Trichoderma harzianum-fertilizer enhances the tolerance of date palm seedlings against soil salinity

الملخص EN

This experiment has studied the role of Trichoderma harzianum (TH-fertilizer) at 30 and 60 g kg-1 soil to improve the tolerance of date palm seedlings (Barhee cv.) against different salinity levels at 0, 75, and 150 mM NaCl in sandy soils.

Salt stress reduced plant height, root length, and leaf and root numbers.

On the other hand, TH-fertilizer improved these parameters and the chlorophyll and dry matter.

Application of 60 g kg-1 soi-1 had a better effect on seedling growth than 30 g kg soil-1.

Salt treatments increased the malondialdehyde, and hydrogen peroxide content, which was decreased with TH-fertilizer treatments.

TH-fertilizer increased proline, soluble proteins, catalase, ascorbate peroxidase, peroxidase enzyme, K, and Na/K ratio, whereas abscisic acid decreased under salt stress.

Therefore, TH-fertilizer has effectively adjusted plant growth under such conditions.

following review seeks to shed some light on certain specifics about the biology, pathogenicity, physical traits, and significant secreted metabolites of the hosts of this fungus.
