Abstract

Abstract: Using Dendrobium vietnamense as plant material and calcium silicate as the exogenous additive, the calcium silicate concentration that was most suitable for adding to protocorm induction medium and strong seedling rooting medium of Dendrobium vietnamense was selected. The results showed that the most suitable calcium silicate concentration added to the protocorm induction medium of Dendrobium vietnamense was 0.2 g/L, and the protocorm induction rate was 71.43%; the best anti-browning effect of tissue culture seedlings of Dendrobium vietnamense could be obtained when the calcium silicate concentration was 0.5 g/L; the optimum calcium silicate concentration for plant height growth was 0.4 g/L; the calcium silicate concentration with the largest number of branches was 0.3 g/L; the concentration of calcium silicate with the largest number of leaves was 0.3 g/L; when the concentration of calcium silicate was 0.3~0.5 g/L, the rooting effect of Dendrobium vietnamense was better.

Key words: Dendrobium vietnamense Aver., tissue culture, calcium silicate, protocorm, growth and development
