我们从一九七七年冬开始对杂交水稻进行组织培养的研究,初步获得成果,并掌握了从水稻的组织中大量诱导出二倍体植株的技术。水稻组织培养的研究是一个新课题,许多问题有待进一步揭示和认识。为了交流情况,特简报如下:一、材料与方法供试材料:用水稻籼、粳杂交和水稻“三系”的组合,选取发育期已进入胚囊母细胞和花粉母细胞开始分化的幼穗作接种材料,在无菌条件下,用0.5%的氯化汞液将 From the beginning of the winter of 1977, we studied the tissue culture of hybrid rice and got preliminary results. We also mastered the technique of inducing diploid plants largely from the tissues of rice. The research of rice tissue culture is a new subject, and many problems need to be further revealed and recognized. In order to exchange information, special briefings are as follows: I. Materials and Methods Materials for test: The combination of rice indica, japonica hybrid rice and rice “three lines” was used to select the embryo sac cells and pollen mother cells that had entered the developmental stage to begin to differentiate Spikelets were used as inoculation material and were aseptically treated with 0.5% mercuric chloride solution
