| 摘 要： | ‘春星’草莓果实成熟时，总糖和花青苷含量增加，呼吸速率也显著升高；同时，细胞溶质Ca2+-ATPase活性和微粒体膜的Ca2+-ATPase总活性变化具有相似的特点，即先升高，至粉红期达到高峰，全红期又下降，在微粒体膜中以质膜Ca2+-ATPase占的比例最高。抑制质膜Ca2+-ATPase活性的Na3VO4能促进草莓果实花青苷积累、降低可溶性总糖含量，但对呼吸速率的影响则因草莓果实成熟度不同而异。

| Abstract: | During strawberry （Fragaria ananassa Duch cv.chunxing）fruits maturation，the content of total sugar，anthocyanin and respiration rate increased significantly，and Ca2+-ATPase activity of cytoplasm and microsome membrane increased firstly，then peaked at pink stage，and decreased at full red stage in fruits，and also，the activity of plasma membrane Ca2+-ATPase was the highest in microsome membranes. Na3VO4，an inhibitor of plasma membrane Ca2+-ATPase activity，stimulated accumulation of anthocyanin，declined the total sugar content，but had different effects with various fruit mature degree. |
