Title

The Effects of Water Stress on the Grain-filling in Rice

Tohru KOBATA; Shinichi TAKAMI Japanese Journal of Crop Science 1979. doi:10.1626/jcs.48.75

Other claims from this paper (5)

Intervention effect Soil desiccation produced a more evident progressive decline in rice relative water content.
Observation Stomatal aperture and transpiration changes indicated more severe stress in desiccated plants.
Intervention effect Unhulled rice dry weight increase differed little between desiccated and control plants over 10 days.
Intervention effect Total dry matter increase was significantly reduced in desiccated plants.
Observation Authors conclude water stress has little effect on rice translocation during rapid grain growth.
