Camellia breeding method

Camellia has many breeding methods. Sexual reproduction and vegetative propagation can be used. Among them, cuttings and abutments are the most common.

1. Cutting method This method is the most convenient, the cutting time is best in September, and it can be in spring. Select well-growth, semi-lignified shoots, remove the base leaves, retain the top 3 leaves, cut with a knife into a bevel. Immerse in 200 ppm to 500 ppm of indole butyric acid for 5 to 15 minutes, dry it, and insert it into a basin or vermiculite basin. After watering, the wounds healed in 40 days and rooted in about 60 days. The use of vermiculite as a plug-in bed, the root faster than the sand bed.

2. By selecting the appropriate species such as oil tea as the rootstock, the valuable camellia can be obtained. The connection time is usually between the Ching Ming Festival and the Mid-Autumn Festival. First, plant the rootstock in a pot, and use a knife to cut away about half of the area you want to join. The incision should be smooth. Then the two sides are closely attached to each other and wrapped with plastic film. Watering the rootstock twice a day can heal it after 60 days. At this time, it can be planted in the shade, avoiding direct sunlight. In February of the following year, the tail of the rootstock was trimmed with a knife and the plant was replanted.

3. Leaf cuttings Camellia propagation generally uses cuttings for cutting propagation, but some rare varieties are also restricted by the source of shoots, or they may affect the tree shape after they are picked. Therefore, leaf cutting methods are also used. To use cuttings as the matrix for the mountain mud, 1/3 of the sand can be mixed in to facilitate drainage and drainage. The substrate is contained in the pots and then potted. The leaf plugs are best carried out in the rainy season. The annual leaves are used as leaf plug materials. It is not easy for the old people to take root. Insert about 2 cm into the soil, press the soil tightly after plugging in, pour enough water, and place it in a cool, well-ventilated place. Generally it can be rooted in 3 months, and it can be sprouted in the spring of the second year.
