Nitrate reductase activity in the different phenophases of ‘palmer’ mango cultivated in the semiarid

Nitrate reductase is the enzyme that catalyzes the first reduction reaction in the nitrate assimilation process, an important nitrogen (N) source. This element is one of the macronutrients required in greater amounts by mango (Mangifera indica L.), exerting a great influence on the growth and devel...
