设施大樱桃果实发育过程中主要营养成分含量变化的研究

为了明确设施大樱桃在果实发育过程中营养成分含量的变化规律，以“红灯”为试材，对设施大樱桃发育中果实可溶性固形物、维生素C及果实硬度进行了研究。结果表明：随着果实的生长，可溶性固形物含量呈增加趋势；维生素c含量呈“升-降”的动态变化，授粉后35d，维生素C含量达到最高值；果实硬度则呈逐渐下降趋势，授粉后42d左右果实硬度下降至最低点。为了保证果实品质，建议在生产上可将授粉后的35-42d作为判断果实成熟度的拳考指标。

Research on the Change of Major Nutrient Content on Facilities Cherry during the Development

In order to clarify the variation of nutrient content on facilities cherry during fruit development, the experiment with red light as material studied the soluble solids ,vitamin C and fruit firmness in facility cherry. The results show that：with the growth of the fruit, the soluble solids content showed an increasing trend; Vitamin C content was the dynamic change of ＂up-down＂, 35 days after pollination,the Vitamin C content was the highest value;fruit firmness decreased gradually,about 42 days after pollination,fruit firm- ness was under the bottoming out. So in order to ensure fruit quality, it is recommended to be 35-42 days after pollination as a reference indicator of determine fruit maturity in production.
