It is my understanding that monocot roots do not branch if the
growing tip is injured, unlike dicots. Injure a monocot root and the
damage can only be made good by an altogether new root growing from
the basal plate (or equivalent organ) -- and that may not happen
until next growing season. Hence the need to be much more careful
with monocot seedlings, to handle them much more gently.
I was surprised to read that. From everything Ive read, Monocots always abort the radicle root, and depend entirely upon an adventitious root system. So, cutting the first root may be a non-issue as long as the adventitious system has started. Again, my understanding is that the adventitious system is initiated shortly after germination.
