A comparative study of karyomorphology among three populations of Garcinia indica (Clusiaceae) (Thomas-Dupetite) Choisy.
Garcinia indica is a tree species of the family Clusiaceae. This species is endemically distributed only in Ratnagiri and Sindhudurga district of Maharashtra. Plants collected in particularly Dive Agar and Sawantwadi show morphological variations. Mitotic chromosomes from three different population from the Konkan region were studied using propionic orcein stain. Chromosome numbers 2n = 54 is reported for all the populations. Three populations differed from each other in some aspects. Karyotype analysis showed that Deorukh population from Ratnagiri region showed one pair of satellite and one pair of secondary constrictions while Otawane population from Sawantwadi showed one satellite chromosome but differ in pattern of secondary constriction. Third, Diveagar population from Raigad district showed three pairs of satellite chromosomes and one pair of secondary constriction. So, it can be concluded that, plants from Bapat Garden of Dive Agar and Otawane region can be considered as cytotypes.
