Abstract:
‘Hanfu’apple and its parents (‘Dongguang’בFuji’) were used to study shoot cold tolerance through measuring electric conductivity under artificial low-temperature stress.The results showed that shoots electric conductivity of ‘Hanfu’ apple and its parents increased as decrease of cold temperature,with insignificant differences〖KH-1D〗 among three apple cultivars.The semilethal temperatures of ‘Hanfu’ apple,‘Dongguang’ and ‘Fuji’,calculating by Logistic equation,were -43.3,-45.3,-37.5℃,respectively.In conclusion,cold tolerance of ‘Dongguang’ apple was the strongest,‘Fuji’ apple was the weakest，and ‘Hanfu’ was the middle one.
