Studies and Utilization of Resources of Wild Fruit Trees in the West Part of Jilin Province

The west part of Jilin province is situated at the east border of Kerqin sandy land and in the middle and west of Songliao plain. It is in the crisscross zone of agriculture and husbandry in semi-humid and semi-arid area. The vast expanse of grassland in the west part is rich in resources of economic plants, among which there are 6 families, 11genera, 13 species and 2 varieties of wild fruit trees which are of great economic value and ecologic value. These wild resources are distributed over all the cities and counties, while apricot(Armeniaca sibirica(L) Lam.), white mulberry and Chinese dwarf cherry, etc. are most widely distributed and their amounts are the biggest. At present, apricot is the only fruit species in commercial use, while white mulberry and Chinese dwarf cherry are trial cultivated on small scale. Based on the situation of resources, suggestions on the utilization of wild fruit trees are put forward in the paper.
