Abstract: | Researches have been made on young panicle culture in vitro from wild rice of different genomes.Main results are as follows: 1. The induction frequencies of young panicle cultured in vitro from wild rice varied largely a relation to its genome. The optimal induction period of callus is the stamen and pistil differentiation stage of young panicle development. 2. Plantlets were regenerated through two ways: first, culture method, the induced calli were transferred onto differentiation medium; second, regenerate plantlets directly from young panicles of wild rice that were cultured on the differentiation medium. 3. The regeneration rate of green plantlets that obtained through cryopreservated calli in O. meyeriana was 10 times higher than that of control. |
