Abstract:

Megastigmatrienone is an important natural aroma component of flue-cured tobacco, which has a great effect on tobacco flavor and taste. The formation and gene regulation of megastigmatrienone in tobacco leaves were summarized based on the function of megastigmatrienone. And the influences of genotype, ecological factors and cultivation measures on its content were expounded. This paper suggested that more emphasis should be put on studying the influences of various factors on syhthesis enzyme of megastigmatrienone, and put forth effort on mousing out the ordor recceptor of megastigmatrienone in nasal cavity, so as to improve tobacco quality purposefully, and provide theoretical basis for developing flue-cured tobacco of superior quality.

Key words: flue-cured tobacco, megastigmatrienone, gene regulation, genotype, ecological factor, cultivation measure
