摘要
以和田县骏枣为试材,分别于2014年10月7日、14日、24日、30日及11月7日进行采样,对样品的果实性状及主要品质指标进行了测定,研究了不同采摘期对和田骏枣品质的影响。结果表明:随着采摘期的推迟,和田骏枣的单果质量、果核质量、可食率、含水量均是先增加再减小;果实的纵横径与果核的纵横径变化趋势基本一致;维生素C含量不断降低,可滴定酸、总糖含量增加,这3个指标均在10月30日变幅显著。和田骏枣的含水量、可滴定酸、维生素C含量与总糖含量在采摘期内有显著性差异。综合和田骏枣的各项指标,认为10月24—30日为最佳的采摘期。
Hetian junzao was used as material,the effects of different harvest dates which were 2014 Oct.7th,14 th,24th,30 th,Nov.7th on fruit traits and main qualities of Hetian junzao were determined and ananlyzed.The results showed that fruit weight,kernal weight and edible rate,the content of water in Hetian junzao increased first and then decreased,fruit vertical and horizontal diameter and aspect of stone diameter changing trend were consistent,vitamin C content decreased,the contents of titration acid and total sugar increased,and significant difference on Oct.30 th.The contents of water,titratable acid,vitamin C and total sugar had significant difference in harvest period.The best harvest period of Hetian junzao were from October 24 th to 30 th.
