STUDY ON IDENTIFICATION OF TAXA OF RUBIACEAE FAMILY IN PHIA OAC – PHIA DEN NATIONAL PARK, CAO BANG PROVINCE

Abstract

Select and digitize 16 groups of characteristics to build a dichotomous type identification key and build a table of characteristics for 15 genera and 35 species of the Rubiaceae family in the Phia Oac – Phia Den National Park. Digitizing morphological characteristics is an important foundation for the application of informatics in identification of the genera and species.

Successful application of methods of identification for 15 genera and 35 species using dichotomous key, key using table of digitize characteristics, Microsoft Access software, combination of three softwares Paup, TreeView and Mega5.

The difference of the article is that it has applied Microsoft Access software to build a key and identify. Especially, the combination of 3 softwares Paup, TreeView and Mega5 allows to identify many species at the same time based on the tree of possible relationship of taxa.
