Abstract:
‘Shushanggan’ is an unique apricot resource in Ili river valley.In order to study the cold hardiness on low temperature stress of ‘Shushanggan’ apricot,and the fitting cultivating region in Ili river valley.Conductivity method was used to observe the changes of leakage ratio of electrolyte (REC) after low-temperature treatment for investigating three varieties of apricot annual branch semilethal temperature (LT50).The results showed that,electrolyte leakage rate increased like ‘S’ curve when the temperature was reducing.At the same time combined with cold injury classification and recovery growth after low-temperature treatment,the semilethal temperature of ‘Shushanggan’ apricot was from -26 ℃ to -28 ℃.The order of cold tolerance was the big fruit ‘Shushanggan’ apricot>small fruit ‘Shushanggan’ apricot>precocious ‘Shushanggan’ apricot.According to the freezing injury classification,‘Shushanggan’ apricot was safe in the Ili temperature inversion area in winter.It should not be planted in flat area.
