[目的]研究品种及种植时间对早春大棚番茄果实大小整齐度的影响，为探索早春抗逆栽培技术和番茄果实商品果分级提供理论依据。以不同品种和不同栽培时间研究早春塑料大棚番茄的果实整齐度。[结果]早春番茄果实次果率和果实大小整齐度受品种和环境影响较大，在33个测试番茄品种中采收前期果实次果率最高可达98％，最小6％；果实大小整齐度较好的品种商品率达50％以上，整齐度差的品种商品性不足20％。[结论]同一种植时间果实次果率采收前期高于中期，但同一采收期间不同种植时间次果率没有显著差别。种植时间与采收时期都对果实整齐度没有显著影响。%Objective] To study the impacts of variety and planting time on fruit uniformity of tomatoes in a greenhouse in early spring to pro-vide theoretical foundation for exploration of stress-resistance cultivation technology and classification of commodity fruits of tomatoes.[ Meth-od] The fruit uniformity of different varieties of tomatoes planted on various dates in early spring in a greenhouse was studied.[Result] The rate of inferior fruits and fruit uniformity of tomatoes in early spring were influenced by variety and the environment obviously .In the early har-vest time, the highest rate of inferior fruits of the 33 varieties of tomatoes reached 98%, while the lowest rate was only 6%; the commodity rate of the varieties with good fruit uniformity was up to above 50%, while the commodity rate of the varieties with poor fruit uniformity was lower than 20%.[ Conclusion] The rate of inferior fruits of tomatoes planted in the same time was higher than in the early harvest time than that in the middle harvest time, but there were no significant differences between tomatoes planted on various dates in the rate of inferior fruits in the same harvest time.The planting time and harvest time had no significant effects on the fruit uniformity of tomatoes.
