Abstract

Some observations were conducted on «Nuggett» apricot variety in arder to evaluate annual changes of N, P, K in various tree organs (flowerbuds, flowers and fruits; leaves and shoots) in relation to shoot and fruit growth. Total amount of N, P, K in flower-buds, flowers and fruits increased progressively during growth season. As percent of dry rnatter, on the contrary, mineral content of these organs in the same period decreascd. N, P and K leaf content (as percent of dry matter) decreased from spring-flush to leaf-fall; while percent mineral content of shoots increased from late summer to autumn and decreased from late autumn, to following spring-flush, flowering and fruit growth.
