Melatonin (MT) is an important biologically active hormone that plays a vital role in plant growth and development. In particular, it has been investigated for its roles abiotic stress management. this study, pepper seedlings were subjected to low-temperature combined with low-light (LL) (15/5°C, 100 μmol m-2s-1) prior foliar spray of 200mM MT 168h investigate the protective seedlings. Our results demonstrated LL negatively affected root growth, accelerated accumulation reactive oxygen...

Cadmium (Cd) contamination is a serious global concern that warrants constant attention. Therefore, hydroponic study was conducted to evaluate the effect of different concentrations (0, 1, 2.5, 5, 10, 15 mg/l) zinc oxide nanoparticles (ZnONPs) on Cd content in lettuce ( Lactuca sativa L. ) under stress conditions. The results showed triggered decrease plant biomass, an increase relative electrolyte conductivity (REC), root activity, accumulation reactive oxygen species (ROS) accumulation,...

Methyl jasmonate (MeJA) and salicylic acid (SA) regulate the production of biologically active compounds in plants stimulate accumulation plant aromatic substances. However, underlying mechanisms how MeJA SA influence characteristic flavor antioxidant activity vegetables are poorly understood. Five concentrations were used to investigate dose-dependent effects these phytohormones on dry fresh weight; chlorophyll abundance; contents vitamin C, soluble protein, sugar, nitrate, total phenols,...

Trehalose (Tre), which was an osmoprotective or stabilizing molecule, played a protective role against different abiotic stresses in plants and showed remarkable perspectives salt stress. In this study, the potential of Tre improving resistance to stress tomato investigated. Tomato (Micro Tom) were treated with Hoagland nutrient solution (CK), 10 mM (T), 150 sodium chloride (NaCl, S), Tre+150 NaCl (S+T) for 5 days. Our results that foliar application alleviated inhibition plant growth under...

The wrinkled pepper (Capsicum annuum L.) is a type of chili domesticated in northwestern China, with characteristic flavor. Fifteen and four smooth-skinned varieties were evaluated for morphology, texture, color, nutrients, capsaicinoids, volatile compounds at the mature fruit stage. sensory evaluation showed was superior to smooth it has highly significant correlation (p < 0.01) cuticle thickness, maximum penetrating force, lignin content, moisture content. Citric acid major organic...

Cherry tomatoes are popular vegetables worldwide owing to their variety of colors and nutrients. However, an integrated evaluation color flavor has rarely been reported. This study examined the differences among red, brown, yellow, green cherry grown in Jiuquan area. A comprehensive analysis quality these tomatoes, including sensory evaluation, electronic nose analysis, nutritional measurements, targeted metabolomics, chemometrics, was conducted. Red had highest lycopene content, soluble...

Excessive application of fertilizers leads to the loss a high amount nutrients and low fertilizer utilization, which severely restricts crop productivity. Establishing better usage practices can mitigate adverse effects excessive use in agricultural practices.
