摘要
甘蓝型油菜初花期后，叶片仍是主要光合器官，但各类叶对产量的作用不同，无柄叶＞短柄叶＞分枝叶＞长柄叶，对产量的影响分别为７．４％－１５．５％、５．１％－１４．６％、３．３％－１４．６％和０．３％──－５．０％．各类叶对结角数和角粒数的影响与对产量的影响一致，但对千粒重的影响相反．
Leaves were the main photosynthesis organ of rape after flowering, but every kind of leaves had different function in the yield. The contribution to yield was stem -less leaves 7. 4 %-15. 5%>short stem leaves (5. 1%-14.6% )>branch leaves (3. 3% - 14. 6% ) >longstem leaves (0. 3%-5. 0% ). The effects of these types of leaves on the number of siliquae and seeds per pod were almost the same as that on the yield,while there was an opposite effect on 1000-seed weight.
