China Title: The varying promotion effects of fulvic acid with different molecular weights on the enhancement of grain yield and quality of winter wheat Abstract: This study aims to verify the application effect of Fluvic acid (FA) with different molecular weights (MW) on the growth and quality of winter wheat. FA extracted from lignite was divided into 3 MWs (W1≤3000 D, 3000 D<W2≤10000 D, and W3>10000 D) by dialysis, and its structure was analyzed. Three application rates were set for each MW FA in the pot experiment, which were 10, 25 and 50 mg/kg in soil, respectively, and water was the control. There were significant interactive effects of MW and application rates of FAs. Compared with the control, all the FA treatments significantly increased grain yields, nitrogen uptake efficiencies, grain iron concentration, and soil available nitrogen concentration. Heatmap analysis revealed that the W1C2 (10 mg/kg W1) treatment had the most significant impacts for all analyzed indexes, whereas W3C3 (50 mg/kg W3) showed the weakest impacts. The results showed that at a low application rate (10 mg/kg in soil), the promotion effects of the three MW FAs were similar. W1 showed the most significant promotion effects, which was attributed to the combined effects of its lower MW and functional group characteristics.

The different response between potato cultivars was observed after exposure to drought stress (an increase of TCC was in Marabel and Laura cultivars) and after waterlogging stress (in Milva and Marabel cultivars). On average, of all cultivars, both drought and waterlogging stresses caused total carotenoid content to increase with a higher impact of drought stress. In potato tubers, eight carotenoids were identified with the most represented violaxanthin, luteoxanthin, antheroxanthin and lutein. Significant differences in individual carotenoid amounts between cultivars have been determined. On average, drought and waterlogging stresses of all cultivars significantly increased contents of violaxanthin, 9'-(Z)-neoxanthin and luteoxanthin, while antheraxanthin, lutein and zeaxanthin levels decreased. In leaves, both abiotic stresses decreased chlorophyll contents (a, b, a + b) with a very destructive impact of drought stress. While carotenoids accumulated in tubers as a result of stress, the opposite trend was characteristic in leaves, where their content decreased depending on the duration of stress.

Seven crops were tested: lettuce (Lactuca sativa L.) cv. Novosadska majska maslena, oil pumpkin (Cucurbita maxima Duch) cv. Olivija, oilseed rape (Brassica napus L.) cv. NS Ras, pepper (Capsicum annuum L.) cv. Kurtovska kapija, soybean (Glycine max (L.) Merr) cv. ZP Laura, sunflower (Helianthus annuus L.) cv. NS Kruna, and tomato (Solanum lycopersicum L.) cv. Dunavski Rubin. Herbicide dicamba in the range of 0.14 to 1 155.6 g a.i. (active ingredient)/ha inhibited biomass, height, leaf area, and visual injury of all crops, while glyphosate doses from 0.48 to 3 840 g a.i./ha also reduced the growth of all tested species. A rate of 116 g a.i./ha mesotrione was needed to reach 80% visual injury in oilseed rape, while the same effects on lettuce only required 1.8 g a.i./ha of mesotrione. Tomato and oil pumpkin were also sensitive to low mesotrione doses, where only 1.3 g and 0.5 g a.i./ha of mesotrione was needed for 80% of biomass reduction, respectively. Lettuce was the most sensitive crop of all tested species; biomass was reduced by 80% by dicamba, glyphosate, mesotrione, and nicosulfuron at the low rates of 33 g a.i./ha, 19 g a.i./ha, 1.25 g a.i./ha, and 2.7 g a.i./ha, respectively. Among all herbicides, visible injuries were detected in dicamba at the lowest rates. Soybean was the most tolerant of glyphosate, mesotrione, and nicosulfuron. Based on the available literature and obtained results, herbicide off-target movement must be mitigated to maximise herbicide efficacy and decrease the negative influence on susceptible plants and the environment.

In this study, heavy metal content is present in commonly consumed leafy plants (Atriplex hortensis, Spinacia oleracea, Urtica dioica, Beta vulgaris, and Brassica oleracea) from the mining area near Tuzla in Bosnia and Herzegovina was determined. After the preparation of the samples by wet digestion with HNO3, the flame and graphite furnace atomic absorption spectrometry was used. According to the results, the lowest concentration in leafy plants was obtained for Cr 0.08 mg/kg (Brassica oleracea) and the highest for Fe 539.15 mg/kg (Spinacia oleracea). The novelty of this study was to estimate health risk assessment for selected leafy plants. The estimated daily intake (EDI) of Pb, Mn, Zn, and Cd from consuming leafy plants was higher than the maximum tolerated daily intake. For adults, the total target hazard quotient (THQ) calculated based on EDI of the heavy metals was found to be > 1 for Pb and Cd due to all leafy plant consumption and for the children risk level of THQ was observed for most heavy metals. The hazard index due to the intake of toxic metals from ingesting leafy plants was much > 1. According to the total carcinogenic risk index for adults and children, the carcinogenic risks for all samples were higher than the tolerable range. Based on the results of this study, there is a significant non-carcinogenic and carcinogenic health risk to the population associated with the consumption of leafy plants cultivated in the mining area.

A sunflower genotype was randomly planted in a complete block design with eight different combinations of irrigation (T1-T8) by increasing the available soil moisture measured at different plant growth stages (vegetative, flowering and grain formation). Results indicated that the total phenolics of extracts varied between 1.03-2.03 times more than under drought stress (T8). The antioxidant capacity response of seed cake was 14-39% lower than under drought stress. Irrigation treatment, except in the grain formation stage, was found to enhance the biosynthesis of phenolic compounds such as vanillic and caffeic acids. Irrigation only in the grain formation stage induced the accumulation of phenolic compounds such as coumaric acid and rutin hydrate. The present study established that residues resulting from oil extraction could be converted to a polyphenol-enrichment agent for food systems by manipulating the irrigation treatments.

This task is more difficult to perform in high-mountainous landscapes, at an altitude of more than 4 000 m a.s.l. Moreover, these high-mountain ecosystems are the most vulnerable to various kinds of anthropogenic impacts, and therefore the relevance of bioremediation is obvious. The research was conducted in the high-altitude ecosystems of the Kyrgyz Republic at the Kumtor mine. In this study was carried out on the bioremediation of oil contaminated soil using biostimulation, bioaugmentation and biostimulation + bioaugmentation remediation techniques for 90 days in the climatic conditions of high mountain region. The biostimulation treatment showed the highest total petroleum hydrocarbons (TPH) biodegradation percentage 62.78% compared to the bioaugmentation 50.63% and biostimulation + bioaugmentation 49.11%. Thus, the method of biostimulation proved to be the most effective method for bioremediation of soils contaminated with petroleum products. The application of this method could be one of the successful methods of recycling contaminated soils. This study demonstrated the possibility of restoring TPH-polluted soils using biological methods of soil treatment in climatic cold conditions of high mountains.
