选取花萼未张开花蕾（长０．６～１．０ｃｍ）的黄色花药作外植体，在诱导培养基（ＭＳ＋６－ＢＡ２ｍｇ／Ｌ＋ＮＡＡ０．２～１．０ｍｇ／Ｌ）上分化出再生苗，经快繁培养基（ＭＳ＋６—ＢＡ０．５～１．０ｍｇ／Ｌ）继代培养８～１０次，于生根培养基（ＭＳ＋６—ＢＡ０．２５ｍｇ／Ｌ）上培养，最后一次性定植于温室壤土中，成活率在９０％以上。采用本技术，一年内一块分化组织可生产商品苗５０００～８０００株。脱毒苗比普通苗增产５４．５％。
The yellow anthers with calyx without opening buds (0.6 ~ 1.0cm in length) were used as explants to differentiate the regenerated shoots in the induction medium (MS + 6-BA2mg / L + NAA0.2 ~ 1.0mg / L) The medium (MS + 6-BA0.5 ~ 1.0mg / L) was subcultured for 8-10 times and then cultured in rooting medium (MS + 6-BA 0.25mg / L) Survival rate at 90%. Using this technology, a piece of differentiated tissue within a year can produce 5000-8000 commodity seedlings. Virus-free seedlings yield 54.5% more than normal seedlings.
