What are the common propagation methods for African violets?
African violets (see details) have a long flowering period; with proper cultivation, they can bloom all year round. There are many artificial propagation methods for African violets, and the survival rate is very high, which is why so many flower lovers adore them. Generally, African violets can be propagated by leaf cuttings, stem cuttings, tissue culture and sowing. Here, the editor introduces these four common propagation methods for African violets; friends who like them can learn along.
African violet
I. Leaf cutting method
African violets are commonly propagated by cuttings, mainly leaf cuttings. After flowering, choose healthy, plump leaves, cut them off leaving a 2 cm long petiole, let them dry slightly, and insert them into a sand bed, maintaining high air humidity, with a room temperature of 18-24°C. Roots form 3 weeks after insertion, seedlings will be produced in 2-3 months, and they are moved into 6 cm pots. During the cutting process, treating with vitamin B is beneficial to the growth of seedlings after African violets root; treating the petioles with 25 mg/L kinetin for 24 hours is favorable for the formation of adventitious buds. It takes 4-6 months from cutting to flowering.
II. Stem cutting method
The stem cutting propagation method is also one that African violets will use, mainly after the flowers fade in spring. Combined with repotting and changing the soil, the underground tubers are divided and planted. Seedlings form quickly, but the plant shape is not attractive enough, and because the plant is not renewed, the growth is not vigorous enough.
III. Tissue culture method
Nowadays, the more popular propagation method for African violets is tissue culture propagation, using leaves, petioles and epidermal tissue as explants. Use MS medium plus 1 mg/L 6-benzylaminopurine and 1 mg/L naphthaleneacetic acid. Adventitious buds grow 4 weeks after inoculation, and rooted plantlets can be planted 3 months later. The plantlets are transplanted into a substrate of half leaf mold and half peat moss soil, with a 100% survival rate. At present, the United States, the Netherlands, Israel and other countries all have test-tube plantlet production of African violets. However, this method produces relatively many plantlets and is not very suitable for home cultivation.
IV. Sowing method
Sowing propagation of African violets can be done in spring and autumn. For greenhouse cultivation, autumn sowing in September-October is preferable, with a high germination rate, and the seedlings grow robustly, flowering in the following spring with large plants and many flowers. Sown in February, they flower in August, but the growth vigor is somewhat poorer and there are fewer flowers. African violet seeds are tiny, so the sowing soil in the pot should be fine; after sowing, do not cover with soil, just press flat. The suitable germination temperature is 18-24°C; they germinate 15-20 days after sowing, and the seedlings are moved in 2-3 months. During the seedling stage, note that the potting soil should not be too wet. Generally, it takes 6-8 months from sowing to flowering.
An introduction to the propagation methods of African violets
African violets are a kind of flowering plant we like very much, and they are also a flower relatively often used to decorate and beautify the environment. The plants are small and compact, the flower colors are bright and lovely, the decorative effect is good, and cultivation is relatively simple. Let us take a look below at the propagation methods of African violets!
