Abstract:

Zantedeschia Aethiopia was treated with colchicines at different concentration and time duration in vitro. The results showed: the best effect was obtained by the treatment of 0.05﹪ colchicines with 24 hours, and its induction rate was 52%. Chromosome observation found that the chromosome number of treated plants was 64, and the chromosome number of the control was 32, indicating the tetraploid (2n =4x=64) of coloured Zantedeschia aethiopica is induced successfully.



Key words: Zantedeschia aethiopica, colchicines, polyploid, chromosome
