The root hairs of the crown roots of the low1and rice plants cultivated in the upland fields were numerous in number and longer in length, as compared to their development and growth in the paddy fields. The size and shape of the short cells, etc.) in the epidermis were also different, for instance the ratio of length/width was smaller than that of the roots in the paddy fields and sometimes the short cells looked like a barrel (fig. 1A). The root hairs in the paddy fields, as usual, were straight, but on the contrary, the root hairs in the upland fields may frequently take any shape (figs. 2A, B and C). In general, the percentage of root hairs containing RNA was very low in the upland field plants as compared to those of the paddy fields, excepting those hairs growing near the root tips. From these results it may be concluded, that the number and length of root hairs of the crown roots in the upland fields are better, but the physiological activity of them is not so higher than those in the paddy fields.
