The application of biostimulants in vegetable cultivation has emerged as a promising approach to enhance the nutritional quality crops, particularly controlled environment agriculture and soilless culture systems. In this study, we employed rigorous methodology, applying various amino acids, Plant Growth-Promoting Rhizobacteria (PGPR), fulvic acid, chitosan, vermicompost along with mineral fertilizers, both foliar via roots, greenhouse tomatoes during spring cultivation. experiment, conducted coir pith medium using ‘Samyeli F1’ tomato cultivar, demonstrated that plants treated performed better than control plants. Notable variations components were observed across treatments. PGPR had best effects on physical properties fruit, showing highest fruit weight, length, equatorial diameter, volume, skin elasticity, flesh hardness while maintaining high color parameters L, a, b. acid significant enhancements total phenolics flavonoids, suggesting potential boosts antioxidant properties. Amioacid notably elevated soluble solids, indicating sweetness overall taste improvements. On other hand, stood out for its ability elevate flavonoids enhancing vitamin C content, comprehensive enhancement quality. addition, most impact plant growth yield, achieving 43% increase over yield 10.39 kg/m2. These findings underline specific benefits different biostimulants, offering valuable insights optimizing practices produce enhanced health-promoting

Plant growth and production can be adversely affected by high temperature stress, which is defined as an increase in over a threshold level. 5-aminolevulinic acid (ALA) used beneficial regulator agriculture, particularly for plants experiencing abiotic stress. The efficacy of exogenous two form ALA application (bulk nanoencapsulated) was investigated factorial experiment based on completely randomized block design with 12 replications. In this study, different temperatures (optimal 25°C, 35°C) treatments were (control, 1 mM ALA, Nano-encapsulated N-ALA). study revealed that elevated 35°C had adverse impact the majority bell pepper characteristics. Nevertheless, N-ALA significantly enhanced characteristics under these conditions. contrast to conditions at concentrations potassium (K), proline, electrolyte leakage (EL), glucose, fructose exhibited 35°C. However, both forms effective mitigating effects. Comparatively, control treatment showed levels peroxidase (POD), superoxide dismutase (SOD), catalase (CAT) enzymes, along increased malondialdehyde (MDA) compared treatment. resulted highest fresh weight shoot length N-ALA. Conversely, same temperature, led 17% chlorophyll fluorescence 32% DPPH ALA. summary, effectively mitigates effects exposure biochemical parameters.

Tomato fruit are rich in γ-aminobutyric acid (GABA), which lowers blood pressure and improves sleep. An increase GABA content is important for enhancing the nutritional quality of tomato fruit. To investigate effects 5-aminolevulinic (ALA) on synthesis greenhouse tomatoes, cultivar (Solanum lycopersicum cv. '184') was used as an experimental material. During fruit-setting period, root drenching with 0, 10, 50 mg·L-1 ALA, foliar spraying 50, 100 surface 100, 200 ALA were applied. The study investigated application exogenous to different parts plant determine optimal concentrations each site (10 application, application). Using selected concentrations, tomatoes at sites tomatoes. results demonstrated that greenhouse-grown plants substantially increased single-fruit weight by 42.37%-76.24%, soluble sugar 78.51%-94.52%, solids 9.09%-41.71%, protein 82.71%-241.05%, ascorbic 1.31%-5.06% mature And it reduced organic 12.81%-33.61%. Moreover, applied enhanced free amino 11.22%-16.50%, among them, umami 7.26%-20.13%. Besides, fruits 214.58%-433.32 across parts. Exogenous regulates activity glutamate decarboxylase (GAD) increases pathway during development, thereby affecting content. In summary, metabolism acids enhances biosynthesis GABA, promotes nutrient

Chlorine Modulates Photosynthetic Efficiency, Chlorophyll Fluorescence in Tomato Leaves, and Carbohydrate Allocation in Developing Fruits

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(7), С. 2922 - 2922

Chlorine (Cl) is an essential nutrient for higher plants, playing a critical role in their growth and development. However, excessive Cl application can be detrimental, leading to its limited use controlled-environment agriculture. Recently, has been recognized as beneficial macronutrient, yet studies investigating impact on plant fruit quality remain scarce. In this study, we determined the optimal concentration solutions through series of cultivation experiments. A comparative analysis treatments at 1, 2, 3 mM revealed that Cl- significantly enhanced chlorophyll content, biomass accumulation, yield. Furthermore, examined effects (supplied 1.5 CaCl2 KCl) leaf photosynthesis, fluorescence, sugar metabolism. The results demonstrated activity Photosystem I (PS I) II II), 25.53% 28.37% increase net photosynthetic rate, respectively. Additionally, resulted 12.3% 16.5% soluble content mature tomato fruits. During development, promoted accumulation glucose, fructose, sucrose, thereby enhancing sweetness overall quality. observed glucose fructose levels was attributed stimulation invertase activity. Specifically, acidic (AI) increased by 61.6% 62.6% green ripening stage, while neutral (NI) elevated 56.2% 32.8% KCl treatments, respectively, maturity. sucrose synthase (SS-I) upregulated 1.5- 1.4-fold maturity, phosphate (SPS) 76.4% 77.8% during stage. These findings provide novel insights into metabolism, offering potential strategies optimizing fertilization practices protected horticulture.
