摘　　要：为了研究黑莓的生长发育规律,指导黑莓的栽培管理与加工利用,在黑莓果实发育期,选用优良品种Boysen,采用随机标记和定期取样的方法,按照相关测定标准,调查果实不同发育时间的质量和主要营养物质的含量。结果显示:果实质量、可滴定酸、维生素C和维生素E累积量变化曲线为单S形,累积速率变化曲线为双S形;还原糖、总糖和花色苷的累积量和累积速率的变化曲线都为单S形。经统计分析发现:在果实发育的最后10 d,果实质量和主要营养物质的累积量均在50%以上,说明黑莓果实质量和主要营养物质的积累主要集中在果实发育的后期。The blackberry cultivar Boysen was chosen to study the growth and development regularity of blackberry fruit and to provide scientific basis of blackberry cultivation and utilization.The fruits were marked randomly and sampled at regular intervals,and fruit weight and main nutritional components were determined during fruit development period.The change of cumulants of fruit weight,titratable acid,vitamin C and vitamin E were shown as single S curve,while those of accumulation rates were shown as double S curve.The change of cumulants and accumulation rates of reducing sugar,total sugar and total anthocyanin were all shown as single S curve.According to the statistical analysis,the cumulants of fruit weight and main nutritional components in the last ten days accounted for over 50% of the total cumulants.It indicated the accumulation of fruit weight and nutritional components mostly happened during late development period.
