ABSTRACT

The research studied the influence of the volume and construction of “Hiko” and “Plantek” containers on acorn germination, resistance of root-closing substrate, height of aboveground plant parts and length of root systems of oak seedlings. The cell volume in “Hiko” containers varied from 25 cm3 to 530 cm3 while in “Plantek” containers – 115 cm3 – 275 cm3. The seedlings were grown in greenhouses of arch type with polycarbonate coating and automatic watering. Peat-moss was used as a substrate. Average ground germination was 70.3%. The dependence of acorn germination from the container volume was not established. The volume of root system depends on the volume of container cells. In “Hiko” and “Plantek” containers, the mass of small roots of oak seedlings decreases with a decrease of the cell volume. In “Hiko” containers the maximum output percentage of seedlings with the height of more than 12 cm root neck thickness of more than 3 mm is observed at a cell volume of 350 cm3. The worst cells for seedling growth were of the volume 25 cm3. Containers “Hiko V 90 AirBlock”, “Plantek 100 F”, “Hiko V 50 SS”, “Plantek 36 F”, “Plantek 49 F”, “Plantek 100 F” proved to be not suitable for the cultivation of oak seedlings because of the root system deformation.

Keywords: oak tree; seedlings with the root-balled tree system; standard seedlings; containers; cell volume
