1. 通过衰老叶片吸收过程进行的内部氮循环、全植物资源利用策略和性能之间的联系仍然难以捉摸。事实上，对这种潜在联系的测试受到基于成年叶和衰老叶的叶氮浓度“快照”的植物氮吸收效率（RE N）的经典评估的阻碍。 2. 我们通过非破坏性地跟踪 137 种天然拟南芥基因型叶子中氮浓度的时间过程，显着提高了测量叶子氮吸收的分辨率，这些基因型原产于欧洲各种气候，在温室中生长。除了经典的测量
1. The links between internal nitrogen recycling through the process of resorp tion from senescing leaves, whole- plant resource- use strategies and perfor mance remain elusive. Indeed, tests of such potential linkages are hampered by the classical evaluation of plant nitrogen resorption efficiency (RE N ) based on ‘snapshots’ of leaf nitrogen concentration from adult and senescent leaves. 2. We significantly increased the resolution for measuring leaf nitrogen resorption by non- destructively tracking time courses of nitrogen concentration in leaves of 137 natural Arabidopsis thaliana genotypes native to a wide range of climates across Europe, grown in a greenhouse. In addition to the classical measurement of
