<div>I'm attaching Figure 6 (page 14).</div>

<div>The seminal (secondary) root here is also growing upwards, but
clearly emerging from the scultellar node (embryo axis).</div>
<div><br></div>
<div>On page 16-17 in a description of the root system, it says:
"The root system of corn, as of other grasses, consists of two
sets of roots: (1) seminal roots whose initials are present in the
embryo, and (2) adventitious roots, which arise from stem tissue after
germination...."</div>

That was my concern but since there seems to be some dispute here
amongst my betters:<br>
Do you have a picture or published reference I could go to for
this?<br>

I've looked at a lot of these roots in my day, and it is true that in
some backgrounds, they tend to grow upwards and appear as if they're
emerging above the scutellum. <font color="#008080">However,
they're really originating from within the scutellum (or the embryo
axis proper).</font></blockquote>
