Other claims from this paper (18)
- Intervention effect Municipal effluent (T2) increased foliar mineral accumulation in tree seedlings relative to canal water control.
- Intervention effect Effluents T4, T6, T7 and T8 gave the highest foliar accumulation of Mn, Fe, Cu and Zn in tree seedlings.
- Intervention effect Effluents T4, T6, T7 and T8 affected foliar N, P, K, Ca, Mg and Na concentrations in tree seedlings.
- Intervention effect Seedlings under T3 had less foliar Mg, Mn, Fe, Cu and Zn than under other effluents.
- Association Eucalyptus camaldulensis foliage had high P, Mn, Fe, Cu and Zn concentrations compared with Acacia nilotica.
- Intervention effect Metal stress in T6, T7 and T8 seedlings reduced net photosynthesis (Pn) by 87%.
- Intervention effect Metal stress in T6, T7 and T8 seedlings reduced transpiration (T) by 81%.
- Intervention effect Metal stress in T6, T7 and T8 seedlings reduced stomatal conductance (g) by 67%.
- Intervention effect Metal stress in T6, T7 and T8 seedlings reduced leaf water potential (LWP) in the early two months.
- Association Eucalyptus camaldulensis maintained high leaf water potential and Pn compared with Acacia nilotica.
- Association Eucalyptus camaldulensis had low transpiration and stomatal conductance compared with Acacia nilotica.
- Association High leaf water potential in T2 seedlings was associated with high Pn, transpiration and stomatal conductance.
- Intervention effect Physiological parameters lowered in T3 and T5 seedlings.
- Intervention effect T1, T2 and T5 seedlings maintained high LWP, Pn, transpiration and stomatal conductance throughout the experiment.
- Mechanism Physiological parameters decreased in T3 seedlings through Na-induced deficiency of Mg, Ca, Mn, Fe, Cu and Zn.
- Mechanism The enhanced physiological functions in T5 were probably due to an ameliorative effect of municipal effluent through increased mineral status.
- Mechanism Excess accumulation of Na, Mn, Fe, Cu and Zn leads to metal toxicity that adversely affects physiology of tree seedlings.
- Recommendation Mixing effluents and/or removing excess would ameliorate the toxic effects and is a better management practice for tree irrigation.
