Seven different developmental stages of soybean seedling development. Seven different stages during the development of soybean seedlings are defined based on time, size of radicles, hypocotyls, roots and appearance of germinating cotyledons. Stage 1: Imbibed seed for 24 hours; pre-emerging hypocotyls. Stage 2: Yellow cotyledons; emerging radicle 8–10 mm long. Stage 3: Yellow cotyledons with slightly green edges; 15–20 mm long hypocotyls. Stage 4: Yellow-green cotyledons; hypocotyls 30–35 mm long. Stage 5: Yellow-green cotyledons above the ground; primary roots starting to develop. Stage 6: Mostly green cotyledons above the ground; growing straight from the hypocotyl. Stage 7: Fully green cotyledons; plants 6–7 cm long above the ground; the root system fully developed; cotyledons upright; unifoliolate exposed.
