Pollination of fruit and berry cultures. Almost all kinds of fruit and berry cultures - typical entomofilnye plants. For many kinds fruit it is characteristic protoginija: ryltse a pestle ripens earlier pylnikov, that excludes pollination possibility tsvetkov own pollen. The majority of grades of apple-trees, pears, plums, cherries and other fruit crops do not fasten any fruits not only at pollination by pollen of own flower and a tree, but also pollen from other tree of the given grade. Thus, at these plants self-pollination possibility is excluded not only spatial isolation generativnyh flower bodies, but also their physiological incompatibility. Even grades of fruit crops which can form fruits or berries at pollination by pollen of the same grade, give bolshy a crop of fruits and better quality at cross-pollination by pollen from other plants of the same grade.

Distinguish compatible grades (pollen is capable to pollinate the given grade) and incompatible, that is such which pollen does not cause zavjazi fruits in the given grade. For example, for an apple-tree of grade Antonovka opyliteljami grades Borovinka, White having poured (they are compatible) are considered as the best. At a garden bookmark necessarily land near to trees of the basic grade grade-opylitelja trees. For the best cross-pollination of the basic grade it is necessary, that the grade-opylitel blossomed annually and simultaneously with the core. The Grade-opylitel should be well adapted for a local environment and differ good productivity.

Usually through each 4-5 numbers of the basic grade put one number of a grade-opylitelja. To increase number of numbers of the basic grade does not follow, as at bolshej remoteness from trees-opylitelej crops decrease. Practice has shown, that the highest crops of fruits turn out in the numbers adjoining to numbers of trees-opylitelej as optimum conditions for cross-pollination here are created.
