plantlet formation

[kellogge]

Seed germination on the parent plant is caused by reduction in or 
insensitivity to abscisic acid levels.  I don't know about the other 
process, and there may not be information on it;  I suspect if there is 
information it will be in the horticultural literature, rather than the 
agronomic literature.
