Abstrakt

The experiment was conducted under conditions of foil tent in the Forest Experimental Station in Rogów. During the study, the one-year old, not subjected to controlled mycorrhization Scots pine seedlings with containerized root system were used. The seedlings were produced in container nursery from the Jabłonna Forest District and grew by 5 months in loose sand and silt with humidity of 40, 55 and 70% of full ground water capacity.
The studies have shown that significantly greater increase of, both overground parts and root systems, had seedlings growing on the coherent ground than on the non-coherent one. Higher humidity on the non-coherent ground has slowed the growth of overground part and accelerated the development of a root system, while on the coherent ground the reverse correlation was noticed. Research showed that the pine seedlings produced in a container nursery tolerate well tested moisture levels of sandy soil, while the coherent soils moisture at 70% proved to be too high for the proper development, particularly the root systems.
