Summary: This study investigated the effects of nickel application on physiological and biochemical attributes of sunflower cultivars grown in sand culture. Results showed that increasing nickel concentration significantly decreased vegetative parameters and photosynthetic attributes, while low levels of nickel improved growth attributes to some extent. The study also found that high nickel concentration had negative effects on leaf water potential, osmotic potentials, and relative water contents, but increased leaf turgor potential and membrane permeability. Hysun-33 exhibited higher tolerance to nickel stress compared to SF-187.

Summary: This study investigates the impact of sooty mould on tea plants and the recovery of plants by exogenous melatonin. The results show that sooty mould reduces photosynthetic pigments and gas exchange parameters in tea plants. On the other hand, exogenous melatonin inhibits mycelial growth of sooty mould and improves the growth and defense mechanisms of tea plants.

Summary: This research focused on using ornamental plants Helianthus annuus and Tagetes erecta for the phytoremediation of zinc-contaminated soil. The findings showed that Helianthus annuus had a better ability to mitigate zinc compared to Tagetes erecta. It is suggested that Helianthus annuus can be used as an effective accumulator of zinc in soil cleanup.

Summary: The study found that the accumulation of Cr(VI) was two to three times higher in roots than in shoots, indicating that the root is the major site of Cr(VI) accumulation. Under Cr(VI) toxicity, photosynthetic pigments, leaf gaseous exchange parameters, and F-v/F-m efficiency worsened. Cr(VI) accumulation intensified lipid peroxidation by triggering the production of MDA and H2O2, but the plant responded effectively by enhancing the coordinated action of enzymatic and non-enzymatic antioxidants.

Summary: Elevated salt concentrations in soil and water can restrict plant productivity, but foliar application of alpha-tocopherol can help overcome this issue. A pot experiment was conducted to determine the optimal application rate of alpha-tocopherol for sunflower grown in salt-affected soil. Results showed that a foliar application rate of 100 mg/L-alpha-tocopherol significantly increased shoot and root growth under salt stress, while a rate of 200 mg/L was most effective in improving chlorophyll content. These findings suggest that 100 mg/L and 200 mg/L are the best application rates for enhancing sunflower growth and chlorophyll content.

Summary: The concerns on weed control through herbicides are increasing due to their negative impacts on environment and human health. Therefore, alternative weed management methods are inevitable for sustainable crop production and lowering the negative consequences of herbicides. This study evaluated the role of different mulching treatments on suppressing weed flora in maize and sunflower crops. The results showed that plastic mulch and paper mulch had the highest suppression of weed flora compared to other treatments and significantly improved the productivity of both crops.

Summary: The study showed that the ectomycorrhizal fungus Scleroderma bermudense can improve the salt tolerance in Coccoloba uvifera L. (seagrape) seedlings. There were no significant differences in growth performance, nutritional and physiological functions between the two ECM seagrape provenances under salt stress. The beneficial effects of ECM symbiosis on photosynthetic rates, chlorophyll content, stomatal conductance, and water status led to improved growth performance of the seagrape provenances under salt stress.

Summary: This study investigated the phytotoxicity of lead (Pb) and accumulation potential in Limbarda crithmoides and Helianthus annuus. The results showed that Pb doses enhanced the biomass production in Limbarda crithmoides shoots and roots, while Helianthus annuus showed modest variation. Phenolic compounds and flavonoids were increased in both species under Pb treatment. Pb accumulation was higher in roots than shoots, with low translocation factor. The two species exhibited tolerance to Pb stress but were not classified as hyperaccumulators.

Summary: Global climate change exacerbates water scarcity in semi-arid regions, impacting agricultural production. Cowpea, a crop of socio-economic importance in the Brazilian semi-arid region, can adapt to water restriction through physiological mechanisms and the application of elicitors, contributing to maintaining crop yield under different water scenarios. However, the careful exploration of elicitor use in cowpea is necessary due to genotypic and edaphoclimatic variability in field conditions.

Summary: The palm tree Copernicia prunifera has been impacted by the invasive climbing shrub Cryptostegia madagascariensis. The adaptability to abiotic soil constraints mainly defines the competitive interaction between the two species. Cryptostegia madagascariensis is more competitive in flooded, salt-affected soils, and is not severely impacted even with high sodium accumulation in its leaves.

Summary: This study aimed to evaluate the effects of silicon foliar spray on the induction of tolerance to water stress in cowpea genotypes. The results showed that under water stress conditions, both cowpea genotypes, BRS Rouxinol and Costela de Vaca, had significantly reduced crop production variables. However, compared to the treatment without silicon spray, spraying with 49 mg/L and 70 mg/L of silicon increased the dry mass of pods + grains in the Costela de Vaca genotype by 131% and 38%, respectively. Silicon can mitigate the negative effects of water stress in cowpea plants, but their physiological and biochemical responses, as well as their agronomic performance, are related to the sensitivity of the genotype and their phenological stages. The Costela de Vaca genotype showed better tolerance to water stress.

Summary: This study evaluated the morphophysiology and mineral contents of watermelon crop under different electrical conductivity of irrigation water and planting methods. The results showed that direct seeding method obtained the highest biomass accumulation, salt stress increased the intrinsic water use efficiency in watermelon plants. Different planting methods had an impact on the contents of P and K in the leaf, while the increase in salinity level increased the content of S and reduced the content of Cu and Mn.

Summary: Global climate changes have increased water stress in arid and semi-arid regions, reducing plant growth and yield. This study aimed to evaluate the mitigating effect of salicylic acid and methionine on cowpea cultivars under water restriction conditions. The results showed that water stress decreased leaf area and fresh mass, and increased total soluble sugars and catalase activity. BRS Pajeu showed higher tolerance to water stress compared to BRS Novaera. The application of salicylic acid and methionine had a stronger effect on BRS Novaera, stimulating its tolerance mechanism to water stress.

Summary: Salicylic acid (SA) can induce physiological and metabolic changes in plants, enhancing their tolerance to saline stress and enabling the use of saline water in semi-arid regions. This study evaluated the impact of foliar application of SA on mitigating salt stress effects on Japanese cucumber in a hydroponic system. Results showed that foliar application of SA at concentrations between 1.4 and 2.0 mM reduced the detrimental effects of saline stress and improved cucumber fruit production and post-harvest quality.

Summary: The aim of this study was to assess the water storage dynamics in typical trees of the Caatinga biome by measuring the water content levels that trigger leaf emergence. Low-cost capacitive sensors were used to monitor soil and stem water content of representative species catingueira (Caesalpinia pyramidalis Tul.). The study found that catingueira plants can absorb water below the usual soil water potential for permanent wilting, and the volume of water stored in the plants exceeds the average volume stored in the Boqueirao reservoir during the study period.
