郁金香、水仙、风信子等都是有代表性的球根花卉,繁殖系数较低。尤其是风信子,其鳞茎基本上不能自然分球。因此大量繁殖时,通常采用刻伤或挖孔方法,促进母球从基部产生子球,也有采用鳞片扦插形成不定芽培养小球根苗繁殖法的。为了大量快速繁殖无病毒风信子苗,最近进行了组培育苗实验。
Tulip, narcissus, hyacinth and so on are all representative bulbous flowers with lower reproductive coefficients. In particular, hyacinth, the bulb basically can not naturally point the ball. Therefore, a large number of breeding, usually using carved or digging method to promote the cue ball from the base to produce sub-ball, also have the use of scales to form adventitious buds of small ball seedling propagation method. In order to reproduce a large number of virus-free hyacinth seedlings, recently conducted a group of nursery experiments.
