1982年1月在马拉维钦泰切地区的Litende建立了尾叶桉地理种源试验。5年结果评价表明地理种源中的植株胸径、材积、树皮厚度和木材密度有显著差异。生长与木材密度变异性表明地理种源与植株选择方法可用于尾叶桉遗传改良。试验肯定了钦泰切地区尾叶桉的快速生长。4个最好的地理种源是来自阿洛岛西部、勒沃托比山、潘泰岛东北和Mandiri山的,宜推荐在本地区发展;在马拉维建立遗传资源保留林分和人工试验林可采得这些种源的尾叶桉种子。
In January 1982, a geo-provenance test of Eucalyptus urophylla was established in Litende, in the Qintai region of Malawi. Five-year results showed that there was a significant difference in plant DBH, volume, bark thickness and wood density in geographic provenance. Growth and wood density variability indicate that geographical provenance and plant selection methods can be used for genetic improvement of Eucalyptus urophylla. The experiment affirmed the rapid growth of Eucalyptus urophylla in the Qintai region. The four best geographical provenances are those from western Alor, Lewotobi, Pentai Island, northeast and Mandiri Hills and should be recommended for development in the region; establishment of a reserve of genetic resources in Malawi and artificial trials Lin can take these provenances of Eucalyptus urophylla seeds.
