Chromosome numbers and meiotic behavior are presented for the first time for Hypericum caprifoliatum (2n=48), H. cf carinatum (2n=48) and H. polyanthemum (2n= 32) and confirmed the H. perforatum (2n=32) number. Chromosomes are very small (ca. 1 to 2 mm). Meiotic irregularities, such as uni and multivalents, un-oriented chromosomes, bridges and laggards were very frequent in H. caprifoliatum and H. cf carinatum. Meiotic indexes ranged from 44.0 to 73.0% in H. caprifoliatum, 66.0 to 77.0% in H… CONTINUE READING
