Any dormancy requirements that prevent germination must be overcome. Soaking the seeds for 8 hours before sowing enhances germination. Environmental stimuli regulate AtGA3ox1 and AtGA3ox2 activity during seed germination. Gibberellins are involved in the natural process of breaking dormancy and other aspects of germination. Various plants require different variables for successful seed germination. Host root exudate contain strigolactones, signaling molecules that promote striga seed germination. The soybeans have to cool down to allow spore germination and abundant growth of mycelium. Burned areas are favorable to the successful germination of redwood seeds. The nutritional changes upon germination and sprouting are summarized below. After lotus seed germination, crude protein and fat levels in the endosperm significantly increase. This favors the germination and growth of those seeds. This rodent buries seeds whole in locations favorable for seed germination, unlike other animals. These mutants reflect the importance of ABA in seed germination and early embryo development. Seeds are lipid-rich, to provide energy for germination and early growth. Red imported fire ants have negative impacts on seed germination.
