南美蟛蜞菊的繁殖研究

Study on the propagation of Wedelia trilobata Hitchc

南美蟛蜞菊是耐荫的草本植物,因其具有良好的覆盖力,并能有效抑制异种植物的生长,被广泛应用于园林绿化工程中.通过用南美蟛蜞菊的种子和茎段进行繁殖试验,结果表明:播种繁殖发芽率为零,而扦插繁殖在不同温度和光照条件下其生长有较大差异.在温度较高时和充足的光照下植株一般生长较好.

Wedelia trilobata Hitchc is the shade - enduring herbaceous plant. It can cover the ground well and restrain other category plants＇ growing effectually, so it is widely used in landscaping. From the experiment of propagation with Wedelia trilobata Hitchc＇ s seeds and cuttings, it shows that the germinated - ratio of propagation with seeds is zero and the reproduce - ratios of propagation with cuttings under different temperature and sunshine conditions are much difference. The plants grow better on appropriate temperature and adequate sunshine than the other conditions.
