Why is it difficult for Venus flytrap to self pollinate?

Venus flytraps reproduce through seeds and belong to seed plants. Venus flytraps can be self-pollinating, but they usually have to be hand-pollinated to actually bear fruit. However, artificial pollination of Venus flytraps is not always successful because the timing of pollination is not right.

When the flowers of the Venus flytrap bloom, not both the female and the stamens mature at the same time. When the flower first blooms, its stamens are ripe, but the pistils are not ripe, and it is useless to pollinate it. Venus flytrap pistils usually ripen one day slower than stamens, so the correct thing to do is to wait the day after the flowers bloom.

Then the pollination work is carried out. We can also look at the shape of the pistil to determine whether it is ripe. The stigma at the end of the immature pistil is rounded, and the stigma at the end of the mature pistil will be split open like a cotton flocculent; Only mature pistils can be successfully pollinated [2].

If pollination is successful, the flowers will wither within 1 2 days, and the ovary (the base of the pistil) will swell, and the fruit will ripen in a few weeks. The seeds of the flytrap are black and teardrop-shaped; A fruit usually contains a dozen seeds. The number of seeds depends on the health and size of the plant, and a strong plant usually bears a little more seeds.

Sometimes the pollination method is correct, but the seeds still do not bear fruit, and the biggest problem is that the Venus flytrap is not strong enough, or it is not continuously given enough light during flowering, and even if it is successfully pollinated, it will be difficult to produce seeds.

Venus flytrap seeds are not shelf-tolerant, so try to sow them as early as possible after harvesting. Sometimes, if you want to do cross-pollination, but the plants to be used for crossbreeding do not bloom at the same time, you can collect the pollen first and store it in the refrigerator to prolong the life of the pollen.

Since flowering is a nutrient-intensive activity for plants, do not allow the Venus to bloom unless necessary, especially if you want to grow a large plant, cut off the stems as soon as possible to prevent the Venus from depleting nutrients on flowering. Since the flytrap blooms when the season comes, some weakened plants will barely bloom, but the stems are cut off to protect the plants.

It has a typical phenomenon of overripening of the stamens of each flower, and the stigma of the pistils does not open until the pollen has dispersed to receive pollen, which makes the self-pollination of the Venus flytrap difficult

This phenomenon is called the phenomenon of overripening of stamens, in which the stamens of the flower mature first, and the pistils are dispersed before they can mature and be pollinated.

Because they are male and female communities. And the time for the pollination of stamens and pistils is not the same.

Because the stigma of the pistil is only open after the pollen has dispersed, it is able to accept pollen.

Because his two long teeth can't touch the other.

Because it has no way to spread its own pollen on its own.

Because he is typical of the androgynous current.

Because their anthers and stigmas are separated.

The stigma is isolated, so it's hard.

It's just hard to pass on. Because they have teeth.

Very interesting question! Canola pollen doesn't actually pollinate Venus flytraps. Venus flytraps are insectivorous plants that feed on insects or other small animals, and they usually rely on insects to capture insects in their natural environment for the nutrients they need.

Venus flytraps typically have smaller flowers that do not produce pollen or nectar, but are reproduced by pollination by bugs.

When an insect touches the tentacles or tentacles of the flytrap, the plant quickly shuts down and traps the insect. The Venus flytrap then releases digestive enzymes to break down the insect to absorb the nutrients it needs. As a result, the Venus flytrap feeds on insects to meet its nutrient needs and does not rely on plant pollination.

However, it is worth noting that some insectivorous plants also produce pollen and nectar to attract other insects to pollinate. Different species of insectivorous plants differ in their pollination strategies.

Canola pollen cannot pollinate Venus flytraps. This is because rape pollen is collected by bees and other insects, while Venus flytrap Zen Kuanji is pollinated by self-pollination (self-pollination), so it does not require the help of bees and other insects. Therefore, rape pollen cannot pollinate Venus flytraps.

Summary. Venus flytraps bloom during the summer months.

In fact, strictly speaking, the new leaves bloom soon after they appear in the spring, and they bloom until midsummer.

When the Venus flytrap is in bloom, it usually grows a lot of buds on the flower stem, one every other day. If the flowers are not pollinated, they can open for a few days, but after successful pollination, the flowers will wither the next day.

After the Venus flytrap grows new leaves in the spring, it grows a long flower stem with more than 10 buds, and the flowers are white with five petals when they bloom, and the pollinated flowers will bear fruit when they wither.

Venus flytrap is a very amazing plant that can get the nutrients it needs by attracting and devouring insects. When the Venus flytrap blooms, many people don't know what to do with it. Here are some ways to deal with Venus flytraps after flowering.

First, cut off the flower stems. When the flytrap produces flowers, the flower stems will grow very tall. In order to avoid affecting the growth of the Venus flytrap and consuming its energy, we can cut off the flower stems. This allows the flytrap to focus on growing and absorbing nutrients.

