Abstract
When the binucleate mycelial mat of Lentinus edodes was incubated in 0 .01% (w/v) colchicine solution for 10 days at 26 degrees C without sha king, hyperpolyploid nuclei accounted for 96% of the treated mycelial mat. A pair of hyperpolyploid nuclei was produced from a pair of norma l nuclei. Subsequently multiple smaller nuclei were generated graduall y from one hyperpolyploid nucleus. This phenomenon was called multinuc leation. The multinucleate body was superior to untreated mycelia in m ycelial elongation rate.
