| 摘 要： | 应用灰色关联度系统理论,通过干草产量、株高、茎叶比、再生速度、总叶绿素含量下降率、叶片相对电导率上升率、根系相对电导率上升率、侧根长、主根长、根系生物量等性状指标对12个紫花苜蓿品种的生产性能进行了综合评价。结果表明:干草产量和综合性状最好的品种是‘海盗’;‘超级7号’、‘昆德拉’和‘三得利’次之;‘山锐’和‘阿尔冈金’干草产量和综合性状最差,不适宜在川西南地区种植。

| Abstract: | The productive performance of 12 Medicago sativa cultivars was evaluated by gray systematic theory in hay yield,plant height,stem/leaf,regeneration rate,decrease rate of the total chlorophyll content,increase rate of the relative electric conductivity,length of taproot,length of lateral root and root biomass.The results showed that 'Pirate'was the best on the whole and had the highest hay yield,followed by 'Super7','Sanditi' and'Quadrella'.The yield and comprehensive characteristics of 'Paramount' and 'Algonquin'were the worst and they were unsuitable to be planted in Southwest of Sichuan Province. |
