Three-way ANOVA for photosynthetic parameters, N allocation and acid phosphatase activity of endophyte-infected (EI) or uninfected (EF) ramets of Achnatherum sibiricum.

Note. N_A, total leaf nitrogen content; P_max, maximum net photosynthetic rate; PNUE, photosynthetic nitrogen use efficiency; P_T the fraction of leaf nitrogen allocated to all components of the photosynthetic machinery.
