What are the methods of propagation of common flowers?

Camellia

Budding camellia in the green leaves under the backdrop of the sunshine is particularly shy and beautiful, spring is the season of camellia blooming, is a great time for human beings to enjoy the flowers, but also a good time to reproduce camellia, so what are the methods of reproduction of camellia?

A, cuttings propagation

In mid-June and around the end of August is most suitable. Select the crown of the external organization is full, complete leaf, leaf buds full of semi-mature branches of the current year for the plug, the length of 8 to 10 cm, the apex to stay 2 leaves. Cut, the base as far as possible with a little bit of old branches, easy to form healing tissue after insertion, fast rooting. Cutting early in the morning, to cut with the insertion, inserted into the substrate about 3 cm, cuttings require the leaves to intersect each other, inserted with a finger to press the real. Shallow insertion is good, so breathable, healing and rooting fast. Plug beds need shade, daily spray foliage, keep moist, the temperature is maintained at 20 ~ 25 ℃, about 3 weeks after insertion began to heal, 6 weeks after rooting. When the root length of 3 to 4 centimeters when transplanted into a pot. Cuttings using 0.4% to 0.5% indole butyric acid solution dipped in the base of the plug for 2 to 5 seconds, there is a significant promotion of the effect of rooting.

Second, grafting propagation

Commonly used in cuttings rooting difficulties or propagation material less varieties. In May to June, the new tips have been half-quality grafting survival rate is the highest, catching live sprouting fast. Rootstock to oil tea-based, October seed, winter sand, the next year in early April sowing, to be seedlings grow to 4 ~ 5 cm, can be used for grafting. Using the shoot splitting method, with a razor blade to cut the germ part of the bud anvil, in the center of the embryonic axis cross-section, along the medulla upward longitudinal cleave, and then take a section of the camellia scion, but also the section of the lower part of the base cut into a positive wedge, and immediately inserted the peeled scion into the bottom of the rootstock cleavage, aligned with the two sides of the formation of the layer, tied with a cotton thread, set on a clean plastic pockets. Remove the pocket after about 40 days, and it will take about 60 days to bud and twig.

Three, high branch pressure propagation

High branch pressure more in April to May during the method is to choose the previous year's branches, in the high-pressure parts of the ring peeling, ring peeling width of 0.5 centimeters; with the moderate size of the plastic film wrapped in the ring peeling parts, wrapped in the length of 10 to 15 centimeters, the first will be the lower mouth tied tightly, the inside of the moist culture of the soil, often to keep the soil moist, and then tied tightly on the plastic wrap. Soil moist, and then tighten the upper mouth; rooting can be cut and planted separately.

Camellia

Four, seed propagation

Suitable for single-valved or semi-valved varieties. Seeds mature in mid-October, can be sown. To shallow sowing is good, with vermiculite as substrate, covered with 6 mm, room temperature 21 ℃, 10 hours of light every night, can promote seed germination, 15 days after sowing began to sprout, 30 days within the seedling height of 8 centimeters, the seedling with 2 ~ 3 leaves when transplanted.

Five, group culture propagation

Explants commonly used live seedlings, after routine disinfection, cut into 1 cm long inoculated in the addition of agonist 1 mg / liter, 6-benzylaminopurine 1 mg / liter and indole acetic acid 0.1 mg / liter MS medium, after 4 weeks of culture only the formation of healing tissue, and not the formation of buds. and no buds were formed. After transferring to a new medium, a single 4-cm branch began to form, which was then soaked in indolebutyric acid 0.5 mg/l for 20 min and then transferred to 1/2 MS medium, where it grew roots after 4 weeks. Seedlings were transplanted into pots containing perlite and peat after 8 weeks of growth on long root medium.

The above are the five methods of propagation of camellia, in general it is still relatively easy to propagate, as long as the operation method is right, good management of the medium as well as the control of the environmental temperature, then the camellia can certainly be propagated successfully.
