Seed Dispersal by Water Narrowleaf willow seeds are small, fragile, light, and sufficiently aerodynamic to be wind-dispersed . The small capsules (4-5 mm long) contain tiny seeds, each of which is topped with a tuft of silky hairs. produce many small seeds that are dispersed primarily through the air by winds (anemochory) and sometimes secondarily by flowing water (hydrochory). Seeds contained within fruits need to be dispersed far from the mother plant so that they may find favorable and less-competitive conditions in which to germinate and grow. The first step when planting desert willow seeds is to acquire the seed. Willow seed-dispersal patterns key to control A CSIRO project looking at the reproductive ecology and dispersal ability of the most aggressive invasive willow species in Australia is providing critical information to help land managers more efficiently control this weed. Many plants have seeds that use water as a means of dispersal. It is possible that long-distance wind dispersal of Cushion willow seeds and pollen is aided by the monsoon system in the HDM and the eastern Himalaya. Seed dispersal: In general, willow seeds are dispersed primarily via wind and water [49,135,144,162]. In this paper I identify another way willow seeds are dispersed – being blown by winds while sailing or floating on the surface of standing water, here termed pleustochory. The natural regeneration of Salix caprea L. in disturbed forest areas is an important ecological phenomenon occurring during succession in temperate and boreal forests. The seeds float away from the parent plant. Seed banking: Narrowleaf willow seeds are nondormant and quickly become desiccated if not on a moist substrate [44,139]. You will want to harvest the seeds in late summer or early fall when the pods turn dry and brown, but prior to the pods splitting open. In addition to protecting the embryo, the fruit plays an important role in seed dispersal. The reason for this is because the main method of seed dispersion for willow trees is water. Knowledge of the timing and extent of seed dispersal in goat willow is still rudimentary. Some plants make use of water to disperse their seeds. Willows (Salix spp.) If the seeds fall in the water, they are carried away by the tide to grow somewhere else. Mangrove trees live in estuaries. Dispersal of Seeds by Water. The seeds of the orchid plant, dandelions, swan plants, cottonwood tree, hornbeam, ash, cattail, puya, willow herb, are all examples of plants whose seed are dispersed by the wind. Water dispersal. If a mangrove seed falls during low tide, it can begin to root in the soil. The light and fluffy seeds are easily dispersed by wind and water. CSIRO researchers have found that an average willow tree can produce as many narrow seed pods. ... Willow and Silver Birch, are often found in the middle of moorland, far from any other trees, but along the course of a stream. This species reproduces by seed and vegetatively via the rooting of detached twigs or branches. Parachutes include seeds or achenes (one-seeded fruits) with an elevated, umbrella-like crown of intricately-branched hairs at the top, often produced in globose heads or puff-like clusters.The slightest gust of wind catches the elaborate crown of plumose hairs, raising and propelling the seed into the air like a parachute. Patterns of willow seed dispersal, seed entrapment, and seedling establishment in a heavily browsed montane riparian ecosystem June 2005 Canadian Journal of Botany 83(6):678-687 In experiments, seeds of Salix gooddingii C.R. Reproduction and Dispersal. We studied seed dispersal and genetic offspring relationships on five storm-disturbed forest sites (4–13 ha) at 715–900 m a.s.l. After the desert willow’s showy flowers bloom, the tree will produce long, 4 to 12 inch (10-31 cm.)
