“…These results may be due to the superior effect of both eucalyptus oil and Trichoderma harzianum, which has resulted in increased cabbage and cauliflower vegetative growth characteristics (Table 2 and 3). These results agree with those of Niakan and Saberi (2009), also Cumagun (2012), Rehman et al (2012), and Hassannejad & Ghafarbi (2013).…”

“…6(B)). It is a known fact that antioxidant enzyme production is increased in order to eliminate the reactive oxygen species caused by biotic and abiotic stress in plants [45][46][47]. Allelochemicals which cause an increase in enzyme activity at low concentrations, can negatively affect enxyme activity at high concentrations.…”

In this study, we aimed to investigate the allelopathic effects of sunflower and wheat root exudates on the common weeds such as wild mustard and white mustard in our region. The root exudates which were obtained by soaking 8 weeks old sunflower and wheat seedlings (20 or 40 seedlings) in 100 mL of distilled water for 3 days were applied to the leaves of wild mustard and white mustard. In order to compare the allelopathic effect, the recommended dose (1 g.da -1 ) and twice the recommended dose (2 g.da -1 ) of Gromstor (Tribenuron-methyl), a herbicide preferred by farmers for the chemical control of these weeds was also applied. The allelopathy was performed for wild mustard and white mustard seedlings by the measurement of different physiological and biochemical parameters, such as chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, proline, total protein amounts and superoxide dismutase enzyme activity. The amounts of total chl and carotenoid in wild mustard leaves decreased in all treatment groups compared to control. The highest decrease in total chl (50.93%) and carotenoid (46.69%) was oberved in the treatment of 40 wheat seedlings. 100 mL -1 distilled water. In the white mustard leaves, the amount of total chl in all treatment groups except the treatment group of Gromstor 2 g.da -1 and carotenoid in all treatment groups increased compared to the control. The highest increases again were observed in 40 wheat seedlings. 100 mL -1 distilled water treatment. The proline amounts in wild mustard and white mustard increased in all treatment groups. The highest increase was observed for the treatment of 20 wheat seedlings. 100 mL -1 distilled water in wild mustard (459.69%) and 40 sunflower seedlings. 100 mL -1 distilled water in white mustard plant (104.70%). In superoxide dismutase enzyme activities, treatments decreased activity except treatment of 40 sunflower seedling root exudate in wild mustard, while increased activity outside commercial herbicide treatment in white mustard. The results showed that sunflower and wheat root exudates have allelopathic effects on wild mustard and white mustard weeds. It is thought that the study will be a reference for new studies that will enable the use of plant root exudates as bioherbicides or foliar fertilizers and will contribute to the fight against weeds in organic agriculture. Materials and Methods MaterialsThe wild mustard (Sinapis arvensis L.) seeds collected from the fields in Imamoglu district of Adana province were assessed according to the Flora of Turkey and the East Aegean Islands [16]. The white mustard (Sinapis alba L.) seeds were purchased from Mersin Kemal Cuce Tarim Transport Food Construction Trade Industry Limited Company. The seeds of Sems sunflower (Helianthus annuus L.) and Sarıbasak wheat (Triticum aestivum L.) were obtained from the Eastern Mediterranean Agricultural Research Institute. All chemicals used in the study were purchased from Sigma-Aldrich and Merck companies. Obtaining the Root ExudatesThe sunflower and wheat root exudates were...

“…Previous researches showed that the Eucalyptus can break the soil water balance and reduce the soil fertility, which lead to decrease the biomass of undergrowth vegetation and simplify the community structure, ultimately resulting in biodiversity reduction and causing soil erosion (Florence, 1986;Guo, 2007). Further studies showed that allelopathic effect caused by secondary metabolism substance, so called allelochemicals, which were released from decomposing leaf litter of Eucalyptus in different ways was the main reason for these ecological problems (Niakan & Saberi, 2009;Zhang & Fu, 2009).…”

In order to investigate the effect of decomposing leaf litter of Eucalyptus grandis (E. grandis) on the growth trait and resistance physiology of Eremochloa ophiuroides (E. ophiuroides), three treatments with different amounts of leaf litter were designed in this study, including A1 (30 g/pot), A2 (60 g/pot), A3 (90 g/pot), and a group without treatment (0 g/pot, CK), The blank experiment group with distilled fallen leaves were set as mentioned above. The results showed that growth traits (root length, plant height, fresh weight and dry weight) were significantly inhibited along with the increasing amounts of E. grandis leaf litter. The activity of CAT and SOD increased at low content of leaf litter and less processing time, but significantly dropped over time. The activity of POD was inhibited at all tested time, and all treatments were significantly lower than that in CK. The MDA content of CK was similar to that in A1 and A2, but significantly lower than that in A3 at the 30 th day after sowing, and three treatments were significantly higher than that in CK after sowing for 60 days and 90 days. The soluble sugar content went up with the increase of leaf litter content at all time points, while the change of soluble protein contents was opposite. This study demonstrated that the decomposing leaf litter of E. grandis had obviously allelopathic effect on the growth and resistance physiology characteristics of E. ophiuroides, which should be controlled rationally in the E. grandis plantation.
