中文摘要：

以红富士苹果（Malus domesticaBorkh.cv.‘Red Fuji’）为试材,研究了发育过程中以及成熟后期套袋果实Ca2＋-ATPase的活性变化。结果表明,发育初期,苹果果实的Ca2＋-ATPase活性较高,随着果实生长发育,Ca2＋-ATPase活性逐渐下降,在发育后期Ca2＋-ATPase活性有所提高。与对照相比,套袋红富士苹果果实Ca2＋-AT-Pase的活性呈现先降低后升高又降低的变化趋势。发育后期,摘除果袋后苹果果实的Ca2＋-ATPase活性与对照相比有显著增加。与对照相比,套袋降低苹果果实的Ca2＋浓度。由此表明,套袋可能通过影响钙素的吸收运转和Ca2＋-ATPase活性而调控苹果果实的生长发育和品质形成。

英文摘要：

The changes of Ca2＋-ATPase in bagging fruit during fruit development and mature period were studied with ＇Red Fuji＇ apple（Malus domestica Borkh.cv.＇Red Fuji＇）.The results showed that the activity of Ca2＋-ATPase was high at the initial stage of fruit development,and then declined with fruit developing.However,the activity of Ca2＋-ATPase increased in a certain extent at the late period of fruit development.The activity of Ca2＋-ATPase in bagging apple fruit also indicated change tendencies of decline at first and then increase and drop again during the whole development period.The results showed that the activity of Ca2＋-ATPase in bag-removed fruit increased in the later growth stage compared with bagging fruit.Moreover,fruit bagging reduced Ca2＋ concentration compared with control.It is concluded that bagging regulated fruit development and quality formation through affecting the absorption translocation of calcium and the activity of Ca2＋-ATPase.
