To study the injury of seeds by soaking in water, the writer used those of Phaseolus vulgaris L. The seeds were soaked in the tap water passed through the ion-exchange resin and kept at temperature of 25℃. It was shown that soaking injury is influehced by the amount of moisture which a seed contains before soaking in water. The harmful effect by subsequent germination considerably increased in the seeds dried in the decicator with calcium chloride at the room temperature. On the other hand, it decreased for the seeds that absorbed moisture in the moist chamber. L.V.BARTON(1950,1952)reported that the water absorption rate of the bean seed is related to the soaking injury. In this experiment, all of the seeds contained the same quantity of moisture after soaking in water for 4 to 6 hours, but the dry seed absorbed a greater quantity of water than the wet one during soaking. It seems that the amount of moisture which a seed contains before soaking has relation with the quantity of absorption of water during soaking and this results in afecting the subsequent germination of the seed. Soaking injury differs according to the condition of preservation of the seeds.
