The effect of β-1,3-glucan on the photosynthetic apparatus and oxidative stress parameters of tomato (Lycopersicon esculentum Mill., cv. Tamara) leaves under fusarium wilt caused artificially by the fungal pathogen Fusarium oxysporum sp. was studied in 2-month-old tomato plants. Infection of tomato plants with a pathogen causes activation of lipid peroxidation (LPO) processes in leaves and significant changes in the photosynthetic apparatus, which is reflected in a decrease in the chlorophyll (Chl) a and Chl a/Chl b ratio and carotenoid content, disturbances in the absorption and utilisation of light energy in PSII. Pretreatment of plants with β-1,3-glucan contributes to the stabilisation of LPO and normalises the level of a photosynthetic pigments and a course of photochemical processes in the chloroplasts of infected leaves, which indicates the protective activity of a drug.

β-1,3-葡聚糖在光合机构和番茄的氧化应激参数的影响（番茄轧机。，CV。塔玛拉）下枯萎叶枯萎人为由真菌病原体引起尖孢镰孢菌。在两个月大的番茄植株中进行了研究。的番茄与病原体的植物感染引起的脂质过氧化（LPO）在叶和显著变化光合装置，其反映在叶绿素（叶绿素）的下降过程激活一个和叶绿素一个/叶绿素b比率和类胡萝卜素含量，扰动PSII中光能的吸收和利用。用β-1,3-葡聚糖预处理植物有助于LPO的稳定化，并使感染叶片的叶绿体中光合色素水平和光化学过程正常化，这表明该药物具有保护作用。
