Plants secrete nectar to achieve two important mutual interactions with animals, namely pollination and indirect defence. Floral nectar is secreted inside flowers and attracts pollinators.

Extrafloral nectaries are morphologically diverse and include glandular structures that differ in location, size and shape. The purpose of this study was to determine the morphology and position of extrafloral nectarines on petiole and limb in several cherry tree varieties, namely: 'Giorgia’, 'Giant Red’, 'Ferrovia’, 'Kordia’, 'Regina’, 'Skeena’ and 'Lapins’.
