when I was isolating tobacco leaf chloroplasts advise given to me was to
keep the leaves overnight in the dark so that starch was consumed.  Maybe
you could do the same with the roots?

Or maybe you need to wash the roots extensively to get rid of the root cap
mucilage before extraction.

Why do you want ROOT nuclei?  Regards, Mike.
