RAPID PROPAGATION AND POLYPLOIDY INDUCTION IN SCINDAPSUS AURUS CV. WILCOXII

ZHANG Xing-cui(College of Agronomy and Life Science, Southwest Agricultural University, Chongqing 400716, China)  
Under aseptic conditions, caespitose shoots of Scindapsus aurus were dipped in 0.05%,0.1%,0.2% and 0.5% colchicine solutions for 1 day and then transferred to MS + 6-BA 3 mg/L + NAA 0.5 mg/L. Thirty days later shoots were successfully induced in all the four treatments. Examination of the chromosomes of the root tip cells of the regenerated plantlets revealed that they were either tetraploids or chimeras. Treatment with colchicine solution at 0.2% for 1 day gave the best results and 75% of the variant buds obtained were tetraploids with a chromosome number of 116 (2n=4x=116) as compared to the diploid counterparts (2n=2x=58).
