characteristics of seeds dispersed by wind

Many wetland plant seeds can be dispersed both by surface water and by wind (Bouman and others 2000; Middleton and others 2006; Soons 2006). 2. Seeds that are dispersed by the wind have several characteristic adaptations that allow them to be successful with that strategy. Seeds such as Foxglove are minute and are easily blown about by the wind. 460) are carried by wind like pollens. How can wind help disperse seeds? Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Poppy seeds, for example, can hardly be called aerodynamic, but these plants still depend on the wind. Larger wind-dispersed seeds are generally heavier and therefore require features such as parachutes or wings to help keep them aloft. – sycamore, ash, maple, lime, dandelion and thistle When pods dry, they split open suddenly and shooting the seeds away from the parent plant and this is easy when the wind is there. Two examples are the fluffy seeds of the dandelion and the rose-bay willow herb blowing far and wide on the wind. Orchid seeds and poppy seeds are like that. Seeds of Cinchona are … Modifications in seed structure, composition, and size help in dispersal. These structures are adaptations in the seeds for dispersal to the remote places. Some seeds are very small and light, almost like dust. Therefore, the seeds are dispersed by the wind. Majority of the plants belong to the Asteraceae disperse their seeds by the help of wind. Seeds specially adapted for wind dispersal are characterised by the following: ADVERTISEMENTS: 1. all over the landscape. 1. Examples of different seeds that are dispersed by the wind (Depending on where you live, you may be able to find some of these seeds outside. There are "parachutes" on top of some seeds, like milkweed and dandelion seeds. “Salt-and-pepper-shaker” style pods keep the seeds from falling directly below the parent plant. This makes it easy for the wind to carry them. An important detail for a wind-dispersed seed is that it is very light.It must be able to float easily on wind or else it will drop straight to the ground. Hairy structures, light weight, small size etc. They are usually lighter and smaller than other seeds. 1) Seeds dispersed by wind- Many seeds get dispersed by wind and therefore they may develop hair like structures that offer air resistance so that they are carried over long distances before falling on the ground. Very small, dry and dusty seeds as those of orchids (weighing as little as 0.004 mg in some cases—Fig. For example, Dandelion seeds have developed very light and fluffy parachute-like structures. Other plants depend on the wind in different ways. This is why plants that use wind dispersal produce so many seeds. E.g. They have special structures that catch the air, such as wings or fluff. Some fruit have built-in mechanisms so they can disperse by themselves, whereas others require the help of agents like wind, water, and animals (Figure 1). Seeds which have wings and hairy parachutes on them are carried by the wind. example- cotton seeds, drumstick etc. help the seeds to disperse by the help of wind.
