闽南山地粗皮桉家系引种试验

Introduction Experiment of Eucalipu pellida Family in South Fujian

在闽南山地开展粗皮桉139个家系引种试验,结果表明:参试的家系基本能适应闽南的立地和气候条件,但不同家系间的生长量、干形、适应性等差异显著。采用坐标综合评定方法对不同家系的生长指标、保存率、干形和冠体积等因子进行综合分析评价,选出57、58、92、152、67、76、23、64、180、87、19、136、187、95、115、8、33和11号等18个家系属于优良家系,其生长量大、长势旺盛、树干通直、树冠匀称,冠体积大,可进一步引种栽培,也为今后开发利用提供基因资源。

Introduction experiment of 139 families was conducted in south Fujian, different family basic could adapt the local site and climate conditions, however, significant difference existed between different family growth, stem form, and adaptability. Compre- hensive assessment of the use of coordinates of different families of growth parameters, survival rate, stem form and crown volume factors were analyzed and evaluated,57, 58,92,152 ,67, 76, 23, 64, 180, 87, 19, 136, 187, 95, 115, 8, 33 and 11 family were selected and grew well, had big growth volume, straight trunk, symmetrical crown, and big volume of crown, which could be cultured further for providing genus resource for future development and utilization.
