چکیده :

Comparison growing traits, phenol and flavonoids of stevia under field and greenhouse growth conditions were done during 2020-2021. In the field, plants were cultivated in five rows of 10 plants in each, and at the same time 20 potted plants were transferred into greenhouse with controlled temperature and humidity. Irrigation in the field treatment was drip. Greenhouse temperature between 25-30 degrees and humidity of 70 percent was set. The results of comparison of cultivation of this plant under field and greenhouse conditions showed that in field treatment, the highest mean values shoot height (67.75 cm), number of leaves (96.8), fresh weight of leaves and stems (0.213 and 15.23 g) and dry weight of leaves and stems (0.0607 and 5.5). The highest mean height (38.76 cm), number of leaves (69.25), fresh weight of leaves and stems (0.167 and 5.302 g) and dry weight of leaves and stems (0.0198 and 1.590 g) were highest mean values in greenhouse treatment. On the other hand, in greenhouse treatment, the highest mean values of leaves phenol (353.043 mg/g FW) and flavonoids (242.412 mg/g FW) and in field treatment had the highest mean values of leaves phenol (304.652 mg/g FW) and flavonoids (234.412 mg/g FW). Generally, farm cultivation showed a positive effect on growth indices, and growing at greenhouse was favorable for accumulation of phenols and flavonoids in this valuable medicinal plant.
