Abstract:

Using the methods of electrical conductivity to mensurate the changes in cell electrolyte leakage rate (ie electrical conductivity) of 5 sweet cherries and 1 sour cherry’s branches after the process of continuous cold stress, the cold resistance of 5 varieties of sweet cherry were studied.The results showed that after the process of -20℃ low temperature continuous cold stress,the cell electrolyte leakage rate of all the cherries’ branches first increased and then decreased.When the cell undergo the cold stress with the temperature near the critical lethal,the cell’s self-recovery capability would rapidly improve in a certain of short period of time.Compared the relative values of cell electrolyte leakage rate between species and analyzed the condition of cell self-derived capability,a conclusion was got,sour cherry ‘CAB’,cold resistance of ‘Hongyan’ and ‘Longguan’ was relatively strong,they were varieties with a stronger cold resistance,‘Hongmi’, cold resistance of ‘Hongdeng’ and ‘Moli’ was relatively weak,they were varieties with a weaker cold resistance.
