The loofah flower is not a unisexual flower10

Most of the loofah flowers are unisexual, that is, male and female flowers are produced on the same plant. In general, male flowers occur first, followed by female flowers.

The flowering time of male and female flowers is after the dew is dry every morning, from 7 a.m. to 9 a.m. on sunny days, and after 10 a.m. on rainy days when the humidity is high and the temperature is correspondingly low. The flowering period is short, and the corolla naturally withers after 24 hours, and the stigma turns brown, gradually losing its ability to germinate and pollinate. One day before the anther opens, the pollen grains have the ability to germinate, and they can be pollinated and fertilized.

However, the most fertile period is when the corolla is in full bloom, and it is important to take advantage of this opportunity when it comes to artificial pollination or hybridization. The occurrence of male and female flowers of loofah has a certain regularity, which is closely related to its variety attributes, and generally the male flowers are differentiated earlier and are born on the lower nodes of the plant. The female flowers are differentiated late, the nodes are higher, and the general early-maturing varieties are born on the axils of 4-5 leaves, and the mid-late varieties are born on the axils of 8-9 leaves. In addition, the node position of female flowers is related to temperature and light.

According to the situation of loofah seedlings in winter in recent years, the early and medium-maturing varieties are under the condition of low temperature and short day, and the female flower node position is reduced, and the early-maturing varieties can produce female flowers in 2-3 nodes, and the medium-maturing and late-maturing varieties can also have female flowers in 4-5 nodes. When cultivating and managing, the early management should be based on preventing loofah from falling seedlings.

Shed cultivation, small ventilation in winter and spring, relatively high air humidity, late opening time of male and female flowers, late release of anthers after flowering, pollination should be appropriately postponed to make effect. In addition, when the temperature is too low, the male flowers have no pollen, so they need to be treated with hormones and smeared flowers to promote fruit set.

Excerpt from: The interactive encyclopedia "Luffa Flower".

The loofah flowers are mostly unisexual.

No, like cucumbers, each flower can produce loofahs.

Yes, there is a small loofah under the female flower of the loofah, and the male flower does not.

Be. Melons are unisexual flowers.

Yes, the loofah is monoecious.

Do loofah flowers belong to unisexual flowers.

The loofah flower belongs to the unisexual flower, because there will only be a pistil or stamens in a loofah flower, and it will not have it at the same time, so it belongs to the brother Bu unisexual flower, the loofah is to bloom before bearing fruit, and the loofah flowers are bright yellow, the petal shape is generally oval-oval, and there are clear veins in the middle of the petals, and the edges are relatively curved.

Are the loofah flowers monoecious?

The loofah is a common vegetable in summer, the loofah can bloom and bear fruit, so the loofah belongs to the angiosperm plant, not gymnosperms or angiosperms, and the loofah flower is also a monoecious vegetable.

Loofah flower flowering time.

The inflorescence type of the loofah flower belongs to the raceme, the inflorescence stalk is relatively thick, there will be 12 cm long, the loofah flower will generally open around July every year, that is, it will bloom in summer, the opening time of the single flower is only two hours, the flowering time is relatively short, and it will wither at night.

Loofah flower pollination.

The main pollination method of loofah flowers is cross-pollination, the color of loofah flowers is bright and fragrant, and it can also be pollinated with the help of bees, so the loofah flowers belong to the insect flower, and then blind dust fiber to the loofah artificial pollination, generally in the morning, as long as the pollen on the male flowers is evenly dotted on the female flower column that opens on the same day.

Loofah flowers bloom**.

Do loofah flowers belong to unisexual flowers.

The loofah flower is a unisexual flower, because only pistils or stamens can be found in a loofah flower, so it is a unisexual flower. The loofah flowers are usually bright yellow in color, and the petals are generally oval in shape, with clear veins in the middle leaf and curved edges.

Are the loofah flowers monoecious?

Loofah is a common vegetable in summer. The loofah can either flower or bear fruit, so the loofah belongs to a subclass of plants and not gymnosperms or angiosperms. In addition, loofah flowers are also vegetables that are changed from female to male and female.

Loofah flower flowering time.

The inflorescence type of the loofah flower belongs to the raceme, and the peduncle is relatively thick, and it will be 12cm long. The loofah flowers generally bloom around July every year, that is, in summer. The flowering time of a single multi-flower is only two hours, and the flowering time is relatively short, and it usually withers in the evening.

Loofah flower pollination.

The main method of pollination of loofah flowers is cross-pollination. The loofah flowers are bright and fragrant in color and can also be pollinated by bees. Therefore, loofah flowers belong to insect vector flowers.

