Study of the allelopathic effect of essential oil plant extracts on cucumber germination
Pavlina Naskova, Plamena Yankova
Abstract: The study was carried out in 2022-2023 under controlled conditions in the greenhouse of the Department of Plant Breeding, Technical University - Varna. Coriander, mint, oregano and basil, from which filtrates were obtained. The aim of the study was to monitor and analyse the effect of allelochemicals on the germination of cucumber seeds by testing the following plant extracts obtained from decoction, tincture, oil filtrate, medicinal wine and vinegar.
Different parts of the plants have different effects on the germination of cucumber seeds. The highest percentage (100%) of seed germination was recorded for oregano plant in all variants of plant extracts, followed by coriander (in medicinal vinegar) and basil (in medicinal wine). For the other extracts, the strongest influence on germination rates is exerted by the individual parts of the plant alone or in combination with leaves, stems and roots.
