Abstract:

In order to determine the suitable altitude for planting high-quality flue-cured tobacco in Panzhihua, the chemical composition, appearance quality and sensory quality of tobacco leaves at different altitudes (1800-2400 m) were compared and analyzed. The results showed that the sensory quality of tobacco leaves at different altitude showed a trend of 1800 m≈ 2100 m> 2400 m. The aroma quantity, aroma temperament, impurity and aftertaste of tobacco leaves were better at 1800 m than that at 2400 m. The appearance quality of C3F and B2F tobacco leaves decreased with the increase of altitude. The appearance quality of B2F tobacco leaves at 1800 m and 2100 m was significantly better than that at 2400 m. When the altitude was more than 2100 m, the nicotine content in the upper leaves was higher and the potassium content was lower, and the chemical composition coordination of tobacco leaves became worse. In conclusion, the altitude of 1800-2100 m is the appropriate altitude for planting high-quality tobacco leaves in Panzhihua, and the tobacco leaves have better appearance quality, chemical composition coordination, and higher aroma quantity and aroma temperament.

Key words: Panzhihua, tobacco leaf, altitude, sensory quality, chemical composition
