Impact of low light stress on physiological contributing traits and biochemical parameter on early, medium and late rice genotypes (Oryza sativa L.)

Abstract:
The physiological and biochemical parameters like specific leaf area, specific leaf weight, total dry matter, apparent translocation rate, net assimilation rate, total dry matter at flowering and harvesting and protein content were significantly reduced under low light conditions. Conversely, the leaf area index (LAI) and total chlorophyll SPAD values showed an increase in response to low light condition. Notably, the early, medium and late genotype LL-604, LL-613 and LL-602 exhibited the maximum LAI among the tested genotypes under low light stress conditions. The leaf chlorophyll content was lower in full sun light conditions than in low irradiance environments. The exposure of low light among early, medium and late rice genotypes, the total chlorophyll SPAD values of LL-604, LL-613 and LL-603 recorded higher at panicle initiation and flowering stage.
