摘　　要：在永安开展耐寒桉树21个树种53个种源引种试验,通过对参试树种/种源存活率、树高、胸径、材积等生长指标和适应性,以及耐寒、抗病虫害等抗逆性的调查,经综合评选,结果表明:适合福建省中亚热带山地发展的优良耐寒桉树树种是巨桉(E.grandis)、邓恩桉(E.dunnii)、柳桉(E.saligna)、本沁桉(E.benthamii)和道里格白桉(E.dorrigoensis),优良种源巨桉为20261、19971、18139、20116和18146号,邓恩桉是18264、15956、18263、20632、和20633号,柳桉是19667、19106、19453、18162和18988号,本沁桉是19282和18788号、道里格白桉是18763和19668号种源,共计5个树种19个种源。A cold-tolerant eucalyptus species and provenance trial established in northwestern Fujian province including 53 provenances within 21 species in 2003 were reviewed,Results confirmed the feasibility of five successful species and 19 provenances in semi-subtropical areas of YongAn in Fujian province.Species such as E.grandis,E.dunii,E.saligna,E.benthamii and E.dorrigoensis grew well and were most cold-tolerant.The best growth performance of E.grandis was 5 provenances of seedlots 20206,19971,18139,and 18264.There were better provenances of E.dunii 18264、15956,18263,20632,and 20633 seedlots and E.saligna 19667,19106,19453,18162,and 18988 seedlots;E.benthamii 19282,18788,18763,and 19668 seedlot;and E.dorrigoensis 18763 and 19668seedlots.
