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。
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.
