VARIABILITY OF PINUS-MUGO TURRA CLONES FROM OSTRY-WIERCH PEAT BOG

Present study aimed at determining genetic structure of the Pinus mugo Turra population, growing at a peat bog, on Ostry Wierch slopes in th e High Tatra mountains, in respect to the number of genotypes present in the population, and at defining variabilities of morphological and anatomical traits. In the examined plants, isoenzymatic analysis demon strated existence of only two genotypes (A and B), which formed relati vely vast clones. Mathematical-statistical analysis of 13 anatomical-m orphological traits of the needles proved that the examined clump cons isted of two clearly distinguishable groups, corresponding to the two earlier electrophoretically identified clones A and B. The obtained da ta allowed to conclude that the method based on anatomical-morphologic al measurements may, at least in some cases, permit identification of Pinus mugo clones.
