Question on part of seedling

[Pankaj Jaiswal]

Hi Everyone,

Thank you for your responses. Here are some of the definitions I found in the 
literature.


CROWN -

1
part of the wheat/barley plant located about 0.5 inches below the soil surface. 
The crown is where the nodes are tightly packed together, tiller buds develop, 
and coronal root buds develop.

2
Located between the coleoptile and the mesocotyl, the crown contains the growing 
point where the rest of the plant will begin to form and the nodes where the 
nodal or permanent roots will form.

I think we might have to create new term "germinating/juvenile seedling" as an 
instance of "vegetative shoot", in order to introduce "crown" as part of it.

Any suggestions ?
