Variations in seed viability across rice genotypes under aged and non-aged conditions. a Photograph showing TTC staining of rice genotypes showing variation in seed viability under control and accelerated ageing conditions. The photographs were taken after one day of incubation in TTC stain. b Variability in dehydrogenase activity as quantified by reduction in TTC levels over control showing differences in seed viability, (n = 10) (Alphabets with same letters are non-significant at p = < 0.05). c Relationship between seed viability (an indication of TTC reduction) and membrane damage in rice upon ageing treatment and d Effect of pH on dehydrogenase activity (as indicated by TTC reduction) in rice seeds upon ageing treatment
