Abstract

Abstract: In order to investigate the effects of five plant growth regulators on the yield and quality of flue-cured tobacco, 4% GA₃water agent, 0.136% GA·IAA·BR wettable powder, 0.01% BR soluble agent, 0.1% S-inducer water agent and 6% ascorbic acid water agent were selected, field experiment was conducted to measure and analyze the agronomic characters, economic characters and chemical components. The results showed that after spraying 4% GA₃ water agent and 0.01% BR soluble agent, the growth of tobacco plants was the fastest and the pitch increased significantly at resettling stage; spraying 6% ascorbic acid could increase the number of leaves to 21.6, which can promote the opening of topper leaves. Plant growth regulators could promote the absorption of potassium by tobacco plants. The potassium content of flue-cured tobacco leaves increased significantly. 6% ascorbic acid water agent decreased the nicotine content of middle and lower leaves significantly, and 4% gibberellin water agent decreased the nicotine content as a whole. Five plant growth regulators had different effects on the economic properties of flue-cured tobacco, and praying 6% ascorbic acid agent was the highest. Taken together, 6% ascorbic acid could improve the quality of tobacco leaves and increase economic benefits under drought stress.

Key words: plant growth regulator, flue-cured tobacco, agronomic character, economic character, chemical composition, drought stress
