Summary: Rising salinity poses a significant threat to crop production, but exogenously-applied salicylic acid can alleviate the negative impacts of salinity on crops. A factorial pot experiment was conducted to evaluate the effects of salicylic acid on baby corn under salt stress. The results showed that increasing salinity levels had detrimental effects on growth, physiological traits, and yield of baby corn, but seed priming with salicylic acid improved some of these parameters at moderate levels of salinity.

Summary: The study analysed the interaction of Maize and Cattail under waterlogging and field capacity conditions. The experiment showed that waterlogging was detrimental to maize, but Cattail increased the dissolved oxygen content and benefited maize, showing no competition between the two.

Summary: Waterlogging stress in maize affects dry matter translocation, leading to reduced yield; different inbreds exhibit contrasting responses, with tolerant inbreds developing aerenchyma cells for enhanced tolerance. Upregulation of adaptive genes during waterlogging, coupled with increased energy consumption, may shorten plant survival.

Summary: This study investigated the stimulatory effects of the plant growth regulator ethephon on the morpho-physio-biochemical traits of maize under water stress conditions. Results showed that ethephon application, particularly the E3 approach, improved the yield and growth characteristics of maize, especially under appropriate water stress conditions.

Summary: This study investigated the structural mechanical properties of brace roots in maize from different whorls, genotypes, and reproductive stages. The results showed that brace root mechanics varied depending on whorl, genotype, and reproductive stage. Specifically, brace roots from the first whorl had higher structural mechanical properties, while senesced brace roots had lower properties. These findings are important for mitigating crop loss due to root mechanical failure.

Summary: The study highlighted the impact of water scarcity on cotton growth and productivity, emphasizing the urgent need for a solution. Through evaluating 23 genotypes for drought tolerance at the seedling stage, significant differences were found in morphological and physiological traits, with interactions between genotype and water regime affecting traits like root length, shoot length, excised leaf water loss, and stomatal conductance. Positive correlations were found between transpiration rate and relative water content, as well as between relative water content and photosynthesis, under drought conditions. Negative correlations were found between stomatal conductance and shoot length, as well as between stomatal conductance and photosynthesis. These findings suggest potential indicators for differentiating drought-tolerant genotypes and the possibility of developing breeding strategies using specific varieties such as NIAB-135, NIAB-512, and CIM-554.

Summary: This study used in situ maize-phenology data from three different sources to establish a maize-phenology data set, including nine phenological stages and phenological stage maps. The relationship between each phenological stage and date, longitude, latitude, and altitude was revealed using multiple stepwise regression and the spatial variation of each phenological stage was explored using ArcGIS. The validated data set can be used for various purposes, including real-time warning and prediction of maize-related meteorological hazards.

Summary: This study investigates the effect of Rhizophagus irregularis on the expression of plasma membrane aquaporin isoforms in maize leaves under severe drought conditions. The findings show that the regulation of aquaporins by mycorrhiza is dependent on leaf position and is closely related to photosynthesis and stomatal response to drought. The results suggest that mycorrhiza protects the leaves from drought effects by preventing the down-regulation of aquaporins, leading to improved stomatal conductance and faster restoration of photosynthetic capability.

Summary: This study investigated the effects of brassinosteroids on drought resistance in different maize genotypes at physiological and transcriptomic levels. The results showed that plant hormonal signal transduction and starch and sucrose metabolism were enhanced in all genotypes, while phenylpropanoid biosynthesis was enhanced in the more drought-tolerant genotypes. This study provides valuable information on drought-responsive mechanisms and candidate gene resources for maize improvement.

Summary: Improvements in agricultural production are necessary due to the increasing human population and its impact on climate. Water scarcity limits maize yield in many regions. Seed mortars, particularly those containing succinate dehydrogenase inhibitors, can mitigate the negative effects of drought on maize development. This study compared 12 seed treatments and found that treatments with SDHI significantly improved root system development, photosynthesis, and chlorophyll fluorescence parameters in maize under drought stress.

Summary: High temperature stress negatively impacts plant growth, but arbuscular mycorrhizal fungi (AMF) can protect plants by improving physiological parameters and soil microbial communities. This study shows that maize plants with AMF have higher photosynthetic efficiency and lower lipid peroxidation under high-temperature stress, indicating a role of AMF in enhancing plant tolerance to heat. The research highlights the importance of considering both above- and below-ground traits in understanding plant responses to stress.

Summary: This study aimed to evaluate the salt tolerance of 15 maize genotypes during early growth under salt stress. The results showed significant variation in salt tolerance among the genotypes, with some genotypes exhibiting better ability to cope with salt stress. The findings from this study can be valuable for future breeding programs to develop high-yielding maize hybrids under salt stress conditions.
