摘要
【目的】研究百香果冬季果实的生长发育及品质形成规律,为果实营养调控及采摘时机选择提供科学依据。【方法】以金都百香3号为材料,观察、测定其冬季果实发育过程中的纵径、横径、单果质量、果皮质量和果皮厚度、可溶固形物含量、可滴定酸含量、还原糖含量和维生素C含量等指标,研究果实品质相关指标的变化规律和品质形成关键时期;分析果实品质动态变化的相关性,评价冬季果实品质。【结果】金都百香3号冬季果实的果汁形成始于花后45 d,果汁变色始于花后50 d,果皮变色始于花后90 d,果实完全成熟自然脱落于花后130 d。果实纵径、横径、可食率和果汁率均呈先缓慢增长,然后迅速增长,最后逐渐趋于平稳的变化趋势,分别于花后25、30、110和110 d接近最大值并趋于稳定;单果质量在花后95 d达最大值;果皮的质量和厚度均在花后35 d开始下降,花后110 d后趋于稳定;可溶固形物含量与固酸比总体呈上升趋势,且果实完全成熟时达最大值;可滴定酸、还原糖及维生素C含量呈先增长后下降趋势,分别于花后80、120和110 d达最大值;金都百香3号冬季果实发育过程中可滴定酸的动态变化与还原糖、可溶固形物和维生素C含量呈负相关。【结论】金都百香3号冬季果实外观品质形成的关键时期为花后0~30 d和花后90 d至果实完全成熟;内在综合品质形成的关键时期是花后90~120 d;花后110 d为该品种冬季果综合品质表现最佳时间。
【Objective】This paper studied the growth,development and quality formation pattern of the winter fruit of Jindubaixiang No.3(JD3)passion fruit,so as to provide scientific guidance for fruit nutrition regulation and picking time selection.【Method】By observing and measuring the longitudinal diameter,transverse diameter,single fruit weight,peel weight,peel thickness,soluble solid content,titratable acid content,reducing sugar content and vitamin C content of JD3 winter fruit during each period of development,this paper studied the change rules of quality-related indicators and key period of quality formation;further analyzed and clarified the correlation between the dynamic changes of fruit quality and evaluated the quality of winter fruits.【Result】The juice formation of JD3 winter fruit began at 45 d after flowering.The juice discoloration began at 50 d after flowering.The peel discoloration began at 90 d after flowering.The fruit was ripe and shed naturally at 130 d after flowering.The fruit longitudinal diameter,transverse diameter,edible rate and juice rate of JD3 showed a trend of slow growth,then rapid growth,and finally gradually levelling off,and reached the maximum at 25,30,110 and 110 d after flowering respectively and remained stable.The single fruit weight reached the maximum at 95 d after flowering.The weight and thickness of peel began to decrease at 35 d after flowering and tended to be stable at 110 d after flowering.Total soluble solid content and the ratio of total soluble solid content to titratable acid content showed a rising trend in general,and reached the maximum at full ripening.The contents of titratable acid,reducing sugar and vitamin C increased at first and then decreased,reaching the maximum at 80,120 and 110 d after flowering respectively.The dynamic changes of content of titratable acid were negatively correlated with the contents of reducing sugar,total soluble solid and vitamin C during JD3 winter fruit development.【Conclusion】The key period for the appearance quality formation of JD3 winter fruit is 0-30 d after flowering and 90 d after flowering to full ripening of fruits.The key period for the internal comprehensive quality formation is 90-120 d after flowering.And 110 d after flowering is the best time for the comprehensive quality performance of JD3 winter fruits.
