Abstract
Cell suspension culture of two sweet potato( Ipomoea batatas L. Lam) genotypes, Nanshu 88 and 8129 4, was established from the calli derived from leaves. The growth curve of two clones of cell suspension was sigmoid, and the growth rate of Nanshu 88 was three times higher than that of 8129 4 on average. The cell fresh weight of 10 day culture of Nanshu 88 was 10 times higher than that of initiation. For Nanshu 88 optimal concentration of 2,4 dichlorophenoxyacetic acid (2,4 D) and sucrose in MS medium was 1.0 mg L -1 and 3 g L -1 respectively, and addition of coconut milk and yeast extract increased the growth. For 8129 4 the optimal concentration of 2,4 D and sucrose in the medium was 2.5 mg L -1 and 1.5 g L -1 respectively, and coconut milk had no effect on growth, but yeast extract stimulated growth dramatically. The casein hydrolysate had a little effect on the growth of the cell suspension culture, and single amino acids added into the medium (such as glutamine、tryptophan and proline) could not increase the growth at all. Glucose was shown to decrease the growth rate.
