Eucalyptus hybrid, ColchicineAbstract
Polyploids from cultured shoots of Eucalyptus hybrid (clones UP54 and UP99) were produced by treatment of colchicine. Results showed that the combination of 0.5% for 3 days was the most appropriate conditions for UP54 polyploidy induction with the induction rate of 33.33%; and for UP99, the combination of 0.25% for 4 days is the most effective with the induction rate of 24%. By comparing the tetraploid plants with diploid ones in morphology, leaves of polyploid plants were thicker, larger, and darker green.
