Variegated violets.
1946. USA. An exhibition of violets. Tens grades of the African violets, various shades of colours on green foliage … But one copy involves(attracts) general attention - colouring of his(its) foliage motley!!!
Then it was by sensation, and now variegated by violets nobody will surprise. They are practically in all collections of the collectors of violets and continue to win hearts of the fans. The high decorative effect the year round, irrespective of the period of flowering, large, various colouring flowers, in harmony with foliage, minimal leaving(care) is a worthy alternative to simple grades with green foliage.
All grades with motley foliage are similar to the first sight - stain and hyphen of white, cream, pink or yellow colour on a green background. But it not so. Three large groups of variants of motley foliage at the African violets now are known.

1.Top variegated .

For the first time this kind was received Etel the Champion in 1953 in USA is there was a grade "Frosty". Sometimes this kind name "champion". At grades of this kind most brightly younger foliage almost wholly deprived chlorofill also is effectively painted. In process of growth the foliage becomes green and the colour colouring is distributed on edges.
This type became an ancestor of the majority modern most beautiful variegated of grades.

2. Mosaic variegated .

The Dutchs Anne and Frank Tinary are the authors mosaic пестролистности - as homogeneous shading on all sheet plate of a plant, irrespective of age of a sheet. This kind meets very seldom.

3.Bordering variegated .

Б Was received in 1959 in USA That Lou and is named as her name. The bordering on foliage can be thin, hardly appreciable, or wide, but always only on edge(territory) of foliage - both young and old, leaving middle green.
The colour colouring of foliage depends on a type of a pigment which is taking place in crates. Chlorofill defines green colouring, carotin- yellow, xantofil- red, and antocian - pink and violet. The white sites contain crates in general deprived painting pigments. These features are necessary for taking into account at cultivation of violets with colour foliage.

ILLUMINATION

The crates of foliage deprived of a green pigment - chlorofill, do not participate during photosynthesis, and on the limited green parts of a sheet all loading of a feed(meal) of a plant is necessary. Hence, the plant will test " light famine " there, where the simple grade at the most insignificant lack of light will be normal to develop. Therefore plants with motley foliage are necessary for placing on a light place, it is better under luminescent lamps ensuring sufficient illumination within 12 hours. The excessive illumination too is undesirable, since results in reduction variegated, but such contents allows faster to receive green weight of the socket necessary for flowering.

FERTILIZERS

For reception of intensive green colouring of foliage at usual violets the nitric fertilizers necessary for job chlorofill are used. At cultivation of motley violets the basic task - to reduce quantity(amount) of green crates to liberate a place for other pigments. Hence, it is necessary to reduce nitrogen in nutritious fertilizers mixes. It is best to alternate(interleave) complete fertilizers and fertilizers to the reduced contents of nitrogen. The summer recommends to fertilize such violets only by fertilizers with the low contents of nitrogen.

TEMPERATURE

At ground always there are nitric bacteria, which at high temperature of a ground begin is amplified(strengthened) to be made multiple copies and by that increase quantity(amount) of nitrogen. Therefore for reception of the best copies variegated violets it is necessary simultaneously and cool contents (from 16 up to 21 degrees) and reduction of nitric fertilizers. At higher temperature the growth of the socket is slowed down, листья become shallow and are deformed, the quantity(amount) of variability sharply decreases. An optimum arrangement of violets with motley foliage - on the lowermost shelfs of racks or even on a floor, where is cool, and besides only at a sight from above it is possible to consider them in all beauty.

DUPLICATION

For rooting it is necessary to take the most green sheet - in him most of all of nutritious substances for growth of young plants. In rest corrected same, that for usual grades. The first appeared foliage at grades with motley листьями, as a rule, completely are deprived of green crates and eat at the expense of a parent sheet. Therefore to separate young plants it is possible only then, when they will type(collect) enough of green weight - after occurrence of 4-5 pairs foliage. At this time colourless sites of foliage can be gone, but then will gradually be shown on young foliage.
