Opis:
The research was carried out in 2006 within the area of forest nursery in Okalewo, the Forest Inspectorate Skrwilno (Central Poland, at 53º02´N, 19º23´E). The aim of the study was to determine the effects of root pruning in one-year Scots pine seedlings (Pinus sylvestris L.) on their growth after transplanting. The vertical roots of one-year Scots pine seedlings were pruned to the length of 5, 10, 15 i 20 cm and measured. The scope of measurements included: stem length and thickness, total root length, root length within thickness classes, surface root area, root volume as well as the number of root tips and ramifications. The measurements of root systems were performed with the use of a scanner and WinRhizo software. The seedlings were transplanted and were growing in the nursery all through the vegetation season 2006. In October of this year the seedlings were lifted from the ground and measured again at the same scope. Reiterated measurements allowed evaluation of increment characteristics after transplanting. The results indicated negative impacts of intensive root pruning before transplantation on seedling survival rates. Severe pruning of seedling vertical roots had negative effects on increment gained by both above- and underground seedling parts. Pruning roots to 5 cm of length significantly decreased pine seedling survival rate of. On the other hand, 20 cm long roots have no significant effects on seedling survival and increment but they can cause difficulties in seedling nursery cultivation.

Opis:
The paper presents research on influence of nursery soil compaction, composed of peat (90%) and perlite (10%), on the growth of seedlings of Pinus sylvestris grown in containers. Polyethylene nursery are containers used for the seedling production. These containers were filled with three different densities of the peat and perlite substrate (0.3, 0.5 and 0.7 g·cm-3). During the experiment, nursery containers were initially placed in a plastic tent for a period of two months, and then for three months further months in an open nursery field. Growth measurements for individual plants were the length of shoots and the root system, root collar diameter, root and shoot dry weight and photosynthetic rate. There was a relationship between the extent of compaction of the soil substrate and all analyzed growth parameters of seedlings. A more compact substrate adversely affected on the number of grown seedlings and their length but positively influenced the dry mass of pine seedlings.
