POLLINATION BY INSECT IN THE SALVIA PLANT..

Pollination is the transfer of pollen grains from anther to stigma of a flower

▫▪Pollinating agents include wind, insects, birds etc.

Honeybees have a number of the common characteristics of a good pollinator.

▫They are completely dependent on flowers for food and they frequent only the parts of plants that bear pollen or nectar.

▪They are clothed in feathery hairs that retain pollen.

▫They are not injurious to plants and do not pose a public nuisance.

▪Because they are so diligent in providing and storing nectar and pollen for their offspring, they are more reliable flower visitors than insects that only have to feed them.

▪The sugar concentration and volume of nectar are important attractants.

▫These attributes vary among flower species and variety. Sugar concentrations range from 5-80 percent, but those below 40 percent are less attractive to honeybees.

▫When pollen is very abundant in a flower species honeybees will be more attracted.

▪They may also prefer different kinds of pollen. The bees quickly learn when certain flowers will dehisce their pollen.

▪The preferred range of pollen collectors is usually shorter than that of nectar collectors. For commercial honey production beekeepers usually do not expect the flower source to exceed two miles from the hive.

▫▪ With pollination the closer the flower source the more bees will locate it and the more visits can be made.
