Abstract: Slices of ‘Fuji’apple fruit which was stored at 0 - 4 ℃ for 1 month were treated with different concentrations of CaCl2 to evaluate the influence of exogenous Ca2+ on changes of their ethylene productions. The results showed that Ca2+ enhanced the ethylene production when CaCl2 concentrations were lower than 350 mmol·L-1, while it inhibited the ethylene production when Ca2+ concentration was higher than 350 mmol·L-1. During 0 - 12 h period of treatment , lower level of Ca2+ (80 mmol·L-1) produced more ethylene continuously , while the higher level of Ca2+ (500 mmol·L-1) inhibited ethylene production steadily. Not only low concentration of Ca2+ is a factor of cation to stimulate ethylene production , but Mg2+ and Mn2+ also showed the similar effect as Ca2+ did. La3+ (the inhibitor of Ca2+) and trifluoperazine (the inhibitor of CaM) inhibited ethylene production in the presence of low Ca2+(80 mmol·L-1) treatment .
