对很多马铃薯种、杂交种和栽培品种的耐寒水平已经有过报道(Li,1977;Richardson等,1972),多数是根据实验室测定的结果。在实验室里,为割下的叶子提供冰核防止过冷,然后使它们处于各种零下温度(Sukumaran和Weiser,1972)。然而,这不能准确地反映出马铃薯在田间条件下的抗
Cold tolerance has been reported for many potato, hybrid and cultivars (Li, 1977; Richardson et al., 1972), mostly based on laboratory measurements. In laboratories, the milled leaves are provided with ice cores to prevent overcooling and then left at various sub-zero temperatures (Sukumaran and Weiser, 1972). However, this does not accurately reflect potato resistance in the field
