AB  - Plant protection with natural products is a new trend in environmentally friendly agriculture.
Nepeta rtanjensis Diklić et Milojević is an endemic and critically endangered plant species in Serbia.
We explored the phytotoxic potential of a water emulsion of Nepeta rtanjensis essential oil (NrEO)
with high amounts of trans,cis-nepetalactone on five weeds. The most sensitive was Stellaria media
(L.) Vill., as NrEO (from 0.013% to 0.1%) completely inhibited germination. Germination of
Amaranthus retroflexus L. and Artemisia vulgaris L. was completely inhibited at the highest applied
concentrations of NrEO (0.1%), while Ambrosia artemisiifolia L. germination was reduced to 48% at
the same concentration of NrEO. The most tolerant species was Cephalaria transsylvanica (L.) Schrad.
ex Roem. & Schult. as the final germination rate at the highest applied concentration of NrEO (0.1%)
was 81%, like the control (82%). To our knowledge, this is the first time the interaction of essential oils
on the germination and growth of A. vulgaris and C. transsylvanica is reported. The germination
dynamics of S. media in pots with soil were significantly inhibited when the soil was initially treated
with the highest applied concentration of the NrEO water emulsion (1%). Spraying S. media seedlings
with NrEO significantly inhibited growth parameters (shoot height, shoot fresh weight, and the number
of nodes) at the higher applied concentrations of NrEO (0.5% and 1%). Therefore, the water emulsion
of the essential oil of N. rtanjensis could be potentially developed for use in the control of invasive and
allergenic weeds.

AB  - The use of bioherbicides offers the possibility to suppress harmful weeds by ecologically acceptable methods and thus increase crop productivity. Progress in understanding the mechanisms of bioherbicides action and weed defense response mechanisms, could help in defining
novel weed control strategies. This work highlights the bioherbicide potential of rhizomes of Sorghum halepense L., characterized by a high content of phenolic acids, especially p-hydroxybenzoic
acid (pHB A) and chlorogenic acid (CHL A). Methanol extract of S. halepense rhizome (SHR), and its
major bioactive principles, displayed phytotoxic effects against Chenopodium murale L., which is a
common weed of fields and roadsides. Besides reduction in C. murale seed germination, rhizome
extract of S. halepense applied in the concentrations of 0.01, 0.1, 1 and 2 mg/ml, induced changes
in the activity of antioxidant enzymes in seedlings. Catalase (CAT) activity was increased, while
peroxidase (POX) and superoxide dismutase (SOD) activities were generally decreased, with a few
exceptions (increased POX and SOD activities at 0.1 mg/ml at 0.01 mg/ml SHR, respectively), suggesting that CAT is the major responsible for the elimination of reactive oxygen species generated
during the exposure of C. murale seedlings to SHR. Application of CHL A induced changes in the
activities of antioxidant enzymes, similar to those observed on SHR treatments. The treatment
with pHB A did not significantly change the activity of POX and SOD, while CAT activity was significantly increased at all applied concentrations. These data highlight the phytotoxic potential as
a highly efficient strategy of S. halepense to invade new habitats.

AB  - Nowadays, one of the priorities in agricultural production is the usage of natural bioherbicides
for weed control, instead of commercial herbicides which have a strong negative effect on human
health and the environment. Due to its widespread distribution and the economic losses it causes
to the global economy, Sorghum halepense has been described as one of the world’s most invasive
plant and a dangerous weed. We here examined the possibility to exploit the phytotoxic and bioherbicide potential of this species against other weed species: Amaranthus retroflexus, Chenopodium murale and Datura stramonium. The rhizome extracts of S. halepense (concentration of 0.01,
0.1, 1, 2, and 5 mg/ml) notably reduce the final seed germination of C. murale and D. stramonium,
especially at the highest investigated concentration, while A. retroflexus seed germination was
not affected. Early seedling growth of A. retroflexus was stimulated by the rhizome extract, while in
C. murale and D. stramonium the values of growth parameters were reduced. As revealed by UHPLC/
DAD/qqqMS2
 metabolic profiling of polyphenolics, major bioactive compounds in S. halepense rhizom
extract were phenolic acids: p-hydroxybensoic acid (pHB A), chlorogenic acid (CHL A), and p-coumaric acid (pCUM A). Analysis of bioherbicide potential of these compounds, applied in a series of
concentrations (0.005, 0.01, 0.1, 0.2, and 0.3 mg/ml), revealed that pHB A, CHL A, and pCUM A, are
the main responsible for the overall effects of S. halepense rhizom on selected weeds. These results
highlight Sorghum halepense (L.) rhizomes, and their main constituents, as potent bioherbicides.

AB  - The widespread use of pesticides and their adverse eff ects (through soil pollution, pest resistance, etc.) have created a need for turning to natural resources in search for new/old methods
of pest control. Essential oils belong to a group of volatile secondary metabolites of plants which
aff ect the growth and development of surrounding plants by spreading around in gaseous state.
The eff ect of an essential oil emulsion of Nepeta rtanjensis Diklić et Milojević on seed germination of redroot pigweed (Amaranthus retrofl exus L.) was tested in this experiment. Dynamic and
total germination of seeds were evaluated after fi ve concentrations of the essential oil emulsion
(ranging 0.006-0.1 %) were applied. Before treatment, seeds were stratifi ed for two and a half
weeks at 3±2 °C. The experiment was carried out in Petri dishes under constant temperature of
30±1 °C. Seeds were germinated in the dark over the initial 24 h and then illuminated during 10
min counting sessions at intervals of 1-3 days. Germination of A. retrofl exus seeds was inhibited
after all tested treatments. The fi nal percentage of germinated seeds treated with the lowest
concentration (0.006%) of N. rtanjensis essential oil did not deviate signifi cantly from data in the
control groups but inhibition through germination dynamic was noted. Seeds did not germinate
at all after receiving the highest concentration (0.1%) of the essential oil.

