以朱顶红花器官或鳞茎切块为材料,在Ms+IAA0.1-1毫克/升或NAA0.01-0.5+6-BA0.5-2毫克/升的培养基上诱导成苗,对组培株分球习性、生长能力、开花习性进行了观察。当母球鳞茎平均为6.19cm时,子球年分化率为14.56,是一般分球繁殖的5-7倍。母球球径大小与子球数、子球径相关性极显著。随母球球径的增大,球径年增长率明显下降,一般5cm以上种球抽?率为100%,花期明显提前。7cm以上种球花序数明显增加。
In order to induce the seedlings to grow in the medium of Ms + IAA 0.1-1 mg / L or NAA 0.01-0.5 + 6-BA 0.5-2 mg / L, Strains ball habit, growth ability, flowering habits were observed. When the average bulbs of the parent ball 6.19cm, the annual rate of sub-ball 14.56, 5-7 times the general ball multiplication. The size of the ball of the mother ball has a significant correlation with the ball number and the ball diameter. With the increase of the ball diameter of the ball, the annual growth rate of the ball diameter decreased obviously. Generally, the ball pumping rate of 5cm ball or above was 100%, and the flowering time was obviously advanced. 7cm above the number of bulbs increased significantly.
