Whether it is flowers or leaves, their cells contain the glucose in the fluid into the anthocyanins. The time when it is acidic, red, acid stronger, the more red color. The time when it is alkaline, appear blue, strong alkaline,UGGs, becoming blue-black, such as Mo-Ju, Black Peony and so on. The time when it is neutral, it is purple.
there are In addition to other Compositae yellow, more orange flowers. Orange and orange, the color of pumpkin and other fruit similar to the most typical is the carrot, so the performance of this color pigment is called carotene.
As for white, it is because in non-pigment cell sap reason. Some white, the next such as chrysanthemum, fade before the micro-dyed red, that it now also contains a small amount of anthocyanin. A special example is the color add color Hibiscus, opened in early morning, white, pink, noon, afternoon, dark red, day three changes, the more open the more beautiful. Another example is the hydrangea, white, greenish to open early, after a few days, become pale, or with slightly blue, it did not add color Hibiscus down towards the opening evening. As for general spending, most of the early opening when the rich and gaudy, faded after the Jiandan.
In addition, the need to use physics to explain. Sunlight refracted through the prism or water droplets, will be divided into red, orange, yellow, green, green, blue, purple seven colors. This is the length of seven different colors of light, purple wave short. Acid long red light anthocyanin will reverse out to our eyes, we feel is the bright red flowers. Similarly, the neutral light purple anthocyanin reflection, basic blue light reflection of anthocyanins, carotenoids have different components, they are light yellow or orange light reflection. Non-white pigment, but the organization which contains the air, will all the reflected light. Some petals are more subtle surface arranged in neat glass ball-like protrusions, it looks like velvet, can be as strong as the diamond back light, the more vibrant colors, such as some Chinese rose is.
the color of the flowers also its physiological needs. Light waves of different length, calories are also different: red, orange, Huang Guangbo long, containing more calories; blue, purple wave is short, with less heat. Flowers organizations, especially petals, are generally more tender. In the wild, red, orange, yellow flowers grow in a place the sun is strong, reflecting the long-wave with more calories and will not cause burns, there is protection. Blue flowers growing in the woods, the grass, reflecting short-wave, absorbing more calories a weak long-wave, its beneficial physiological effects. Plants white flowers are more negative, and some evening hours, reflecting all the light waves, is another adaptation measures. Little black flowers in nature, only a few flowers with black spots occasionally, because black absorbs all light, excessive heat, vulnerable.
to examine from an evolutionary point of view, it has a development process. Gymnosperms is the original form of the flower, all with green, while the anther and pollen is yellow. Inside of the spectrum, and green adjacent, long-wave end is yellow, orange and red, short-wave end is green, blue and purple. We can say that color green as the starting point at one end to the long-wave development, from yellow and orange, finally red; to the short end of the development is the blue and purple. The red color appears to be is the latest in the evolution of living peak, the most bright and dazzling.
from Darwin's natural selection theory view, insects play an important role. Hundreds of millions of years ago, gymnosperms appeared on the earth when the insects are not many. Fancy Eau, pollination fertilization, relying on Amaranthus force, all wind-pollinated flowers. The subsequent emergence of angiosperms, insects multiplication up. Angiosperm flowers have a perianth, but also differentiated into calyx and corolla (petals perianth and Corolla can be said). The petals are no longer green, but more conspicuous yellow, white or other colors. Great shape, and some students have nectaries, the secretion of nectar, a sweet and some, which become insect flowers.
insect pollination honey, there is a special habits, is often only cover a plant with flowers. This habit will help ensure that the differences between the same kind of plant pollination, reproduction. This can be fixed species characteristics, including flower color. We can imagine that if I had had a plant, reddish color, the more significant of them red flowers, insects susceptible to the attention of the opportunity to get more pollination, after countless generations of selection, in the long history, the insects gave The plant to create a homogenous, significantly, bright red flowers. The role of insects in natural selection, resulting in a variety of different plants, but also caused a variety of colors. Why red flowers
? Eventually, thanks to artificial selection. The slow process of natural selection, need to go through a very long time to show its effect. Greatly accelerate its artificial selection process, in a short time achieved remarkable results. Such as peonies, the outline of the hundreds of millions of years of natural selection causing the original wild species, flowers are univalve, a pink color only. Through artificial cultivation, just from the mid-Northern Song Dynasty (11th century) was a period of time for it, decades of efforts to create a leafy, Chiba (Double), F sub (Fa process), Bingdi other dark red, meat, red, purple, ink purple, yellow, white and dozens of varieties. Again Dahlia, native of Mexico, only eight red petals. Since the Discovery of America after the artificial cultivation began, now has thousands of shapes, colors of different varieties. Another example is the poppy, after training, there are red, yellow, orange, white and various colors, but there has never been blue. The last century, the famous American breeder Po Bank Garden and found a layer of smoke like the petals of the poppy, specially culture, to the beginning of this century, they bred a variety of different shades of blue poppy, the flower Gardening added new varieties.
flower flower type classification 1
1. to have the various parts of the flower or not to sub:
(1) full flower ( complete flower): calyx, corolla, androecium and pistil of the flower cluster all have termed, such as rape, cotton, peaches, tomatoes and other flowers.
(2) imperfect flowers (incomplete flower): the lack of calyx, corolla, androecium, gynoecium group in any part or parts of the flower commonly known as mulberry, pumpkin, willow flowers.
2. to take the symmetry points
(1) actinomorphic flowers (actinomorphic flower): through the center of the flower can be made more than 2 symmetry plane, also known as neat flower (regular flower), such as cotton, peaches, tomatoes and other flowers.
