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

Note. NA, total leaf nitrogen content; Pmax, maximum net photosynthetic rate; PNUE, photosynthetic nitrogen use efficiency; PT the fraction of leaf nitrogen allocated to all components of the photosynthetic machinery.

备注：NA，总叶片氮含量；Pmax，最大净光合速率；PNUE，光合氮利用效率；PT，叶片氮分配给光合机构所有组成部分的分数。
