The corolla remains after anthesis and is often reflexed. The species is protandrous, the anthers spilling pollen within six or seven days of anthesis. Proximal cauline leaves are withered at anthesis. Female catkins are erect during anthesis, but otherwise pendant. After anthesis, the pistil is long. This outcrossing occurs when the species florets are open during anthesis. The style continues to grow until anthesis, when the nectaries begin to produce nectar. "F. culmorum" conidia during anthesis and FHB can last from anthesis to grain harvest. Pedicels are 10-12 mm in anthesis, 12-17 mm in fruiting, erect-patents. The petals when present are equal or unequal, often caducous during anthesis. This tree produces thousand of fruits, ripening three months after anthesis. After anthesis, if the flower was successfully pollinated, a single fruit develops. "F. graminearum" infects wheat spikes from anthesis through the soft dough stage of kernel development. This process, female anthesis, is followed by male anthesis, in which the pollen is produced. Frequent rains between anthesis and kernel filling stages facilitates the occurrence of FHB.
