NECTAR RESORPTION AND POLLINATION ECONOMY

The nectaries and nectar of three species (Helleborus bocconei, Cucurbita pepo and Linaria vulgaris) that differ in ecological, cytological and physiological characteristics are compared.
Nectar is resorbed in Cucurbita pepo and Linaria vulgaris, but in different ways and at different rates.
Nectar secretion and resorption, if any, are discussed in terms of the economics of the plant and environmental conditions.
