Propagation methods of longevity flowers

The propagation methods of longevity flowers mainly include cutting propagation and tissue culture propagation. These two propagation methods have their own advantages and characteristics. In the process of propagation of longevity flowers, different methods can be chosen according to the needs of the actual situation. Let's take a look at the two propagation methods of longevity flowers.

Tissue Culture and Propagation of Longevity Flowers

In the United States and France, stem tips, leaves, stems, flower buds and flowers of longevity flowers were used as explants in the late 1970s, and adventitious buds were induced in MS medium with 2mg / L kinetin and 0.1mg / L naphthylacetic acid. Then rooting was induced by 1/2MS medium plus 1 mg / L indolebutyric acid. The plantlets could grow after 4-6 weeks at room temperature 25-27 ℃ and light for 16 hours.

Cutting Propagation methods of Longevity Flowers

The effect is the best in May ~ June or September ~ October. Select a slightly mature fleshy stem, cut it 5cm long, insert it in a sand bed, cover it with a thin film after watering, take root at 15-20 ℃ at room temperature, take root at 15-18 days after insertion, and pot plant in 30 days. Ten centimeter pots are commonly used. If there are not many seedlings, leaf cuttings can be used. Cut the sturdy and full leaves from the petiole, insert them obliquely or horizontally on the sand bed after the incision is slightly dry, keep the humidity, about 10-15 days, it can take root from the base of the leaf and grow new plants.

Longevity flowers need to pay attention to the following when using cutting propagation methods to propagate:

1. Using net yellow sand, sandy loam or nutrient soil as medium, it is best to disinfect with 0.1% potassium permanganate solution.

2. Pinch 6-10 cm long branches with more than two leaf base segments. When cutting, the cuttings should be cut as high as possible, the lower end of the cut is generally oblique, it is better to be 2mm away from the bottom bud, which is conducive to rooting, and the upper mouth should be flat and more than 4mm away from the top bud. to avoid moisture loss after the upper incision dry and discoloration, resulting in cutting failure.

3. Insert it directly into the medium, and the insertion depth should be 1-2 to 2-3, compacted and watered once. After that, keep the medium moist. Do not water or spray too much, as it will easily cause succulent leaves and stems to rot.

4. if there are conditions after cutting, it can be covered with plastic film to keep warm and wet, which can promote the rapid rooting of branches and ensure the survival rate.

5. Fresh cuttings should avoid strong light, and it is best to avoid fertilization after cuttings under the condition of scattered light.

6. Plug and live, which can take root in a week or so. After new axillary buds and leaves grow, they can be transplanted.
