Damage to petals may have varying effects on the reproductive success of the plant. The variation may depend on the kind of damage to the corolla. Whether the damage is limited to the corolla, as is usually the case with nectar-robbing perforations, or extending to the reproductive parts of the flower, as in the case of florivory holes, might determine the extent of the effect on the plant’s reproduction. We examined the various perforations in the flowers of Arctostaphylos pungens and correlated their presence with fruiting success. We found that though florivory holes were highly associated with damage to reproductive parts, fruiting success did not differ significantly between flowers with the two kinds of damage. Although nectar-robbing perforations were not associated with reduced number of fruit produced, they were significantly correlated with reduced number of fruit that contained seemingly viable seeds. The implications of our findings are discussed in the context of pollination and antagonism.

尖叶曼萨尼塔角Arctostaphylos pungens（Ericaceae）的花中的植物和花蜜穿孔及其对植物繁殖成功的影响。

花瓣受损可能会对植物的繁殖成功产生不同的影响。变化可能取决于对花冠的损害类型。是将损害限制在花冠上（通常是抢花蜜的情况），还是将花扩展到花的生殖部分（如在花孔中），可能会决定对植物繁殖的影响程度。我们检查了Arctostaphylos pungens花中的各种穿孔并将他们的存在与取得成功联系起来。我们发现，尽管花孔与生殖器官的损害高度相关，但两种损害的花朵之间的结实成功率没有显着差异。尽管抢花蜜的穿孔与减少的产果量无关，但它们与减少的包含看似可行种子的果实的数量有显着相关。我们的发现的意义在授粉和拮抗的背景下进行了讨论。
