| Abstract: | Using principal component analysis,the cold resistance of 36 apricot cultivars was evaluated with the material of dormant shoots and 11 physiology and morphology indexes.Through the test,the resistance of 36 apricot cultivars was determined and sorted.The most cold resistant cultivars are:Longwangmao,Yinbaixing and Chuanzhihong and the most cold sensitive cultivars are:Zaohong,Laoshanhong and Honghebao.The equation which could measure cold resistance grades of apricot cv.was also found. |
