摘要
以草莓“宝交早生”为试材，对果实成熟过程中的生理生化特性进行了研究。结果表明，草莓成熟过程中，呼吸作用、乙烯释放率、纤维素酶活性和细胞渗透性均逐渐增强，说明成熟度越高，果实的生理代谢活性越强，变质软化的速度也加快；另一方面，果实的花青素含量、营养成分不断积累，说明草莓果实的色泽和营养成分也与成熟度密切相关。综合分析认为，草莓适宜的最佳采收期为着色面积在３／４至全红之间。
The physiologic and biochemical changes of 'Baojiao Zhaosheng' strawberry were studied during maturation. The results showed that: (1)the respiration, ethylene production rate, cellulase activity and permeability of cell increased gradually with the rising of maturation of furit; (2)the amount of anthcyanidin and nutrient components also acumulated with the rising of maturation. After analysing comprehensively, suggested that the optimum harvesting time of strawberry was that the red aera was between 3/4 and 100 % of the whole fruit.
