PROPAGATION OF NINE SPECIES OF PLANTS IN VITRO

Propagating techniques in vitro for the nine species of plants, Sequoia sempervirens (Lamb.) Endl, Cryptomeria fortunei. Rhododendron hybridum,Daphne adora var. marginota, Phalaenopsis sp., Hedera helix L. cv. Cauendishii, Begonia mecculata, Vitis vinifera L. cv. and Actinidia chinensis, are dealt with in this paper. The keys of the techniques for proliferating, rooting and transplanting are described. Success in vitro propagations of Cryptomeria fortunci and Hedera helix L. cv. Cavendishii have been first accomplished in China. In vitro propagation of some species achieved the level of mass production.
