| Abstract: | Chemical mutagenesis can create a variety of mutants effectively. Mutagenic efficiency can be improved if the appropriate conditions for mutagenesis are determined. In this paper, we employed the immature secondary somatic embryos of anther from the Brazilian rubber tree Reyan 7-33-97 as material, and then we set four treatment levels, containing 0%, 0.1%, 0.3% and 0.5%, respectively, and four treatment time, which was 2 h, 4 h, 6 h and 8 h, respectively, a total of 16 combinations treated with chemical mutagen EMS. The results showed that it could reach the "half lethal dose" effect when the treatment time was 4 h and the concentration was 0.5%. |
