不同基因型烤烟中性致香物质含量的对比分析

对南阳烟区10个不同基因型烤烟品种烤后上部和中部烟叶的中性致香物质含量进行了比较分析.结果表明:上部叶中性致香物质总量由高到低为中烟98、云烟87、云烟85、K326、8541、中烟100、NC89、中烟101、9717、39511;中部叶中性致香物质总量由高到低为云烟87、中烟98、云烟85、K326、8541、中烟100、39511、NC89、中烟101、9717.不同基因型烤烟叶片间中性致香物质含量差异明显,综合表现较好的是中烟98、云烟87、云烟85,综合表现较差的是9717、中烟101、39511,说明中烟98是南阳烟区最适宜的品种,其次是云烟87和云烟85.

Content comparison of aroma constituents in different genotypes flue-cured tobacco leaves

Content of aroma constituents was compared in ten of flue-cured tobacco cultivars produced in Nanyang area.The results indicated that total content of neutral aroma constituents in upper leaves varied from high to low was Zhongyan98,Yunyan87,Yunyan85,K326,8541,Zhongyan100,NC89,Zhongyan101,9717,and 39511,respectively.Total content of neutral aroma constituents in middle leaves was Yunyan87,Zhongyan98,Yunyan85,K326,8541,Zhongyan100,39511,NC89,Zhongyan101 and 9717.There was a significant difference of content of aroma constituents among different genotypes.In general,Zhongyan98,Yunyan87 and Yunyan85 showed better,and 9711,Zhongyan101,39511 showed worse.The study indicated that Zhongyan98 was very suitable for being cultivated in Nanyang,then was Yunyan87 and Yunyan85.
