Abstract
The osmotic regulation response of rice to soil salinity and alkalinity stresses was studied with mixed soils of saline-sodic soil and no saline soil.Exchangeable sodium percentage(ESP) of 2.41,13.67,25.67,42.30 and 53.13 was used as the stress treatment.The shoot biomass,electrolyte leakage,soluble sugar content and free proline accumulation in leaf at tillering,panicle initiating,filling and maturity stages of rice and grain yield were determined.The results indicated that the growth of rice was reduced by soil salinity and alkalinity,and yield decreased by 78.58 under severe stress.With the increment of the stress,the electrolyte leakage increased by 49.8%,45.0%,43.6% and 34.3% at four growth stages,respectively under severe stress.Soluble sugar content increased by 9.20%,59.40%,72.25% and 83.12% at tillering stage,and free proline accumulation increased by 87.71% and 167.80% under the stresses of ESP 42.30 and 53.13 in rice leaf.The sensitivity of the osmotic regulation response to soil salinity and alkalinity stresses in rice was higher in vegetative growth stage than in reproductive stage.The physiological response was enhanced under higher salinity and alkalinity stress.The results suggested that the appropriate increase of the stress can enhance the physiological responses in rice.
