What are the methods of seed dispersal in plants
Do you know about these? What are the methods of seed dispersal in plants and the small experiences of plant cultivation with seed dispersal techniques, the following editor will introduce to you.
Every life will reproduce in its own way. Cows and horses have legs, birds have wings, and as immobile plants, nature has endowed them with special methods of seed dispersal. So, what are the methods of seed dispersal in plants? Let's take a look at these seed dispersal methods of plants!
Animal Dispersal
Plants that rely on animals for seed dispersal include Xanthium, Tribulus, Bidens, Vitis, Pine, Cherry, Pine nuts, and Chestnuts. For example, the seeds of Bidens and Xanthium have刺毛 and barbs on the outside, which will stick to the animal's fur when lightly touched. Cherries, wild grapes, and other plants mostly have fleshy fruits, whose seeds are ingested by birds and then randomly excreted everywhere after passing through the digestive tract. Chestnuts and pine nuts are taken home and stored by squirrels, some of which are eaten, and the rest will take root and sprout the following year.
Wind Dispersal
Plants that rely on wind for seed dispersal include Dandelion, Willow, Poplar, and Maple, etc. These plant seeds are usually light and can float in the air, and a gentle breeze can carry them to the ends of the earth. Some plants have special structures suitable for wind-assisted flight, such as the fine villi on cotton and willow seeds, the umbrella-like pappus on dandelion fruits, and the winged structures on pine, maple, and elm seeds.
Water Dispersal
Plants growing in or near water usually disperse their seeds with the help of water, such as Coconut trees and Water lilies. After the fruit of the coconut tree matures, the hard shell acts like a small boat floating with the sea current to distant places, and it will grow into a new coconut tree after being washed ashore by the waves. The mature fruit of the water lily falls into the water and decays slowly, and the seeds with spongy outer coats float on the water surface, drifting with the waves before finally sinking to the bottom to take root and sprout.
Explosive Dispersal
Explosive dispersal means that seeds are shot out like bullets. Common plants include Oilseed rape, Mustard, Peas, Soybeans, Mung beans, Oxalis, and Impatiens, etc. After these plants' seeds mature, the dry and hard fruit skin often bursts with a "pop" sound under the scorching sun, and the seeds are shot out like bullets fired from a gun. Among the most interesting is a plant called "shooting cucumber," which, when mature, will脱落 and instantly shoot the seeds inside out upon slight touch.
The above sharing of the methods of seed dispersal in plants and detailed explanation of seed dispersal techniques, hoping this article can bring you help in green plant management!
