The methods of sunflower seed propagation include wind propagation, animal propagation, river propagation, terrain propagation and man-made propagation. Wind propagation refers to that after the sunflower is mature, its seeds fall off and are blown away by the wind. Animal propagation refers to that some animals leave some sunflower seeds in other places when they carry them. There are many ways for sunflowers to spread seeds, such as wind propagation, animal propagation, river propagation, terrain propagation and man-made propagation. Among them, the more common modes of propagation are wind propagation and animal propagation.
Wind propagation is a way for many plants in nature to spread seeds. After sunflower is fully mature, its seeds will slowly fall off from the flower plate, and some of them will be blown away by the wind, so as to take root and sprout in other places.
Animals can spread sunflower seeds because many squirrels, birds and other animals will pick sunflower seeds for consumption. They will leave some seeds in the process of transporting seeds, and these seeds will grow into sunflowers where they are left.
