Soil phosphorus mediates trade-offs between constitutive and induced defences in young pine trees.

ABSTRACT:

Main conclusion

Nutrient availability, namely soil phosphorus, modulates trade-offs between constitutive and induced defences in maritime pine, with high phosphorus weakening these trade-offs and shaping plant allocation to different defensive strategies. Abiotic factors modulate trade-offs between plant functions, but their influence on trade-offs between constitutive and induced defences remains poorly understood. We tested for such trade-offs in maritime pine (Pinus pinaster) and examined whether soil phosphorus availability affected these defensive correlations. We conducted a greenhouse experiment with six-month-old pine seedlings from 33 half-sib families, exposing half of the plants from each family to either low or high soil phosphorus availability, one of the main limiting
