| 摘 要： | 以在北京试种成功的5种常绿阔叶树木为材料,以普通大叶黄杨为对照,测定多项水分生理和光合生理指标,探索以多指标综合评价常绿阔叶树木树种间及树龄间的抗旱差异,并对其抗旱能力进行主成分分析及按抗旱力大小进行排序和分类。结果表明:常春藤京8号2龄树木和荚迷抗旱力最强为第一类,常春藤京8号1龄树木和常春藤京9号2龄树木、京10号2龄树木为第二类,日本北海道大叶黄杨树和普通大叶黄杨为第三类。树种间抗旱性排序为荚迷>常春藤>大叶黄杨。同一树种不同栽培品种间排序为常春藤京8号>常春藤京9号>常春藤京10号。

| Abstract: | The five evergreen broad-leaved trees with successful plant experimentally in Beijing were selected as the material,the normal Euonymus japonicus was chosen as the control,the multinomial water physiology and photosynthetic physiology indices were determined with the application of some testing methods based on the different adaptation methods to drought stress of evergreen broad-leaved forests,the drought resistance difference was explored between the strain and the age of evergreen broad-leaved forests with the application of multi-indices comprehensive evaluation,the order of drought resistance ability was arranged and classified with the principle components analysis.The results showed:the two-year old Hedere helix JingNo.8 and Viburnum rhyliodophyllum were regarded as the first kind with the strongest drought resistance ability,the one-year old Hedere helix jingNo.8,the two-year old Hedere helix jingNo.9 and JingNo.10 were regarded as the second kind,the two-year old Euonymus japonicus and the normal Euonymus japonicus were the third kind.The order of the drought resistance among different strains was Viburnum rhyliodophyllum>Hedere helix jing>Euonymus jgaponicus and that of different cultivated varieties in the same strain was Hedere helix JinNo.8>Hedere helix JingNo.9>Hedere helix JingNo.10,Euonymus japonicus>the normal Euonymusjaponicus. |
