Abstract

: Raspberry has acquired great interest in human health due to its content of bioactive compounds that provide protection against diseases caused by non-communicable diseases. Bioactive compounds are mainly represented by secondary metabolites such as phenols, anthocyanins, and flavonoids. Biostimulants and elicitors are substances or microorganisms that provide protection and defence to the physiological processes of plants. The present study evaluated the effect of two elicitors (hydrogen peroxide, salicylic acid) and three biostimulants (humic and fulvic acids, glutamic acid, seaweed extracts) on the content of bioactive compounds in raspberry fruits, agronomic and fruit yield parameters in plants. Hydrogen peroxide increased the content of bioactive compounds such as flavonoids, anthocyanins, omega 3 and oleic acid. Salicylic acid increased the content of flavonoids, anthocyanins, and citric acid in raspberry fruits; the number of fruit loaders and fruits per plant was also increased. Humic and fulvic acids, glutamic acid, and glutamic acid combined with seaweed extracts increased the content of flavonoids and anthocyanins, without affecting growth parameters and fruit yield. Glutamic acid and seaweed extracts were the only treatments that increased the content of palmitic acid, while seaweed extracts increased °Brix content in fruits.

诱导子和生物刺激剂对树莓果实中生物活性物质含量的影响

：复盆子因其含有生物活性化合物，可预防非传染性疾病引起的疾病，因此在人类健康中引起了极大的兴趣。生物活性化合物主要表现为次生代谢产物，如酚类、花青素和类黄酮。生物刺激剂和诱导子是为植物的生理过程提供保护和防御的物质或微生物。本研究评估了两种诱导子（过氧化氢、水杨酸）和三种生物刺激剂（腐殖酸和黄腐酸、谷氨酸、海藻提取物）对树莓果实中生物活性化合物含量、植株农艺和产量参数的影响。过氧化氢增加了生物活性化合物的含量，如类黄酮、花青素、ω3和油酸。水杨酸提高了树莓果实中黄酮类、花青素和柠檬酸的含量；果实装载机的数量和单株果实的数量也有所增加。腐殖酸和黄腐酸、谷氨酸和谷氨酸与海藻提取物结合，增加了类黄酮和花青素的含量，而不影响生长参数和果实产量。谷氨酸和海藻提取物是唯一增加棕榈酸含量的处理，而海藻提取物增加了水果中°Brix含量。
