“…Higher phosphatase activity has been recorded in mycorrhizal plants by Kumar et al (2008) and Wu et al (2011) under water stressed conditions. Role of potassium in improving phosphatase activity has been investigated by Ali and Meihy (2015). Increased phosphatase activity in mycorrhizal plants under drought stress helps in increasing tolerance of plants to water stress by increasing the availability of phosphorus (Stancheva et al 2008).…”

A pot culture experiment was carried out under greenhouse conditions to study the effect of potassium fertilizer (70 mg kg -1 , K1, and 100 mg kg -1 , K2) and arbuscular mycorrhizal fungi (Glomus mosseae and Acaulospora laevis) alone and in different combinations on water stress amelioration of Vigna mungo during three growth stages. Treatment of the plants with mycorrhizal fungi and potassium improved physiological parameters including chlorophyll concentration, membrane stability, phosphatase activity, leaf protein concentration and mycorrhization over the untreated control regardless of water stress treatments. Imposition of water stress at reproductive stage caused maximum reduction in membrane stability, leaf protein concentration, phosphatase activity and mycorrhization as compared to stress during other stages. Treatment combinations of G. mosseae + A. laevis + K2 and G. mosseae + A. laevis + K1 proved to be the best for promoting physiological and morphological parameters studied both in stressed and unstressed plants. A combination of G. mosseae and K2 was the best among double inoculation treatments while G. mosseae was the best among single treatments of either dose of potassium and A. laevis for stress alleviation and growth amelioration. Imposition of water stress during vegetative stage had the least effect on the physiological parameters studied, except for leaf area, which was adversely affected. Chlorophyll concentration was the most affected parameter by water stress at the pod formation stage.
