Sperm competition does not occur in flowering plants as typically only a single pair of sperm cells is delivered for double fertilization. Two recent reports show that plants are capable of avoiding reproductive failure when defective sperm cells are released.
在有花植物中不会发生精子竞争，因为通常只有一对精子细胞被输送以进行双受精。最近的两项研究报告表明，当释放有缺陷的精子细胞时，植物有能力避免生殖失败。
