“…According to the results of the study, germination characteristics were significantly decreased with the level of lead acetate concentration. Many researchers have extensively described the toxic effects of cereals [19][20][21][22] . Different heavy metal concentrations have different phytotoxic effects on seed germination and seedling growth in diverse crops.…”

Lead (Pb) is one of the noxious trace metal element (TME) contaminants in the environment. In this work, we conducted a comparative physiological response study through some germination parameters between four cereals (Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays) grown on a nutrient solution for 10 days and treated with three increasing levels of lead acetate (0.15, 0.3, and 0.6 g/L) in order to evaluate the impact of different lead concentrations on the germination capacity of these species. The results showed that lead has an abiotic stress effect on the four varieties examined at 0.3 g/L and 0.6 g/L. We recorded a significant to very highly significant effect in all the parameters studied. In the underground parts, in particular, a highly significant reduction in precocity of germination was recorded in Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays. There was also a highly significant to very highly significant decrease in germination percentage in durum wheat, soft wheat, and maize. Under the most severe stress conditions (0.6 g/L), the barley variety showed stress tolerance with a germination rate of 92%. According to the findings of this study, the varieties examined can be grouped into two categories: variants that are susceptible to metal stress (Triticum durum, Triticum aestivum, and Zea mays) and varieties that are tolerant to lead exposure (Hordeum vulgare).

“…with researchers attempting to comprehend the evolution of Plant biodiversity over time and the factors that influence its spatial distribution [1]. Abiotic environmental factors have a significant impact on the distribution and performance of plant species [2][3][4]. Abiotic variables regulate plant population dynamics and community features in dry or semi-arid habitats [5].…”

The semi-arid is a climate characterized by precipitation that is. insufficient to maintain crops and where evaporation often exceeds rainfall. Vegetation is one of the most sensitive indicators of environmental changes understanding the patterns of biodiversity distribution and what influences them is a fundamental pre-requisite for effective conservation and sustainable utilization of biodiversity. In this study. our focus was on examining the vegetation diversity in the semi-arid region of Tebessa. which falls within the Eastern Saharan Atlas domain in North Africa’s semi-arid zone. Plants were sampled at 15 sites distributed across the study area. The quadrat method was used to conduct floral surveys. The sampling area of each sample was 100 square meters 10 m × 10 m (quadrat). Each quadrat was measured for species richness (number of species). abundance (number of individuals). and Richness generic (plant cover). Based on the floristic research. 48 species were found. classified into 21 families. with Asteraceae accounting for 34.69% of the species and Poaceae accounting for 14.28%.

Background and Aims Using organic amendments proposes a cost-effective solution to reduce cadmium mobility and uptake by plants under polluted soil. Methods Various organic amendments namely peanut shell (PN), sunflower shell (SF), walnut shell (WL) and peas peels (PS) once at a rate of 10% was applied to investigate whether and how plant growth of wheat (Triticum durum Desf. var. VITRON.) was affected when growing in Cd (50 mg kg− 1) contaminated soil, along with control in which distilled water was used without Cd contamination. This effect was evaluated through germination parameters (germination kinetics, germination speed, germination rate and emergence rate), growth parameters (leaf area, total weight, total plant length, shoot and root length, number of roots and leaves) and physiological parameters (relative water content, relative electrolyte leakage, membrane stability index, total chlorophyll content, soluble sugar, protein and proline content). Results The results showed that stressors significantly decreased the vegetative growth parameters, altered speed germination (p < 0.05), total plant weight (p < 0.001), membrane stability index (p < 0.05), leaf area and shoot length (p < 0.001). However, application of organic amendments seems to attenuate the negative effects of the Cd stress by the improvement of germination speed, total weight, membrane stability, leaf area, plant length, number of roots, relative water content, total chlorophyll content, proteins, proline and soluble sugar content in roots. Conclusions Overall, the application of PN or WL was more efficient in decreasing Cd effect in leaf and roots of wheat as compared to other organic amendments.
