E. Gurgul et B. Herman, INFLUENCE OF NITROGEN, PHOSPHORUS AND POTASSIUM ON CHEMICAL-COMPOSITION AND ACTIVITY OF SOME ENZYMES IN CELERY DURING ITS GROWTH, Biologia plantarum, 36(2), 1994, pp. 261-265
The influence of N, P, K supply on the contents of dry mass, chlorophy
ll (a+b), vitamin C, saccharides and the activities of peroxidase (E.C
.1.11.1.7), catalase (E.C. 1.11.1.6), and acid phosphatase (E.C.3.1.3.
2) in leaves of celery plants during their growth stages was investiga
ted. A correlation between the amount of N, P, K and the chemical comp
osition and catalytic activities of enzymes was found.
