Their application is not only economically profitable, but also improves the action of the fertilizers and increases the yields. The study aims to investigate the effect of some foliar fertilizers and biostimulators on the elements of productivity, seed yield and the essential oil content and composition of Lozen 1 coriander (Coriandrum sativum L.) cultivar. The field trial was carried out on leached Smolnitsa soil type in the region of the village of Zhrebino, South-Eastern Bulgaria in the period 2018-2020. The experiment was arranged according to the randomized complete block design in four replications with a plot size of 15 m2, after predecessor wheat. The treatment of coriander with the leaf fertilizer Masterblend in a dose of 2.5 kg ha1 resulted in an average yield increase of 11.8% compared with the untreated control. After treatment with the foliar applied products an increase in the essential oil content from 2.9% to 9.6% was established, as the highest values were obtained when using the biostimulator Fertigrain - 1.26% and the foliar fertilizer Masterblend - 1.25%. The most frequent components of the essential oil were linalool, gamma-terpinene, alpha-pinene and camphor. The highest values of linalool were observed after the application of the products Masterblend and Poly Plant. The used products stimulated the biological potential of the tested cultivar and could be recommended for further investigations by other essential oil crops.

Leaves using microwave-induced hydrodistillation and simultaneous extraction (MHDE). In this process, we realize the rotation of the material through a rotary motor so that the material is uniformly irradiated by microwaves. The influencing factors on MHDE were systematically optimized by single factor and central composite design. Under the obtained optimization conditions, the yields of essential oil, rosmarinic acid, and polysaccharides were 0.64% +/- 0.03%, 0.18% +/- 0.01%, and 4.35% +/- 0.19%, respectively. GC-MS analysis results showed that the main component of essential oil prepared by MHDE was perillaldehyde, which accounted for 51.91% of the total essential oil, followed by caryophyllene, accounting for 15.79%. However, the ratio of perillaldehyde in the essential oil obtained by traditional hydro distillation and extraction (HDE) was only 40.69%, and the proportion of caryophyllene was only 12.50%. MHDE uses sucrose stearate with a long hydrocarbon chain structure as an additive, which reduces the nonterpene aliphatics in the obtained essential oil.

    查看更多>>摘要：In the present study, an integrated process involving hydrothermal pretreatment (HP) and acid hydrotropic pretreatment (AHP) was proposed for co-producing high value-added xylooligosaccharides (XOS), fermentable sugars, and lignin nanoparticles (LNPs) from poplar (Populus spp.). Approximately 36.2% of XOS (X2-X6) was obtained from raw xylan after HP at 170 degrees C for 50 min. Moreover, LNPs with an average size of 44.8 nm were produced from the HP-AHP pretreated poplar, using p-toluenesulfonic acid at a concentration of 55% (w/v) at 90 degrees C for 120 min. A mild alkaline incubation adopted to reduce the surface lignin of HP-AHP pretreated poplar significantly improved the enzymatic hydrolysis yield from 69.2% to 97.3%. The mass balance results showed that 1000 g of poplar generated 66.4 g of XOS, 468.0 g of fermentable sugars (442.0 g of glucose and 26.0 g of xylose), and 103.5 g of LNPs.

    查看更多>>摘要：Use of green alternative sources for energy like biofuels is one of the most important requirements of sustainable development. This research aims to design and prepare a new magnetically recoverable catalyst based on agrowastes. For this purpose, cotton waste was selected and its application in the preparation of magnetic catalysts (Cotton/Fe3O4@SiO2@ H3PW12O40) used for the production of biodiesel, which is based on heteropoly acid (HPA), was investigated. Magnetic cotton powder with high dispersibility, porosity, and magnetism were prepared by the co-precipitation method and covered by silica using tetraethyl orthosilicate (TEOS) to form Cotton/Fe3O4 @SiO2. Finally, the nanostructured catalyst was prepared by impregnation of phosphotungstic acid (HPW). The proposed catalyst was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FESEM) equipped with Dispersive Energy X-ray spectroscopy (EDS), Thermo gravimetric analysis (TGA), The Brunauer-Emmett-Teller (BET) surface area analysis, Barrett-Joyner-Halenda (BJH) pore size and volume analysis and vibrating sample magnetometer (VSM). The performance of the proposed core-shell nanocomposite to catalyze transesterification reaction was evaluated and optimized by response surface methodology (RSM). The optimum conditions were found as 3 wt%, 3.5 h, 12:1, and 70 degrees C, for catalyst dosage, reaction time, the molar ratio of methanol to oil, and reaction temperature, respectively. The production yield was higher than 90% for three runs. On the fourth attempt, the catalyst performance was decreased slightly to 85.5%. The used catalyst was characterized by FT-IR, XRD, EDS, and FESEM for leaching studies. The quality of the biodiesel product was tested according to the standard procedures defined by the American Society for Testing and Materials (ASTM) and European Union (EU).