(2) bilaterally symmetrical flowers (zygomorphic flower): through the center of the flower can only make two symmetrical plane, also known as irregular flower (irregular flower), such as beans, pansy, rice and other flowers.
(3) asymmetric flowers (non-symmetry flower): through the center of the flower, flower symmetry plane can not be made, such as the canna flowers.
3.
under the classification of spring flowers flowering time (3-5 months) fry (6-8 months) fall flowers (9-11 months) to spend the winter (December-February) < br>
4. According to the nature of stem Woody
flowers: plum, peach, peony, crabapple, magnolia, wooden pen, Bauhinia, forsythia, Admiralty, lilac, wisteria, spring cuckoo , azaleas, pomegranate, smiling flowers, white orchid, jasmine, gardenia, osmanthus, jasmine, Hibiscus, bloom-free teeth red, bean sprout Liu, camellias, spring.
common herbaceous flowers: Chun-lan, Hong Jin, arrowhead flowers, hyacinth, tulip, violet, snapdragon, chrysanthemum, Changchun, Cineraria, sweet pea, Ciaran, pink, Lycoris radiata, Lotus, aster , water lily, peony, phlox, tuberose, marigold, amaranth, Cymbidium, tuberose, lily of the valley, Cymbidium, flower Ru Chi, Hong Jin, Sinningia, daffodils, blue grass, melon YE Ju, Calceolaria flower, rabbit flower, into the red wax.
5.
classification based on the growth period is from the annual flower planting, growth, flowering, seed set to the aging of death, life within a year of herbal flowers. Most are in the South China annual flower, annual and biennial flower blooming in the ground is not easy. Annual flower planting period is short, usually 2-6 months flowering, after flowering and fruiting will die a natural death, such as pansy, zinnia, cockscomb, a string of red, maidenhair, cosmos, calendula, chrysanthemum and so on. Are positive annual flower plants, planting location must have full sun for proper growth of flowering, if the lack of sunshine, easily lead to poor fertility, leggy and not easily blossom. Annual flower life span is short, but charming brightly flowering, can be used for potted plants, cut flowers or flower bed landscaping, landscape application types can change the seasons turn, bring people fresh,Discount UGG boots, bright, spectacular visual experience.
perennial flower perennial flower is also called, refers to sex in the perennial herb, the flowering beauty of the concept of a perennial plant flower-based. Perennial flower of life can continue for many years, it regardless of whether the flowering shoots, fruit, underground remains of life, can be re-sprout the second year of growth, re-flowering, such as the African impatiens, chrysanthemums, gerbera, watch pineapple class , Shegan, African violet,cheap UGG boots, bird of paradise, firecracker red.
perennial flower in the ornamental purposes, can be used to layout of garden beds can also be potted or cut flowers and flower arranging for materials, especially in the floral material, perennial nature of the clubs are the main source of floral materials, such as chrysanthemums, carnations , Anthurium, baby's breath, gerbera, bird of paradise flowers and stars and so is an important floral materials.
perennial flower has enough positive light like plants, but also loved the soft light in the scattered negative growth of plants. Seasonal temperature changes and the length of sunlight on the growth and flowering of perennial flower effect is extremely obvious, must be managed into appropriate, can be successfully flowering.
perennial flower to flower-based view can be arranged potted plants or garden for floral, green for the home environment, landscape and people's mental and physical transfers and contributions are of great benefit.
plant, also known as trailing vine or vine of a plant's stem, branches can not easily stretch independent,UGG boots cheap, must rely on its winding tendril or vine stem, climb and even crawl to the normal growth of the ground persons, including plants and woody scandent herbaceous trailing plant, divided into climbing of vines, such as melons, Ficus pumila, Verbena and so uncertain with tendrils or aerial roots can be wrapped around something else volume growth. Winding of the vine, such as morning glory, wooden roses Huangcao fish spend more black eel vine, honeysuckle, with its winding stems can grow something else. Creeping of the vine, such as saddle rattan, wicker, Huang Jinju, etc., vine lying on the ground can grow in contact with the ground at the root-prone. Scandent shrub, such as bougainvillea, jasmine, Yunnan Huang Suxin, shine rattan and other plants of the original shrub, but shoot elongation or after the half trailing vine-like, independent growth or stalk growth.
trailing plants in the landscape can be used for flower-flower racks, fences, landscaping or potted plants such as shade sheds, the vine can bloom after climbing scaffolding for the watch, the formation of a cool space underneath the scaffolding can be for open space, its use more special.
of bulbous flowers in the perennial perennial plant, the roots are especially large, into a block or ball, can store nutrients for the germination of flowering are known as According to the shape and location of the mast can be divided into the bulb (such as lilies, Amaryllis drama, Narcissus, tennis flower), bulbs (such as gladiolus, crocus, freesia), tubers (such as Sinningia, Coleus lines, long-barreled flowers), roots (such as Dahlia, Granville), roots (such as canna, red ginger flowers) and so on.
bulbous flowers of different origin based on the growth can be divided into temperate or tropical species. Cool temperate species preferences (such as tulips, hyacinths, daffodils, etc.), South China are difficult to cultivate flowering ball, an annual all imported bulbs, the short-term training and flowering. Tropical species (such as tuberose, tennis flower, Canna) grow well in southern China throughout the year.
the growth cycle of flower bulbs are a common long-term drought habits - sleep. Sleep duration varies by species, about 30-90 days, the sleep of death when the leaf yellow wilt, the nutrients stored in large underground bulbs, but only some species in the dormant period to stop childbearing, there is no obvious dead phenomena (such as Amaryllis , Zephyranthes, purple daring, etc.). To shorten the cultivation period of dormancy, to promote flowering and tidy, often in cold storage method, breaking the bulb dormancy.
