    INVESTIGATION OF EFFECTS OF SEED MATURATION CHARACTERISTICS ON NATURAL AND ARTIFICIAL REGENERATION WORKS IN THE SCOTCH PINE (Pinus sylvestris L.) AND BLACK PINE (Pinus nigra Arn. Ssp. Pallasiana Lamb. Holmboe) STANDS OF THE WEST BLACKSEA REGION

    Suat Tosun1 and Metin KaradaZ1

    Black pine (Pinus nigra Arn. Ssp. Pallasiana Lamb. Holmboe) and Scotch pine (Pinus sylvestris L.) are main tree species. Black pine forests cover 2283175 ha totally of which 1474098 haare of good quality, and 809077 ha degraded high forest. Scotch pine forests cover 717468 ha totally of which 454612 ha are of good quality, and 262856 hadegraded high forest (O.A.E. 1980).

    When we looked at regeneration studies between the years 1964 and 1992 (age classes forest management was applied in these years), it seems that the natural regeneration success of species according to plans is only about 5-10%, excepting removals in natural storied Black pine stands.
