With 2 Figures and 2 TablesS u m m a r y Z u s a m m e n f a s s u n gThe study was conducted to confirm the traditional separation of varieties of Hibiscus rosa-sinensis L. according to corolla colour. Measurements were made on live plants of three varieties: red, orange and white, for plant height, number of branches, angles of branches, leaf size and floral whorl dimensions. Leaf shape, apex, base and floral behaviours at anthesis were also assessed. Micromorphological features like stomata1 indices, complex types, their distribution on adaxial and abaxial surfaces, presence of foliar trichomes as well as pollen grain features were assessed. Results revealed enough evidence to confirm the traditional separation of these varieties despite the affinity of macromorphometric features. Suggestions were made to attempt explaining the paradox of high pollen grain fertility as against no fruit set and vegetative reproduction in the species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
