项目摘要
Decreasing the high nitrogen (N) balance surpluses in winter oilseed-rape production requires the breeding and cultivation of N-efficient cultivars. The overall objective of the project is the clarification of the role of leaf senescence and N mobilization from leaves in grain yield formation of rapeseed genotypes at limited N supply (N efficiency). The project thus represents the bridge between the projects within the research groups dealing with molecular aspects of N dynamics during leaf senescence and the oilseed-rape breeders aiming at improving the N efficiency of the crop. We hypothesize that (i) genotypic differences in delayed leaf senescence are governed by root growth and activity and/or leaf-inherent factors which can be characterized already at early vegetative stages and (ii) the main effects of delayed leaf senescence on reproductive yield are higher photosynthetic productivity of the leaves and longer duration of N translocation to the reproductive organs. To test these hypotheses we will conduct experiments with genotypes differing in N efficiency and leaf senescence at yield/growth-limiting and unlimiting N supply in the field in cooperation with a rapeseed breeder, under controlled conditions until maturity, and at the seedling stage in cooperation with the molecular working groups.
为了减少冬油菜生产中的高氮平衡盈余,需要选育和培育氮高效品种。该项目的总体目标是阐明叶片衰老和叶片氮动员在有限氮供应条件下油菜基因型籽粒产量形成中的作用(氮效率)。因此,该项目代表了叶片衰老期间N动态分子方面的研究小组内的项目与旨在提高作物N效率的油菜育种者之间的桥梁。我们假设:(i)延迟叶片衰老的基因型差异是由根的生长和活动和/或叶片固有的因素,可以在营养生长早期已经表征和(ii)延迟叶片衰老对生殖产量的主要影响是较高的光合生产力的叶片和较长的持续时间的N转运到生殖器官。为了验证这些假设,我们将进行实验,不同的基因型在产量/生长限制和不限制氮供应在该领域与油菜育种家合作,在受控条件下,直到成熟,并在苗期与分子工作组合作的氮效率和叶片衰老。
