Uticaj biopreparata na energiju klijanja, ukupnu klijavost i zaštitu semena mirođije

Abstract

Mirođija (Anethum graveolens L.) je jednogodišnja začinska i lekovita biljka iz familije Apiaceae. Visoka energija klijanja i procenat klijavosti su potrebni za postizanje visokog prinosa. Cilj ovog istraživanja je bio utvrđivanje najefikasnijeg biopreparata sa blagotvornim dejstvom na energiju klijanja, ukupnu klijavost i zdravstveno stanje semena mirođije. Ispitivanja su sprovedena sa dva sredstva za zaštitu bilja, dozvoljena u organskoj proizvodnji (‟Extrasol F” i ‟Polyversum”) i tri biljna preparata (‟Fermentisani ekstrakt hajdučke trave”, ‟Fermentisani ekstrakt čička” i ‟Fermentisana mešavina LAB mix”). Klijavost semena je povećana u svim tretmanima u odnosu na kontrolu. Tretmani preparatom ‟Fermentisana mešavina LAB mix” ispoljili su najveći uticaj na energiju klijanja i ukupnu klijavost semena. Na osnovu simptoma i znakova bolesti, prisustvo Alternaria sp. je potvrđeno na površini semena mirođije. U poređenju sa kontrolom, zaraza semena je smanjena u tretmanima sa preparatima ‟Fermentisana mešavina LAB mix” i ‟Fermentisani ekstrakt čička”.

Dill (Anethum graveolens L.) is an annual herb and medicinal plant from the Apiaceae family. High energy germination and germination percentage are required to achieve high yield. The aim of the study was to discover the most efficient biopreparations with a beneficial effect on dill seed energy germination, total germination and seed health. Testing was conducted with two plant protection products, permitted in organic production (‟Extrasol F” and ‟Polyversum”), and three herbal preparations (‟Fermented extract of yarrow”, ‟Fermented burdock extract” and ‟Fermented LAB mix”). The seed germination was increased in all treatments, in comparison to control. The treatments with the preparation ‟Fermented LAB mix” manifested the greatest influence on energy germination and total seed germination. Based on the symptoms and signs of the disease, the presence of Alternaria sp. was confirmed on the surface of dill seeds. The seed infection was reduced in treatments with ‟Fermented LAB mix” and ‟Fermented Burdock Extract” compared to the control treatment.
