１９８６～１９９２年由澳大利亚提供史密斯桉种源１２个，亮果桉种源１７个，分别在保山、昆明、楚雄进行史密斯桉、亮果桉的种源选择试验。试验结果表明：史密斯桉、亮果桉存在种源差异；从生长量、生长稳定性、抗逆性、桉油含量等方面进行综合评定认为，史密斯桉１５５４４、１５０９２、１２１３１种源，亮果桉１２４０１、１３２８１、１４４４９、１６６３６、１６７５０种源是表现较好的种源，４～６年生史密斯桉优良种源，与直干桉对照相比，蓄积量的平均实际增益为５８％；而３～４年生亮果桉蓄积量的平均实际增益为７３％。史密斯桉含油量增益为５７．４％。试验选择出以上述两树种种源可在适宜地区推广。
From 1986 to 1992, 12 Eumyceton spp. Provenances and 17 Eucalyptus spp. Provenances were provided in Australia. The provenance selection experiments of Eucalyptus and Eucalyptus were carried out in Baoshan, Kunming and Chuxiong, respectively. The results showed that there was a provenance difference between Eucalyptus globulus and Eucalyptus globulus. According to the comprehensive assessment of growth, growth stability, stress resistance and eucalyptus oil content, 12401,13281,14449,16636,16750 kinds of provenances are good provenance provenances, 4 to 6 years old provenance Eucalyptus provenance, compared with the direct eucalyptus comparison, the average actual accumulation of volume gain of 58%; and 3 ~ The average actual gain of 4-year-old Eucalyptus stockpiles was 73%. Smith Eucalyptus oil gain of 57.4%. The test selected to the above two kinds of tree species can be promoted in the appropriate area.
