Studies have been planned to estimate the effect of ethylene in rhizosphere on root growth. This experiments were carried out to determin the ethylene production from soil as affected by application of water, compost and methionine, an ethylene precursor in plant. The results obtained are summarized as follows: 1. The rapid evolution of ethylene was caused within one day by the application of water to the dry soil. The larger the application of water to the dry soil, the greater was the ethylene evolution from the soil. 2. The peak of ethylcne production was seen during five days after soil submergence, although the pattern of ethylene production was different depending on the condition of the soil. Ethylene production from the soil in submerged condition was greater in five to seven times than that from the soil in upland condition. 3. From the soil sterilizing test, it seems that ethylene production in submerged condition might be mainly occurred by an action of micro-organisms, whihe in upland condition non-micro-organic evolution of ethylene might be mainly occurred. 4. Compost was found to produce one hundred to five hundred times much more ethylene than dry soil. Ethylene production from soil was closely related to the amount of compost applied to the soil. 5. The production of ethylene from the soil was greatly stimulated by methionine application. As results of above, it is quite possible that ethylene in rhizoshere may act directly to root growth, and ethylene production in soil can be controlled by such as application of water, compost and methionine.
