| This study characterised pollen grains morphologically and studied the genetic divergence between accessions based on morphopollinic characters. Seven accessions, including domesticated, semi-domesticated and wild species of Capsicum (C. annuum var. annuum, C. chinense, C. baccatum var. pendulum, C. frutescens, Capsicum annuum var. glabriusculum, C. baccatum var. baccatum and C. parvifolium), were cultivated in a greenhouse and their pollen grains collected and fixed during flowering. The pollen grains were acetolysed and described based on 13 pollinic characteristics (polar and equatorial axes, in an equatorial front view; ratio between polar axis and equatorial axis; equatorial axis in a polar view; thicknesses of the exine, sexine and nexine; apocolpus... |
