Effect of exogenous glucose and abscisic acid on physiological and morphological performances of in vitro indica rice (Oryza sativa L. sp. indica)

The aim of this research is to investigate on the osmolarity changes, sugar profiles, chlorophyll fluorescence and growth performances of indica rice cultured under exogenous glucose and abscisic acid (ABA). Osmolality in the root tissues of rice was positively related to increase glucose concentrat...
