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Na3 VO4能促进草莓果实花青苷积累、降低可溶性总糖含量 。During strawberry ( Fragaria ananassa Duch cv.chunxing) fruits maturation,the content of total sugar,anthocyanin and respiration rate increased significantly,and Ca 2+ _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 Ca 2+ _ATPase was the highest in microsome membranes. Na 3VO 4,an inhibitor of plasma membrane Ca 2+ _ATPase activity,stimulated accumulation of anthocyanin,declined the total sugar content,but had different effects with various fruit mature degree.
