Nectar or
flower essence is a sweet liquid rich in sugar produced by flowers from plants
in bloom to attract the arrival of pollinating animals like insects. Nectar is
produced by the nectar gland which usually lies at the base of flower jewelry
(perianthium), so pollinating animals will inevitably intersect with the
anthera and pistil when taking nectar.
Nectar is a food source for
bees. In agricultural cultivation, nectar is very important to attract the
attention of pollinating insects.
The scent of flowers and the
color of the crown leaves is a signal for the insects of the availability of
nectar. The crown leaf that looks single-colored according to the vision of the
human eye, actually has lines centered to the bottom of the flower when
photographed with a film sensitive to ultraviolet light.
The lines centered on the
base of the flower can be seen by insects and are a gesture of the location of
the nectar. Different types of plants also produce nectar that attract other
pollinating animals such as bats and birds. In contrast, flowers from plants
that do not require pollinating animals (abiotic pollination) do not produce
nectar.
Nectar consists of two
types, floral nectar and extra floral nectar. The floral nectar is produced by
the nectar gland, while the extra floral nectar is produced by the plant other
than flowers. Extra floral nectar is intended to attract the attention of
insects like ants that suck nectar as well as prey on plant destructive
insects.
