Abstract
In order to study the effect of commonly used biological agents for improving tobacco quality,and explore suitable method to promote high quality tobacco production,field experiment was carried out to study the influence of6 different biological agents on the physical and chemical properties,and the contents of neutral aroma components of tobacco after topping. The results showed that different biological agents had certain effects on tobacco leaf quality.Gibberellin( GA3) could improve the leaf width and length,single leaf weight,leaf density and stretching power.Thus,it effectively reduced the nicotine content and increased the contents of potassium and total nitrogen; improved the coordination between chemical components inside of tobacco leaves; and increased the aroma components content.So,gibberellin( GA3) had the optimal overall effect,and auxin took second place.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
