Tulip is famous for its beautiful and changeable shapes and rich colors. There are more than one color in many tulip cup-shaped flowers. The reporter of Yangzi Evening News saw that the flower of "Claudia" is purplish red, but the "cup mouth" is inlaid with white lace like lace. And green "Prince Klaus" petals, lace is rose red. How is tulip beautiful lace formed? Let's have a look with 360 common sense.
The color of tulips changes when they cross
The color of tulip flowers is determined by the composition of different pigments in the flowers and the proportion between them. At present, there are more than 500 kinds of pigments in the known tulip varieties. The Yellow varieties only contain carotenoids, while the orange varieties contain at least carotenoids and anthocyanins. The petals of red varieties contain anthocyanin and anthocyanin, the petals of purple varieties contain anthocyanin and anthocyanin, the petals of pink varieties contain a variety of pigments, but the pigment content is lower, while the flowers of white varieties contain almost no pigment.
According to some data, in order to study the genetic law of tulip pigment, a lot of experiments have been done by researchers. In one experiment, a large number of parents of tulip were crossed and 1000 seedlings were obtained. After cultivation, 21 color groups were obtained. There are monochromatic and polychromatic groups in these groups. Then, the researchers compared different groups of pigments and genetic background analysis found that it is not feasible to predict the color of hybrid flowers through the color of their parents. That is to say, if white tulips and white tulips are used for hybridization, the offspring may not be white, but red or other colors.
"Lace" may be a mutation of seed ball gene
As for the appearance of "lace", Li Mei said, it may be a gene mutation from tulip bulbs. It is reported that mutation can change the color and flower type of tulips. For example, a single color can change into edge coloring or variegation, and the flower shape can change into Parrot Tulip, edge decoration or double tulip. Many popular tulip varieties are artificially induced mutation by radiation treatment of seed ball. In addition, the reporter of Yangzi Evening News learned that in addition to the artificial induced mutation, there is also a possible "pathological change" of tulip itself. For example, the golden peach leaf coral is a kind of peach leaf coral, but aphids carry a virus to erode the peach leaf coral, resulting in yellow spots on the leaves, "golden" from this. The virus caused its genetic variation. Unexpectedly, the "spot" turned out to be a stable heredity, and the "golden peach leaf Coral" appeared.
Tulip represents sanctity, happiness and victory. Red tulip represents the declaration of love; black tulip represents mystery, nobility and chivalry; purple tulip represents noble love and endless love; white tulip represents pure love and purity; yellow tulip represents elegance, precious, wealth and friendship.
When do tulips bloom
Tulips bloom at different times, some earlier, in early March, and later to the end of April, the flowering time is short, usually more than ten days. According to the latitude of the growing area, the flowering period is also different, generally from late March to early May, and the flowering time of tulips is around 8 a.m.
What is the flower language of tulip
Tulip implies elegance, wealth, ability and intelligence. Tulip flower language is the expression of love, charity, reputation, beauty, blessing, eternity, love and eternal blessing.
郁金香原产沿岸及中亚细亚、土耳其等地。由于 的 ，形成郁金香适应冬季湿冷和夏季干热的特点，具有夏季休眠、秋冬生根并萌发新芽但不出土，需经冬季低温后第二年2月上旬左右（温度在5℃以上）开始伸展生长形成茎叶，3～4月开花的特性。生长开花适温为15～20℃。花芽分化是在茎叶变黄时将鳞茎从盆内掘起放阴冷的室外内度夏的贮藏期间进行的。分化适温为20～25℃，最高不得超过28℃。
Tulip originated in Mediterranean coast, Central Asia, Turkey and other places. Because of the Mediterranean climate, tulip is suitable for cold and humid winter and hot and dry summer. It has the characteristics of dormancy in summer, rooting in autumn and winter and sprouting new buds but not unearthed. It needs to start to grow and form stems and leaves in the first ten days of February in the second year after low temperature in winter (the temperature is above 5 ℃), and blossom from March to April. The suitable temperature for growth and flowering is 15-20 ℃. Flower bud differentiation is carried out during the storage period when the bulbs are dug up from the basin and put out in the cool outdoor environment when the stems and leaves turn yellow. The suitable temperature for differentiation is 20-25 ℃, and the highest temperature should not exceed 28 ℃.
Tulip is a kind of long sunshine flower. It is sunny and windward. It is warm and humid in winter and cool and dry in summer. Above 8 ℃, it can grow normally and can withstand - 14 ℃ low temperature generally. The cold resistance is very strong. If there is thick snow cover in the cold area, the bulbs can live through the winter in the open, but they are afraid of the heat. If summer comes early and the midsummer is very hot, the bulbs are difficult to survive after dormancy. It is required that the loam with rich humus, loose and fertile soil and good drainage should be made. Avoid alkaline soil and continuous cropping.
