摘要
为了弄清草莓的果实生长发育规律以及营养成分的变化动态规律,本试验以达赛莱克特、石莓4号、石莓5号和石莓6号为试材,研究了草莓果实从谢花后3d到成熟果实生长发育规律和主要营养成分的变化规律。结果表明:果实纵横径在整个生长发育过程中一直是平稳增长;不同品种果实重量和体积均在花后15d左右开始迅速膨大;含糖量在草莓果实发育过程中总体上呈上升趋势,从白果期至成熟迅速增加;果实白果前可滴定酸呈增长趋势,白果期后开始下降;在果实的发育过程中维生素C含量表现出上升的趋势,至转红期达到最大,成熟时略有降低。
In order to ascertain growth developmental rule of strawberry fruit and dynamic rule of the nutrition ingredient change,the experiment material are Daselect,shimei 4,shimei 5 and shimei 6.It was studied that fruit growth developmental rule and rule of the nutrition ingredient change from flower latter 3 days to fruit mature.The result showed that the fruit length and width continuously is steadily growing during the whole growth developmental process;The fruit weight and the fruit volume of different culvars fast grows after flowers latter 15 days;The sugar content assumes the rising tendency in the overall during the strawberry fruit growth process;The acid content starts to increase from flower latter 3 days,and achieves biggest to half red period,then begin to drop in mature period;vitamins C content continuously increases from the young fruit period to the mature period,but the vitamin C content achieves the maximum value on turing red period,maturing period drops a little.
