Abstract: 1) In order to know the degree of the symbiotic affinity by grafting between 8 kinds of the Cucurbitaceae and so many kinds of the Solanaceae, we have made grafting combination of 33 kinds for the former and 38 for the latter and made investigations of the condition and number of growth, and quantity of the yield of each of them. 2) As for the Cucurbitaceae, we have sorted them out into three groups; 1. Those that grow higher than the standard by using other stocks-a Citrullus valgaris Schad., Luffa cylindrica Roem., and Cucumis sativus L., 2. Those of the standard-a Cumis Melo var. Conomon Makino and Benincasa hispida Cogn. and 3. Those whose stocks are very effective. The Dutura Tatula L. proved to be very effective as a stock for the Solanaceae but in other cases such a remarkable effect as in the Cucurbitaceae has not been observed. 3) We have made a graph showing the relation of the symbiotic affinity. It is, however, presumed that degree of the symbiotic affinity shown in this way changes according to the circumstances. It is dangerous, therefore to take it to be a fundamental affinity which is sought for in the genetical close relation. 4) From the practical point of view, the Cucurbita moschata Duch., stock is most suitable for the Luffa cylindrica Roem. and Citrullus vulgaris Schad. and this stock must be particularly adopted as an immune stock of the former and as a good stock when the Citrullus vulgaris Schad., and the Cucumis Melo var. Conomon Makino are to be grown in a sterile ground. As for a Cucumis Melo L. the Cucurbita moschata Duch. is very high in the symbiotic affinity, but there remains a problem to be solved in terms of quality. The Dutra Tatula L. stock for the Solanum Melongena L. and the Lycopersicum esculentum Mill, is very good, even though there are also some problems for its practical use.
