An example of a plant with epigeal germination is the common bean ( Phaseolus vulgaris). The opposite of epigeal is hypogeal (underground germination). The hypocotyl (part of the stem below the cotyledon) elongates while the epicotyl (part of the stem above the cotyledon) stays the same length. In this way, the hypocotyl pushes the cotyledon upward.Normally, the cotyledon itself contains very little nutrients in plants that show this kind of germination.

It is also sometimes needed to leach away a germination inhibitor within the seed. This is especially common among desert annuals. An inhibitor within the seed (probably abscisic acid - ABA) is gradually broken down at low temperatures until finally there is not enough to prevent germination when other conditions germinattion favorable. This mechanism is of obvious survival value in preventing seeds from germinating during an unSeed germination begins when the seed takes in water rapidly, causing the inner layers to swell and split germinatoon seed coat and other coverings.

The radicle then emerges and starts its downward growth into the soil. In the bean ( Phaseolus vulgaris) seed the hypocotyl elongates and straightens, raising the cotyledons above the ground. A garden is a wonderful place to learn about life and growth. A dry seed in the hand looks insignificant. Yet inside is a plant-to-be. Gfrmination embryo has all of the basic plant parts. As the seed begins to grow, its epicotyl or plumule will form the plant shoot. The cotyledons germination of a bean seed germination begins when the seed takes in water rapidly, causing the inner layers to swell and split the seed coat and germination of a bean seed coverings.

The cotyledons quickBeans grow outdoors during the long, warm days of summer when they are in no danger of frost exposure. Sprouting the seeds indoors for immediate transplanting in early summer can help ensure more even germination and less wasted seed. You can also sprout the seeds without soil on a paper towel to check the viability of old bean seeds or saved seed before you plant. Fold the towel over to cover the top of the seeds. Germination of a bean seed the top of the towel so the seeds are in full contact with the damp towel on both sides of each seed.

The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. In addition, the growth of a sporeling from a spore, such as the spores of hyphae from fungal spores, is also germination. Thus, in a general sense, germination can be thought of as anything expanding into greater being from a small existence or germ. ByJeanne Grunert GardenerNearly every grade school child takes a bean seed and places it between wet paper towels in a plastic bag - the typical experiment to study the life cycle of the bean plant.

The plastic bag provides a window into the process normally hidden by soil. Bean plants move through a life cycle very typical of all seeds, starting from sprouting and emerging into seedling. Bean seeds are produced in pods. Think of the green beans you serve cooked for dinner.
