is a small embryonic plant enclosed in a covering called the seed coat,
usually with some stored food.
is the product of the ripened ovule of gymnosperm and angiosperm plants
which occurs after fertilization and some growth within the mother
formation of the seed completes the process of reproduction in seed
plants (started with the development of flowers and pollination), with
the embryo developed from the zygote and the seed coat from the
integuments of the ovule.
have been an important development in the reproduction and spread of
flowering plants, relative to more primitive plants like mosses, ferns
and liverworts, which do not have seeds and use other means to propagate
propagation involves the union of the pollen (male) with the egg
(female) to produce a seed.
seed is made up of three main parts: the outer seed coat, which protects
the seed; a food reserve (e.g., the endosperm); and the embryo, which is
the young plant itself.
dormant seed is defined as a viable seed that will not germinate when
exposed to the proper environmental conditions necessary for germination
of that plant species.
seeds from temperate woody species need a certain number of hours less
than 45 degrees F. in a moist environment before germination (and bud
break) can take place.
role of the seed sector is not only to ensure adequacy in seed quality
but also to ensure varietals diversity.
seed programme boasts one of the biggest seed markets in the world, with
annual sales at around US $920 million. Of this, domestic off take
accounts for US $900 million and sales in the global market account for
the remaining US $20 million.
is endowed with second largest area of farmland, and the largest area of
irrigated land, in the world and, with its huge germplasm diversity, its
seed industry is well placed to serve both domestic and international
to proprietary genes and technology is essential for developing and
commercializing genetically modified varieties. Dispute and uncertainty
over intellectual property rights have induced mergers, take-overs and
GM field trial activity has followed a similar trend to that seen in the
US, however the fall in field trial activity in recent years has been
even more pronounced.
