The author tried experiments on regeneration by means of cutting with materials, Portulaca grandiflora (sun plants) arid Sedum lineare (shadeplants); comparing the groups unscreened after screening a; certain period with the control-groups unscreened. Kinds of method compared were as follows: I. Of Portulaca grandiflora, HooK. A. Unscreened (as control). B. Unscreened after screening a certain period. 1. Screened with one sheet of white cloth one day long. 2. Screened with one sheet of white cloth two days long. 3. Screened with two sheets of white cloth one day long. 4. Screened with two sheets of black cloth one day long. II. Of Sedum lineare, THUNB. A. Unscreened (as control). B. Unscreened after screening a certain period. 1. Screened with one sheet of white cloth two days long. 2. Screened with two sheets of white cloth two days long. 3. Screened with two sheets of black cloth two days long. In the case of P. grandiflora, the degrees of regeneration were such an order as B-4, B-3, B-2, B-I and A, having the least result in A; namely the most prominent result was obtaind from the most intensively screened. Of S. lineare, the order of degrees was B-2, B-I, A and B-3; consequently the most prominent result being obtained from the cuttings screend with two sheets of white cloth two days long. It is noteworthy that B-3 fell below the control material A. (Biological Laboratory, Fukuoka Woman's College)
