Seasonal activity of non-specific acid and alkaline phosphatases in beech (Fagus sylvatica) leaves

Abstract: The activities of acid and alkaline phosphatases along with phosphorus content in leaves of European beech (Fagus sylvatica L.) were studied for a period from April to October. The phosphorus content of beech leaves was highest in April, at the beginning of the vegetation period; from May to October it was twofold lower than in April. Acid phosphatase activity (per unit fresh weight) in leaves collected from the middle part of the crown decreased significantly in May and July compared to the enzyme activity in April. In both the low and middle parts of the crown, the acid phosphatase activity had a peak in August, and thereafter decreased in September and October. No correlations between acid phosphatase activity and phosphorus concentrations were found. Alkaline phosphatase activity was very low and in some cases near the detection limit during the whole observation period.
