摘要
利用分离自不同生境烟叶上的微生物真菌菌剂处理烤烟同一部位烟叶,结果分析表明,真菌菌剂BF06,BF07处理烟叶后,烟叶内与烟叶品质相关的主要化学成分含量发生了改变,烟叶内的淀粉含量有不同程度的下降,微生物代谢产物对降解烟叶中的淀粉、蛋白质含量起到促进作用,使烟叶中的淀粉、蛋白质等大分子物质转化成产生烟叶香气的前体物质,烟叶品质得到改善。烟叶内糖、氮、烟碱、蛋白质等主要化学成分含量及各种成分之间比例更趋于协调。感官评吸鉴定认为:真菌菌剂BF06,BF07处理的烟叶香气质提高,香气量增加,刺激性减小,余味舒适,烟叶品质明显高于对照。
Several epiphyte agents isolated from different habitats were sprayed to the tobacco leaves at similar positions of the plants. Of the agents studied, BF 06 and BF 07 markedly changed the contents of the chemical substances associated with the quality of tobacco leaves. Starch in the treated leaves decreased to different extents. The metabolites of the microorganisms degraded the starch and protein in the leaves and converted them into the precursors of aroma substances, thus improving the quality of the tobacco leaves.
