Abstract

Research has been carried pollen from many plant species, with the aim to find out from
the wall of pollen morphology in the interest pollination carried by insects (entomophyli)
.Material taken from plants belonging to Monoicotyledoneae and Dicotyledoneae. Preparation
was done by acetolysis method and observation using light microscopy.
From the results showed that the pollen in flowers polination carried by insects
(entomophyli) generally have a flat surface, a bit rough with the noise - kind of ornamentation.
Ornamentation in the form of spine or sculpture with a different type for each species.
Key word: Pollen, Entomophyli, ornamentation
Introduction

Flowering is one aspect of plant life. Shape and color of the beautiful flowers, a neat
header regular interest, and the smell of fragrant flowers that invite insects to come looking for
honey .Fruit and seed crops depend on pollination results. Insects can cause pollen move from
one flower to another flower. When the pollen is already carried by the fall on the stigma, it

happens pollination. Once the importance of the role of insects in pollination, it is interesting to
note in particular flower pollen morphological structure, as in; pollen pollination plays an
important role especially in the event of conception.
The beauty of colors, flower shapes, as well as a special smell and produce honey or
nectar to attract different types of insects, so the animals - these animals often visit flowers and
pollinating accidentally (Arnet and Braungart, 1970)
Important role as a pollinator insects and pollen types are shown variations associated with
the visited flower. Some insects are helpful in pollination are bees, flies, wasps, butterflies and
beetles (Bhojwani and Bhatnagar, 1978).

Pollen produced by terrestrial plants is the privilege of development resistance of exterior
walls. The outer wall is eksin that contain wax or some kind of dammar. This helps the wax layer
scattering. Pollination interest carried by insects, the pollen surface ornamentation spine and
there are carved images to assist in the scattering (Kapp, 1969).

Materials and Methods
The samples taken were from the group Monocotyledoneae and Dicotyledoneae, respectively each five species. The group of monocotyledoneae is Lilium longiflorum , Gladiolus sp,
Amaryllis sp, sp Arachnis and Vanda sp, and the group of dicotyledoneae

is Caesalpinia pulcherrima, Crotalaria sp, Sesbania grandiflora Pers, Hibiscus rosasinensis and
Nymphaea sp. Preparation was done by acetolysis method (Soerodikoesoemo, 1983).
Pollen taken from anthers collected in a test tube (vial), which is already filled with glacial acetic
acid, then left for 24 hours. Then transferred into a centrifuge tube, and centrifugation performed.
The liquid was removed and replaced with glacial acetic acid with concentrated sulfuric acid
with the ratio 9: 1. Heating in a water bath from room temperature to boiling. After boiling
heating was stopped and settling for 15 minutes. Subsequently conducted centrifuge, then the
liquid was removed and replaced with distilled water. Observation with light microscope, was
still dark when bleaching is carried out using glacial acetic acid 2 cc of sodium Chlorates 2-3
drops 2-3 , drops of HCl, and then centrifugation. Furthermore, the liquid removed and the
sediments were washed with distilled water 2-3 times, with each laundering conducted centrifuge
again. Last distilled water was replaced with glycerin jelly that has been heated and mixed with
safranin dyes. Further observation with light microscope.
For the identification carried out:
- Mesurement of polar axis, and Equatorial.
- Determining of index P / E
- Determine the type of pollen (by Erdtman, 1952).
- View pollen ornamentation on the walls.
Photoshoot done using Olympus brand camera C 35 A, 100 ASA Kodak film.

In general, pollen of flowers pollination carried by insects (entomophyli) has an uneven surface,
a bit rough, with exquisite ornamentation such as spines, warts and the presence of sculptures sculpture such as nets. Type of individual - each a different species, although included in the
same family, such as Crotalaria sp, Sesbania grandiflora Pers and Caesalpinia pulcherima,
although all three are included in each type of the Leguminosae family is different because each
type of index P / E is different. Likewise with Vanda sp and sp Arachnis which both belong to
4

the family Orchidaceae, also different types . But Gladiolus sp, sp and Lilium longiflorum
Amaryllis sp, all three including the order Liliales (Pudjoarianto and Budi Rahayu, 1977)
have the same type of pollen that is subprolata. Accordingly Index P / E is to determine the type
of pollen from each - each species.

Conclusion
Pollen on flower pollination done by insects (entomophyli) has the structure:
1. Uneven surfaces. Slightly rough surface with ornamentation in the form of spine, the curve ,
warts and sculpture in the form of a net.
2. Type of each type differs depending on the index P / E .
