Influence of aluminium on growth and water relations of cowpea.
The effect of aluminium on shoot-root fresh weight and water relations [water potential (psiw), osmotic potential (psis), turgor potential (psip), and relative water content (RWC)] was studied in cowpea. The 3 microg g(-1) Al showed slight enhancement in psiw and psip in test plants. Concentrations beyond 3 microg g(-1) Al significantly decreased psiw (less negative) and psip. Relative water content (RWC) vis a vis the fresh weight was also affected adversely at higher Al concentrations.
