Summary: This study aimed to investigate the effects of indole acetic acid (IAA) and Citrate Capped Silver Nanoparticles (Cit-AgNPs) on various attributes of maize under salinity stress. The nanoparticles were analyzed using scanning electron microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), Thermo-gravimetric analysis (TGA), and Differential thermal analysis (DTA). The results showed that the foliar application of IAA and Cit-AgNPs significantly improved the agronomic attributes, photosynthetic pigments, osmolytes, and antioxidant enzymes in maize plants under high salinity stress.

Summary: Pot experiments were conducted to investigate the alleviating effect of biochar on arsenic (As) toxicity in soybean plants. The results showed that biochar application effectively mitigated the inhibitory effects of As on soybean growth, with a more significant effect observed in plants subjected to higher As treatment. Biochar reduced As uptake and minimized the decrease in chlorophyll and carotenoid content. Osmolyte concentrations increased with biochar application. Biomarkers such as membrane stability index, hydrogen peroxide, and malondialdehyde significantly decreased at higher As levels with biochar application, indicating improved plant health. Antioxidative enzymes also showed an increase in activity upon addition of biochar.

Summary: This study provides a comparative analysis of 24 rapeseed cultivars under drought conditions, revealing their potential for drought tolerance and the mechanisms involved. It was found that tolerant cultivars exhibited higher efficiency in enzymatic and osmoregulatory mechanisms compared to sensitive cultivars. Results also showed that JYZ 158 and FY 520 cultivars had higher drought tolerance and could be important germplasm resources for breeding drought-tolerant rapeseed.

Summary: Water is a crucial component for the existence of life on Earth. However, extreme climate changes have led to water scarcity in many regions, posing significant challenges. This review aims to analyze and understand the physiological and biochemical responses of plants to drought stress and their ability to mitigate its damaging effects. It also explores the role of plant hormones in drought stress responses and signaling. The information for this review was gathered from various sources, including global search engines and scientific literature databases.

Summary: The study investigated the effects of exogenous NO and proline on the protection of wheat plants from heat stress. Heat-stressed plants showed increased oxidative stress and proline accumulation, as well as elevated levels of ethylene and NO generation. The application of SNP and proline improved photosynthesis and reduced oxidative stress in heat-stressed plants by enhancing the antioxidant defense system.

Summary: This study evaluated the effects of different tillage, nitrogen fertilization, and crop rotations on soil physicochemical and biological properties in an Andean soil. Results showed that no-tillage and crop rotation significantly influenced soil properties. No-tillage promoted soil respiration, glomalin content, and the density of arbuscular mycorrhizal fungi spores. The conservative soil management system demonstrated significant improvements in soil properties compared to intensive soil management.

Summary: Agricultural soil quality has been extensively discussed in recent decades. This study focused on three olive grove areas in Portugal with different management techniques, aiming to assess the influence of these techniques on soil quality. The results showed that the concentrations of organic carbon and total nitrogen were highest in the intensive olive grove in Lisbon, while Ca, Mg, Na, and K were the main differences between Lisbon and the other two groves in Santarem. Enzymatic activities were found to be related to various soil concentrations. Soil management and agricultural practices were identified as determining factors for enzymatic activities in the olive groves.

Summary: The study found that tolerant genotypes of tea plants maintained better water relations, higher photosynthetic pigments, and reduced membrane injury compared to susceptible cultivars under water deficit conditions. Additionally, the lower efficiency of antioxidative enzymes in susceptible cultivars made them more prone to oxidative damage, while the accumulation of osmolytes played a significant role in drought tolerance.
