The invention discloses a sterile seeding and propagation method of Huangwei, which comprises the following steps: (1) from June to July, the seeds of Huangwei are ripe, the lignified but not cracked seeds are collected and stored at 4 ~C for one week, the shell of the fruit is removed, the seeds are taken out and sterilized to obtain sterile seeds; (2) the shell of the sterile seeds is scraped and the seeds to be inoculated are obtained; (3) the seeds to be inoculated are inoculated into the basic culture. Culture in medium; (4) After one week in basic medium, seeds cultured in basic medium were placed in seed germination medium for 2-3 weeks to obtain seedlings; (5) seedlings were inoculated into proliferation medium for multiplication culture, and seedlings were re-cultured in the same way every 2-3 weeks to get germination; (6) single buds were cut from buds and transplanted. After culturing in strong seedling culture medium for 1-2 weeks, the cluster seedlings are obtained; (7) After transplanting the cluster seedlings into rooting culture medium for 1-2 weeks, the tissue culture seedlings are obtained until all the cluster seedlings have rooted; (8) The tissue culture seedlings are transplanted into the moss medium and cultivated for 1-2 months to mature seedlings; the invention improves the germination rate, the reproduction speed and the transplantation survival rate.

一种黄薇的无菌播种繁殖方法
本专利技术植物繁殖
,具体涉及一种黄薇的无菌播种繁殖方法。
技术介绍
黄薇(Heimiamyrtifolia)为千屈菜科黄薇属的落叶灌木,南美当地称为太阳花或黄顶灌木。黄薇属原产自美国德克萨斯至阿根廷的美洲地区、非洲南部部分地区及大洋洲部分地区,欧洲及中国部分地区有引种。黄薇属目前共有5种分别是黄薇(Heimiamyrtifolia)、Heimiaapetala、Heimiasalicifolia、Heimialongipes、Heimiamontana。黄薇主要分布于南回归线附近南美洲的热带亚热带地区,南亚地区因人类的迁移而有零星分布。我国引种的黄薇属植物仅黄薇一种,引自巴西,上海、昆明、广州、杭州、桂林、漳州及台湾部分地区皆有引种栽培。黄薇与其他花木相比而言,花色鲜艳美丽,生长迅速,对环境适应力较强,耐粗放管理、维护较易,植株可塑性较好,在生态恢复、环境景观效果和药用上价值较好,应用和研究的前景广泛。黄薇为落叶丛生灌木,高1-2m;枝开展,纤细。单叶对生,间有互生或轮生,披针形,长达6cm,宽3-14mm,先端尖,基部渐窄狭, ...
