The present study aims to analyze the influence of essential oil crop extracts on seed germination in indeterminate tomato variety Grando F1. The study was conducted during the period 2022-2023 under controlled conditions in a polycarbonate greenhouse at the Department of Plant Production at the Technical University of Varna. Extracts from mint (Mentha piperita), oregano (Origanum vulgare), basil (Ocimum basilicum), thyme (Thymus vulgaris) were used, utilizing different plant parts - leaves, root, stem, and whole plant in various extracting agents. The influence of individual plant parts on seed germination and tomato seedling growth was tracked. The obtained results show that certain extracts, such as those from mint (100% germination) and oregano (100% germination), have a positive impact on germination and accelerate the initial seedling development compared to control plants. Other extracts, such as those from thyme, exhibit an inhibitory effect, delaying emergence and reducing the germination percentage. The study emphasizes the importance of essential oil crops as a source of bioactive substances that can be used to improve agricultural practices in tomato cultivation.
