大白菜(Brassica Pekinensis Linne)为二年生蔬菜,在自然情况下,一年只能繁殖一代.为研究探索加速大白菜世代进程的途径和方法,达到缩短育种年限的目的,我们于1980年在本所进行了大白菜春化处理秋季采种的研究.材料和方法试验材料采用小白口(早熟品种)、洛阳二包头(中熟品种)、洛阳大包头(晚熟品种).春化处理前,进行浸种催芽,待大部分种子萌动时,把种子放到铺有湿滤纸的培养皿内,然后放入冰箱中,在无光条件下进行 Chinese cabbage (Brassica pekinensis Linne) is a perennial vegetable, which can only reproduce one year in a natural situation.In order to explore ways and means of accelerating the generation of Chinese cabbage and shorten the breeding time, We studied the autumn seed-picking of vernalization of Chinese cabbage.Materials and Methods The materials of the experiment were: Xiaobaikou (early maturing variety), Luoyang Er Baotou (middle maturing variety) and Luoyang Baotou (late maturing variety) Germination, most of the seeds to be germinated, the seeds into the wet filter paper Petri dishes, and then placed in the refrigerator, in the absence of light conditions
