桉树26个种33个种源在云南的生长表现

Growth Performance of 33 Provenances Representing 26 Species of Eucalyptus in Yunnan

对海口林场26个桉树种33个种源26 a的树高、胸径、材积和耐旱性进行分析,结果表明:史密斯桉(15092、15059、15091)、本沁桉(14214)、巴吉桉(13286)、亮果桉(14012)、银顶纤皮桉(14840)、直杆桉(直local)和广叶桉(13349)等9个种源在昆明市海口林场表现较优,其中前6个种源还具有较强稳定适应性;9个种源均可作为南方地区桉树种质资源供应基地建设、科普教育基地建设及优良种源展示基地建设的优选树种。

Height, diameter at breast height, tree volume and drought tolerance to age 26 years of 33 provenances representing 26 Eucalyptus species in Haikou Forest Farm, Yunnan, were analyzed. The results showed that performance of 9 provenances – E. smithii （15092, 15059, 15091）, E. benthamii （14214）, E. badjensis （13286）, E. nitens （14012）, E. laevopinea （14840）, E. maidenii （local） and E. amplifolia （13349） performed well for all the key traits examined in Haikou Forest Farm, including 6 provenances with a strong stable adaptability. These 9 provenances should be able to serve as Eucalyptus germplasm resources for the development of the eucalypt plantation resources in southern China and will also be a useful resource for science education.
