2023-02-13 Are aluminum and iron resorbed from old leaves? doi:10.57760/sciencedb.j00001.00463 en Leaf resorption is an important mechanism for plant nutrient conservation, but not all elements are resorbed by plants. It is generally believed that aluminum (Al) and iron (Fe) are not resorbed from old leaves due to their toxic effects. However, the fact is that positive Al and Fe resorptions have been found in some specific cases. To date, no one has addressed these specific cases and the mechanisms underlying.Here, a data synthesis was conducted to explore the patterns and controls on leaf resorption efficiency of Al and Fe, based on 34 published studies with 274 data points. We aimed to answer whether and why Al and Fe can be resorbed from old leaves. nutrient resorption; trace elements; aluminum; iron; global analysis Nan Hu Qinggong Mao Xibin Sun Qianhao Xu Meimei Li Hao Chen PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
