Summary: This study aimed to investigate the effects of nitrogen and phosphorus fertilization on alfalfa in the northern Xinjiang region. The results showed that combined nitrogen and phosphorus fertilization promoted the growth and hay yield of alfalfa, while nitrogen or phosphorus fertilization alone also had positive effects on its growth. Additionally, phosphorus fertilization increased carotenoid content in the leaves, while nitrogen and phosphorus fertilization enhanced stomatal aperture and antioxidant enzyme activity in the early flowering stage of alfalfa leaves.

Summary: In this study, the effects of cadmium (Cd) stress on the growth and physiological response of Elymus nutans Griseb. were investigated. The results showed that low concentration of Cd promoted the growth of the plant, while high concentration inhibited the growth. Cd stress also had a negative impact on the accumulation of chlorophyll.

Summary: Oxidative damage caused by aflatoxin (AF) in rat liver tissue was investigated, and the inhibitory effect of lycopene against this injury was demonstrated. Lycopene reduced malondialdehyde levels, increased glutathione levels, and enhanced antioxidant enzyme activities in the liver. This study suggests that lycopene can prevent AFB1-induced hepatotoxicity.

Summary: Human activities increase the risk of stable and radioactive strontium isotopes entering the environment and food chain. This study investigates the effects of strontium on lettuce by analyzing nutrient uptake, physiological responses, and the distribution of strontium in lettuce leaves. The results show significant differences in nutrient uptake, biomass, photosynthetic pigment contents, and antioxidant enzyme activities under different strontium treatment concentrations and times. The distribution of strontium in lettuce leaf tissues is also examined.

Summary: This research aimed to study the combined effects of water deficit and salt stress on triticale, focusing on various morpho-physiological and biochemical traits. The results showed that salinity and water deficit stress led to decreased yield and plant health, while also increasing oxidative stress and enzyme activity in triticale. The impact was particularly severe during flowering stage, highlighting its sensitivity to the dual stressors.

Summary: The study shows that foliar spray of sodium nitroprusside (SNP) on mustard plants can enhance photosynthetic efficiency, carbon metabolism, nutrient status, and activity of various enzymes related to nitrogen metabolism, CO2/HCO(3)(-) homeostasis, glycolysis, Calvin cycle, and Krebs cycle. Additionally, SNP application reduces reactive oxygen species and lipid peroxidation, while upregulating the antioxidative defense system.

Summary: Antibiotics, such as enrofloxacin, can affect the growth of pepper plants and induce biochemical responses. This study found that treatment with enrofloxacin led to decreased chlorophyll and carotenoid contents, increased activities of antioxidant enzymes, and altered levels of proline, glutathione, and malondialdehyde in pepper plants. However, exogenous treatment with ascorbate alleviated the negative effects of enrofloxacin and induced antioxidant defense responses.

Summary: This study investigated the mechanisms of photosynthetic, physiological, and yield variations among peanut cultivars under shading stress. S60 and P12 exhibited lower yield and biomass accumulation but higher light-trapping capability and antioxidant enzyme activities compared to C4 and YS151 under shading stress. The results suggest that non-stomatal limiting factors decrease the photosynthetic capacity of peanut under shading stress, and S60 and P12 show better light protection ability in weak light environments.

Summary: Research isolated 36 salt-tolerant plant growth-promoting bacteria (ST-PGPB) from sodic soil in India, with 13 strains showing better growth properties in high salt concentrations. Inoculation with Bacillus pumilus strain JPVS11 improved rice growth performance, chlorophyll content, and soil enzyme activities, indicating its potential as a beneficial bacterium for mitigating salinity effects in rice.
