What does the shape of the corolla mean?

Question 1: What does "Corolla" mean? Introduction to corolla

Corolla is the general name of all petals in a flower, located above or inside the calyx, arranged in one or more rounds, with bright colors, relatively thin compared with sepals, similar in structure to sepals and lacking chloroplasts. The bright colors of petals mainly come from colored bodies in cells and anthocyanin pigments (flavonoids) in vacuoles. Petals containing chromophores are often yellow, orange or orange-red; Petals containing anthocyanins often show red, blue, purple and other colors (mainly determined by the pH of cell fluid in vacuoles). The combination of the two makes the flowers of angiosperms colorful and the petals are white when they don't exist. The epidermal cells of petals often contain volatile oil, which makes the flowers emit all kinds of special fragrance. There are often nectaries at the base of petals, which can secrete nectar to attract insects.

Petals are of the same type in many cases, such as buttercup, begonia and peach flowers. Petals have the same shape and size, which is called regular flowers. However, in some groups, petals tend to differentiate obviously. Petals of leguminous plants, such as peas and astragalus, differentiate into flag petals, wing petals and keel petals with different shapes and sizes, and one of the inner petals of Orchidaceae plants is specialized into a large and beautiful lip petal, which is called irregular flower. Some petals extend out of long or short tubular protrusions, called spur, such as viola yedoensis, aquilegia, impatiens and so on. Some plant petals are divided into limb petals and claw petals, that is, the upper part of the petals expands to form limb petals, and the base of the petals narrows to form claw petals, such as carnation and rape flowers. Sometimes petals become special honey leaves and lose their original shape, such as the petals of Aconitum plants. In the flowers of some plants, there is an additional petal-like or crown-like accessory structure between the petals and stamens, which is called the crown, such as the flowers of milkweed and narcissus.

Similar to sepals, petals may separate from each other or combine with each other. Flowers with separated petals are called petal flowers, such as roses and angelica. A flower with petals closed is called a closed flower, the closed part is called a corolla tube, and the separated part at the upper end is called a lobe, such as Petunia and Salvia miltiorrhiza.

The differences in the shape, arrangement and combination of petals often make corollas form various specific shapes, which become the obvious characteristics of some taxa and have identification significance.

Corolla type

The following are some common corolla types (Figure):

Cruciform: Petals 4, with claws, are arranged in a cruciform pattern (claws stand upright, eaves spread in a cruciform pattern), which is a typical corolla type of Cruciferae plants, such as February blue and Isatis indigotica.

Butterfly: 5 petals arranged in a shingle shape, with the largest one on it, called the flag petal; The two pieces on the side are usually smaller than the flag petals and have different shapes from the flag petals, which are called wing petals; The lower edges of the bottom two pieces are slightly close, like a keel, called a keel flap. Common in leguminous plants such as astragalus, licorice, Sophora flavescens and so on.

Lip shape: the lower part of the corolla is cylindrical, and the upper part is open to one side like a lip. The upper lip is often 2-cleft, and the lower lip is often 3-cleft. Common in labiatae plants such as mint, scutellaria baicalensis, salvia miltiorrhiza, etc.

High-legged dish: the lower part of the corolla is combined into a long and narrow cylinder, and the upper part suddenly spreads horizontally like a dish. Common in Primulaceae and Oleaceae plants such as Primula and Winter jasmine.

Funnel-shaped: the lower part of the corolla is combined into a tube, and gradually expands upward into a funnel. Common in convolvulaceae plants, such as morning glory, bowl flower and so on.

Bell-shaped corolla: Corolla gathers into a wide and slightly short tube shape, and the upper lobe expands into a bell shape. Common in plants of Campanulaceae and Draconidae, such as Platycodon grandiflorum, Adenophora adenophora, Gentiana scabra, etc.

Radial corolla or rotating corolla: The lower half of the corolla is combined to form a short tube, and the lobes extend from the base to the periphery like spokes. Common in solanaceae plants such as tomatoes, potatoes, peppers, eggplant, medlar and so on.

Tubular corolla: Most corollas are combined into a tubular or cylindrical shape. Discoid flowers (flowers near the center of the inflorescence) found in the flower heads of compositae plants such as sunflower and chrysanthemum.

