Result: The inductivity of leaves was the highest about 87.5%, followed with the stem section and leafstalk; The inductivity of nutrient medium such as MS, B5 callus was higher than the ones like H, SH and the White callus amended one; It was found that low-grade Phvalue benefits the growth of callus. The experiment result showed that different pH showed little difference in quality. The best condition of culture was 25 ℃in temperature. Conclusion: The best culture condition for callus was the leaves as explantation.
