Abstract

|
Optimum conditions for rooting of hardwood cuttings of two mulberry varieties have been determined with respect to the concentration of IBA applied to the base of cutting, dipping depth into IBA solution, season of cutting collection and rooting medium in the bottom heat bins. 1. Optimum range of IBA concentration was 2,000 p.p.m.∼4,000 p.p.m. in Sariasi and Ichinose. 2. Most optimum dipping depth of cutting was 2.5 cm from the base of cutting 3. Rooting occurred most readily during December and March. 4. Perlite was the best medium to produce hardwood cuttings in the bottom heat bins.
