摘要
选取种源来自于澳大利亚新南威尔士州、昆士兰州和维多利亚州的巨桉、邓恩桉、柳桉、亮果桉、史密斯桉、多利桉和巴吉桉共7个树种22个种源为试验材料,进行引种试验,34个月后对其生长指标与冻害等适应性指标进行调查。结果表明:参试材料中邓恩桉0612、邓恩桉99/01和多利桉97/06等3个种源的适应性较强,冻伤轻微,冻害等级为Ⅰ;邓恩桉0612、邓恩桉99/01适合赣南引种种植;但多利桉97/06生长量相对较低,应先进行引种驯化,再根据驯化情况及实际需要决定是否推广种植。
Selected provenances of E. grandis, E. dunnii, E. saligna, E. nitens, E. smithii, E. dorrigoensis and E. badjensis alto- gether 7 species which including 22 provenances as the test material from New South Wales, Queensland and Victoria in Australia. The introduction and testing based on 34 months on the growth index and frost damage adaptive index survey. The result showed that： E. dunnii 0612, E. dunnii 99/01 and E. dorr/goens/s 97/06 a total of 3 strains/seed lots have stronger adaptability, the level of damage to lesser extent, for Grade I.E. dunnii 0612 and E. dunnii 99/01 are suitable for introduction and cultivation in southern of Ganzhou city, but the growth of E. dorr/goens/s 97/06 is relatively low, we must carry on the introduction and domestication, and decide the strain/provenance is suitable for planting or not.
