Fig. 2From: Effects of different water management options and fertilizer supply on photosynthesis, fluorescence parameters and water use efficiency of Prunella vulgaris seedlingsDiurnal variations in leaf transpiration (Tr) (a), stomatal conductance (Gs) (b), intercellular CO2 concentration (Ci) (c) of P. vulgaris exposed to two soil water (W) conditions and three levels of fertilizer (F), n = 6–8. F0: no fertilization, F1: 0.12 g N + 0.2 g P2O5 + 0.1 g K2O kg−1 soil, F2: 0.24 g N + 0.4 g P2O5 + 0.2 g K2O kg−1 soilBack to article page
