Five upland rice varieties were subjected to soil moisture stress of 25% field capacity at seedling stage. With increase in soil moisture stress, there was decrease in relative water content and water potential of leaf. The cultivar which maintained high relative water content and positive turgor inspite of reduced leaf water potential during stress also had optimum photosynthesis and solute accumulation as evident from osmotic potential.
