In Berberis lycium anthers on alternate stamens dehisce, thus prolonging the male function so that pollination is affected and reproduction is ensured. The large pollen sac of each bithecous anther after the appearance of longitudinal dehiscence slit moves away from the filament while remaining attached at the tip of the connective and then orients in such a way that pollen-laden surface faces the stigma. No pollen is available to receptive stigma as pollen grains remain stuck to the anther sac. They do not get dispersed even by wind. Pollination and consequently reproduction is ensured through the intervention of insect, which does not affect pollen transfer to the stigma directly but by touching the base of the staminal filament while foraging nectar secreted by nectaries at the base of corolla, thus leading to staminal movement. This makes the dehisced anthers stick to the stigma and deposit pollen there.
在枸杞小檗中，相间的雄蕊的花药开裂，从而延长雄性功能，使得授粉受到影响并确保繁殖。每个具双药室花药的大花粉囊在出现纵向开裂缝后，从花丝移开，同时仍附着在药隔顶端，然后以这样一种方式定向，即载有花粉的表面朝向柱头。由于花粉粒仍粘在花药囊上，没有花粉可供有接受能力的柱头利用。即使借助风，它们也不会散开。通过昆虫的介入确保授粉并进而确保繁殖，昆虫不会直接影响花粉转移到柱头，而是在采集花冠基部蜜腺分泌的花蜜时触碰雄蕊花丝基部，从而导致雄蕊移动。这使得开裂的花药粘在柱头上并在那里沉积花粉。
