e0“The in vitro responses of date palm (Phoenix dactylifera L.) callus of Hillawi cv. to Aspergillus niger culture filtrates (ACF) (10 and 20%) and sodium chloride (68.45; 137 and 205.34 mM) treatments were investigated at proliferation stage”
e4“The exposed callus generally tends to accumulate a significant amount of free proline as well as hydrogen peroxide. This accumulation increased significantly with the increase of ACF and NaCl concentrations”
e5“whereas the opposite trend was seen in the activity of Catalase”

Other claims from this paper (7)
- Intervention effect High concentrations of Aspergillus niger culture filtrate decreased fresh and dry weights of date palm callus compared with untreated callus.
- Intervention effect High concentrations of sodium chloride decreased fresh and dry weights of date palm callus compared with untreated callus.
- Observation Growth reduction of date palm callus was accompanied by an increase of browning intensity.
- Intervention effect A low concentration of NaCl (68.45 mM) stimulated date palm callus growth.
- Intervention effect Free proline and hydrogen peroxide accumulation increased with ACF and NaCl concentrations in date palm callus.
- Observation RAPD analysis detected DNA polymorphism, with appearance and disappearance of fragments, in stressed date palm callus compared with the control profile.
- Mechanism Genetic rearrangements may cause the observed morphological and biochemical variations in date palm callus.
