[目的]筛选适宜皖南生产的优质“焦甜香”风格烤烟品种。[方法]采用小区试验方法比较研究在宣城种植的5个烤烟品种的生理变化、化学成分、农艺性状、经济性状等,筛选适宜皖南生产的优质“焦甜香”风格烤烟品种。[结果]各品种中,K326的丙二醛(MDA)含量比其他4个品种要高,而云烟97的MDA含量则相对较低;NC297上部叶类胡萝卜素含量在前期保持较高的水平,后期降解较快,说明NC297烟苗更有利于各种致香成分的积累;K326中上部叶的转化酶始终保持较高的活性,有利于干物质的积累;云烟97具有更好的生态适应性;云烟97和6517的产量和产值最高。[结论]在皖南地区,云烟97和6517的化学成分协调、经济性状比较优良,抗逆性较强,为该区较为适宜的“焦甜香”风格烤烟品种。
[Objective] The research aimed to screen the best quality “Jiao Hong Xiang” style flue-cured tobacco varieties produced in southern Anhui. [Method] The physiological variation, chemical composition, agronomic traits and economic traits of 5 flue-cured tobacco grown in Xuancheng were comparatively studied by plot test method. The best quality “Jiao Tian Xiang” style flue-cured tobacco varieties suitable for production in southern Anhui were screened. [Result] The content of malondialdehyde (MDA) of K326 was higher than that of the other four cultivars, while the content of MDA of Yunyan 97 was relatively low. The content of carotenoid of upper leaves of NC297 kept a relatively high level in the early period, The late degradation is faster, indicating NC297 tobacco seedlings are more conducive to the accumulation of aroma components; K326 in the upper leaves of the invertase has always maintained a high activity, is conducive to the accumulation of dry matter; Yunyan 97 has better ecological adaptability ; Yunyan 97 and 6517 the highest yield and output. [Conclusion] In the southern part of Anhui Province, Yunyan 97 and 6517 had better chemical characters, better economic characters and stronger resistance, which was more suitable for this area.
