建立采穗圃是为了提供大量的优树种条,营造无性系种子园或直接用于无性系育苗造林,是实现油茶生产良种化的关键性措施之一。搜集分散在各地的油茶优树选定适当地建立区(省)一级中心采穗圃,不仅有利于优树的采集和繁育,还可兼具优树基因库的功效。为此,选定临桂凤凰林场建立全区油茶中心采穗圃兼优树基因搜集库和当代鉴定圃。实行“边选择,边鉴定、边繁育”,结合嫁接改冠试验组织协作攻关,三年来初见成效。
It is one of the key measures to realize seed production of Camellia oleifera in order to provide a large number of excellent tree species, to create a clonal seed orchard, or to use directly for clonal nursery and afforestation. It is not only good for collecting and breeding elite trees, but also for optimizing the gene pool of elite trees. To this end, Lin Feng Phoenix forest selected the establishment of the whole area tea garden scion and yucca gene pool and contemporary identification of nursery. The implementation of “edge selection, edge identification, edge breeding”, combined with grafting experiment to improve the organization collaborative research, three initial results.
