you are: Features of pollination of various cultures

The wild strawberry of the majority of grades has oboepolye tsvetki which can be pollinated within a grade. But there are grades (for example, the Member of the Komsomol) at which stamens are underdeveloped also pollination by probably pollen of other grade, therefore on plantations of such grades it is necessary to land plants of a grade-opylitelja with well developed man's generativnymi bodies for pollination of the basic grade. For a grade the Member of the Komsomol good opyliteli grades Roshchinsky and Mysovka.

For pollination of wild strawberry of 1 hectares 1-1,5 beer families are required.

Citrus. Tangerines and oranges give to bees plentiful gathering of nectar and flower pollen, insects willingly visit them. Cross-pollination tsvetkov bees considerably raises crops of citrus and improves their quality. On 1 hectares of citron plantings it is necessary to bring up 2-3 families.

Grapes. Among grapes cultivars plants with oboepolymi tsvetkami prevail, many of which concern grades self-pollinated. At some grades (Korna the Negro, etc.) without carrying over of pollen of other grades small seedless berries can develop only. Wild-growing grapes - dvudomnyj, its pollen are transferred not only a wind, but also insects. The wind as opylitel is inefficient. Its force sharply decreases among plantations, especially when a wind direction perpendicularly to grapes numbers.

Pollen Carrying over tsvetkov grapes insects raises a crop of berries and their quality. TSvetki involve melliferous bees with a pollen abundance, aroma and nectar. Bees from grapes collect basically pollen.

For pollination of grapes of grade SHasla of 1 hectares white one beer family is required. Beehives place so that bees flied lengthways rjadkov and from below upwards. Flight activity strengthen selection flower pollen from nests at the maintenance in them opened rasploda. At observance of these rules of a bee well visit blossoming grapes. Experiences of scientific institutions establish positive influence of cross-pollination by bees and some grades of grapes at use of reception of training. So, in state farm ' the Blossoming Moldova ' on a site of hybrid grapes Zajbel 14 has been reaped a crop near an apiary 70,1 ts, and on the sites which were not visited by bees, - 50,2 ts about 1 hectares.
