| 摘 要： | 对第1代引种尾叶桉种源家系试验及在第1代种源家系试验基础上遗传选优建立的第2代尾叶桉实生种子园的开花结实信息做了总结。第1代和第2代尾叶桉种源家系试验均显示,引种后尾叶桉花期与原产地花期有很大的差异,这可能是地理变异和气象条件差异的结果。引种后尾叶桉果实成熟期也存在较大的变异。

| Abstract: | It was summarized that florescence and seeding in first generation test of provenances and families of introduced E.urophylla and the second generation E.urophylla seed orchard which was established from good provenances and families of the first generation.The results showed that the florescence of the first and second generation tests of provenances and families of E.urophylla had both significant differences to original habitat,maybe this was caused by the variation of geography and climate.Meanwhile,see... |
