AB  - Reproductive traits of alien plant species represent as important traits involved in their invasive success. Fecundity presents a biological mechanism that ensures survival in fickle and
unfavourable environmental conditions and enables efficient expansion in new areas. In many
European countries, Ambrosia artemisiifolia L. (AMBEL). is characterized as an invasive weed
species with a large seed production, which retains germination for many years. Unlike AMBEL, Ambrosia trifida L. (AMBTR) is less widespread and investigated, but its biological and
ecological properties attract the attention of many scientists. Both species are strong competitors for natural resources and space and very often in the ecosystem influence on the
repression of other plant species, and changing structures of plant communities. Although
the spread of AMBTR observed in recent years, it has not yet become the dominant species
in comparison to AMBEL. The aim of the research was to examine the generative production
of AMBEL and AMBTR in co-association and does it this competition could restrict the spread
rate. Field experiments were carried out at a farm near Dobrić, Republic of Serbia (44°41´N,
19°34´E) using a replacement design model, where the competitive interaction between AMBEL and AMBTR was assessed. The experiment involves treatments were the proportion of
AMBEL to AMBTR of 10:0; 8:2; 4:6; 6:4; 2:8 and 0:10), and 10 plants per m2 arranged in a
randomized block design (four replication). During the two different climatic conditions year,
seed production of AMBTR and AMBEL were measured in 2016 and 2017. Data analysis were
performed in R-studio. During two seasons, AMBEL produced more seeds than AMBTR, with
no significant statistical differences between treatments. Although AMBTR achieved higher
seed production in a more favourable climate year (2017), in both seasons, the highest numbers of seeds were achieved in treatments with its highest number/m2
 in relation to AMBEL.
Interspecific competition reduced seed production of AMBTR, while intraspecific competition
did the opposite. Analysis of variance showed statistically significant differences between treatments. Unlike AMBTR, the obtained results could indicate the more successful invasiveness
of AMBEL, since in unfavourable environmental conditions (reduced living space and stressful
climatic conditions) it produces richer offspring, which is a precondition for its further spread
and colonization to new habitats.

AB  - Plantažno gajenje lekovitog bilja je u ekspanziji, a s obzirom na to da suzbijanje korova predstavlja najveći izazov u ovoj proizvodnji, cilj rada je bio ispitivanje mogućnosti njihovog suzbijanja malčiranjem. Osim toga, u istraživanje je bio uključen i herbicid metamitron čija je primena u ovakvim usevima prihvatljiva u nekim zemljama. Kao eksperimentalni usev izabran je usev angelike (A. archangelica L.) čije etarsko ulje iz korena je jedno od najcenjenijih na tržištu, pa se može očekivati povećanje proizvodnih površina. Ogled je postavljen kao potpuno slučajan blok sistem u četiri ponavljanja i to u pet tretmana: agrotekstilna vodopropusna folija, piljevina, herbicid metamitron, kontrola bez korova (pozitivna) i kontrola sa korovima (negativna). Najveća zakorovljenost zabeležena je u negativnoj kontroli i u tretmanu sa primenom herbicida metamitron. Malč od piljevine rezultirao je smanjenjem zakorovljenosti u odnosu na prethodna dva tretmana. Agrotekstilna folija i redovno plevljena kontrola su bile bez prisustva korova. Dakle, najbolja efikasnost u suzbijanju korova postignuta je primenom agrotekstilne malč folije, koja je u potpunosti sprečila nicanje korova (efikasnost 100%). Znatno slabiji efekat je ostvaren primenom piljevine (efikasnost 51,28%), dok je metamitron svežu biomasu korova redukovao za samo 26,71%. Dobijeni rezultati pokazuju da je malčiranje kao fizička metoda suzbijanja korova u usevu angelike podesnije u poređenju sa primenom herbicida metamitron ukoliko u usevu dominiraju travne vrste, koje nisu u spektru delovanja ovog herbicida. Značaj ovih rezultata je utoliko veći što u našoj zemlji metamitron, kao ni drugi herbicidi, nije registrovan za primenu u lekovitom bilju.
