Abstract
The purpose. To determine stimulating effect of combined fertilizers and biostimulants of propagation upon morphometric indexes of annual seedlings of pine, grown in film glasshouse. Methods. Field — for determination of quantity indicators of edaphic germinating ability, preservation of plants of pine; laboratory — for study of morphometric indexes of seedlings, length and mass of above-ground and rooted parts; mathematical — for calculation of ratio between mass of above-ground part to mass of rootage; statistical - for analysis of reliability of the gained results of probes. Results. Changes in morphometric indexes of annual seedlings of pine under impact of combined fertilizers and biostimulants of propagation are shown. Conclusions. Multicomponent fertilizers in combination with biostimulants of propagation manifest stimulating effect on germinating ability, preservation and formation of seedlings of pine in hothouse conditions.

Key words: pine, seedlings, combined fertilizers, biostimulants of propagation, germinating ability, preservation.
