摘　　要：新品种繁育是未来观赏水生植物发展的一个重要方向,选育性状优良、造景可塑性强、拥有自主知识产权的观赏水生植物新品种,是我国观赏水生植物产业发展的必由之路。研究以芭特水榕(Anubias barteri)为亲本,从其组培繁殖群体中通过单株选育再经组培快繁而成。新品种碧玉水榕株高12.6 cm,株幅17.3 cm,主茎半直立,叶片数20.6片,叶片椭圆形,深绿色,比对照品种芭特水榕株型更紧凑,叶片更小,分蘖性、抗逆性更强,在小于60cm的水族缸中可做主景使用,在更大的水族缸中可用于中景或点缀用。以去茎尖后新萌发的腋芽为外植体进行组培快繁生产组培苗,以岩棉为基质进行水培栽培,定时叶面喷雾保湿、供肥,栽培300 d左右即可成苗出货,成品植株放置于水族缸中适应水质后拆掉岩棉清洗干净即可进行造景应用。The breeding of new varieties is an important direction for the development of ornamental aquatic plants in the future.It is the only way for the development of ornamental aquatic plant industry in China to select new varieties of orna-mental aquatic plants with excellent traits,strong plasticity and independent intellectual property rights.With Anubias barteri as parents,it was obtained from the tissue culture breeding population by single plant selection and then rapid propagation by tissue culture.The new Anubias barteri variety‘Biyu’has a height of 12.6 cm,crown width of 17.3 cm,semi-erect main stem,20.6 leaves,oval shape,dark green leaves.Compared with the control variety,the plant type is more compact,the leaves are smaller,and the tillering and stress resistance are stronger.It can be used as the main scene in the aquarium tank less than 60cm,and can be used as the middle scene or decoration in the larger aquarium tank.Tissue culture and rapid propagation were carried out to produce tissue culture seedlings using the newly germination axilla buds after removal of stem tips as ex-plants,and hydroponics were carried out with rock wool as the substrate.The leaves were regularly sprayed to moisturize and fertilized.The seedlings could be produced and shipped after about 300 d of cultivation,and the finished plants were placed in the aquarium tank to adapt to the water quality,and then the rock wool was removed and cleaned before landscape application.
