Collecting, evaluation and utilization of walnut (JugSans regia L.) in Yugoslavia

摘要

Walnut growing in Yugoslavia has a long tradition. Because of favourable soil and climate conditions, this species is grown in all fruit-growing regions. There are 1 735 000 fruit-bearing trees in Yugoslavia. The major fruit-growing regions are: Timok, Podrinje,'Metohija, Zapadna Morava, Juzna Morava, Fruska Gora, etc. The walnut trees are mostly concentrated in the altitudes from 100 to 400 m. In the central part of the country, individual walnut trees occur at 1000 m asl, while in the south the trees can be found even at 1200 m asl. Owing to a continuous generative propagation, the walnut structure is rather heterogeneous.
