Effects of Potassium Fertilizer on Diurnal Change of Photosynthesis in Stevia Rebaudiana Bertoni

Abstract:

Article Preview

The effects of potassium fertilizer on diurnal change of photosynthesis in Stevia rebaudiana Bertoni had been studied. Diurnal changes of net photosynthetic rate (Pn) and environmental and physiological traits in leaves of Stevia rebaudiana Bertoni were measured using LI-6400 portable photosynthesis system. The results showed that optimal potassium fertilizer can increased chlorophyll content and improved photosynthesis rate and decreased the chlorophyll a/b ratio. At the same time, midday depression of photosynthesis abated or disappeared.
