Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol) / Randomized block experiments were conducted to examine the putative amelioratory
effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in
Erucastrum strigosum plants subjected to a salinity series (0, 100, 200, 300, and 400 mM
NaCl) in the greenhouse. When the highest salinity concentration (increased stepwise)
was reached, growth effects in relation to water and cation content of the plants were
evaluated. Growth and water content were reduced progressively with salinity treatments.
Na+ concentration accumulated with salinity treatments to levels that were much higher
than that of other cations (K+, Ca2+ and Mg2+) in both organs. However, it is noteworthy
that Na+ distribution was more in shoots than in roots. In kinetin treated plants, shoot
growth decreased whilst root growth increased with moderate hormonal treatments.
