优良野生花卉牛耳岩白菜的品种选育

The Variety Breeding of a Fine Wild Flower:Chirita eburnea Hance

通过多年的调查引种和驯化栽培,发现牛耳岩白菜有5个变异株型,即长叶白、长叶紫、圆叶平、圆叶紧和长叶紫紧牛耳岩白菜,对这5个实生变异株进行了盆栽观赏性状比较观察,发现圆叶紧、长叶紫紧牛耳岩白菜无论在株型、花色、花形及花期等方面表现出明显的优势,最适合园艺盆栽观赏应用;而长叶白牛耳岩白菜各方面观赏性状较差,建议淘汰;长叶紫和圆叶平牛耳岩白菜各方面观赏性状表现中等,可根据喜好适当发展应用。

Through years of investigation,introduction and domesticate cultivation,five variances of Chirita eburnea Hance have been found,namely,long leaf white,long leaf purple,round leaf flat,round leaf tight,and long leaf purple and tight.Through a comparative observation of bonsai＇s ornament characters on the five variances,the following conclusions are drawn：round leaf tight and round leaf purple and tight,has obvious advantages no matter in plant type,color,shape or flowering and are most suitable for horticulture;the elimination of long leaf white is proposed due to the relatively poorer performance on ornamental characters;long leaf purple and round leaf flat could be moderately developed and applied according to preferences because of their mediocre performance in ornamental characters.
