Cytogenetic research regarding species with ornamental value identified in the North-east area of Romania
In the paper are presented data regarding the number of somatic chromosome determine at three species of plants with ornamental value from spontaneous flora of Romania (Allium ursinum L., Centaurea phrygia L., Dianthus armeria L.) and cultivated in the experimental field to evaluate the adapt capaci...
