用电导法、冰点降低法、蒽酮和砷钼酸比色法及生长恢复试验法对11个牧草品种作了抗寒性鉴定。虽然这四种方法的指标都与温度极相关(P<0.01),但作者认为电导法和冰点降低法可行,其它三种方法不宜提倡。
The cold tolerance of eleven forage cultivars was identified by conductivity method, freezing point reduction method, anthrone and arsenic molybdic acid colorimetry and growth recovery test. Although the indices of these four methods are extremely correlated with the temperature (P <0.01), the authors believe that the conductivity method and the freezing point reduction method are feasible, and the other three methods should not be advocated.
