Discovering new genes for alfalfa () growth and biomass resilience in combined salinity and infection through GWAS.

Salinity and infection represent significant challenges for alfalfa cultivation in South Africa, Europe, Australia, and, particularly, Tunisia. These constraints have a severe impact on both yield and quality. The primary aim of this study was to establish the genetic basis of traits associated with biomass and growth of 129 genotypes through genome-wide association studies (GWAS) under combined salt and infection stresses.

Improving productivity and soil fertility in Medicago sativa and Hordeum marinum through intercropping under saline conditions.

Background And Aims: Intercropping is an agriculture system used to enhance the efficiency of resource utilization and maximize crop yield grown under environmental stress such as salinity. Nevertheless, the impact of intercropping forage legumes with annual cereals on soil salinity remains unexplored. This research aimed to propose an intercropping system with alfalfa (Medicago sativa)/sea barley (Hordeum marinum) to explore its potential effects on plant productivity, nutrient uptake, and soil salinity.

Evaluation of L. Plant Food Safety after Lead Exposure: Phytochemical Processes.

Lead stands as a food contaminant through its accumulation in consumed plants. In this study, the effects of lead (II) chloride (PbCl2) and its levels of uptake on morphological and phytochemical responses of fenugreek were assessed to evaluate its tolerance and safety for human consumption. Results revealed that PbCl2 (50−2000 mg L−1) did not affect the germination rate, but it decreased the radicle length and amylase activity.

Priming with EDTA, IAA and Fe alleviates Pb toxicity in Trigonella Foneum graecum L. growth: Phytochemicals and secondary metabolites.

This study evaluated the effects of the exogenous application of ethylenediaminetetraacetic acid (EDTA), indole-3-acetic acid (IAA) and iron sulfate (FeSO) upon the phytochemical mechanisms of fenugreek grown under Pb-excess (2000 mg L PbCl). The results showed that chemical additives of EDTA and IAA as well as FeSO improved fenugreek germination parameters. The radicle length and the amylase activity were significantly improved under IAA treatment compared to EDTA and FeSO.
