Abstract

The nectary of Asclepias syriaca is in the stigmatic chamber. Nectar flows from there by a capillary system to the nectar reservoirs (cuculli). The fluid connection from the stigmatic chamber to the cuculli allows quick mixing of liquids in the system. Nectar in the stigmatic chamber is the germination medium for the pollen. Pollinia do not germinate in dry stigmatic chambers. The nectar must contain 5%-30% sugars for pollen germination. The nectar in the cuculli is the reward taken by insect pollinators and may become altered by physical (e.g., evaporation or dilution) or biotic (e.g., microbes, enzymes) factors.