Tongue: the base of corolla is fused into a short tube, and the upper part is fused and spreads to one side, like a flat tongue. Found in compositae plants, such as dandelion, > >

Question 4: The classification of corolla is based on the classification of plant corolla. Classification is mainly based on the number, shape and clutch state of petals, the length of corolla tube and the shape of corolla lobes. The shape, size, number and combination of petals that make up a corolla vary with different plant species and are often used as an important basis for plant classification. Common corolla types are lip-shaped corolla (such as sage), rose-shaped corolla (such as rose), cross-shaped corolla (such as cabbage), funnel-shaped corolla (such as morning glory) and bell-shaped corolla (such as platycodon grandiflorum). Some plants have appendages on the corolla or between the corolla and stamens, such as the yellow cup in the narcissus and the flaky protrusion on the claw top in Quirrell's corolla, all of which are corollas. Corona mostly has bright color and fragrance to adapt to insect pollination.

Chrysanthemums from China were introduced to Europe in the late Ming and early Qing Dynasties. People in China like chrysanthemums very much. Since the Song Dynasty, there has been an annual Chrysanthemum Festival among the people. In ancient myths and legends, chrysanthemum was endowed with the meaning of good luck and longevity. Poets and painters of past dynasties in China wrote poems and painted many pictures with chrysanthemums as the theme. Therefore, a large number of literary and artistic works and chrysanthemum appreciation experiences in the past dynasties have left many excellent works for people, which will last forever.

Chrysanthemum morifolium-morphological characteristics

Chrysanthemum, a cultivated species of chrysanthemum in Compositae, is a valuable ornamental flower cultivated by long-term artificial selection, also known as art chrysanthemum, also known as treasure chrysanthemum. There are more than 1000 varieties. Perennial herbs. The plant height is 20-20-200cm, generally 30-90 m, the stem color is light green or brown, most of them are erect branches except the cliff chrysanthemum, and the base is semi-lignified. Simple leaves alternate, oval to oblong, with serrated edges. The head is terminal or axillary, and one or several flowers are clustered. The ligulate flower is female, and the tubular flower is bisexual. Tongue-shaped flowers are divided into four categories: bottom, spoon tube and abnormity. They are rich in colors, including red, yellow, white, ink, purple, green, orange, pink, brown, snow blue and light green. Tubular flowers have developed into "laurel petals" with various colors, such as red, yellow, white, purple, green, pink, multicolor and intermediate colors.

Inflorescences vary in size and shape, with single and double petals; There are flat and spherical; There are long flocs, short flocs, flat flocs and rolled flocs; There are hollow and solid ones; There are straight, drooping, diverse styles and complex varieties. According to the flowering period, there are early chrysanthemum (blooming in September), autumn chrysanthemum (10 to 1 month) and late chrysanthemum (12 to1month), but after the gardener's hard cultivation and the change of sunshine conditions, there are also May flowers. According to the flower diameter, those with flower diameter 10 cm or more are called chrysanthemums, those with flower diameter 10-6 cm or less are called zhongju, and those with flower diameter less than 6 cm are called Xiao Ju. According to the type of valve, it can be divided into three types: flat valve, pipe valve and spoon valve.

Chrysanthemum plays an important role in the world cut flower production. Cut flowers should have neat patterns, flower diameter of 7- 12 cm, bright colors, no pests and diseases, dark green leaves, straight stems, height above 80cm and long water retention period. Cut chrysanthemum can be planted underground, with the plant spacing of 12- 13 cm and the row spacing of about 15cm. There are 50 plants per square meter, which need to be supported by nets to keep the plants upright.

Chrysanthemum can promote and inhibit cultivation. In the season with long sunshine time, from 17 to 9: 00 the next morning, the daily sunshine time is 10 hour. When the bud becomes colored, it will stop shading and bloom early. In the season of short sunshine, the daily dosage is less than 14 hour, which can control the flower bud differentiation and delay the flower supply time.

Rose: Rose mainly includes small rose, moon red, discolored rose, cut rose, edible rose, vine rose, big rose, rich rose, miniature rose, tree rose and ground cover rose.

① Small rose: The plant is short and multi-branched, the height is generally less than 25cm, the leaves are small and narrow, and the flowers are also small, with a diameter of about 3cm, which is rose red, double or single. Suitable for potted bonsai materials, there are not many cultivated varieties, but small roses play a major role in dwarfing high species.

② Rose Red: The stems are slender, often purplish red, the leaves are spiny or nearly spineless, with purple halo, the flowers are solitary, purple or dark pink, the pedicels are slender and drooping, and the varieties are iron petal red and red rose. ③ Color-changing rose: a single flower, which is light yellow at first, then orange red and red, and finally slightly dark.

Cut roses

This kind of rose has long branches, upright and straight, high cup-shaped buds, beautiful patterns and many colors. In this base, the stem cuttings and fruit seedlings of Japanese thorn-free rose are used as rootstocks to graft into seedlings, and the root system is particularly developed (reticulate) and has strong stress resistance. The annual output can reach 150-200 branches/square, which is an ideal seedling for fresh cut flower production.
