Summary: The study found that 6-BA can inhibit the increase in abscisic acid (ABA) content induced by waterlogging, increase the phosphorylation levels of proteins involved in ABA signaling, and enhance stomatal responsiveness to exogenous ABA. Additionally, the application of 6-BA has long-term effects on signal transduction pathways and helps in rapid responses to subsequent stresses.

Summary: Applying 6-BA can improve grain yield in densely planted maize by increasing grain weight through faster grain filling rate. It also enhances enzyme activities related to starch synthesis and alters endogenous hormone levels, promoting starch accumulation and improving grain filling. It is worth noting that inferior grains show a stronger response to exogenous 6-BA compared to superior grains.

Summary: This study investigated the effects of H2O2 priming on yield and photosynthetic parameters of summer maize. The results showed that H2O2 priming significantly enhanced the PSII photochemical efficiency, increased CO2 supply in dark reactions, and alleviated the damage caused by waterlogging to maize plant growth and grain yield.

Summary: Ensuring stable yield of staple grains is crucial to meet daily dietary energy needs in the face of global climate change. Summer maize, a staple crop, faces significant yield losses due to extreme rainfall events, impacting food security. Waterlogging at different stages affects plant growth, photosynthesis, and carbon partitioning, ultimately leading to poor spike development and high yield losses.

Summary: Waterlogging at different stages and durations has significant effects on maize growth and yield, with longer duration resulting in more severe adverse effects. Waterlogging at V6 stage has the greatest impact on maize growth and yield, and grain weight and grains per ear have the largest effect on grain yield.

Summary: This study found that exogenous 6-BA showed a mitigative effect on waxy corn under waterlogging stress. By modulating photosynthetic activities, 6-BA can protect the structural integrity of chloroplasts, enhance photosynthetic capacity, and promote stomatal opening. Additionally, it also promotes photosynthesis and increases carbohydrate accumulation.

Summary: This study investigates the effects of drought-flood abrupt alternation (DFAA) on summer maize production in the Northern Anhui Plain. Both field experiments and numerical simulations reveal significant negative impacts on biomass, grain yield, and quality, with root and shoot biomass reduction and yield loss. Historical and future simulations indicate an increasing annual yield loss rate due to DFAA.

Summary: Low planting density and irrational nitrogen fertilization are common practices in smallholder maize production in the Huanghuaihai region of China. A 2-year field experiment was conducted to study the effects of N application and planting density on maize phenology, dry matter accumulation, profit, yield, N uptake, and efficiency. The results showed that increasing N input and planting density delayed physiological maturity and enhanced dry matter accumulation. Optimal combinations of N application and planting density were found to increase grain yield, profit, and nitrogen use efficiency. Therefore, adjusting planting density and N application can enhance profit and nitrogen use in maize production.

Summary: The study found that waterlogging significantly decreases crop yield by reducing factors such as grain weight, biomass, plant height, photosynthetic rate, and leaf area index. The impact of waterlogging on crop yield varies depending on crop type, and the longer the duration of waterlogging, the greater the reduction in yield.

Summary: A 3-year field experiment in Northwest China found that applying ammoniated straw in maize cultivation can enhance water use efficiency, grain yield, growth characteristics, and soil water storage. The incorporation of ammoniated straw into the soil showed promising results in improving maize growth and sustainability in a semi-arid region.

Summary: This study characterized a yellow-green leaf mutant in maize caused by a mutation in the ZmCAO1 gene, which encodes chlorophyll a oxygenase. The mutant exhibited reduced chlorophyll concentrations, affecting photosynthetic processes and plant growth. Additionally, the mutation led to decreased grain yield and waterlogging sensitivity in maize, highlighting the pleiotropic role of ZmCAO1 in photosynthesis and stress tolerance.

Summary: Nitrous oxide (N2O) emissions from agroecosystems are a major contributor to global warming and ozone depletion. This study investigated the effects of manure application and irrigation on N2O emissions in a wheat-maize cropping system. The results showed that manure application reduced N2O emissions by 25-51% compared to chemical fertilizer, particularly during the two weeks after fertilization combined with irrigation. Furthermore, manure application maintained grain nitrogen yield, while increasing N2O emissions.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.

Summary: This study evaluated the changes in nutrient uptake, nutrient use efficiency, and yield of 20 cotton cultivars released in the USA between 1953 and 2018. The results showed that modern cotton cultivars have increased total nutrient uptake but slower improvement in nutrient use efficiency. The findings highlight the potential for enhanced nutrient uptake traits in cotton.
