量比K326低,钾含量和多酚总量比K326高,总氮和烟碱含量与K326相当,KRK26烟叶主要化学成分含量的协调性好于K326和KRK23。KRK26综合表现优于K326和KRK23,KRK23较K326差。
In order to understand the characteristics of flue-cured tobacco varieties introduced from Zimbabwe,a comparative experiment on two varities,i.e.KRK23 and KRK26 was carried out in low and mid altitude regions（from 1 120 m to 1 660 m） in Yunnan with K326 as the control.The results showed that the height of topping plant of the two varieties from Zimbabwe were higher than that of K326,the stalk circumference,the internode length,leaf width of the biggest leaf were the same and the curable leaf number of the two varieties from Zimbabwe were larger than those of K326.The field occurrence of Black shank,Granuville wilt and Tobacco mosaic virus in the two varieties were higher than in K326,and the incidences of four kinds of leave spot diseases in the two varieties were smaller than in K326.Viewd from the economic traits high-yield and stability,KRK26 performed better than K326 and KRK23.The contents of the reducing sugar in the leaves of KRK26 and KRK23 were higher than that of K326,and the contents of potassium and total polyphenols of the two varieties were higher than those of K326.The contents of total nitrogen and nicotine in the leaves of the two varieties were equal to that of K326.KRK26 had better coordination in main chemical components than K326 and KRK23.The comprehensive performance of KRK26 was better than that of K326 and KRK23;and that of KRK23 was poorer than that of K326.