When the loofah is pollinated manually, it is usually done in the morning, as long as the pollen on the male flowers is evenly distributed on the female flowers that bloom that day.

Loofah flowers bloom**.

The shape of the female flower and the male flower of the loofah is different, the female flower is solitary, the peduncle is 2-10 cm long, the ovary is cylindrical, the male flower is born in the upper part of the raceme, the peduncle is 12-14 cm long, when cultivating the loofah, each watering should ensure that the soil is moist environment, the growth cycle can be applied 2-3 times of fertilizer, the fertilizer is mainly urea, if pests are found, they should be removed in time, and sprayed with insecticides.

The shape of the female and male flowers of the loofah is different, the female flowers are solitary, the peduncle is 2-10 cm long, the ovary is cylindrical, the male flower is born in the upper part of the raceme, the peduncle is 12-14 cm long, which is longer than the female flower, the corolla is yellow, the diameter is 5-9 cm, and the filament is 6-8 mm long.

In the process of cultivating loofah, receive an appropriate amount of light every day to promote the production of photosynthesis, so as to play the growth of loofah and improve the fruit hanging rate. Each watering should ensure that the soil is moist and moist, and the fertilizer can be applied 2-3 times during the growth cycle, and the fertilizer is mainly urea.

In the process of growth, the loofah is easy to suffer from the invasion of pathogens, resulting in yellowing of the leaves, the phenomenon of long spots, during the breeding period to regularly cut off the diseased leaves, spray fungicide to prevent and control, if pests are found, it is necessary to remove in time, and spray insecticides.

Cucumber flowers are basically vestigial axillary unisexual flowers, the inflorescences degenerate into flower clusters, and each flower has sepals, corolla, nectar glands, stamens and primary protrusions at the beginning of differentiation. But after the sepals and corolla are formed, the pistils degenerate, and male flowers are formed; When the stamens degenerate, a female flower is formed; When both the stamens are developed, the flowers of both sexes are formed. Male flowers often have multiple axillary flowers, and female flowers have single or multiple axillary flowers.

Corolla bell-shaped, 5-lobed yellow. Female flower ovary inferior, 3

Chamber, lateral membranous placenta, columella short, stigma 3-lobed. There are 5 stamens, forming three groups in parallel to form a cylindrical shape. Insect-borne flowers, with a natural hybridization rate of 53 76%.

Cucumber flowers usually bloom from 5:30 to 6 o'clock, the flowering time is 1 hour, the life span of the flowers can be delayed until the afternoon of the same day, the male flowers fall off the next day, and the life span is longer in low temperature and rainy weather, and the next day can still bloom normally. When the corolla is complete, that is, when the anthers are prescribed. Pollen, on the other hand, has the ability to germinate in the afternoon of the day before flowering, but the germination ability is at its highest when the medicine is prescribed.

The lifespan of pollen in the natural state is 4 to 5 hours after prescribing the drug, and the lifespan is short when the temperature is high. Cucumber flowering and prescribing are closely related to temperature, and the higher the temperature within a certain range, the more it can be promoted. Generally, it begins to bloom at 15, and begins to prescribe medicine around 17, and the appropriate temperature of the two is 18 21, and the following flowering and prescribing stop.

The temperature limit for pollen germination is between 10 35, and the optimal temperature is 17 25. Cucumbers can reach 2 3 mm in pollen tubes 4 to 5 hours after pollination

Cucumbers are basically monoecious and have bisexual flowers. According to the sex of the flowers on cucumber plants, they are mainly divided into the following seven sex types:

1) Fully flowered plants.

All the flowers on the plant are fully flowered and can fertilize and bear fruit on their own.

2) Female strains.

All the flowers on the plant are female.

3) Male strains.

The flowers of the whole plant are male and have no production value. It can only appear in exceptional circumstances.

4) Monoecious.

There are female and male flowers on the plant, and the number of male flowers is often more than that of female flowers, which is a standard type.

5) Female and homogeneous.

There are female flowers on the plant, and there are also complete flowers, and this plant can fertilize and bear fruit on its own.

6) Male and all homogeneous.

The plant has both male and complete flowers, so it can also fertilize and bear fruit on its own.

7) Monoecious.

The plant has female, male and complete flowers, and can fertilize and bear fruit on its own.

It belongs to incomplete flowers.

According to the structure of the flowers, flowers can be divided into two categories: complete flowers and incomplete flowers. In a flower, the calyx, corolla, stamens, and pistil are all four, which is called a complete flower, such as cabbage closed hail flowers, attack peach blossoms; Missing one to three of these parts is called incomplete flowering, such as pumpkin flowers, cucumber patted flowers, lack stamens or pistils.
