Conditions required for seed germination are different among species. Some seed of tropical and subtropical plants may germinate before the maturation of their fleshy fruit, e.g. papaya species, while seed from most deciduous trees have a period of after-ripening before germination. The after-ripening period, also referred to as rest or dormancy has also been observed in some vegetable crops and ornamental flowers.
