assortment structure - Opis:
- Poland has rather rigorous regulations concerning forest tree seed zones. The high commercial quality of the coastal (northern) and upland (southern) beech provenances has stipulated the need to verify their performance also in the central Poland as possible quality seed source. A trail consisting of three open pollinated half−sib provenances has been established in Forest Experimental Station in Rogów in the year 1963. After the stand had reached the age of 44 years, a prognosis has been made focused on assessing the final age assortment structure of particular trees. The results show that the local population is at present the poorest and it is expected to produce the lowest wood quality in the mature stand. It is concluded that, following the results of 44 years, both the upland beech and – first of all – the coastal beech are due to their excellent performance potentially valuable seed source for the central Poland.
