Why do scented flowers smell stronger after rain?

Because when it is not raining, there are more dust and other microparticle molecules in the air, and our nasal cavity inhales too much dust, and the smell is lighter! And when it rains, it can play a role in reducing dust and refreshing the air! Raindrops pour down from the clouds, crushing down and converging the dust particles that are rising from the ground, and the dust particles in the air are also pressed down by the raindrops, and the air becomes fresher and more sensitive to smells.

1. After the rain, the petals are rinsed clean, the air is fresh, and the fragrance of the flowers does not need to penetrate the haze, and with the wind, it directly enters the person's nasal cavity!

Second, after the rain, the humidity in the air increases, and when the humidity is higher, the fragrance of flowers will be stronger! <>

Third, when the flowers are wet by the rain, the dried pollen will volatilize into a stronger floral fragrance through the infiltration of the rain, just like the tea leaves are moistened by water, and they will exude a rich fragrance!

Therefore, it is a very good choice for everyone to go out for a walk and play after the rain. Not only will people's mood become comfortable because of the fragrance of flowers and the freshness of the air, but also the fragrance of flowers has many effects. <>

Our common osmanthus fragrance is refreshing and can reduce fatigue; The fragrance of crape myrtle and osmanthus has a bactericidal effect. The smell of osmanthus is sweet and fragrant, and the comprehensive components in its floral fragrance can play a certain role in Alzheimer's disease and also have auxiliary effects on regulating blood pressure. For patients with bronchitis, smelling more cinnamon can reduce pain.

After the rain, the humidity of the air increases, and when the temperature is higher, the floral fragrance is stronger.

That's when the air is fresher after the rain and it's easier to spread the scent.

Because the fragrance is stronger in the humid air.

Because of the rain, all other impurities were washed away.

Because they are pollinating more after the rain.

Because it can spread the taste through moisture.

I don't think it's that the flowers are more fragrant, it's that the other flavors are weaker.

That's when it's easier to spread the smell after the rain.

It's also a way to survive.

Because the flowers contain Huixin, there are oil cells that can continuously secrete aromatic oils. Aromatic oils are volatile easily, especially during the day, when the flowers are heated by the sun and give off a fragrance.

The colorful flowers make you love, and the fragrance of the flowers is even more refreshing. The fragrance of the flower comes from the petals. This is because the petals contain oil cells, from which aromatic oils with fragrance can be secreted.

With the moisture, the aromatic oil evaporates into the air, so the thick aroma wafts around in the air.

Blossoms. Flowers, flower [.]'flau] inflorescence, refers to a flower that has already opened. It mainly refers to the petal part, which is bright and beautiful; It is mostly used for children, symbolizing beauty, purity, and hope.

Flowers will emit fragrance because the petals contain oil cells and glycosomes, oil cells will continue to secrete volatile and aromatic aromatic oils, which can make people smell the aroma, while the glycosomes themselves have no aroma, but after enzyme decomposition, they will emit the smell of fragrant sunchildren, and flowers can attract insects for pollination through aroma.

Flowers will emit fragrance because flowers contain two substances, glycosomes and oil cells, of which glycosomes will emit aroma after being decomposed by enzymes, and it has no fragrance itself, while oil cells will continue to secrete aromatic oil with aroma, and aromatic oil is easy to volatilize.

Flowers and plants will emit different fragrances in order to reproduce, because the fragrance can attract insects who like this fragrance, insects will stay on the stamens will be contaminated with pollen, waiting for insects to fly to other flowers, you can achieve the purpose of pollination, guess the luck so that the flowers bear fruits and seeds.

The aroma of different flowers is different, because the flower plants have different ability to decompose glycosomes and secrete aromatic oils, resulting in a strong aroma of some flowers, and a light aroma of some flowers, generally speaking, white and yellow flowers have the strongest aroma, while blue and purple flowers have the lightest fragrance.

When growing flowers, they need to be placed in a ventilated environment to avoid discomfort, and in spring and winter, they need to receive all-weather natural light to promote photosynthesis, and in the middle of summer, they need to be shaded.

1.Flowers have fragrance because there is aromatic oil in front of Wang Min in the flower, and the volatilization of aromatic oil in each flower is different, so the fragrance is not the same.

2.There are also flowers that do not have aromatic oils, but they will produce aromatic oils during the metabolic process, and they will also emit fragrance.

3.Some flowers such as roses and jasmine have a strong fragrance and are sleepy because the degree of volatilization of the aromatic oil in them is relatively large.

The flower (hua) (executed) is the sexual reproductive organ of the seed plant (see color map). Typical pre-flower, on a limited short term, has the stamens and pistils of the flower wind, petals, and germ cells. The flower is composed of a corolla, a flower guess, a flower back, and a stamen.

