Abstract

Diospyros munA.Chev. ex Lecomte a large timber species, which has high economic and biological value. In Vietnam's Red Book, it is endangered at upcoming and in the World Red Book, it is placed on the critically endangered, should be preserved. Research results silvicutural characteristics
of Diospyros munat Cuc Phuong National Park showed that, this species is distributed on Renzin yellow, brown yellow or yellow feralitic soils, with soil depth from 1.0 to 1.6 meters, relatively high humus content, soil pH = 5 - 6.5, It grows scattered or form clumps in high scrub jungle or on
the limestone mountains with elevations below 700 meters. In the natural forest, Diospyros munusually grows with other tree species such as Nephelium chryseum, Dimocarpus fumatus, Callophyllum ceriferum, Sinosideroxylon racemosum and random relationship with these species. Diospyros munis the dominant species in which values can be IV = 11.02%
to be greater than 4 other dominant species and less than Nephelium chryseumspecies (IV% is 12.96%). Mun has the ability to regenerate whole seeds (86%) and shoots (14%) relatively good.
