Studies on the Salt Injury in Rice Plant (preliminary Report) : (1) Absorption and Germination of Rice Seeds in Varying Concentrations of NaCl

[摘要] (1) We experimented on the absorption of water and germination of rice seeds in varying concentrations of sodium chloride. (2) The absorption of water increased rapidly during first 18 hours and then relaxed comparatively. (3) The increase of absorption of water was the highest in the plot of 0% of NaCl concentrarion(27%) and was the lowest in the plot of 3.0% (20%). (4) Relation between absorption of water and germination; the germination was aomost normal in the case between 0% and 0.6% (Absorption was more than 24%) and was not found in the case between 1.4% and 3.0%(Absorption was lower than 23%) (5) The quantity of NaCl contented in the seeds was the least in the plot of 0.06%(0.02% NaCl), increased in proportion to the noncentration of NaCl, and was the most in the plot of 3.0% (0.5%).
