Includes bibliographical references
Populus nigra plants were subjected to four soil salinity levels (0. 0,3.0, 5.0 and 7.0 dSm-1)
in a pot experiment with two types of nutrients foliar applications
(silicon at 100 and 200 mg/l and glycine betaine at 200 and 400 mg/l).
Salinity treatments reduced all growth characters. On the other hand, sugars,
proline, Na and Cl contents increased by increasing salinity levels, while chlorophylls,
N, P and K diminished. Foliar application of silicon or glycine betaine enhanced all the
studied growth characters, as well as the organic (sugars, proline and chlorophylls)
and inorganic components (N,P and K), while Na and Cl decreased. The combination of
Si (200 mg/l) + GB (400 mg /l), gave the best results, alleviating the adverse salinity
effects on the growth and development of Populus nigra.
Key words: Populus nigra , salinity , glycinebetain.
