Study of relationship between Prunus arborea(Blume) Kalkman with other species in natural forest in some Northern provinces

Abstract

Research on relationship between Prunus arborea (Blume) Kalkman and
other tree species was conducted in four natural forest status IIA, IIB, IIIA2
and IIIA3 in four provinces: Bac Giang, Tuyen Quang, Hoa Binh and Son
La. The results indicated that P. arborea are related with timber species in
all three forms including independent relations, positive relationships and
negative interactions, of which only 8 species have independent
relationships with P. arborea, 34 - 86 species have positive interaction with
P. arboreaat 2 levels (weak and moderate) and 94 - 238 species have
negative interaction with P. arborea (at three levels degrees are weak,
moderate and relatively tight). Species that have a positive interaction with
P. arboreathat have been used in reforestation including Canarium album,
Canarium tramdenum, Castanopsis ducampii, Castanopsis indica,
Castanopsis cerebrina, Choerospondias axillaris, Schima walichi,
Endospermum chinense, Machilus thunbergii, Dipterocapus retusus,
Cinnamomum cassia, Styrax tonkinensis,Madhuca pasquieri, Cinadenia
paniculata, Cinnamomun obtusifolium, Mangglietia conifera, Ailanthus
triphysa and Walsura elata. These are species of high economic value,
promising species for selecting to mixed plantaions with P. arborea for
timber supply in Vietnam.
