[Rapid propagation of Smilax glabra in vitro].

In vitro propagation of Smilax glabra Roxb. was studied. The results indicated that sterilized explants cultured on MS + 6-BA 1.0 mg/L + NAA 0.1 mg/L could lead to budding fastly, the medium MS + 6-BA 1.0 mg/L + NAA 0.1 mg/L + 15% CM suitable for the proliferation, 3/2MS + 6-BA 0.05 mg/L + 4% Sugar suitable for buds strong. Treatment on the medium H (modified) + NAA 0.5 mg/L was best for rooting. The survival rate of the test-tube plantlets was 95% in transplanting on media contained turf-sand (1:1).

[Asepsis sowing and tissue culture of Bletilla striata].

The asepsis sowing and tissue culture of Bletilla striata were studied. The results indicated that the embyro culture had highest sprouting percent and plantlets percent when their embryos were mature. The optimal medium for the embryo culture was 1/2 MS. Adding 10% coconut juice can promote embyros sprouting and plantlets formation, 1% active carbon can improve plantlets growing. The best medium for the top of plantlet on culture and multiplication was 1/2 MS + 6-BA 0.5 mg/L + NAA 0.2 mg/L. The best medium of rooting was 1/2 MS + NAA 0.5 mg/L, and 10% banana juice can improve rooting of plantlets.

[Diseases and its control on Dendrobium].

The diseases on the Dendrobium plants and their occurrence and damage as well as control methods have been investigated and studied. 11 kinds of fungi, 4 kinds of bacteria, 3 kinds of virus and one root-knot nematode were recorded. To control them effectively, cultural methods such as selecting cultivable field, keeping the field sanitation, enhancing cultural operations are mostly recommended. The application of chemical germicides is also stressed.
