ACAMOSPERMY Agamospermy, asexual production of seeds, is a phenomenon
absent in gymnosperms and limited to a small group (34 families) of angiosperms
, occurring mainly in the Compositae, Gramineae, and Rosaceae (Asker and ...

One step above such an asexual survival strategy is that of apomixis via
agamospermy. In plants which exhibit agamospermy, seeds may be formed
without the requirement for pollination. The embryo is formed from the female
gamete without ...

INTRODUCTION Asexual reproduction in seed plants (apomixis) can be divided
into two main classes; vegetative reproduction and agamospermy. Vegetative
reproduction was dealt with in Chapter 10 of the first edition of this book (1986).

agamospermy refers to the production of fruits and seeds by non- fertilised

Comprehensive Biology XII
It is called agamospermy (Gk. agamous = without marriage, sperma = seed).
Sometimes a diploid embryo sac is developed from diploid megaspore mother
cell or nucellus or integument. Thus, the egg developed in such embryo sac is
diploid.

Variation and Evolution in Plants and Microorganisms:: ...
Ideas about the evolution of agamospermy and apogamy in plants tend to focus
on the genetic consequences of agamospermy and the mech- anisms by which it
might arise (Mogie, 1992). In flowering plants, for example, agamospermous ...

Genomes of Plants and Animals
Thus, distinguishing offspring produced via agamospermy versus via selfing
depends on the occurrence of at least some loci that are heterozygous in the
pistillate plant. But how many heterozygous loci are needed in the "maternal"
plant to ...

However, experimental treatments testing for geitonogamy and xenogamy
produced a significantly higher proportion of nonpolyembryonic seeds than tests
for agamospermy (Schmidt and Antlfinger 1992). They considered that
agamospermy ...
