英文摘要	The quantification of the allocation of nitrogen (N) and phosphorus (P) among plant organs is essential to improve our understanding of plant growth, life-history strategies and ecosystem nutrient and energy cycles. However, allocation strategies of N and P between terrestrial plant leaves and fine roots are unclear. Here, we compiled a global dataset comprising 807 terrestrial plant species to analyse the stoichiometric scaling of N and P between leaves and fine roots across species, families, plant groups, biomes and locations. We found that N and P, and N:P ratios manifest different scaling exponents (alpha-values) between leaves and fine roots. Specifically, overall alpha(N) and alpha(P) were >1 and <1, respectively, and alpha(N:P) = 1, indicating a higher proportional increase of N to fine roots and P to leaves. However, there were differences in alpha(N), alpha(P) and alpha(N:P) among major species, families, plant groups, biomes and locations. In addition, alpha(N) and alpha(N:P) increased with latitude; there was no clear trend for alpha(P). Mean annual temperature accounted for the greatest proportion of variation in alpha(N), whereas soil total P accounted for the greatest proportion of variation in alpha(P) and alpha(N:P). Synthesis. Our results demonstrate a divergent N and P allocation strategy between leaves and fine roots in terrestrial plants. This study improves our understanding of the effects of the environment (including changes in global climate and life-history strategies) on nutrient allocation patterns between these two important plant organs.
