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.
