Results and discussion
Both studied species suffered morphological alterations at radicle
level due to direct contact with different parts of A. dealbata;
particularly, the root hair zone revealed notable damage. In case of
L. sativa, abundant root hairs were produced by control (Fig 1A),
which allows that seedlings could absorb water and grow normally.
However, A. dealbata pods prevented formation of root hairs
and damaged the rhizodermis tissue (Fig. 1B). The effect caused by
leaves of A. dealbata on radicles of L. sativa was similar, although a
more intense rhizodermis tissue destruction was detected (Fig 1C.),
meanwhile seeds reduced considerably the root hairs formation
and large spaces were uncovered at the rhizodermis level (Fig. 1D).
