摘要： Polyploidy is a potential way to breed new varieties with high yield and stress resistance in plants. In this study, we provided an efficient method for induction of tetraploid of Hevea brasiliensis by immerse somatic embryos in the liquid plant induction medium containing colchicine. The optimum concentration of colchicine is 5 mg/ml, and the optimum immersion time is 24-48 h. The highest average induction rate of tetraploid is 27.12% in Reyan73397 with 5 mg/ml colchicine for 48 h, and 38.89% in Reyan87662 with 5 mg/ml colchicine for 24 h. Finally, 82 tetraploids of Reyan73397 and 14 tetraploids of Reyan87662 were obtained. Compared to diploids, tetraploids exhibited less and lighter leaf veins, daker and thicker leaves, larger stomatal size and smaller stomatal density. These tetraploids have the potential to be used as parents to produce new triploid germplasms in Hevea brasiliensis breeding programs.
