Проучване на алелопатичен ефект на извлеци от етеричномаслени растения върху кълняемостта при краставица
Павлина Наскова, Пламена Янкова
Резюме: Изследването е проведено през периода 2022-2023 година при контролирани условия в оранжерията на катедра „Растениевъдство“ на Технически университет – Варна. Засяти и отгледани са следните етеричномаслени растения: кориандър, мента, риган и босилек, от които са получени филтрати. Целта на проучването е да се проследи и анализира влиянието на алелохимикали върху кълняемостта на семената на краставица, чрез тестване на следните растителни екстракти получени от декокт, тинктура, маслен филтрат, медицинско вино и оцет.
Различните части на растенията влияят по различен начин върху кълняемостта на семената от краставици. Най-висок процент (100%) на покълване на семената се регистрира при растението риган във всички варианти на растителни извлеци, следван от кориандър (при медицински оцет) и босилек (при медицинско вино). При другите извлеци най-силно влияние върху процента на кълняемост оказват отделните части на растението самостоятелно или в комбинации с листа, стъбла и корен.
