用秋水仙素处理二倍体西瓜,诱导成四倍体,再与正常二倍体西瓜杂交产生三倍体西瓜,即无籽西瓜。无籽西瓜这种年年必须制种的程序,不仅手续较为复杂,而且种子产量和成苗率较低,使无籽西瓜生产受到很大限制。 1979年北京海淀区农科所与中国科学院植物所、北京林科所协作,利用“红花”三倍体无籽西瓜种子,经组织培养获得大批芽团,并诱导生根成苗,但移入土壤均未成活。后经参照国内外 Treated with colchicine diploid watermelon, induced into tetraploids, and then with the normal diploid watermelon hybridized to produce triploid watermelon, seedless watermelon. Seedless watermelon this year must be planted seed production procedures, not only more complicated procedures, and seed yield and seedling rate is low, so that seedless watermelon production has been greatly restricted. In 1979, the Institute of Agronomy, Haidian District, Beijing, cooperated with Institute of Botany, Chinese Academy of Sciences and Beijing Forestry Research Institute. Using the “Tripterygium” seedless watermelon seeds, lots of shoots were obtained through tissue culture, Not survive. After reference by the domestic and foreign
