摘要
果实采后品质与采收期密不可分,探究果实最适采收时间对果实的销售推广有较大的意义。本研究以‘盘克汉姆’为试验材料,探究不同采收期对果实品质的影响,从腐烂率、失重率、果实硬度、果皮色差、可溶性固形物含量、有机酸含量和维生素C等方面阐述不同采收期对果实采收及货架期品质的影响,以明确‘盘克汉姆’贮藏及销售最适采收期,提高果实的商品价值。研究表明:花后160 d采收的果实具备较长的货架期,但果实可溶性固形物含量和维生素C含量稍差于花后170 d采收果实。花后170 d采收的果实具备较好的果实色泽及风味,但货架期硬度低于花后160 d采收果实,果实后熟时间早于花后160 d采收果实。为满足长途运输需求或寻求更长的货架期可以选择花后160d左右采收,如果当地售卖可以在追求果实品质的情况下选择花后170 d左右采收。
The quality of fruit is closely related to its harvest time.Therefore,it is significant to determine the optimal harvest time for fruit commercial value.We used'Pankham'as the test material to explore the influence of different harvestingperiods on fruit quality,and expounds the influence of different harvest periods on fruit harvest and shelf life quality fromtheaspects of decay rate,weight loss rate,firmness,color difference,soluble solid content,organic acid content,and vitaminCcontent.The results showed that fruits harvested 160 days after flowering had a longer shelf life,but had slightly lower contents of soluble solid and vitamin C than those harvested 170 days after flowering.Fruits harvested 170 days after flowering had better color and flavor,but lower shelf life firmness than the 160-day fruits and ripened earlier.In order tomeet the needs of long-distance transportation or to seek a longer shelf life,we can harvest near 160 days after flowering;wecan harvest near 170 days after flowering for local sales.Clarifying the optimal harvest period for storage and sales of'Packham's Triumph',we can improve the fruit commodity value.
