Coronation is not chrysanthemum brain, there is a difference between the two. The main difference is that the subject classification is different, different morphological characteristics, different habits, as follows:
A, subject classification is different
1, Chrysanthemum
Orchidaceae, Asteraceae, Tubular Flower subfamily, spring chrysanthemums, Chrysanthemum genus plants.
2, chrysanthemum brain
Genera Ornithoptera, Asteraceae, tubular flowers, chrysanthemum subfamily, chrysanthemum plants.
Two, different morphological characteristics
1, Chrysanthemum
Stem smooth and glabrous or a few smooth and glabrous, up to 70 cm high, unbranched or branched from the middle and upper parts. Middle and lower stem leaves long elliptic or long elliptic obovate, 8-10 centimeters long, sessile, two pinnately divided. One is parted or divided, with 4-10 pairs of lateral lobes. The second division is lobed, cleft or y lobed, the lobes ovate or linear. Upper leaves small.
2. Chrysanthemum Brain
The stalks are slender, erect or semi-prostrate growing, glabrous or with fine hairs near the upper part, the plant is 30-100 centimeters tall and extremely branched. Leaves are simple and alternate, ovoid or long elliptic, 2-6 cm long. The leaf margin is coarsely compound serrate or bipinnately parted, and the leaf base is slightly contracted into a petiole with narrow wings.
Three, different habits
1, Chrysanthemum
Chrysanthemum belongs to the half-hardy vegetables, light requirements are not strict, generally to the weaker light is good. Its short sunshine vegetables, in the cool and mild, soil relative humidity is maintained at 70% of an 80% environment, is conducive to its growth. In the long sunshine conditions, nutrient growth can not be fully developed, and soon into the reproductive growth and flowering and seed.
2, chrysanthemum brain
Chrysanthemum brain cold and heat resistance, underground roots can safely overwinter, barren and drought, avoid flooding, strong light is conducive to the growth of its stems and leaves, short sunlight is conducive to the formation of its flower buds and shoots flowering. Chrysanthemum cabbage seeds can germinate at 4 ℃ or more, seedling growth temperature of 15 ~ 20 ℃, at 20 ℃ when the growth of the young stem and leaves of the best quality, the adult plant in the hot season can also grow. Strong light, long sunlight is conducive to the growth of stems and leaves, in low light plant growth is slow, short sunlight is conducive to the formation of flower buds and flowering.
