| 摘 要： | 对22份澳大利亚引进牧草种质进行试验评价，通过对产量、株高、长势、存活株数、分枝分蘖数、萌发能力、病级和虫级等指标的测定，并利用灰色关联度分析与主成分分析法综合评价其适应性，结果表明，各参试牧草中，产量最高的为俯仰臂形草Brachiaria decumbens、卡松古拉狗尾草Setaria anceps Kazungula、湿生臂形草B. humidicola、坚尼草Paspalum maximum、珊状臂形草B. brizantha Mekong、卡琳达罗得虎尾草Chloris gayana PIONEER Rhodes和甘巴草Andropogon gayana GAMB；综合评价中，适应性最强的牧草为坚尼草、俯仰臂形草、甘巴草、卡松古拉狗尾草。

| Abstract: | The yield,plant height,vigor,survival rate,branching and tillering,germination,disease and pest resistance of 22 herbaceous forage germplasms introduced from Australia were measured to comprehensively evaluate their adaptability by using gray mathematical statistical methods and principal component analysis.The results showed that the yields of Brachiaria decumbens,Setaria anceps,B.humidicola,Panicum maximum cv.Mombassa,B.brizantha,Chloris gayana and Andropogon gayana were higher than the other varieties an... |
