What are the methods of seed dispersal?
This article brings you the methods of seed dispersal and related content about green plant propagation techniques, including the methods of seed dispersal and the propagation skills of seeds, which will be introduced by the site editor for netizens.
Every form of life reproduces in its own way. Cows and horses have legs, birds have wings, and as plants that cannot move, nature has endowed them with special ways to disperse seeds. So, what are the methods for plants to disperse seeds? Let's take a look at these seed dispersal methods of plants!
Animal Dispersal
Plants that rely on animals to disperse seeds include Xanthium, Tribulus, Bidens, Vitis thunbergii, Pinus, Cherry, Pine nuts, and Chestnuts. For example, seeds of Bidens and Xanthium have spines and barbs on the outside, which will stick to the fur of animals upon slight contact. Fruits of plants like cherry and wild grapes are mostly fleshy, and after being eaten by birds, the seeds are randomly excreted everywhere through the digestive tract. Chestnuts and pine nuts are taken home by squirrels to store, some of which are eaten, and the rest will germinate the following year.
Wind Dispersal
Plants that rely on wind to disperse seeds include Dandelion, Willow, Poplar, and Maple. These seeds are usually light and can float in the air, and a gentle breeze can carry them to remote places. Some plants have special structures suitable for wind-assisted flight, such as the fine hairs on cotton and willow seeds, the umbrella-like pappus on dandelion fruits, and the winged structures on seeds of pine, maple, and elm.
Water Dispersal
Plants growing in or near water usually disperse seeds with the help of water, such as Coconut trees and Water lilies. When the fruit of a coconut tree matures, its hard shell acts like a small boat floating away with the sea current. After being washed ashore by the waves, it grows into a new coconut tree. The fruit of a water lily matures and falls into the water, where it decays slowly, and the seeds with spongy outer coats float on the surface, drifting with the waves, and finally sink to the bottom to germinate.
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. When these seeds mature, the dry and hard fruit skin often bursts with a "pop" under the scorching sun, and the seeds are shot out like bullets to a distance. The most interesting is a plant called "爆炸草" (Exploding cucumber), which, upon slight contact, will drop and instantly shoot out the seeds from the top.
The above is a complete introduction to the methods of seed dispersal and seed propagation techniques, hoping to be of help to you. Don't forget to check out more experience and common sense!
