Palynomorphology of the subfamily Juanulloideae Hunz. (fam. Solanaceae Juss.)
Keywords:
Pollen morphology, Solanaceae, JuanulloideaeAbstract
The study of the pollen morphology of 8 species from 5 genera (Juanulloa Ruiz et Pav., Hawkesiophyton Hunz., Markea Rich, Schultesianthus Hunz., Trianaea Planch. et Linden) of the subfamily Juanulloideae Hunz. (fam. Solanaceae Juss.) and species Solandra viridiflora Miers of the subfamily Solanoideae has been carried out with the help of light (LM) and scanning electron (SEM) microscopes. Pollen grains meridonal 3(4)-colp-orate(oroidate) or 3 (4)-colp-porate(poroidate)-orate(oroidate) with long, intermediate or short colpi. The exine ornamentation are psilate, scabrate, plicate (very often covered in Ubish body), sometimes reticulate, the muri do not join usually. The presence of the infrageneric pollen polymorphism on both the type of aperture and exine sculpture is mentioned for the majority representatives of the investigated genera.
