Так, например, он оказывает стимулирующий эффект на биосинтез фотосинтетических пигментов и фотохимическую активность фотосистемы II хлоропластных мембран, индуцирует накопление фенольных соединений, способствует генерации активных форм кислорода, выполняющих сигнальную функцию и включающих естественные внутренние защитные механизмы, способствует стабилизации уровня окислительных процессов в листьях томата. Установлено, что в производственных условиях препарат «Иммунакт-ГК» по эффективности превосходит отечественный регулятор роста «Экосил», обеспечивая получение прибавки урожая томата до 5 кг/м2.</p></abstract><trans-abstract xml:lang="en"><p>It was shown that the preparation “Immunact-GK” based on β-1,3-glucan exerts a multilateral positive effect on tomato plants grown under conditions of low-volume hydroponics in protected ground. In particular, it has a stimulating effect on the biosynthesis of photosynthetic pigments and the photochemical activity of PS II in chloroplast membranes, induces the accumulation of phenolic compounds, promotes the generation of ROS, which perform a signaling function and start a natural internal defense mechanisms, contributes to stabilize the level of oxidative processes in tomato leaves. It has been established that under manufacturing conditions, the preparation “Immunact-GK” provides an increase in tomato yield up to 5 kg/m2 and exceeds the efficiency of the native growth regulator “Ecosil”.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>β-1</kwd><kwd>3-глюкан</kwd><kwd>«Экосил»</kwd><kwd>хлорофилл</kwd><kwd>каротиноиды</kwd><kwd>фотосистема II</kwd><kwd>перекисное окисление липидов</kwd><kwd>активные формы кислорода</kwd><kwd>томаты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>β-1</kwd><kwd>3-glucan</kwd><kwd>Ecosil</kwd><kwd>chlorophyll</kwd><kwd>carotenoids</kwd><kwd>photosystem 2</kwd><kwd>lipid peroxidation</kwd><kwd>reactive oxygen species</kwd><kwd>tomato</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Препараты нового поколения для защиты растений / Л.
