白肋烟调制期间细菌菌株动态变化研究

目的]为了探明白肋烟调制期间对照与处理的细菌菌株动态变化.方法],在采收前1d,对白肋烟品种TN86进行WB5菌株喷洒处理,并设清水作对照,调制期间,每隔5d采集其烟叶样品,分析其不同调制时期的细菌菌株总量,探明其动态变化.结果]晾制期间烟叶中细菌总量在105 ～ 109 CFU/g,晾制初期(0～15d)菌量较高,晾制末期(30～45 d)菌量较低.结论]该研究可为白肋烟进一步的科学研究提供科学理论依据.

Study on the Change of Bacteria Strain of Burley Tobacco during Air-curing

Objective ]In order to prove up the variety trend of bacteria strain of burley tobacco during air-curing.Method] Spraying bacteria WB5 on the harvest leaves in the field test at 1 day before harvesting,and the CK was treated by spraying pure water,the tobacco leaves were collected every 5 days,then isolated bacteria from sample and counted,proved up their the variety trend.Result] The results showed that the total bacteria strain was 105-109 CFU/g during air-curing;The bacteria strain amount was higher during air-curing 0-15 days,while the total bacteria strain amount was lower during air-curing 30-45 days.Conclusion] The study provides a scientific and theoretical basis for deep science research on the burley tobacco.
