Abstract:

The aim of this study is to establish a system of tissue culture and seedling production for Nandina domestica ‘Harbour Dwarf’. The stem segments of semi-lignified band buds were used as explants to conduct regeneration study. The comparative experiments, completely randomized orthogonal experiment design of L9(34), range analysis, significance test and LSD multiply comparative analysis were used to discuss the optimal culture medium. The results showed that the highest frequency of shoot induction (71.77%) and survival rate (85.51%) were achieved on MS + 6-BA 2.0 mg/L + IBA 0.1 mg/L + sucrose 30 g/L. The highest proliferation coefficient (6.3) was obtained on WPM +6-BA 1.5 mg/L + IBA 0.01 mg/L + sucrose 30 g/L. Microshoots exhibited best rooting response on 1/2 MS+ IBA 0.5 mg/L + NAA 1.0 mg/L + sucrose 20 g/L + AC 0.2 g/L by producing the highest frequency of root formation (97.63%). Rooted plantlets were transferred to artificial mixture medium (peat: perlite=3:2.V/V) under the green house condition with the survival rate up to 96.67%. An efficient propagation system of Nandina domestica ‘Harbour Dwarf’ was established, and the plantlets could steadily inherit the character of parents. The present system provides technical support for large scale plant production.
