Gibberellins also play an important role in the tolerance
of plant to salinity by enhancing plant growth and yield
(Hayat et al. 2001; Siddiqui et al. 2008). An osmotic stress,

a reduction in gibberellins content (Kaur et al. 1998). Exogenous
GA could also cause an increase in germination and
seedlings growth, probably by enhancing the availability of
endogenous gibberellic acid (Kaur et al. 1998). Our results
showed that application of T. asperellum_______________
increased both the cucumber seedlings growth and the
content of GA in cucumber leaves, whether there was salt
stress or not.
