When determining the varietal composition of the orchard, one must remember, that only some varieties of fruit trees are self-pollinating. On the other hand, foreign-pollinated varieties predominate, which flowers, to bear fruit, they must be pollinated with pollen of other varieties. Pollen produced by one variety may pollinate the flowers of another variety, if several conditions are met. The first condition is that a variety that produces pollen is produced, that is, by the pollinator, viable and well-germinated pollen. All triploid varieties are bad pollinators, because their pollen shows a very low degree of viability. The second condition is the simultaneous flowering of the pollinator and the pollinated variety. The close proximity of trees of both varieties is also necessary for this, that there could be mutual pollination. To avoid complications, resulting from the introduction of too many variations for one accommodation unit, you should strive, if it is possible, that both cultivars would be mutually good pollinators. When selecting pollinators, it is worth considering other properties of these varieties. It is advisable, that they have a similar time of maturation, similar tree growth force and a similar degree of susceptibility to diseases. Careful selection makes it easier to care for trees and harvest fruit.
