# vivipary is a instance of seed_hgermination (on parent plant)

# A correct balance of Gibberellic acid (GA) and Abscisic acid(ABA) is 
required in maturing seed (dormant stage) prevents vivipary.

# GAs stimulate a developmental program leading to vivipary in the 
absence of normal amounts of ABA, and that a reduction of GA content 
re-establishes an ABA/GA ratio appropriate for suppression of 
germination and induction of maturation. In contrast, the induction of a 
GA deficiency did not suppress vivipary.

Therefore here is a suggestion:

In the suggestion, I have considered to use VIVIPARY exclusive to the 
use of plants. Perhaps this may require sensu Mangnoliophyta term if 
users consider that they need a term to represent the similar phenomenon 
from metazoans. Looks like pregnancy is analogous to vivipary. Since 
this is seed specific term you may want to use the words "germination of 
the embryo from a seed" in the definition, thus excluding the so called 
vivipary (vegetative propagation) as seen in bryophyllum.

This term exists as a child of (seed dormancy GO:0010162) and looks like 
it needs obsoletion, if the above tree under seed dormancy is adopted. 
Basically maintenance of dormancy = positive regulation of dormancy.

I did not use the XX-acid mediated signalling terms as parent terms 
because the literature does not use the word signalling. Perhaps it is 
but I am not sure.
