Among the abiotic stresses, drought is the first environmental stress responsible for a decrease in agricultural production worldwide; it affects plants in various ways, including slowing down plant growth and disrupting its general physiology. Arbuscular mycorrhizal symbiosis and plant growth-promoting rhizobacteria (PGPR) are considered to be the bioameliorators of the plant’s resistance to water stress. The present study investigated the effects of inoculation with arbuscular mycorrhizal fungi (AMF) and PGPR on the water status and antioxidant enzyme activities of date palm seedlings grown under water stress conditions. The parameters related to the plant’s water status were significantly ( p < 0.05 ) higher in the plants treated with mycorrhizae and mycorrhizae + bacteria compared with their respective controls, especially under water stress conditions. The maximum proline content was obtained in plants inoculated with the AMF species and PGPR (combined) under severe water stress conditions reaching a value of 2.588 ± 0.034 in 25% field capacity, compared with 0.978 ± 0.024 for the control. In addition, the inoculated seedlings showed notably lower activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), and glutathione S-transferase (GST) in response to severe water stress compared with nonmycorrhizal seedling. Overall, the arbuscular mycorrhizal symbiosis and PGPR bacteria inoculation could be promising methods to enhance date palm resistance against oxidative stress.

“…Aluminum chloride (AlCl 3 ) can produce metallic stress condition when added to culture media (Gallego et al, 2002). It enhanced shoot regeneration in date palm (Al-Mayahi, 2019), and increased micro-tuber and tuberous root production in Gloriosa superba L. (Subiramani et al, 2019). However, whether it can be used in orchid in vitro culture has not been reported yet.…”

We examined the effects of aluminum chloride (AlCl 3 ) on the organogenesis of Cymbidium Sweet Waffle 'Tarte' from inoculated protocorm-like bodies (PLBs) and of Cymbidium kanran 'Murotonishiki' from rhizomes to determine the appropriate concentration of AlCl 3 for organogenesis. The explants were cultured in modified MS media supplemented with various concentrations of AlCl 3 and maintained at 25Ϯ1℃ and a 24 h light period for 6 weeks for C. Sweet Waffle 'Tarte' and 10 weeks for C. kanran 'Murotonishiki.' In C. Sweet Waffle 'Tarte' 1.0 mg L Ϫ1 AlCl 3 significantly increased PLB formation, shoot formation from PLBs and root formation from shoot. In C. kanran 'Murotonishiki,' 1.0 mg L Ϫ1 AlCl 3 induced shoot from rhizome and developed roots from shoot. On the other hand, high concentration of AlCl 3 (10 mg L Ϫ1 ) resulted the formation of protocorm-like shoots in both Cymbidiums. We concluded that the concentration of 1.0 mg L Ϫ1 AlCl 3 is optimum for the root and shoot formation of the Cymbidium orchids.

“…Micropropagation is a promising way for obtaining large amounts of uniform plants that are disease-free and without pests during plant material exchange, genetically identical, and high-quality planting material. The increasing demand for rare and excellent quality date palm cultivars makes us use micropropagation as an unavoidable propagation method [ 1 – 3 ]. Plant tissue culture success as a plant propagation method is greatly influenced by the growth media composition [ 4 – 6 ].…”

Background Iron chelate sources and their concentrations are important factors in in vitro propagation of date palm. This study’s objective was to investigate the effect of the iron chelated form on the growth and development of tissue cultures of Barhee cultivar. Results The addition of FeEDDHA to the culture medium was more effective than FeEDTA on callus growth, shoot regeneration, and the number of shoots per jar, where the best result (220.8mg callus, 86.67% and 17.2 shoots per jar, respectively) was obtained by using 93.5 mg L−1 FeEDDHA (5.6 mg L−1 Fe), compared with other treatments. The results also indicate that using 93.5 mg L−1 FeEDDHA (5.6 mg L−1 Fe) as a supplement can decrease antioxidant enzymes CAT and POD activity compared to the rest of the treatments. Medium equipped with 187.0 mg L−1 FeEDDHA (11.2 mg L−1Fe) had the highest rooting percentage and number of roots per shoot than other treatments. The biochemical analysis results showed that treatments with FeEDDHA of 280.5 mg L−1 (16.8 mg L−1 Fe) and 187.0 mg L−1 (11.2 mg L−1Fe) significantly increased the iron content. The results showed that shoot maximum chlorophyll and endogenous IAA level content were recorded in a medium supplemented with 187.0 mg L−1 FeEDDHA (11.2 mg L−1Fe) as Fe source. Conclusion FeEDDHA used in the present study was proven to be a promising iron chelate source in comparison with the FeEDTA sources.
