非洲破布木是埃塞俄比亚的本土商业木材树种,在自然种群中,存在着巨大的品种变异。由于当地苗圃优良种质资源匮乏,筛选优良母树建立种子园非常必要。该研究从其不同的自然种群中,采集了大量的供试种子样品,对其种子外部特征和在苗圃中发芽率和种苗生长表现,进行了观察;方差分析显示,在所有的研究属性中,不同种源显示出较大的属性差异性,同时初步筛选出适合种子园所需的优树。
African ragweed is Ethiopia’s native commercial timber tree species and there is a huge variety of variation among natural populations. Due to the lack of excellent germplasm resources in local nurseries, it is very necessary to select good mother trees to establish seed orchard. In this study, a large number of tested seed samples were collected from different natural populations and their external characteristics of seeds and germination rate and seedling growth performance in nursery were observed. An analysis of variance showed that among all the research attributes , Different provenances show a greater difference in properties, while screening for the initial seed tree for the tree you need.
