At the beginning, they both start in 100%, later on, NVP
descends further to reach 58/59% but ZDV stays in 62%.
Then, when they both reach the 100 umol NVP affects
the root growth less than the ZDV. They end up affecting
it the same in 200 umol. After this, we realise that ZDV
influences and decreases the root length more than the
NVP.

Because even if it has the influence of drugs in it, the mitosis
that was happening before these got in the way, is still
happening and is going to be able to finish the process .
Because of the tissue being damaged the
mitotic index grows so it can heal what was
damaged.
