For continuation of future generations, increase the variety and quantity. Flower breeding many ways summed up in two categories. This is sexual reproduction and asexual reproduction.
Sexual reproduction sexual reproduction is the seed propagation, as seeds by the female flowers, stamens are formed by mating sexual organs. Flower planting method is one of the most common breeding methods. Seed sowing, seedling growth and development of robust, long life, especially in cultivating new varieties of flowers and more using this method. Inadequate and difficult to maintain the inherent characteristics of the mother trees. Seed sowing in the following measures:
direct seeding herbaceous flowers in general, such as zinnia, aster, marigold, impatiens,cheap UGG boots, Begonia, Calceolaria cineraria, which does not carry out any treatment that can be directly sown seedlings.
warm water soaking peony, sorbifolia hard shell seeds, etc., can be soaked in warm water 60 ℃ 24 hours after the row planting.
ash seed dressing where there is oil in the seed coat the seeds of wax, such as magnolia, torch trees, ash and water can mix synthetic seed paste, wax off after sowing, the germination rate.
contusion species Pihe flower, canna and other flowers, use the rasp to the seed before sowing the seed coat both ends of broken file, then use warm water for 24 hours can promote the rapid germination of seeds.
cracking method flowering plum, Prunus davidiana, apricot in the winter before the open field planting, irrigated soil freezing in winter, the species of shell is cracking, the following spring to take root.
Sand osmanthus, praecox, rose type of seed, early winter on the pot with wet sand marinated, placed 0.5 m deep in the ditch, covered with straw, out next spring, for planting seedlings , will soon sprout. Flower seeds are generally sown after the casing, the thickness of the seed volume of not more than 2 to 3 times, but the small seeds,UGG boots clearanc, such as primrose, flowers such as Begonia, generally do not cover soil after sowing,UGG boots cheap, the seedling pots to cover the glass.
asexual reproduction asexual reproduction known as vegetative propagation, it is the use of flowers, roots, stems, leaves and other vegetative organs of the breeding method.
cutting method, cutting method is also known as scissor flower stems, leaves or roots for cuttings, insert the hotbed of sand, or dipped in water, to promote its new hair roots as an independent new plants. Which sticks inserted, is the most commonly used flower breeding methods, such as rose, jasmine, hibiscus, hibiscus, Milan, rubber tree, laurel, crape myrtle and so on. In addition, leaf cutting and root cuttings. Flowers with hairy leaf cutting Yehai Tang, tiger Piran, Sinningia, African Violet, etc.; with root cuttings of flowers and plants are perennial phlox, early round bamboo, peony and so on.
layering is to press flowers, branches and other buried objects or wrapped up with dirt, roots cut away from the mother after the formation of new plant breeding methods, including music sticks layering and layering the high branches. Select top 1 to 2 years old branches, the loop peeling, wrapped with plastic film, or peat moss into the girdling at the soil, water once a week into the bag, rooting from the mother after the cut, further planting. Qu appropriate layering branches have spring flowers, Jasmine, Verbena, climbing walls tiger, Peak, etc.; suitable for high-pressure section of the flower branches are in Milan, white orchids, chinensis, citrus plants.
tiller ramets method to flower buds, corms, bulbs, roots, stolons, etc. separated from the mother tree down on a separate plant, making the new plant breeding methods, such as lilac, pearl plum, even Alice,UGG shoes, yellow flowers such as suitable Rosa tiller bud; planting gladiolus bulbs suitable points; tulip, hyacinth, lily bulb planting suitable points; dahlia tuber plants suitable points; tuberose tubers suitable for planting points; Chlorophytum Duchesnea indica plants suitable for sub- stoloniferous or give birth to the buds of branches.
grafting method is to plant a specific branch or bud (commonly known as such as Prunus davidiana for stock, can be grafted on plum, Prunus triloba and Bi-tao. Grafting can be divided into Zhijie (before and after the vernal equinox can be grafted on plum, before and after the beginning of autumn as rootstock with yellow chrysanthemum chrysanthemum); budding (Limit of Heat before and after budding, such as rose, Long Zhaohuai, grapes and various fruit trees, can this method) ; by then (the two different species of plants connected together by the contact surface of the cortex to a knife cut off, exposing the xylem, and then tightly with plastic Shengzha, incision healing, top of the rootstock and scion of the lower branches cut branches out, making the new plant; flush, also known as their counterparts in access (usually used for grafting cactus succulent flowers).
tissue culture and rapid propagation of this method also belongs to asexual reproduction, is the choice of some vegetative organs of flowers such as shoot tip, leaves or flowers, artificial medium in a sterile culture, its growth and development, with less material in the short term the large population of flower seedlings. Most herb flowers, such as African violet, Sinningia, horseshoe Lin, flamingo, mosaic lines, Hemerocallis, phlox, hosta and other tissue culture can be applied. Many woody flower tissue culture can also be used, but more difficult than the grass flowers.
