Abstract: With Logistic equation and multipe regression, the respondent models of the flowering, the amount of flowers and pods and the abscission to light, moisture and temperature at nights are established. The flowering process is in line with the logistic curve. Lack of soil water results in the advanign of the first flowering time and half of maximum flowers per plant. The flowering and half of maximum flowers will be postponed under shading. Forces of enviroment shortens flowering time and decreases the amount of flowers and pods. Moisture has a greater in fluence upon the amount of flowers than light has, while less influence upon the amount of podding than light has.
