Evaluating the non-destructive method for determining the chlorophyll and nitrogen content in Stevia rebaudiana (Bertoni) leaf

Abstract

Leaf chlorophyll (Chl) content is an indicator of photosynthetic activity, stress condition and nutritional status of a plant. The efficacy of a hand-held Chl meter (CCM-200) for non-destructive estimation of total Chl and nitrogen content in the stevia (Stevia rebaudiana Bertoni) leaves has been evaluated.