AB  - Allelopathy, the chemical mechanism of plant interference, was detected in many plants from fam. Lamiaceae, including Nepeta species. The majority of Nepeta species are characterized by the presence of ne­petalactone as the dominant component in essential oils. This monoterpenoid lactone exists in the form of one or more stereoisomers, and corresponding enantiomers. The present study investigates the allelopathic potential of Nepeta rtanjensís Diklić & Milojević and Nepeta ca­taria L. essential oils which differ in their qualitative nepetalactone content, on the seed germination of four selected crop species (Lepidium sativum L., Lactuca sativa L. cv. Majska Kraljica, Lotus corniculatus L., cv. Bokor and Brassica napus L. cv. napus). GC-MS analysis revealed that trans,cis- stereoisomer of nepetalactone is dom­inant in essential oil of N. rtanjensis (72,03%). Essential oil of N. cataria used in the present study is character­ized by the high content of cís, trans-nepetalactone (90%). Both essential oils exhibited significant allelopath­ic potential against all model species, with N. rtanjensís essential oil being more efficient. These results sug­gest that nepetalactone stereochemistry significantly determines its allelopathic potential, and that the ef­fect of both nepetalactone stereoisomers is dose-dependent. Essential oils reduced seed germination by in­fluencing germination dynamics, or by irreversibly inhibiting the germination of seeds. Among tested crops, L. sativa was shown to be the most sensitive to allelopathic potential of N. rtanjensis and N. cataria essential oils, while B. napus was the most tolerant.

AB  - The timing and dynamic of seed germination of weed plants and factors affecting them make an important segment of knowledge required for planning weed control in agricultural fields. Environmental conditions existing during seed maturation are the most immediate factor affecting morphological and physiological properties of seeds. We investigated the effect of environmental conditions existing during seed maturation of chickweed (Stellaria media (L.) Vill.), a frequent and widespread weed species, on their germination in the dark and after irradiation. Seeds were sampled from chickweed plants grown inside a glasshouse and those growing wild outdoors in the vicinity of the glasshouse at 3-9 day intervals from mid-February to early June 2007. When fruits were setting in both populations simultaneously, the seeds were collected on the same dates inside and outside the glasshouse. Chickweed plants that grew outdoors began flowering and fruiting more than a month later than those growing in the glasshouse. Plants growing inside the glasshouse stopped fruiting about 20 days after those around the glasshouse. Two months after the last harvest, in August, germinability of the collected seeds was investigated. Despite the different conditions in which seeds had matured, no statistically significant difference was detected in germinability in the dark between the seeds sampled inside and outside the glasshouse, except in two of the 14 pairs of samples collected on the same dates. On the other hand, there were considerable and statistically significant differences in germinability depending on sampling dates. The lowest germination was found in samples collected both inside and outside the glasshouse in late March and early April. Irradiation of imbibing seeds with white daylight stimulated germination of all samples and significantly decreased the differences in germinability of seeds collected on different dates, while not eliminating them fully.
AB  - Poznavanje vremena i dinamike klijanja semena korovskih biljaka i faktora koji na njih utiču je u svetu važan deo korpusa znanja koja su potrebna prilikom planiranja kontrole zakorovljenosti poljoprivrednih površina. Uslovi sredine prisutni tokom sazrevanja semena su prvi faktori koji utiču na kasnije morfološke i fiziološke osobine semena. U ovom radu je ispitivan uticaj uslova sredine tokom sazrevanja semena mišjakinje (Stellaria media (L.) Vill.), česte i široko rasprostranjene korovske vrste, na klijanje u mraku i nakon osvetljavanja. Semena su brana u razmacima od tri do devet dana od sredine februara do početka juna 2007. godine sa biljaka mišjakinje gajenih u staklari i sa biljaka koje su samoniklo rasle oko staklare. U vreme kada su obe populacije plodonosile, semena su brana istog dana i ispred staklare i u staklari. Biljke mišjakinje koje su rasle oko staklare počele su sa sporadičnim cvetanjem oko 15 dana kasnije od biljaka u staklari, ali su, zbog dužeg perioda hladnog vremena koji je usledio, sa masovnijim cvetanjem i plodonošenjem počele više od mesec dana kasnije od biljaka iz staklare. Biljke u staklari su prestale da plodonose dvadesetak dana posle biljaka oko staklare. Dva meseca nakon poslednjeg branja, tokom avgusta, ispitivana je klijavost ubranih semena. I pored različitih uslova u kojima su semena sazrevala nije bilo statistički značajne razlike u klijanju u mraku semena ubranih u staklari i ubranih oko staklare, osim u dva od četrnaest parova uzoraka ubranih istog dana. S druge strane, postojale su velike, statistički značajne razlike u klijavosti u zavisnosti od datuma branja. Najnižu klijavost su imali uzorci semena ubranih krajem marta i početkom aprila i kod semena ubranih u staklari i kod onih ubranih oko staklare. Osvetljavanje imbibovanih semena belom, dnevnom svetlošću, je stimulisalo klijanje svih uzoraka i značajno umanjilo razlike u klijavosti semena ubranih različitih datuma, ali ih nije eliminisalo u potpunosti.
