The paper presents a study results on N, P and K content in annual bark and tree of the seedlings during dormancy (2002-2003). The studies involved the seedlings of nine autochthonous pears cultivars and one wild pear tree (Pyrus cummunis L.). The investigation proved NPK content to be a genetical property of the seedlings. The average content of nitrogen (N) of one year old seedlings was from 0.54% (cv. Buzdovanka) to 0.78% (cv. Kacmorka). The average content of phosphorus (P) of one year old seedlings was from 0.0475% (cv. Jarac) to 0.0615% (cv. Kalicanka). The average content of potassium (K) of one year old seedlings was from 0.258% (cv. Kalicanka) to 0.475% (cv. Kacmorka). Owing to a favourable ratio of P and K:N, seedlings Sijerak and Kacmorka are to be singled out for generative rootstock production. The stated issue is of a general, biological significance, upon which cultural practices are based. The aim of the paper was to clarify NPK content in annual pear seedlings during dormancy, and thus, to contribute to a more rational fertilization usage in the production of pear seedlings.
