“…In blueberry, NO 3 reductase activity (NRA) has been detected in the leaves and roots (Dirr et al, 1972(Dirr et al, , 1973Townsend, 1970). In citrus trees, which have NRA in leaf tissue (Bar-Akiva and Sternbaum, 1965), a greater portion of NO 3 --derived N vs. NH 4 + -derived N had been translocated from the roots to the shoots 48 h after 15 N labeling (Serna et al, 1992). This result suggests that root-to-shoot NO 3 transfer may have preceded much of the NO 3 reduction.…”

“…In previous reports evidence has been presented aboul Ihe exislence of nitrate reductase enzyme activity in citrus leaf fragments (1,2). It has also been established that in regard to its dependence on nitrate (2) and molybdenum supply (9), the system is identical to the nitrate reductase enzyme described for several annual plants (5).…”

“…[8][9][10] However, rapid diagnoses of macronutrient imbalances using enzyme techniques have so far only been explored with nitrogen, but might be possible with the aid of appropriate enzymes for other macronutrients such as potassium and magnesium.…”

“…In cases of zinc deficiency in plants the activity of aldolase, a zinc-requiring enzyme, has been shown to be reduced in the 1eaves.l Similarly the activity of ascorbic acid oxidase is reduced by copper deficiency,2 peroxidase and catalase by iron and manganese d e f i~i e n c y ,~-~ and nitrate reductase by molybdenum and nitrogen deficiency. [8][9][10] However, rapid diagnoses of macronutrient imbalances using enzyme techniques have so far only been explored with nitrogen, but might be possible with the aid of appropriate enzymes for other macronutrients such as potassium and magnesium.…”
