Abstract: From May 1976 to July 1977, we made a series of investigations on the sporo- carps and cultured young sporophytcs of Azolla imbricata (Roxb.) Nakai. It is a green manure for higher yield of rice. But we know, that the means of cultivation of this plant is restricted to the vegetative reproduction. In most cases, Azolla withers in the very hot days in summer and bitterly cold days in winter. Out preliminary investigation indicates that the sporocarps can resist the unfavorable environment such as high temperature in summer and low temperature in winter. Young sporophytes have high plasticity. Therefore, it is of practical use to adopt sporocarps and young sporophytes as a means to overcome the unfavorable environment is of practical value. The appearance of its sporocarps in nature and the cultivated process of the young sporophytes are also briefly described.
