Abstract

Abstract Climate change made rain fall unpredictable leading to sudden drought stress during crop cultivation period. Osmotic stress induced by drought stress affect the crop growth and development especially during seedling period. This research aims to evaluate the performance of three local rice seedling under osmotic stress induced by PEG 6000. Three local rice cultivars were germinated and then divided into three groups. Three days after germination, each group were treated with either 0%, 15% or 25% PEG 6000 solution for 10 days. Osmotic stress induced by PEG significantly reduced plant growth and total chlorophyll content in the leaf. Among of the three cultivars, Mayas Putih was the most sensitive to the exposure of osmotic stress for 10 days at seedling stage. Additionally, osmotic stress induced increasing of soluble sugar in the leaf of all rice cultivars. This may indicate that soluble sugar play a role as osmoprotectant under osmotic stress in those three cultivars.
