摘要
通过采用木麻黄优树选择与子代测定的方法,从63个木麻黄家系中筛选出10个优良家系,再经苗期测定选出4个无性系在木麻黄更新造林中应用表明,其造林成活率、保存率和生长量以及抗病性均明显优于对照的木麻黄实生苗;综合抗风力、水培生根率和干形等评价指标表明,选育的粤501、平18、惠1和莆20等4个木麻黄无性系较为优良,可以在全省沿海防护林建设中推广应用。
Through adopting the method of progeny test and superior tree selection of Casuarina equisetifolia, 10 genealogies were selected from 63 genealogies. The application of 4 clones selected by nursery testing showed that the survival ratio, preserving ratio, growth and disease resistance were markedly superior to the tree seedling of Casuarina equisetifolia. The four surperior clones (Yue 501, Ping 18, Hui 1 and Pu 20) were selected according to wind resistance, hydroponics rooting rate and stem form, and could be popularized and applied in coastal protection forest construction of the whole province.