Second, collect pollen. If you want to try to propagate flytraps, you can collect pollen. Pollen can be obtained by crumpling the flowers and collecting the pollen grains in them. You can then place pollen on the flowers of other Venus flytraps to promote fertilization.

Third, leave the flowers. Although the main function of Venus flytraps is to prey on insects for nutrition, they also produce beautiful flowers. So, if you like the flowers of the flytrap, you can choose to keep them and appreciate their beauty.

Fourth, cut off the flowers. If your Venus flytrap grows indoors or needs to control its growth, you can cut off the flowers. This prevents the flowers from continuing to consume the plant's energy, allowing the plant to focus more on absorbing nutrients and growing.

All in all, when the Venus flytrap blooms, we can dispose of them by cutting off the flower stems, collecting pollen, leaving the flowers, or cutting off the flowers. These methods can help us control the growth status of the flytrap or promote reproduction to maintain the healthy growth of the plant.

The flowering Venus flytrap is a type of vascular plant and is a popular insectivorous plant with complete roots, stems, leaves, flowers, and seeds. Its leaves are the most important and obvious part, which has the function of preying on insects, with obvious stinging hairs and red sessile glands, which look like a bloody mouth with teeth and claws. Potted plants can be used for sunny windowsills and balcony ornamentation, can also be specially planted trough culture, Venus flytrap is known as a carnivorous plant in nature, flowering period from May to August, fruiting period from October to November.

Cultivation techniques. Planting requirements.

Light: swampy plants, native environment without the shade of tall plants, like the sun. When cultivating at home, spring, autumn and winter can be full sunshine, and in the southern summer, 50% shade should be added or placed on the indoor sunny window sill.

Or use a plant fill light (red-blue ratio 2:1) to carry out artificial light cultivation at a distance of 15-30cm above the plant, and the irradiation time is 4 hours.

Moisture: Use soft water such as purified water and rainwater as much as possible (tap water can be used in southern China). With the basin dipping method (called in Hong Kong and Taiwan"Waist fluid"law) to create a small environment similar to the native place, by doing the following:

Place the Venus flytrap pot in a tray or glass jar, fill it with water to a depth of 1-2 cm, and replenish it regularly. (Note: Waist water is easy to rot roots in summer).

Humidity: more than 50%, the native environment of the flytrap is a swampy grassland, the humidity is relatively high, if you can use a large water pan to make waist water, the humidity near will be a little higher, you can also add a layer of water moss to the topsoil of the pot, which is also helpful to maintain air humidity.

Substrate: The substrate remains acidic. Peat with no added fertilizer and perlite 2:1 or pure water moss, the substrate is best changed once a year.

Temperature: 15 35 for growth, 21 35 for growth, 21 35 for growth, and if you want to make it dormant in winter, it must be controlled at about 5 (0 8). However, based on years of conservation experience, the absence of dormancy has no significant effect on normal growth in the following year.

Feeding: Please don't force them to eat too much, they will prey on their own. Arthropods (insects, spiders, etc.) should only be fed on a maximum of 2 leaves. Their digestive juices have a hard time digesting the fats in meats that people consume every day, such as beef and chicken.

Fertilization: The roots of insectivorous plants are extremely intolerant to salt, and direct application of fertilizer into the substrate will lead to the death of the plant, so foliar sprays of trime foliar fertilizer should be applied every 2 weeks during the growing season.

Venus flytraps are perennial herbaceous plants. After the seed germinates, it takes 4 to 5 years to reach maturity before flowering and fruiting. With good care, Venus flytraps can live for at least 20 to 30 years.

Venus flytraps begin to bloom shortly after they develop new leaves in the spring, and they produce a flower stem that is 15 to 25 cm tall and has about 10 flower buds at the tip. It blooms every other day and is white in color. A flower can bloom for a few days before pollination, but if pollination is successful, the flower will be extinguished the next day, after which the ovary will slowly expand and the fruit will ripen after a few weeks.

The ripe fruit contains dozens of black, droplet-shaped seeds, and after flowering, the Venus will continue to grow more leaves and grow larger insect traps, which is the season when the Venus needs to hunt a lot of nutrients for the next year's flowering. The fruit that bears fruit at the end of spring ripens in mid-summer, and the seeds that are sown germinate over time. The first leaf of the young Venus flytrap has a complete insect trap and begins to live a life of catching insects.

The leaves of the Venus flytrap live for about a few weeks, the old leaves will gradually turn yellow, lose their ability to catch insects, and finally turn black and die, but the new leaves will continue to grow from the center. Throughout the summer, the flytrap will continue to grow new leaves until autumn, when another slower-growing leaf grows, at which point the summer leaves are so large that they have withered and the flytrap is ready for winter. In winter, some insect traps are still there, but they have lost their ability to catch insects and are hardly used. When the climate is too cold, the leaves on the ground will wither.

When spring comes, the temperature rises, and the flytrap pulls out new leaves again and starts a new life.
