Why are roses red
Firstly, it has its material foundation. Both safflower and red leaf contain anthocyanins converted from glucose in their cell sap. When it is acidic, it appears red, and the stronger the acidity, the redder the color. When it is alkaline, it appears blue, with strong alkalinity, becoming blue black, such as chrysanthemums and black peonies. When it is neutral, it is purple.
Explain using the principles of physics. The sunlight, refracted by a prism or water droplet, is divided into seven colors: red, orange, yellow, green, blue, blue, and purple. These seven colors have different wavelengths of light, with red light having shorter wavelengths and purple light having shorter wavelengths. Acidic anthocyanins will reflect long red light waves and send them to our eyes, making us feel bright red flowers. Similarly, neutral anthocyanins reflect purple light waves, while alkaline anthocyanins reflect blue light waves.
Its physiological needs. The length of the light wave varies, and the amount of heat it contains also varies: the wavelengths of red, orange, and yellow light contain more heat; Blue and purple light waves are short and contain less heat. The tissue of flowers, especially the petals, is generally relatively tender. In the wild, red, orange, and yellow flowers all grow in areas with strong sunlight, reflecting long light waves with high heat content, which does not cause burns and has a protective effect. Blue flowers grow under trees and in grass, reflecting short light waves and absorbing weak long light waves with high heat content, which is beneficial for their physiological functions. White flowers are also mostly shade plants, some of which open at night and reflect all the light waves, which is another adaptation measure. There are few black flowers in nature, and only a few flowers occasionally have black spots because black absorbs all light waves and generates too much heat, making them vulnerable to damage.
In the West, roses represent loyal and pure love, and red roses in flower shops are the best-selling. Men are all vying to buy to give to the person they like. In recent years, with the westerly wind moving eastward, the practice of sending red roses to express admiration has gradually become popular in China. Why choose a red rose to express love? This is related to an ancient myth. In Greek mythology, the goddess of love, Aphrodite, was as beautiful as a celestial being, surpassing all women in heaven and earth, and became the object of most gods’ admiration and pursuit. Even Zeus fell in love with her at first sight, but was rejected by Aphrodite. Zeus harbored a deep hatred and married her to the ugly and lame god of fire, Hephaestus. The appearance of the Fire God is really ugly, even his mother, Queen Hera, hates it very much. But Aphrodite did not love the god of fire, she fell in love with the beautiful human boy Adonis.
Adonis was very fond of hunting, and Aphrodite was worried that he would suffer misfortune. He advised him many times not to go, but Adonis did not listen. Once, while he was out hunting, a fierce wild boar suddenly burst out in the forest in the mountains. Adonis was caught off guard and the wild boar bit off his great artery in the foot, spraying blood and falling to the ground. Aphrodite heard Adonis’s screams from afar and was extremely anxious, running to rescue her lover at all costs. The valley was filled with white roses, and thorny roses cut through her feet, legs, and hands, spilling blood all the way.
But Adonis still died, and the white rose stained with the blood of Aphrodite later bloomed into a red flower, becoming a red rose. Due to the beautiful and touching legend of the origin of the red rose, it is regarded as a symbol of love by people. Of course, roses of other colors are also very symbolic, with red roses representing passion and true love; The yellow rose represents cherishing blessings and jealousy, as well as heartbreak; Purple roses represent romantic truth and precious uniqueness; White roses represent purity and innocence; Black roses represent tenderness and sincerity; Orange red rose friendship and youthful beauty; Blue roses represent honesty and kindness. And how many flowers to give also has meaning; For example, a rose represents – in my heart, only you are ONLY YOU; 11 roses represent – favorite; 99 rose symbols – Forever for eternity; 108 roses symbolize marriage proposal.
After reading it, do you think this flower is more meaningful as a gift? However, roses are not only a flirtatious gift, but also have medicinal value such as reducing fire and qi, nourishing yin and beauty, regulating blood and qi, and enhancing beauty. They can also eliminate fatigue, protect liver and gastrointestinal functions, and long-term consumption can promote metabolism. They are often used for other purposes.
For example, in a rose bath (after breaking off the bought rose petals, rinse them with cold water 2 to 3 times, boil them in water for 10 minutes, filter out any residue, and mix with the bath water), rose tea (soak dry rose petals with tea leaves in boiling water at 80 to 90 degrees Celsius for 5 minutes to drink), rose vinegar (prepare a bottle of white vinegar, some dry roses, open the white vinegar, put the rose petals in, and discard the rest. Put it in about one-fifth, cover the lid [remember to seal], and place it in a cool place for about 5 to 6 months), and can also be used as a delicacy, etc., provided that there is Only dried rose petals can be made.
