实践证明,采用芽尖培养法繁殖著名的切花材料满天星,比扦插法速度快,发根率高,而且无病,开花多而优,并有“返老还童”的倾向,可使生产急剧增长,值得推广和普及。一、初代培养 1.取材与调整:原则上茎顶芽、侧芽等都可以用作培养中才料,但以位于母株新梢中下部(第3——4节)的侧芽为好,因其发育程度适中。培养前,先用利剪取下此部分,去掉叶片后再用利刀切成长3——5厘米的一段,并用中性洗剂和净水充分冲洗,放入带盖的玻璃容器内(如烧杯等),用杀菌剂表面消毒
Practice has proved that the use of shoot tip culture reproduce the famous cut flower materials Gypsophila, cuttage faster than cutting method, high rate of hair roots, and disease-free, flowering and more excellent, and there is “rejuvenate” tendency, can produce a sharp increase in production , It is worth promoting and popularizing. First, the primary culture 1. Drawn and adjusted: in principle, stem buds, lateral buds and so can be used as training materials, but in the lower part of the new plant shoots (Section 3 - 4) of the lateral bud is better because Its development is moderate. Before training, remove this part with Lee cut, remove the leaves and then cut with a knife to grow 3 - 5 cm section, and fully rinsed with neutral detergent and water, placed in a covered glass container (such as Beakers, etc.), with disinfectant surface disinfection