There are various colors, some are beautiful, some are fragrant. So why do flowers have fragrance? There is an oil cell in the petals that constantly secretes aromatic oils with a fragrance.

Because the aromatic oil evaporates quickly, it exudes a refreshing fragrance. When the flowers bloom, the aromatic oil will be emitted along with the water, and this is what people smell of flowers! Because all kinds of flowers contain different aromatic oils, the fragrance emitted is also different, some are strong, and some are elegant.

There are also some flowers in nature, and although there are no oil cells in the petals, they smell like a burst of fragrance. It turns out that their cells contain something called a glycopeptide, which also produces aroma after the enzyme breaks down. The different meaning of u0004 is that when the sky is sunny and the temperature rises, the aromatic oil in the petals volatilizes faster and drifts farther, so the smell will be stronger.

However, some flowers that bloom at night, such as nightshade and Milan, will have a stronger fragrance due to the higher the air temperature, the larger the stomata will expand. As a result, their aroma at night will be purer and stronger than during the day. Knowledge Expansion:

Flowers are seed plants that are sexual reproductive organs (see color figure). Typical flowers grow the petals and petals of male and female germ cells on a short axis of limited growth. The flowers are composed of a corolla, petals, a receptacle, and a flower room.

The flowers come in a variety of colors, some grow beautifully, and some are fragrant. Why is the aroma so good? The fragrance of the flower comes from an oily cell in the petals, which constantly secretes aromatic oils, which are made up of a chemical called aromatic oil.

When the flowers bloom, the aromatic oils will be emitted along with the water, which is what people smell as floral fragrances, because aromatic essential oils are easily volatile. Since each flower contains different aromatic oils, the aroma emitted is also different. There are also some flowers in nature, although there are no oil cells in their petals, but they still smell fragrant, because these flowers contain a lot of fatty acids, which can improve the body's immunity and also help the body resist the invasion of viruses.

It turns out that their cells contain a substance that, when broken down by enzymes, also produces a scent, which is made up of a substance called a glycopeptide. Generally speaking, when the weather is sunny and the temperature rises, the aromatic oil in the petals volatilizes faster, and the fragrance of the flowers drifts farther away, so the fragrance will be stronger, and if the weather conditions are bad, the fragrance will be a little stronger. Since the higher the air temperature, the larger the pores of the petals open and the more aromatic oils volatilize, so they emit a purer and stronger fragrance at night than during the day, so some flowers (such as nightshade, Milanese, etc.) bloom at night.

The reason why some flowers emit fragrance is because the petals contain oil cells, which can secrete various aromatic oils, which are called essential oils and are volatile. When the essential oil molecules evaporate, people smell the aroma. Due to the different chemical composition of the essential oils contained in different types of petals, different types of flowers emit different aromas.

Such as white orchid, jasmine aroma; Orchids and gardenias are fragrant, and roses and osmanthus are fragrant; Milanese, tuberose has a strong aroma; The aroma of plum and narcissus is elegant; The smile is sweet and fragrant. Different aromas will cause different reactions to people, and the same floral fragrance will feel different people.

The fragrance of the flower does not emanate from the core, but from the petals. There is an oil cell in the petals that constantly secretes aromatic oils with fragrance. Because aromatic oils volatilize easily, when the flowers bloom, the aromatic oils will be emitted along with the moisture, which is what we smell as floral scents.

It's not the same, some are stimulating, some are disgusting.

The aroma that people smell is often composed of a variety of aromatic compounds in the mountains. For example, the aroma of jasmine is made up of more than 80 chemical components, and the aroma of rose is made up of more than 280 compounds. In the production of spices, the different aromas emitted by different fragrant flowers are often determined as various fragrance types, such as white orchid type, jasmine fragrance type, gardenia fragrance type, rose tree type, etc., and the petals of different tree types are processed to extract different types of spices for cosmetics and food industry.

Among the many flowering plants, which flower color has the most fragrant flowers Some people have identified more than 4,000 flowers of different colors, and among the 1,265 kinds of white flowers, fragrant flowers account for 20%; Among the 922 species of safflower, fragrant flowers accounted for 17%; Among the 954 species of goldenrod, fragrant flowers accounted for 14%; Of the 600 species of blue flowers, fragrant flowers account for 9%, and among the 309 species of purple flowers, fragrant flowers account for 13%. From the above statistical results, it can be seen that the proportion of fragrant flowers is the largest among the white flowers, followed by red and yellow, and the fragrant flowers are the least among the blue flowers.

In order to attract animals to pollinate them, some will evolve bright and dazzling flower colors, and some will evolve a fragrant fragrance to attract flying insects to pollinate them.

The reason why flowers are scented is because there is a secretory tissue of oil cells in the petals, which can secrete aromatic oils.

This is the normal physiological characteristic of flowers, so each flower has its own unique floral fragrance, and this kind of portrait will bring great joy to people, and it will also make people very happy.
