Tulip is famous for its beautiful and changeable shape and rich flower color. Many tulip cup-shaped flowers have more than one color. Yangzi Evening News reporter saw that the flower of "Claudia" is purplish red, but the "cup mouth" is inlaid with white lace like lace. But the green "Prince Claus" petals, the lace is rose red. How does tulip's beautiful lace come into being?
Tulips change color when they cross
The color of a tulip flower is determined by the composition of different pigments in the flower and the proportion between them. At present, there are as many as 500 kinds of pigments in the known tulip varieties. The petals of yellow varieties only contain carotenoids, while the petals of orange varieties contain at least carotenoids and anthocyanins. The petals of red varieties contain anthocyanins and anthocyanins, the petals of purple varieties contain anthocyanins and anthocyanins, pink varieties contain a variety of pigments, but the pigment content is lower, and the flowers of white varieties contain almost no pigment.
Some data show that in order to study the genetic law of tulip pigment, researchers have done a lot of experiments. In one experiment, 1000 seedlings were obtained by crossing a large number of parents of tulip. After cultivation, 21 color groups were obtained. In these populations, there are monochromatic and polychromatic populations. Then, the researchers compared the pigments of different populations and analyzed the genetic background, and found that it was not feasible to predict the flower color of hybrid offspring by the color of their parents. In other words, if you cross a white tulip with a white tulip, the offspring may not be white, but may be red or other colors.
"Lace" may be a mutation of bulb gene
For the appearance of lace, Li Mei said it might be a genetic mutation from tulip seed balls. It is reported that mutation can change the color and flower type of tulip, such as single color can be changed into edge color or variegation, and flower shape can be changed into Parrot Tulip, edge decoration type or double petal tulip. Many popular tulip varieties are induced by radiation treatment of seed balls. In addition, Yangtze Evening News reporter learned that in addition to artificial induced mutation, there is also a possible tulip itself a "disease.". For example, golden peach leaf coral is one of the peach leaf corals, but aphids carry a virus to erode the coral, causing yellow spots on the leaves, and "sprinkling gold" comes from it. The virus caused its genetic variation, and did not expect that "spots" turned into a stable genetic, and "golden peach leaf Coral" appeared.
Tulips represent holiness, 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 feeling and purity; yellow tulip represents elegance, precious, wealth and friendship.
When do tulips bloom
The blooming time of tulips is uneven. Some of them are early and bloom in early March, while the later ones will bloom at the end of April, and the flowering time is short, generally more than ten days. In addition, according to the latitude of the growing area, the flowering time of tulips varies from late March to early May, and the flowering time of tulips is around 8:00 a.m.
What is the flower language of tulip
Tulip means elegance, wealth, ability and intelligence. The flower language of tulip is love, charity, reputation, beauty, blessing, eternity, the expression of love and eternal blessing.
Tulip originated from Mediterranean coast and Central Asia, Turkey and other places. Due to the Mediterranean climate, tulip can adapt to the characteristics of cold and humid winter and dry and hot 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 expand and grow in the first ten days of February of the next year (the temperature is above 5 ℃) to form stems and leaves, and bloom from March to April. The optimum temperature for growth and flowering is 15 ~ 20 ℃. Flower bud differentiation is carried out during the storage period when the stems and leaves turn yellow, and the bulbs are dug up from the pot and stored outdoors in the cold outdoor. The optimum temperature for differentiation was 20-25 ℃ and the highest temperature was 28 ℃.
Tulip is a kind of long sunshine flower. It is warm and humid in winter and cool and dry in summer. It can grow normally above 8 ℃ and can tolerate - 14 ℃ in general. It has strong cold resistance. If there is thick snow cover in the severe cold area, the bulb can overwinter in the open field, but it is afraid of extreme heat. If the summer comes early and the midsummer is very hot, it is difficult for the bulb to spend the summer after dormancy. It is required that the slightly acid sandy loam with rich humus, loose and fertile and good drainage is required. Avoid alkaline soil and continuous cropping.
