How Dahlia reproduces scientifically

Dahlia has four methods of cutting, ramification, seeding and tissue culture, but it mainly uses ramets, cuttings, and sowing.
1 branch breeding. After the spring, most of the wintering roots were removed and sand culturing was performed at the end of March. When covering, the root neck was exposed and the water was poured. The germination was performed at 18°C. When the buds were centimeters long, the root was divided into several pieces, each Must have a full bud, the cuttings coated with ash, planted in pots or seedbeds. This method is simple, high survival rate, but less.
2 cutting propagation. The same sand pebble, when the shoot length is 10 cm high, can be plucked from the roots, a little rooting powder, cuttings in the seedlings in the mud pot or plain sand or seedbed, sprayed twice a day, rooting and then move Plant a pot. Due to the different quality of the roots, the germination and growth are of different heights. This method has a lot of reproduction and can maintain the characteristics of good varieties.
3 Seed breeding. Dahlia single-flowered varieties can be self-pollinated, and the double-flowered varieties require artificial pollination for seeding. When the seeds are ripe, they are harvested in October, preserved after drying, and sowed in the sulcus basin or seedbed in the following year. The mulching of the mulching seeds is a degree, and the cultivation soil is kept moist. At 20°C, seeds can be grown for 1 week. When germination is unearthed and three true leaves are grown, they can be transplanted on the pots and they can be flowered by the end of September.
