摘要
比较了桉树7个品系在3个不同海拔的成活率、耐寒性、抗虫性、树干弯曲程度和径高比5个性状。结果表明:不同品系的耐寒性、抗虫性、树干弯曲程度、径高比存在显著差异,海拔高度对成活率、耐寒性、树干弯曲程度、径高比具有显著影响;多重比较结果表明:比较适宜闵东发展的桉树品系是尾赤桉201、其次是尾巨桉3229和尾圆桉184。
5 traits including survival ratio, cold resistance, insect resistance, stem form and the ratio of diameter to height were compared among 7 varieties of Eucalyptus from 3 locations of different elevation in Yongtai County, Fujian Province. The experimental plantations were established on a design of random block with 3 repetitions. The results of two factors variance analysis indicated that there was a significant difference existing among varieties for these traits like cold resistance, insect resistance, stem form and the ratio of diameter to height. Elevation had remarkable effects on survival ratio, cold resistance, stem form and the ratio diameter and height ratio.3 varieties, Eucalyptus urophylla x camaldulensis 201, Eucalyptus urophylla x grandis 3229 and Eucalyptus urophylla 184, were selected to be potential varieties for afforestation in Yongtai County.
