| 摘 要： | 以具有单性结实基因型的Ｓｅｖｅｒｉａｎｉｎ（ｐａｔ－２／ｐａｔ－２）和Ｍｏｎａｌｂｏ（ｐａｔ－２／ｐａｔ－２）及其非单性结实的姊妹系Ｍｏｎａｌｂｏ（＋／＋）为试验材料，研究了在４种不同授粉处理下的坐果率、单果重、产籽量及单株产量等方面的差异。结果表明：具有ｐａｔ－２／ｐａｔ－２基因型的番茄材料在不授粉条件下仍能坐果且果实正常膨大，而普通基因型番茄材料则不能坐果；但在正常授粉条件下，ｐａｔ－２／ｐａｔ－２型番茄产籽量低于其普通型姊妹系；就同一ｐａｔ－２／ｐａｔ－２型番茄而言，未经授粉的坐果率、单果重、单株产量等方面的一项或两项仍在不同程度上低于其正常授粉处理，其差异幅度及表现形式因材料不同而异；蕾期授粉可对ｐａｔ－２／ｐａｔ－２型番茄材料的坐果和产量产生较明显的促进作用

| Abstract: | In two parthenocarpic lines Severianin (pat-2/pat-2), Monalbo (pat-2/ pat-2) and one isogenic line of Monalbo (+/+) without pat-2 gene fruit set percent (FSP), fruit weight (FW), seed productivity (SP) and single plant yield(SPY) were investigated after 4 different pollination treatments. The two parthenocarpic lines could set fruit and the fruits normally developed even without pollination but non-pathenocarpic line could not if no pollination performed. SP of parthenocarpic line was much lower than that o... |
