花椰菜的花球组织切段,可以利用MS培养基加BA 0.1mg/l及NAA 1mg/l,培养成为幼植株(试管苗)。用花序柄的切块,也可以培养成为试管苗、只需要一种培养基即可诱导产生芽及根。成活率达92～100％。 试管苗宜先从三角瓶移栽到花钵中,花钵盛以砻糠灰(稻壳灰)及砂作为基质。移栽的初期要加盖烧杯,以增加空气湿度、而水份由钵的底部上渗。经20到45天的培养可以育成大苗,然后栽到土壤中生长。又能形成花球。 由试管苗培养成为“自养”的植株的成活率为60～75％。
Cauliflower flower ball tissue section, can use MS medium plus BA 0.1mg / l and NAA 1mg / l, to grow into young plants (in vitro). With inflorescence handle cut, can also be cultured into a test tube seedlings, only one medium can be induced to produce buds and roots. Survival rate of 92 to 100%. Test tube seedlings should first transplanted from the triangular flask to the flower pot, flower pot filled with chaff ash (rice hull ash) and sand as a substrate. The initial transplanting should be stamped with beakers to increase the humidity of the air, while the water seepage through the bottom of the bowl. After 20 to 45 days of cultivation can grow into large seedlings, and then planted in the soil growth. Can form a flower ball. The viability of plants grown from in vitro seedlings to be “autotrophic” is 60-75%.
