Which methods to spread pollen make plants bear more fruit

Pollen can be divided into wind-borne pollen and insect-borne pollen according to the mode of transmission

Wind pollen refers to pollinated pollen with the help of wind, generally pollen grains are small, light in weight, large in quantity, not easy to contain animal hormones, generally not easy to cause allergies, pine pollen is the pollen of pine trees, is a typical wind pollen.

Pine pollen, also known as pine yellow, pine has a very strong ability to resist pests and diseases, so it is not easy to produce pests and diseases, so there is no need to use pesticides, no pesticide residues; Pine trees also do not need to be fertilized, and the leaves are its best fertilizer, so there is no need to worry about pollen pollution from chemical fertilizers.

Insect pollen refers to the pollen with insects as the medium of propagation, generally pollen grains are large, heavy, insect pollen because the insect itself contains animal hormones, insects will bring their own animal hormones to the pollen when collecting honey, people are easy to cause allergies after eating, bee pollen is a typical insect pollen.

In addition, insect pollen has a characteristic, there are many types of pollen, because insects will collect honey from various flowers, so the pollen is not pure, not single, and when bees collect nectar everywhere, the pollen will be stained with various impurities, and the impurities are difficult to remove by honey, in addition, it is necessary to pay attention to prevent bees from collecting pollen with pesticide residues, because some plants can not avoid spraying pesticides.

In 1860, the Swedish botanist Linnaeus named pollen after the Latin pollen (which originally means "powerful, energetic"), which reflected the essence of pollen.

Ancient applications

China is an ancient civilization with edible pollen earlier, more than 2,200 years ago, the great poet Qu Yuan of the Warring States period in "Lisao" has "the fall of the morning drink magnolia, the fall of the autumn chrysanthemum at the end of the meal", the falling flowers referred to here are falling flowers, and the withered falling flowers naturally have pollen; The Song Dynasty's "Tujing Materia Medica" recorded: "Puhuang is the stamens powder in the flower, as thin as gold thread, when it wants to open, it will be taken, and the fruit is very good to eat with honey."

Pollen honey syrup "is the ancient traditional food of our country, in 1502 Suzhou published the farmer's daily manual "convenient for the people" in the "dry honey method" is a good way to make pollen honey syrup: add kilograms of pollen per 5 kilograms of honey, first boil the honey in the casserole, and add the pollen when the drip does not disperse.

"Convenient Picture Compilation" is the Ming Dynasty Hongzhi period of Wu County Zhixian according to the predecessor unsigned work "Convenience Compilation" adaptation, it can be seen that China's food pollen nectar preparation earlier than the Song Dynasty, to the Ming Dynasty has become a folk food.

Wang Shixiong of the Qing Dynasty wrote "Suixingju Diet Recipe" described the production method of pine pollen pastry: white sugar was boiled with water and pine pollen was added; In the Qing Dynasty, it was recorded in the "Records of the Year of the City of Beijing" and the "Records of the Years of Yanjing" that the pine pollen made cakes were: elm money cake, rose cake, vine flower powder cake, nine-flower cake, and there were also those who did not mention the name of the flower species, collectively referred to as "flower cake" and "spring cake".

These explanations have occupied an important position in China's recipes since the Ming and Qing dynasties.

1.Self-pollination: The process by which the mature pollen grains of a plant are transferred to the stigma of the same flower and can be fertilized and set fruit normally is called self-pollination. In production, pollination between the same plant and different flowers and the same variety is often regarded as self-pollination.

Such as rice, wheat, cotton and peaches.

2.Cross-pollination: Even if it is a hermaphroditic flower, under normal circumstances, the stamens of the same flower will not mature together, therefore, the pistil of the general flower receives the pollen of the other flower, which is cross-pollination.

In dioecious plants, the only way to produce unisexual flowers in monoecious plants is to carry out cross-pollination.

Such as rape, sunflower, apple tree, etc. are cross-pollinated plants.

Plants need to rely on the help of various external forces to spread pollen to the stigma of other flowers. Under natural conditions, cross-pollination relies mainly on insects or wind. Flowers that rely on insect pollination are called insect-borne flowers, such as apple blossoms.

Flowers that rely on wind pollination are called wind flowers, such as corn flower beds, where many kinds of flowers are grown. ）

Methods of pollen dispersal include: wind vector (dandelion); insect vector (pollen) ; water-borne (goldfish algae); There is also its own ** pop-up (beans); Human-transmitted, animal-carried (Xanthus).

1. Spread by water.

Coconut: Spread by water, when the coconut is ripe, the coconut fruit falls into the sea and drifts away with the sea.

Water lilies: The fruits of water lilies sink to the bottom of the water when they are ripe. When the pericarp decays, the seeds covered with a spongy outer seed coat float up and float elsewhere.

2. It is spread by small birds or other animals.

Cherries, wild grapes, wild ginseng: The seeds are eaten by small birds or other animals, and because they cannot be digested, they are excreted with feces and spread in all directions.

Pine nuts: They are taken away by squirrels when they store their winter food.

3. Rely on the wind to spread.

Red-skinned willow: It is the catkins that fly to spread the seeds far away.

4. There are also methods for mechanically disseminating seeds.

Impatiens: The fruit of impatiens will bounce and shoot the seeds in all directions, which is a method of mechanical dispersal of seeds.

There are also many legumes that use mechanical seed dispersal.

1. What do plants use to spread pollen?

2. What are the other ways for plants to disperse pollen?

3. What are the ways of transmission of pollen from plants?

4. What can plants use to spread pollen?

1.Plants use wind and insect vectors to spread pollen.

2.Wind refers to the power of the wind, such as corn, and poplars are used to disperse pollen when they bloom.

3.They have a large pollen count, are dry and light, and are easily blown away by the wind.

4.Insect vector transmission is conducive to the transmission of insects, including bees, flies, moths, butterflies, etc.

5.This plant has large flowers, bright colors, aromas or nectar glands, sticky, and easy to stick to insects.

This is a very interesting question! Some plants can spread pollen on their own, a phenomenon known as self-pollination or self-pollination. Self-pollination refers to the transfer of pollen from the stamens to the stigma of the same flower, thus achieving self-fertilization.

Some plants employ a self-pollination strategy, mainly because they live in places with relatively harsh environmental conditions, in the absence of cross-pollinators. The flowers of certain plants have structural adaptations, such as the position of petals and stamens relative to the stigma to promote self-pollination. In addition, these plants may also have a heteroploidy reproductive style, which increases genetic diversity even when self-fertilizing.

Some common self-pollinating plants include Solanaceae (such as tomatoes and eggplants), legumes (such as peas and soybeans), lilies (such as tulips and lilies), and daffodils (such as daffodils and hyacinths). These plants tend to have both male and female stamens maturing at the same time, thus promoting the occurrence of self-pollination.

Hope this satisfies your queries! If you have any questions about plant pollination or other biological topics, I'd love to do so.
