Description In the present study, we analyzed the temporal trends of chlorophyll concentration or greenness measured using a SPAD meter (ChlSPAD), maximum net photosynthesis (Amax), stomatal conductance (gs), intrinsic water-use efficiency (Amax/E), nitrogen content per area (Narea), leaf length, plant cover and tuber and aboveground dry biomass in three potato varieties (Désirée, Unica and Sarnav). We compared plants grown at field capacity and under water restriction of 50% of field capacity. Our objectives were (i) to compare and relate the temporal pattern of chlorophyll concentration, maximum net photosynthesis, stomatal conductance, intrinsic water-use efficiency, leaf nitrogen content per unit of area, leaf length, plant cover and biomass accumulation across treatments and varieties and, (ii) to relate water restriction tolerance with temporal attributes of chlorophyll concentration in the assessed varieties.
