The cherry is presented by many self-sterile grades. Some of them cannot be pollinated by own pollen as ryltse leaves a bud before maturing man's generativnyh bodies. In tsvetkah some grades (the Duchess pear, Excellent) is not formed at all pollen. Many grades are incompatible, careful selection of grades-opylitelej therefore is required. At cross-pollination productivity and quality of berries of a cherry considerably raises. At free pollination tsvetkov cherries zavjazyvaemost fruits makes 11,1%. And at isolation tsvetkov - 0,33%, the average percent of infructescence at pcheloopylenii has made 15%.

In flowering and pollination biology the sweet cherry which productivity also depends on its pollination tsvetkov bees is close to a cherry.

Malines - one of the most widespread berry plants of our country. mnogopestichnyj and mnogotychinochnyj the raspberry flower is capable to be pollinated and own pollen, but is better pollination there are with the assistance of insects as sticky heavy pollen is not transferred by a wind, and columns in tsvetkah is much longer than stamens. In a difficult fruit of a raspberry everyone separate plodik can develop only as a result of fertilisation isolated zavjazi. At a lack of insects-opylitelej the part zavjazej a flower therefore turn out small, underdeveloped, the wrong form poor quality fruits is impregnated only.

The Currant black and red can be pollinated by own pollen, but insects among whom the leading part is played by melliferous bees usually participate in this process. At isolation from insects only the small amount tsvetkov forms zavjazi. At pollination by bees the crop raises on 18-44%.

The Gooseberry has tsvetki, adapted for cross-pollination as pylniki ripen earlier, than ryltse a pestle. Sticky and its rather heavy pollen is not transferred by a wind. Zavjazyvaemost fruits at isolation from insects can fluctuate from 9 to 35,6%.
