plantlet formation

[J Clark]

Hi Toby,

Thanks for that information.

If seed germination on the parent plant is caused by reduction in or 
insensitivity to abscisic acid levels
then perhaps normal 'maintenance of seed dormancy' could be a child of 
'response to abscisic acid' and that 'seed germination on parent plant' 
should not be connected to a hormone term since the hormone is not 
acting in this case.

Does that seem right to you?

Thanks,

Jen
