Defense response of strawberry plants against Botrytis cinerea influenced by coriander extract and essential oil

Abstract

Essential oils and extracts are investigated in sustainable plant protection area lately. Alternative antifungal substances are especially relevant for major economic-relevance pathogens, like Botrytis cinerea (causal agent of strawberry grey mold), control. However, the reaction of plants to alternative protection with plant-origin products is currently unknown. Induced stress in plants causes changes in antioxidant and photosynthetic systems. The aim of the research was to determine the defense response of strawberry plants under application of coriander seed products. In the first step of the research, we determined coriander seed (Coriandrum sativum), black seed (Nigella sativa) and peppermint leaf (Menta × piperita) products’ antifungal activity against B. cinerea in vitro. Secondly, we continued evaluation of antifungal activity under controlled environment on strawberry plants of the most effective coriander seed products. Additionally, we evaluated the antioxidant and photosynthetic parameters in strawberries, to examine the response of plants. Antifungal activity on strawberries was determined based on grey mold incidence and severity after application of coriander products. Impact on photosynthetic system was examined measuring photosynthetic rate, transpiration rate, stomatal conductance, and intercellular to ambient CO2 concentration. Strawberry leaves were collected at the end of the experiment to analyze the antioxidant response. The highest antifungal activity both in vitro and on strawberries had coriander seed essential oil, which decreased grey mold severity. Coriander extract increased the photosynthetic capacity and antioxidant response of strawberry plants, however had negative effect on suppression of grey mold. In most cases, the essential oil activated antioxidant response of strawberry plants lower than extract. Our study results provide no direct impact of increased photosynthetic capacity values and antifungal effect after treatment with natural oils. The highest concentrations of coriander essential oil and extract potentially demonstrated a phytotoxic effect.

Initial Physiological, Biochemical and Elemental Garlic (Allium sativum L.) Clove Responses to T. vulgaris and S. aromaticum Extract Application

“…There are studies indicating plant extracts' impact on antioxidant activity and compounds in plants and fruits. Coriander seed essential oil and extract decreased DPPH, ABTS antioxidant activity and total phenolic compounds in inoculated strawberry leaves, but only with lower applied concentrations [41]. A dose-dependent effect was observed with Lawsonia inermis L. extract, which increased wheat shoot and root system growth and accumulated 90% more total phenolic compounds in wheat compared to untreated plants [42].…”

Overview of the control of plant fungal pathogens by natural products derived from medicinal plants

“…Research has shown that the enzyme activity of watermelon plants PPO and SOD increased observably after treating the extraction of S. aromaticum, Stellera chamaejasme, and Glycyrrhiza uralensis (Zhang 2019). In addition, induced stress in plants causes changes in antioxidant and photosynthetic systems, Dėnė et al (2023) found that Coriandrum sativum could increase the photosynthetic capacity and antioxidant response of strawberry plants; however, it had a negative effect on the suppression of strawberry grey mould.…”

Green Synthesis of Silver Nanoparticles with Hyssopus officinalis and Salvia officinalis Extracts, Their Properties, and Antifungal Activity on Fusarium spp.

“…Many of these phytochemicals have beneficial effects on human health as well, effectively treating various diseases [ 10 ]. Additionally, extracts obtained from a broad spectrum of plants were proven to have inhibitory effects against horticultural fungal pathogens in vitro [ 11 , 12 , 13 , 14 ]. For example, different extracts of Hyssopus officinalis L. and Salvia officinalis L. were shown to be rich in bioactive compounds, which contribute to the anti-fungal effect [ 15 , 16 , 17 , 18 ].…”
