Karyomorphological Studies in Wrightia tomentosa and W. tinctoria; Multipurpose Tree Species of Aravallis in South-East Rajasthan

Abstract

Karyomorphological studies have been carried out in 2 species of the genus Wrightia. The somatic chromosome numbers 2n=22 and 2n=20 were recorded for W. tomentosa and W. tinctoria, respectively. The karyotypes of the species were more or less symmetrical. The significance of karyotypic variation in speciation of the genus Wrightia has been discussed.
