Abstract

Nicanje sjemena u poljskim uvjetima je pod utjecajem velikog broja čimbenika.
Promjenjivost njihova utjecaja na nicanje sjemena ovisi prije svega o dubini na kojoj se sjeme
nalazi u tlu. Europski mračnjak (Abutilon theophrasti Med.) zbog svojih značajki i prilagodbi
na okolišne uvjete, možemo naći i na većim dubinama u tlu zbog čega je njegovo suzbijanje
otežano. Cilj ovog rada bio je utvrđivanje nicanja tretiranog (skarificiranog) i netretiranog
(naturalnog) sjemena mračnjaka tijekom dvije godine istraživanja u poljskim uvjetima na
različitim dubinama sjetve (3, 6 i 9 cm). Rezultati istraživanja pokazuju da i dubina i tretman
značajno utječu na nicanje sjemena mračnjaka, ali i da se ukupno nicanje značajno razlikuje
po istraživanim godinama. Ukupno nicanje proporcionalno opada s porastom dubine dok
učinak tretmana na nicanje ovisi o pedoklimatskim uvjetima tijekom godine.

Abstract (english)

Seed germination is influenced by numerous environmental factors in the field
conditions. Variability of their influence on final germination depends mostly on seed depth.
Due to its characteristics, velvetleaf can germinate even in greater seed depths, which causes
difficulties in their control. The aim of this study was monitoring scarified and non-scarified
velvetleaf seeds in field conditions on different seed depths (3, 6 and 9 cm) during 2 years of
research. Results indicate that even seed depth and treatment can significantly influence
velvetleaf seed germination, more so cumulative velvetleaf germination differ significantly
between years. Cumulative germination decreases proportionally with depth, while effect of
treatment depends on agricultural conditions during the year.
