Grass Seed Germination

A grass plant starts as a seedling that enters the germination process when it is able to absorb water; which is known as imbibition. Hormones within the plant react to the presence of water by producing hydrolytic enzymes, which will in turn dissolve the endosperm into amino acids and carbohydrates that are used as nourishment in early development.

Eventually, the primary root (called the radicle) will emerge from the embryo and so will a protective tissue known as the coleoptile. Over time, the coleoptile will develop into the grass plant’s initial leaf and additional primary roots will form from the radicle.
