Data from: Why are flowers sweeter than fruits or buds? Variation in extrafloral nectar secretion throughout the floral ontogeny of a myrmecophile

Extrafloral nectar provision during floral ontogeny in ant-plants has not been widely studied. Extrafloral nectar secretion differed between leaves associated with buds, flowers, and fruits, and peaked during anthesis when pollinators were present. This ontogenetic variation may result from mixed selective pressures involving strategies for defense and mutualist management.

蚁植(ant-plant)的花发育进程(floral ontogeny)中花外蜜(Extrafloral nectar)的供给，尚未得到广泛研究。与芽、花及果实相关联的叶片间，花外蜜的分泌量存在差异，并在传粉者活跃的开花期(Anthesis)达到峰值。该发育进程中的变异，可能源于涵盖防御策略与共生伙伴管理策略的复合选择压力。
