Abstract:
Objective To solve the caducity question of Dendrobium officinale during the tissue-culture process. Methods Added the different concentration of 0.1 and 2 mg/L AgNO3 into the PLB proliferation medium, buds proliferation medium, and rooting medium separately. The quantity of the ethylene production was to be determined and the situation of the tube seedling growth was to be observed. ResultsAgNO3 can suppress the production of the ethylene, enhance the multiplication speed of PLB and split-up efficiency the clump of bud, and obviously promote the seedling′s growth. It showed that the survival ratio of transplant could enhance as many as two times and display the merit of caducity-resistant. ConclusionAgNO3(1 mg/L) can be taken as the caducity-resistant reagent of D. officinale during the tissue-culture processing.
