5个草莓品种果实品质的比较研究

通过对5个草莓品种的果实外观品质和营养成分的比较研究,结果表明,红颊草莓果实大而美观,香味浓,口感好,品质佳;在经济性状上优于其他4个品种,硬度适中,耐贮运性好,是当前温室草莓栽培中较为理想的优质大果型品种。童子一号和玫瑰草莓果实营养成分上无显著差异,但在耐储运性上,童子一号果实硬度较低,不利于远距离运输,而玫瑰果实硬度达到了4.00Pa/cm2,耐贮运性好,在实际栽培过程中应结合实际情况加以选用。丰香草莓果实光泽强,香气浓,酸甜适中,平均单果重为20.29g,可溶性固形物、蛋白质、糖、酸和VC含量上在5个品种中处于中间位置,但其果实硬度最低,只有2.53Pa/cm2,耐储运性最差,适宜在当地自产自销。
