widgeon grass reproduction

Females are brushed in warm browns with a gray-brown head and a smudge around the eye.

Leaves are alternate, simple, and thread-like (less than 1/32 of an inch wide) up to 4 inches long with sheaths. Younger Niles are unable to provide the required reproduction rates needed to provide vegetation control or to be a good forage source. Quiet lakes and wetlands come alive with the breezy whistle of the American Wigeon, a dabbling duck with pizzazz. flowering widgeon grass in Tampa Bay. Plant foods such as smartweeds, pondweeds, and widgeon grass often occur naturally in wetlands, while agricultural foods like corn, soybeans, and rice must be cultivated. Breeding: Widgeon Grasses use both an asexual and sexual reproduction. They grow flowers which are fertilized by an adjacent plant. Water depth and turbidity are the major factors influencing the vegetative growth of widgeon grass. (1985) collected flowering manatee grass in the bay and found reproductive specimens of shoal grass in nearby waters. Hence, it is … Also like most grasses, it can produce new shoots from broken stems and roots but relies more on massive numbers of seeds. Lewis et al. Fruits are small (< 1/32 inches), dark-green and pear-shaped. Breeding males have a green eye patch and a conspicuous white crown, earning them the nickname "baldpate." Widgeon grass is a completely submerged perennial plant with single or multi-branched stems up to 3 feet long. With certain exceptions (see apomixis), to produce seed a grass plant must produce flowers with male and female parts. Flowers and fruits in clusters at the end of individual stalks.

Widgeon grass can be removed by raking or seining it from the pond but will reestablish from any remaining roots and seeds. Grasses may reproduce sexually by seed (sexual reproduction), or asexually via vegetative propogation (tillers which arise from adventitious buds on culm nodes, rhizomes, and stolons). When the temperature falls outside this range, vegetative growth ceases. This section deals only with sexual reproduction involving flowers, pollination, and seeds. Widgeon grass appears to have two growing seasons (spring and fall) that are controlled by water temperature ranging from 18.5°C to 30°C. Widgeon grass can be found from intermediate to brackish zones with 10 to 20 ppt of salinity, and even in some saline zone areas where salinity is greater than 20 ppt. Fertilization to produce a phytoplankton or algal “bloom” prevents the establishment of most bottom rooted aquatic weeds and produces a strong food chain to the pond fish.
