Fig. 2From: Acclimation with humic acids enhances maize and tomato tolerance to salinityIon content (Na+, K+, Ca2+) and ion ratio (Na+/K+, Na+/Ca2+ + Mg2+) of maize seedlings root tissues in the first phase of experiment acclimation period (control × humic acids, HA) and under moderate salt exposition (control × primed state, PS). The means (n = 4) was followed by the standard deviation in mg g−1 of root fresh weightBack to article page
