Abstract:

The surface phosphatase activity of different wheat cultivar roots was determined using two substrates, p-nitrophenyl phosphate (pNPP) and methylunbelliferyl phosphate (4-MUP). Comparison of root phosphatase between PMEase activity was noted with pNPP substrate. The P-limited plants also recorded higher activity over the P-sufficient plants. The maximum phosphatase activity was at 10 days seedlings as compared to the 5 and 15 days seedlings. The cultivar Indus-66 showed highest PMEase activity as compared to Jauhar-78 and Pavon.
