What self-fertile grades of cherry for cultivation in the Northwest region exist

Often many gardeners complain that cherry perfectly blossoms, and here from it not to wait for some berries or harvest very poor. One of basic reasons to it is that the most part of grades is self-fruitless, that is the cherries pollinators blossoming during the same period are necessary for them for pollination. Selectors work not one decade on this problem and they have created self-fertile grades of culture which can yield harvest without cross-pollination by other versions.

As cherry is pollinated what is samoplodnost and what representatives of culture do not need pollinators

Let's remember botany lessons. Pollination is process of penetration of the created pollen on flower pestle snout. Then pollen sprouts in its column and gets to ovary, impregnating thereby semyapochka.Pollination of cherry flowers is usually made by the flying insects, for example, bees or pollen is transferred by wind. As a result of this process there are ovaries which will become cherry fruits subsequently. The majority of grades of culture are self-fruitless, alone they do not tie fruits, it it is necessary to have for fertilization on the site of several cherries of other versions (so-called grades pollinators) which would pollinate each other.

Not at all cherries sufficient vzaimoopylyaemost. Often happens so that even in the presence of several trees on the site of ovaries on cherry is practically not present. The thing is that not all grades are compatible. It is possible to pick up suitable trees only carefully having studied their characteristics, in particular, time of their blossoming, the introduction period in fructification and also terms of maturing of berries.

Often happens so that on the site there is no opportunity to plant several trees. For this purpose the scientists-landowners have created the whole series of the self-fertile grades having the unusual structure of flower. They have identical size of pestle and stamen with boot. Process of pollination happens because of this feature in bud, even before its disclosure. Other nuance of self-fertile versions is, the fact that their pollen keeps the ability to sprout within two weeks, thanks to it the quantity of ovaries increases several times.

Today selectors have created several dozen self-fertile grades for cultivation in different climatic zones. Cherry — culture thermophilic, but it is quite possible to grow up and receive it remarkable harvest of excellent fruits even in regions with adverse weather conditions. For example, the climate in the Leningrad Region differs in rather soft winters, at this time average temperature is −8...−11 C and often there are both thaw, and hard frosts. And here summer quite cool with temperature of +16...+18 of C. Taking into account all these factors, selectors have created several zoned self-fertile grades of cherry.

Lyubskaya cherry

There are several old checked grades perfectly suitable for cultivation in gardens of the Leningrad Region. One of such is Lyubskaya cherry which has been included in the State registry of selection achievements in 1947. The tree grows to 2.5 meters in height and possesses rare, but sprawling krone with drooping branches on which the most part of fruits is formed.

Berries of rounded shape quite large, their weight averages 4–5 grams. Mature berries are painted in dark burgundy tone. Pulp — juicy and gentle — has sweet-sour taste.

Except samoplodnost, Lyubskaya cherry has also other advantages. She early enough enters fructification, in 2-3 years after landing of sapling it is possible to receive the first berries. The productivity of adult copies is 10–12 kg. Among shortcomings it is possible to note low resistance to defeat by fungal diseases and low winter hardiness.

Lot cherry

One more zoned grade which is grown up not by one generation of gardeners. It has been included in the State registry of selection achievements in the 40th of the last century and recommended for cultivation in the Northwest region including the Leningrad Region. Lot yields average crop of juicy fruits which mass is 4-4.8 g. Form of berries bochonkovidny, and taste sourish and sweet with small slightly bitter taste.

Among undoubted advantages of cherry Lot it is possible to note it:

  • samoplodnost;
  • regular productivity;
  • resistance to defeat by fungal diseases and fruit gnilyam.

Amorel cherry grade pink

At this kind of cherry stable and excellent productivity, it presents the owners with tasty sourish and sweet berries even at rainy summer. At the same time the grade has very early term of maturing.

Cherries have the ploskookrugly form and average weight (about 4 g). The thin skin is painted in gentle-pink shade, pulp has lighter tone, and juice — colourless.
