摘　　要：针对消费者反映温室番茄激素坐果风味差的问题,试验设计了3种坐果方式,即震动坐果、自然坐果和激素喷花坐果,测定了影响品质要素的果实中可溶性糖、淀粉、果糖、蔗糖和Vc含量。结果表明,番茄果径的生长速率是激素喷花坐果方式较高;糖含量中,激素喷花较震动和自然坐果方式果实的可溶性糖含量下降50%左右;第2,3穗果实中震动坐果、自然坐果均比激素坐果的淀粉、果糖、蔗糖和Vc含量高。震动坐果比自然坐果糖含量略高,可以认为与授粉效果较好有关,风味物质的增加是品质较好的内在要素,因此,震动坐果提高果实风味的效果较好。In view of the problem of poor taste of tomato fruit in greenhouse, three fruit-setting methods were designed, that isshaking fruit, natural fruit setting and hormone spray fruit setting. The contents of soluble sugar, starch, fructose, sucrose and Vc in thefruit which affected the quality factors were determined. The results showed that the growth rate of tomato fruit diameter was higher thanthat of hormone spraying. In the sugar content, the soluble sugar content of the fruit by hormone spraying was about 50% lower than thatof the shaker and the natural fruit-setting mode. The content of starch, fructose, sucrose and Vc in the fruit of the second ear and the thirdear were higher than that of the steroid fruit. The content of vibration was slightly higher than that of natural sugar, which could beconsidered to be related to better pollination effect. The increase of flavor is the internal factor of better quality. Therefore, the effect ofshaking fruit setting on improving fruit flavor is better.
