Water deficit stress in the reproductive stage of four indica rice (Oryza sativa L.) supaibulwatana3
Relative water content (RWC) in the leaf of different rice cultivars dropped significantly in
relation to reduced soil water content (SWC), especially in PT1 and IR20. The water use efficiency in rice grown under water-deficit conditions declined significantly in comparison to the control group, leading to a reduction in net-photosynthetic rate.T
