Distribution and morphology of extrafloral nectaries in some Cucurbitaceae

Distribution and morphology of extrafloral nectaries in some Cucurbitaceae Abstract A study of extrafloral nectaries has been made in the Cucurbitaceae to ascertain their structure and assess their taxonomic potential. Nineteen species representing nine Old World genera and one New World genus were examined. These included Telfairia occidentalis, Telfairia pedata, Momordica charantia, Lagenaria siceraria, Citrullus lanatus, Luffa aegyptiaca, Cucurbita moschata and Trichosanthes cucumerina, which are of economic importance and cultivated in Nigeria for their leaves and/or fruits. Observation of the regularity of ant and insect-visitors, along with tests for glucose and β-glucosidase enzymes, revealed the presence of extrafloral nectaries in nine species. Considerable variation exists in the distribution and morphology of nectaries between genera, especially in the tribe Benincaseae. The nutritional and ecological significance of the occurrence of extrafloral nectaries in Telfairia occidentalis is discussed.
