The effects of different growing conditions (open field and polyhouse) were investigated on stevioside and rebaudioside-A content of Stevia rebaudiana plant. The experimental results revealed that stevioside and rebaudioside-A content were maximum at pre-flowering growth phase followed by flowering and post-flowering phase under both experimental conditions. Leaves showed maximum stevioside (9.19%) and rebaudioside-A content (7.00%) under polyhouse and open field conditions, respectively. However, minimum stevioside and rebaudioside-A content (< 1.00%) was observed in green and woody stem.
