Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant’s stigma, hydrate, and germinate into pollen tubes. Thus, pollen tube germination and elongation are crucial for double fertilization, which, in turn, influences the grain yield of crop plants.
