Beauty gloxinia: propagation by seed and leaf
Gloxinia is a stunningly beautiful plant of the Gesneriaceae family. Large, graceful gramophone flowers, depending on the variety, painted in bright purple, blue, red, pink, white tones rise over wide velvety leaves, gathered in a bunch, on long, luscious peduncles. Florists love gloxinia for festive decoration, a good assortment and a variety of reproduction methods. You can grow a new plant from seeds or vegetative methods: from the stem from a flower, dividing the tuber, from the leaf and even part of the leaf plate. Some gardeners manage to grow an impressive amount of magnificent gloxinia from two leaves.
Clarification: locally grown Gloxinia, this is Sinningia beautiful (Sinningia speciosa), or Hyloxinia hybrid - a species belonging to the genus Synningia (Sinningia) Gesneriaceae family (Gesneriaceae) However, in the same family there is a separate species Gloxinia (Gloxinia), to which our heroine is often referred, which is not entirely true from a botanical point of view.
Gloxinia is very rarely grown by seeds, mainly in breeding work or when propagating varietal specimens. When receiving plants from seeds, it is necessary to take into account the individual requirements for the soil, temperature conditions, relative humidity and lighting.
It is preferable to take the soil for sowing light, based on sand, peat (1 part), perlite and vermiculite (1/2 part). To improve its structure, it is desirable to add finely ground sphagnum moss to the composition. Before sowing, the soil mixture must be disinfected with a weak solution of manganese.
The optimum temperature of seed germination is 20-25 ºС. Under such conditions, the first sprouts will appear within one to two weeks. If the temperature is below optimal, seed germination can drag on for up to a month.
Seedlings are very sensitive to fluctuations in air humidity, so when growing it is better to use a mini-greenhouse, it is easier to create a microclimate that is comfortable for plants.
To sprout seeds faster, they need good lighting. They are sown on the surface of a well-moistened substrate, then placed under diffused sunlight. A good option may be artificial lighting with fluorescent lamps. Watering should be carried out slowly, so as not to wash off the seeds, which gloxinia are very small. For this, drip irrigation or irrigation from a pallet may be suitable.
The grown seedlings need a pick, after it they begin to grow more intensively. Plants dive twice: after the appearance of a pair of real leaves and a month later.
Capacities for planting a young plant are chosen small, 2-3 cm larger than the size of the rosette of leaves. For an adult, a flower pot with a diameter of 9-12 cm is suitable.
Gloxinia from seeds begins to bloom after about 4-5 months. The first buds are recommended to be removed, but for fun, you can leave only one to admire the fabulous flower.
In the first year, the plant can do without a dormant period. Over the winter, it will stretch very much, but with the advent of spring, experienced flower growers recommend pruning, leaving only two leaves. With good sunlight, new shoots will grow quickly, become strong and powerful.
After 9-10 months, the seedlings will turn into adult plants, after which they can be used for propagation by one of their vegetative methods.
Many flower growers treat seeds before sowing in solutions of plant growth and growth stimulants (Epin, Zircon). In this case, it is important not to exceed the concentration of the solution, otherwise you can destroy the seeds. As practice has shown, the optimal solution is 1-2 drops of the drug per 200 ml of water.
Obtaining a new gloxinia from the leaf is the most convenient and promising method of reproduction. Unfortunately, some varieties, for example, ‘Tigrina Pink’, are difficult to propagate in this way; once in the water, the leaf decays very quickly.
Vegetatively, gloxinia is propagated in the month of June and July. Small leaflets take root faster than large leaves, so large leaf blades can be divided into several parts and put them on the root.
Cut off a leaf stalk put in water. When the roots appear, it is planted in a prepared soil mixture. Cover with a glass jar, but so that the edges of the leaf do not touch the walls, otherwise it may rot. It is better, of course, to place the seedling in a mini-greenhouse, it is easier to maintain the optimal humidity and temperature regime in it. It is better to water it in the pan, then there will be more chances that a tuber will appear from the leaf.
The growth of a tuber is signaled by the appearance of young leaves. From this moment it is necessary to regularly air the greenhouse, accustoming gloxinia to independent life. After the growth of the fourth pair of leaves, the plant is taken out of the greenhouse.
It often happens that the leaf does not die out for a very long time, although a large tuber grows. Sometimes the tuber does not grow at all. This suggests that the leaf is fattening. In this case, the sheet plate is truncated by a third, and if it is large, then by half. The slice is treated with crushed activated carbon or drugs with antifungal and bactericidal effects, for example, Fundazole. The cut off part of the sheet does not need to be thrown away, it can be rooted.
Today in the distribution network you can find a special hydrogel - an artificial material of a jelly-like consistency, which contains growth stimulants and bactericidal additives that contribute to the effective rooting of cuttings. Pour the gel into a glass container and lower the sheet into it. After root formation, the seedling is planted in an earthen substrate, in which it further develops.
