摘要

The toxic action of 2.4-D and that of potassium chlorate on rice plants were studied. Tillers cut from rice plants about 62 days and 72 days old were treated with 0.5% solution of 2.4-D and 0.1% solution of potassium chlorate. The results were as follows : 1. The toxic action of 2.4-D was stronger on the tillers of lower orders, and weaker on the tillers of higher order. 2. On the contrary, the toxic acion of KClO3 was stronger on the higher order tillers. The mechanism of the toxic action of 2.4-D was ascribed to the carbohydrate dissipation in the plant, that of KClO3 to the physiological reduction of it in the plant body.
