There are several ways for seeds to spread. There are many ways of seed spreading, and the speed of seed spreading is very fast. Seeds are important organs for plant reproduction, and all kinds of plants in nature have their own ways to spread seeds. Let's look at the way seeds spread.
What are the ways of seed transmission? 1 1. Wind transmission means that seeds are spread by wind. For example; Dandelion seeds have fluffy balls composed of white fluff, which can be dispersed in the wind and take root and sprout elsewhere. Willow seeds have white fluff, like catkins fluttering in the wind, so it is called catkins, and it is also one of the plants that spread seeds by the wind.
2. Hydraulic transmission, plants that spread seeds by water flow: coconuts, lotus seeds, gorgon nuts, etc. These plants generally grow near the water, and their seeds have hard shells. When it matures, it falls into the water, floats with the waves, and takes root after being washed to the shore.
3. The representative plants of animal transmission are Xanthium sibiricum, wild grapes and pine nuts. Among them, the seeds of Xanthium sibiricum have barbs outside. Animals will stick to their skin when they pass by and follow them far away. The bright colors of wild grapes will attract birds to eat, thus spreading seeds.
The seeds spread by birds are mostly fleshy fruits, such as berries, drupes, hidden flowers and hidden fruits. Birds peck at the seeds of Lauraceae and spit them out. After the fruit is eaten, the seeds pass through the digestive tract and are excreted at will. Plants that spread seeds by birds are a relatively advanced group, because birds spread seeds farthest in all ways.
5. Sticky spread, some plants have sticky seeds and will spread by themselves. Animal transmission: it is to spread seeds by animals. For example, the fruit of Vitis amurensis is the favorite food of birds. Birds eat the fruit of Vitis amurensis and excrete undigested seeds after digestion. The environment is suitable, and the seeds of Vitis amurensis began to take root and sprout. Then there is ejection propagation, that is, the seeds are spread by plants themselves.
Expansion;
Seeds can be spread by wind, animals, spraying, rolling and water flow. The surface of the seeds spread by the wind will be covered with a layer of white fluff, which will be scattered with the wind. The seeds spread by animals are brightly colored or have barbs on their surfaces. The rolling seeds are round, which is convenient for them to spread to further places.
What are the ways of seed transmission? 2 1, spread by the wind.
The way of seed transmission is wind transmission, because some plants have light seeds with fluffy fibers or thin wings. When they are blown by the breeze, they will float in the air, and then they will float with the wind. When the wind stops, they will fall into the soil and take root. Plants spread by the wind include dandelion, Emilia sonchifolia and reed.
2. Animal transmission
The way of seed transmission is animal transmission, and the plants spread by animals are Xanthium sibiricum, Bidens bipinnata, Cynanchum multiflorum, peach blossom, etc. Because their seeds are covered with barbs, they can stick to the fur of animals. When animals change their hair or accidentally fall into the soil, seed transmission is completed.
3. Jet propagation
The method of seed propagation is ejection propagation, because when some plants grow to a certain extent, the epidermis around the seeds will explode, and the seeds will be scattered all over the ground after the explosion. Generally, beans, such as sesame, red beans and mung beans, are used to spread seeds with slingshots.
4. Water transmission
Seeds are spread by water, with the help of water. Plants include coconut, lotus seeds, gordon euryales and so on. They usually grow near the water. When the seeds mature, they will fall into the water and be washed away by the water, and then they will take root and sprout here after being slapped on the shore by the water.
What are the modes of seed transmission? 3 1, spread by the wind.
Wind transmission is the most common plant seed transmission. Most seeds spread by wind have fluffy fibers and thin wings, which can be blown anywhere by the wind. Let the seeds fall to the ground to take root and sprout, but the unstable wind will also bring the seeds into the river and prevent the seeds from sprouting.
2. Animal transmission
Seeds can spread to far places through animal transmission. Generally, plants that rely on animals to spread their seeds will have barbs and stick to animal fur or human clothes. The most common plant that spreads seeds by animals is Xanthium sibiricum, which has many barbs on its surface.
3. Jet propagation
The seeds of some plants, such as Impatiens balsamina, Sesame and Fried Sauce Grass, will be ejected by the explosive force of the seed shell. But in this way, the transmission distance is very limited, but it can effectively ensure that every seed can spread out.
4. Hydraulic transmission
Some plants growing near the water rely on this mode of transmission. The seeds of these plants have hard shells, which can resist the influence of the external environment. When the seeds of these plants mature, they will fall into the water, drift with the tide and be washed to the shore to take root and sprout.
5. Bird transmission
Birds are the least efficient at spreading, although they can spread far away. When birds eat plant seeds, some seeds are excreted as feces before being digested by birds' intestines and stomach, and fall to the ground to take root and sprout.
What are the ways of plant seed transmission? 10 introduction of plant transmission modes!
There are many ways to spread plant seeds, such as wind transmission, water transmission, elastic transmission, animal transmission and catapult transmission. Ten specific ways of plant transmission are as follows:
1. Plant seed transmission mode 1: water transmission.
Water transmission refers to the transmission of seeds through water. For example, when the coconut fruit matures and falls, it will be washed ashore by the tide with the current, and then take root and sprout to grow new coconut trees.
2. Plant seed transmission mode 2: Wind transmission.
Wind is spread by wind, the most common is dandelion seed, which is very light in weight. When the wind blows, they will float far away, and once the environment is suitable, they will take root and sprout.
3. Plant seed transmission mode 3: elastic transmission.
Elastic propagation means that when the seeds of plants are ripe and touch the fruit, the peel will roll back, pop out the seeds, and then bounce around like shells to grow. Common ones are rape, mustard, peas, soybeans, mung beans, sorrel, impatiens and so on.
4. Plant seed transmission mode 4: Animal transmission
Animal transmission means that some seeds or fruits grow hairs and stick to animals, such as Xanthium sibiricum. In addition, some animals eat fruits, and the finished fruit seeds remain in the animals. Because it can't be digested, it spreads in all directions with feces.
5. Mode of plant seed transmission 5: Self-transmission.
Self-propagation means that when the seeds are mature, they will directly fall to the ground or bounce to other places under the action of gravity, and then take root and sprout, such as persimmons and large-leaf eggplant.
6. Mode of transmission of plant seeds 6: Adhesion transmission
Common adhesion and transmission is Xanthium sibiricum seeds. Because the fruit of Xanthium sibiricum has barbs, it is easy to attach to people or animals, and then it falls to other places to take root and sprout with the help of people and animals.
7. Plant seed transmission mode 7: rolling transmission.
Rolling propagation means that the seeds fall on the hillside after maturity, and then roll for a certain distance by their own gravity to take root and sprout. Such as chestnut and hairy chestnut.
8. Mode of transmission of plant seeds: mechanical transmission
Mechanical transmission means that when seeds are harvested mechanically, bullets are planted in all directions and then grow. Impatiens, for example, spread like this.
9. Mode of plant seed transmission 9: Artificial transmission
Artificial transmission means that people keep seeds until the next year after harvesting them.
10, plant seed transmission mode x: falling transmission.
Falling-flower propagation refers to the fruit falling to the ground naturally after it matures, the fruit decays and deteriorates, and the internal germ gradually matures in the process of decay.
