Results of three-way repeated-measures analysis of variance, with ‘integration’, ‘nitrogen form’ and ‘water status’ as between-subject effects, for differences in chlorophyll fluorescence parameters [maximum (F_v/F_m) and effective (ΦPSII) quantum yield of photosystem II] and spectral reflectance [photochemical reflectance index (PRI) and chlorophyll content index(CHL)] between offspring ramets
