361: 104: 534:, which releases neutrally buoyant seeds into the water column. If an event occurs producing significant water turbulence, an immature fruit may break off from the peduncle. This buoyant fruit acts as a transportation vessel as it continues to develop. The fruit will be moved around by wind, currents, and tides until it eventually splits open to release the negatively buoyant seedlings into a new area. If the new location has favorable environmental conditions, the seedling will begin to grow. This is one way 158: 372: 399: 133: 388: 402: 401: 407: 405: 400: 406: 351:

and can put the meadow at severe risk if there is a disease outbreak. It has been found that where plants have been damaged mechanically, such as by the propellers of boats, the cut ends of rhizomes are unable to grow and holes may develop in the turtle grass meadow.
499:. Female plants typically grow one green flower, while males often produce three to five pink or white flowers. At night when male flowers are fully mature, they release mucilaginous pollen into the water column. The following morning, female flowers open. 529:
Seeds begin to develop in about 2–4 weeks if fertilization occurred. Female turtle grass fruits develop into green capsule about 20–25 mm in diameter and can include 1-6 small seeds. After about 8 weeks of growth, the fruit undergoes
