Abstract

In this study, the pollen morphology of 18 wild taxa of Lathyrus L. grown in Turkey: L. pallescens (Bieb.) Koch, L. brachypterus Cel., L. haussknechtii Sirj., L. karsianus P. H. Davis, L. satdaghensis P. H. Davis, L. nivalis Hand.-Mazz, L. atropatanus (Grossh.) Sir., L. armenus (Boiss. and Huet) Sirj., L. cyaneus (Stev.) Koch var. cyaneus, L. cyaneus var. pinnatus Davis, L. digitatus (Bieb.) Fiori, L. tukhtensis Czecz., L. variabilis (Boiss. and Ky.) Maly, L. spathulatus Cel. L. elongatus (Bornm.) Sirj., L. cilicicus Hayek and Siehe, L. boissieri Sirj., and L. bitlisicus Peşmen was examined by light microscopy and scanning electron microscopy. The pollen grains were 3-zonocolporate, of spheroidal-subprolate-prolate (P/E = 0.957-1.252) types, and medium in size. Equatorial view: rectangular or elliptical-obtuse-convex, polar view: circular, triangular or quinquangular-obtuse-convex. The smallest pollen grains belonged to L. elongatus (P = 36.972/E = 38.636) and the largest to L. cyaneus var. cyaneus (P = 46.332/E = 32.864). The ornamentation was perforate-foveolate or slightly reticulate. Some photographs included in this work were taken using both light microscopy and scanning electron microscopy. © 2011 Springer-Verlag.
