加工番茄产量构成因素分析

Analysis on Yield Component Factor of Processing Tomato

以加工番茄品种里格尔87-5和Q-027为试材,对两个品种的生长发育进程、产量构成因素、果实结果等方面进行研究。结果表明,这两个品种的果形均为长圆形;生长发育进程基本一致;第4、5、6花序的结果数相对其他花序要多,而且果实质量也相对其他花序高,是构成产量的主要因素。这一时期是加工番茄形成产量的重要时期,在这期间加强水肥及田间管理有望获得高产。

Selected processing tomato cultivars Liger87-5 and Q-027 as materials, development process, yield component factor, fruits spatial distribution and other aspects of the two cuhivars were studied. The research results showed that the fruit shape of both the two varieties were oval; growth and development process were basically the same;the fruits number of the fourth,fifth and sixth inflorescence were more than other inflorescences, and the same as fruits weight, which is the main factors of yield component. The research shows that this period is important for forming production of processing tomato and strengthening the management of water and fertilizer during this period could get high production.
