Pollinator for Ginkgo Biloba
For understanding the complex procedure of pollination;
it is very important to first understand the structure of
the sperms, ovum and the embryo. Ginkgo
Biloba trees grow dioeciously hence making male and
females grow separately.
The female tree produces ovules in pairs on stalks. Ginkgo
are open (naked) as it is classified
as a gymnosperm.
The Ginkgo Biloba seed has silvery coating. The Ginkgo
Biloba seed's fleshy seed-coat has a disagreeable odor similar
to that of a rancid butter when it decays and fall to the
Each ovule contain an egg cell which appear very green at
the onset but eventually changes its color from greenish-yellow
to finally orange and brown. These ovules can take up to
20-35 years to appear. They appear in spring because the
sunny position makes them more reliable.
The sperms appear in forms of cones. These pollen cones
are more or less similar to catkin which contains the sperms
of the male tree also grow on spring after 20-35 years.
The sperm are large almost about 250-300 micro meters.
The sperms have complex multi-layered structure, which is
a continuous belt of basal bodies that form the base of
several thousand flagella which actually have a cilia-like
motion. The flagella/cilia apparatus pulls the body of the
is made possible by the wind. The actual fertilization of
Ginkgo Biloba seed occurs on the tree. Being male and female
on the separate plants it is very necessary for them to
be in near vicinity for a successful fertilization. There
are very rare chances of pollination by means of insects
When the fertilization is done; which happens to be on
the tree, the embryo falls off and is taken to a distinct
place wherever the wind takes it, and is planted over there.
Though the natural cycle is very demanding as it takes at
least 25 to 30 years for the male and female plant to get
mature and start producing gametophytes.
Though once it has its roots in the earth it is very unlikely
for it to die a natural death. But once the plant is grown,
it is very easy to maintain it. It is not a demanding plant.
Resistant to extreme temperatures makes it survive in snow
as well as in heat where the metal could melt. Its strong
roots and strong stem helps him to stand tall in the winds
If it can survive after an atom bomb attack in Hiroshima
than it can survive any where!!! Its stem has some significant
components and properties
that make it resistant to plant diseases and insects to
Ginkgo Biloba is widely cultivated these days in China,
Japan, Korea, Germany and United States of America. Many
other European countries are taking wide interest in this
Ginkgo Biloba tree
and are advancing the methods for its easy cultivation and
are planning to make Ginkgo gardens; so that humans can
take maximum benefits out of this tree.
