you are: Features of pollination of various cultures

Lucerne possesses one feature connected with pollination: its flower is arranged so, that still it is not enough one visiting by its insect, that there was a pollination. Generativnye flower bodies (the pestle and a stamen) are closed by petals lodochki and are in an intense condition under the locking device. That there was a flower pollination, it is necessary to make some effort, to release ryltse a pestle from a mucous film and to put pollen; all it occurs during that moment when a bee, visiting a flower, starts hobotok in the flower centre between a sail and lodochkoj, and legs rests against nimbus wings. Pulled out of petals lodochka - generativnaja the column strikes in the basis hobotka, and then nestles on a sail. The closed flowering and explosive type of a flower have put a lucerne abreast trudnoopyljaemyh entomofilnyh cultures.

Active opyliteli lucernes - wild single bees. In the course of evolution they anatomicheski also have biologically adapted to lucerne pollination. However difficulty of use wild opylitelej consists that they give in to influence of the person a little, and their number in connection with an intensification of agriculture and application of pesticides is annually reduced. It is established, that in areas ljutsernosejanija security of plants insects-opyliteljami makes about 15 20%.

At plentiful allocation of nectar of a bee willingly visit tsvetki lucernes and often open them, but for more effective pollination of this culture it is recommended to use strong beer families with a considerable quantity opened rasploda (5-6 frameworks) in plank beds both two-case beehives and 10 frameworks in the multicase.
