水稲の根における根毛の形成について

The morphological studies on the development of the root hairs in rice plants which were grown in various conditions with reference to soils, were carried on in this experiment. It was found that the root hairs of the seedlings in the moist chamber were produced at about 1000μ from the root tip and at about 4.1∼13.0 mm in the paddy fields. Generally the root hairs were formed in the short cells of the epidermis of the root with polarity. When the soil of the paddy field was in the way of oxidation, the root hairs were found at farther distance from the root tip than in the reductive soil and furthermore they were numerous in number and longer in length. On the contrary, the formation of them was poor when the soil was reductive.
