Diatomite alleviates the adverse effects of salinity stress on growth and yield of Stevia rebaudiana
Journal Title: International Journal of Advanced Biotechnology and Research. - Year 2016, Vol 7, Issue 1
Abstract
ABSTRACT The present study was planned to investigate the role of diatomitein salt tolerance of Stevia rebaudiana using pot experimental. Diatomite increased the growth characters of plants, hence resulted in higher yields. In contrast, the seawater treatments alone significantly decreased these parameters in both seasons. While, treating Stevia rebaudianaplants with diatomite prior to salinity stress decreased the detrimental effectof salt stress on growth and yield.The Esterase isoenzymesprofiles has indicated that salinity, diatomite and their combinations has caused biochemical changes in Steviar. plants. On the other hand, saline water irrigation decreased Rebaudioside A concentration at the second harvest as estimated by HPLC analysis in both seasons .The effect of the interaction between salinity and diatomite was the mosteffective treatments for Rebaudioside A when Stevia rebaudianaplants treated by salt concentration 4000 ppm and 2.5 g/kgsoil diatomite.
