It was reported in the writer's previous report that the germination of seeds of the three crops, namely, Abel, esculentus, Abel. Manihot and Nori-Asa, stored in dry state occurred very slowly as like as that of hard seeds. In this paper the results of some experiments on the cause and mechanism of it were reported. The materials were the seeds stored rot 3 years. Even if the seeds of Manihot were stored in dry state, the germination was good. But in esculentus and Nori-Asa the germination of seeds stored in dry state was very poor compared with the seeds stored in normal condition. This was due to the dehydration of seeds in the storing period, but the duration of life of deeds was not changed. The degree of poorness of germination was larger in esculentus than in Nori-Asa. This poor germination is due mainly to the difficulty in absorbing water. The water absorbing ability was the largest in Manihot, next comes esculentus and in Nori-Asa it was the smallest. In Manihot, this ability of seeds stored in normal condition was similar to those of seeds stored in dry state, but in esculentus and Nori-Asa, the ability was larger in the seeds stored in normal condition than that in seeds stored in dry state. The cause of the phenomena was due mainly to the palisade cells as well as the light line which has certain relation with the water absorbing ability. This was proved by the germination experiments in which the seed coat was injured by the grinder or it was treated with concentrated sulphuric acid.
