STUDIES ON DETERMINATION OF COLD HARDINESS OF SOME IMPORTANT HAZELNUT CULTIVARS

The purpose of this experiment was to determine the cold resistance of Tombul, Sivri, Palaz, Çakildak and Kalinkara cvs. which were the most popular hazelnut cvs. in the region. The applications covered period of November to March of 1988–1989, 1989–1990, 1990–1991 years.

One- year-old shoots of the mentioned cvs. were exposed to artificial frost test by the fortnight intervals in the said period(November-March).

The end of this studying Kalinkara has been found as the most susceptible hazelnut cultivar.
