【摘要】 以可溶性糖、维生素C、可溶性固形物、番茄红素、有机酸为指标,分别测定乌兰乌苏、炮台和沙湾3地"异地分期种植"番茄中的含量,并搜集相应的气象资料,通过相关分析和通径分析研究坐果-成熟期光温因子对番茄品质的影响。结果表明:除日照时数和相对湿度外,其他气象因子对加工番茄品质均有一定的影响。对番茄红素含量影响起直接作用的是≥15℃有效积温和日均温度,对可溶性固形物含量影响起直接作用的最高温度和日均温度,对Vc含量直接作用较大的是日均温和≥15℃有效积温,对可溶性糖含量直接作用较大的是最低温度和日温差,对有机酸直接作用较大的是最低温度、日温差和最高温度。更多还原

【Abstract】 The content of stage planting tomato in three different places of Wulanwusu,Paotai and Shawan were determined based on the indexes of soluble sugar,vitamin c,soluble solid,lycopene and organic acid.By collecting the relevant meteorological data,the impacts light-temperature factors of maturity fruit setting on quality of processing tomato in Xinjiang were studied through path analysis and correlation analysis.The results showed that all meteorological factors had effect on processing tomato fruit quality except sunlight time and relative humidity.Total effective temperature accumulation above 15℃ and daily mean temperature showed more effects on lycopence,maximum temperature and daily mean temperature had the more direct effect on soluble solid content,daily mean temperature and temperature accumulation above 15℃ had the more direct effect on vitamin c.minimum temperature and daily temperature difference had the more direct effect on soluble sugar content,minimum temperature,daily temperature difference and maximum temperature had the more direct effect on organic acid.更多还原
