National Botanical Research Institute, Rana Pratap Marg, 226001, Lucknow, U.P., India aut Genome size and polyploidy variation in the tropical hardwood genus Terminalia ( Combretaceae ) [Elektronische Daten] [D. Ohri] Chromosome complements and 2C DNA amounts of six species ofTerminalia have been studied.Terminalia oliveri, T. myriocarpa andT. arjuna are diploid (2n = 24),T. chebula andT. bellirica are tetraploid (2n = 48),T. muelleri shows a triploid number (2n = 36). Two well demarcated groups of species are recognizable on the basis of chromosome length and 2C DNA values which range from 3.60 pg (T. oliveri) to 12.80 pg (T. bellirica) showing a 3.5-fold difference. Differences of DNA per basic genome or per chromosome are greatest (1.97-fold) betweenT. oliveri andT. arjuna. Two species groups (1)T. oliveri andT. chebula, and (2)T. myriocarpa, T. arjuna, T. muelleri, T. bellirica, therefore are well differentiated by DNA per basic genome, irrespective of polyploidy. The mean values of the two groups are 1.81 pg and 3.34 pg, respectively, showing a 1.84-fold difference. Within diploids and tetraploids there is 1.97-fold and 1.76-fold variation, respectively.
