Abstract
Chloris gayana Kunth is a grass species valuable as forage which was introduced into Argentina to be used as pasture in saline soils of subtropical and warm-temperate zones, given its good adaptability
to drought, salinity and mild freezing. However, its tolerance varies according to the cultivar. In tetraploid
cultivars, important reductions in yield have been observed. Here, a study of the variations produced on the
root and stem system by salinity at different NaCl concentrations (0, 150 y 250 mM) was performed in the
Boma cultivar, with the aim of determining the anatomical and morphological alterations produced by the
salt excess. Plants cultivated with the highest level of salinity showed, in the whole, significant differences in
the measured variables.
A diminution in absolute values of the variables and a major reduction in vascular tissue dimensions were
observed, which suggests that the lack of tolerance to salt stress could be related to a deficient adaptation to
absorb and transport water and nutrients from the roots.
