This preliminary report deals with a few methods of inducing fiowering of mulberry plants in the sum mer-autumn season . Generally speaking, mulberry flowers, in the vicinity of Tokyo, are in bloom late spring, however the following four treatments showed to be successful methods in order to induce fiowering in the summer autumn season. 1 . One-year-old cut shoots severed off their crown in wintet or early spring, are stoted in a cool cellar at 5'C . These refrigerated shoots are taken out and cuttings are inserted late summer . 2. The hardened shoots of, the current years growth are severed off their crown at the suitable time (perhaps after August) and stored in a cool cellar at 5'C for about a month . These refrigerated shoots are taken out and cuttirigs are inserted . 3 . The current year's shoots of mulberry trees in the field are pruned late summer. 4 . The current year's shoots of mulberry cuttings in pots, to which the same treatment as the first case had been given early spring and has grown, are pruned late summer .
