Abstract excerpt
Ploidy level and geographical distribution were investigated in Japanese Lonicera caerulea L. Flow cytometric analysis revealed the presence of DNA diploid and DNA tetraploid plants in Japan. Chromosome observation confirmed that diploid and tetraploid plants showed 2n = 2x = 8 and 2n =4x = 36, respectively. The DNA diploid populations were found only in lowland mires, Betsukai, Bekanbeushi, Kushiro and Kiritappu...
