1. Authors tested the influences of NaCl Solutions upon the germination and the growth of seedlings of wheat, using a local variety named "Norin No. 52". 2. The decrease of both germination percentages and water uptake was circumstanced proportionally with the increase of concentrations of NaCl solutions. In regards to glucose solutions having osmotic pressures equal to NaCl solutions, they were perallely related, with those of NaCl solutions. But in cases of higher concentrations, seedlings in NaCl solutions grew poorer than those in glucose solutions. 3. In the case of sea-water, the growth fo young roots was larger than those in NaCl solutions. 4. A staining test by indigocarmine showed a striking decrease of vitality in cases of higher NaCl concentrations. 5. Reduction of enzyme activities, both amylase and peroxydase, was observed to be the same as in (2). It was not found, so far as this experiment is concerned that NaCl solutions of lower concentration promoted enzyme actions.
