Abstract: | Summary Corn plants were grown in pots to study the effect of post-planting loosening of an unstable sandy loam soil on the anatomy
of roots. Roots from compact soil had more elaborate production of sclerified cells in the cortical and vascular tissue which
may be considered as traits developed in such roots to resist external forces to prevent the deformation of interior cells.
It appears that the compact layer that developes on unstable soils after irrigation, hinders the normal development of root
structure. Its loosening decreases soil resistance and permits normal development of root anatomy. |
