荷兰菊属(Aster)植物是我国北方优良、耐寒宿根花卉,为北京及广大北方城市国庆节主要观赏花卉之一,也是城市大面积美化的好材料品种很多。其繁殖方法一般为扦插繁殖和分株繁殖。为了配合优株的选育及迅速将优良单株大量繁殖,我们对三个新品种进行了快繁工作,实践证明这确实是一条切实可行的方法。 Aster is an excellent and cold-tolerant perennial flower in northern China. It is one of the major ornamental flowers in Beijing and the northern cities of China during the National Day. It is also a good variety of urban landscaping materials. The breeding method is generally cutting propagation and ramets breeding. In order to cooperate with the breeding of superior plants and quickly multiply the fine single plants, we conducted the fast propagation work on three new varieties. Practice has proved that this is really a feasible method.
