From: Assemblage of indigenous arbuscular mycorrhizal fungi and green waste compost enhance drought stress tolerance in carob (Ceratonia siliqua L.) trees

Figure 4

Effects of water regimes (WW: well-watered; open bars and DS: drought stress; filled bars) on (a) chlorophyll-a; chl ‘a’, (b) chlorophyll-b; chl ‘b’, (c) total chlorophyll; chl ‘T’, and (d) carotenoid in control carob plants and plants amended with compost (C) and/or assemblage of indigenous arbuscular mycorrhizal fungi (AMF). Data are mean ± SE (n = 5). Means followed by the same letters within the same time point are not significantly different at P < 0.05 (Tukey’s HSD). The upper case represents the differences within WW or DS water regime, and the lower case represents the differences within a one-time point.