Due to the domestication and introduction of Satureja mutica cultivars, for the first time and the lack of comprehensive research on its cultivation, the need for research on the nutritional needs of this plant and the introduction of suitable fertilizer treatments that can be used by farmers is important. This experiment was carried out in 2018 and 2019 in field conditions using randomized complete blocks with three replications and 21 treatments in the Research Institute of Forests and Rangelands. The results of mean comparisons of fertilizer treatments (mean of two years) showed that the highest plant height, with 88 and 80 cm, was related to cow manure treatments of 30 and 60 tons per hectare, respectively. The highest flowering shoot yield, with 4427, 4266, and 4113 kg ha(-1), was obtained from N(50)P(2)5K(25) + vermicompost10 and N(50)P(2)5K(25) + cow manure(60) and N(50)P(2)5K(25) + cow manure(30) treatments in the second year, respectively. The lowest yield of the flowering shoot (849 kg ha(-1)) belonged to Pseudomonas putida treatment. The highest leaf yield, with 2556 and 2441 kg ha(-1), was obtained from N(50)P(2)5K(25) + vermicompost10 and N-25, P-25, K-25 + cow manure(60) treatments, respectively. According to the results, the highest nitrogen content, with 2.44 and 2.32 g/100 g, was obtained from the cow manure(30) treatment in the first and second year, respectively. The maximum nitrogen uptake with 94.43 kg ha(-1) was obtained from N-50, P-25, K-25 + vermicompost10. The lowest nitrogen uptake at 24 kg ha(-1) was related to Pseudomonas putida treatment. The mean comparison of two years showed that the highest essential oil percentage (2.11 g/100 g) and yield (79.27 kg ha(-1)) were obtained from the second year compared with the first year. Carvacrol, gamma-terpinene, thymol, and p-cymene were the major components in the essential oil. The results showed that the combined treatments of chemical fertilizers with animal manure and vermicompost are suitable treatments to increase the yield of different organs and essential oil yield in field conditions.

    查看更多>>摘要：The aim of this study was to investigate the content of phenolics, free amino acids, tocopherols, tocotrienols and in vitro biological activities (alpha-amylase, alpha-glucosidase, and pancreatic lipase inhibition activity) of 12 cultivars of Chaenomeles x superba, japonica and speciosa leaves. In the present work 39 phenolic compounds were tentatively identified, including polymeric procyanidins > flavan-3-ols > phenolic acids > flavonols > flavanones > flavones > ellagitannins. Chaenomeles leaves contained on average 16.8 g of phenolics per 100 g dr y weight (dw), with C. x superba & PRIME;Nicoline & PRIME; displaying the highest (27.5 g/100 g dw), and C. x superba & PRIME;Colou r Trail & PRIME; the lowest (7.7 g/ 100 g dw) total phenolic content. Chaenomeles leaves possess a l l eight tocol analogs (fou r tocopherols (TP), and four tocotrienols (TT)), ranked in decreasing content: alpha-TP > beta-TP > gamma-T P > delta-TP > alpha-TT > beta-TT > delta-TT > gamma-TT. The most active form (alpha-tocopherol) was present in amounts from 480.6 to 7201.1 mu g/100 g dw. 23 amino acids were identified, including a l l nine essential amino acids. The highest amount of O-phospho-L-serine was found (average 249.2 mg/100 g dw). Leaves of C. japonica & PRIME;Red Joy & PRIME; displayed the highest total amino acid content (2735.2 mg/100 g dw). Chaenomeles leaves showed alpha-amylase (8.2-24.5 mg/mL), alpha-glucosidase (1.2-6.3 mg/mL), and pancreatic lipase (7.0-10.5 mg/mL) inhibition activity (expressed as ha l f maximal inhibitor y concen-tration, IC50). Chaenomeles leaves can be a good material for obtaining extracts rich in phenolics, vitamin E or amino acids, providing an alternative, natural source of these compounds to help meet the growing demand for nutraceuticals and supplements.

    查看更多>>摘要：Increasing demand for wood in the particleboard industry, its associated cost, and the potential health issues with chemical resins have led to a search for using environment friendly renewable agricultural products to replace the wood particles. The objective of this study was to evaluate the properties of particleboards manufactured from renewable products such as wheat straw and the high fiber fraction of distillers dried grains with solubles (DDGS). The high fiber fraction of the DDGS was obtained by sieving and aspiration to get two fractions -one with high protein and another with high neutral detergent fiber (NDF) content compared with the original DDGS. The number 20 sieved and aspirated lighter fraction (SA#20-L) had the highest NDF content at 25.44% higher than the original DDGS. Therefore, this SA#20-L fraction was selected for particleboard manufacturing. Particle size distribution (PSD) was analyzed using n-ary sumation Volume machine vision approach to study the effect of particle morphology and size on properties of boards. Low-density particleboards were made from SA#20-L DDGS and wheat straw at three different loadings of DDGS (25%, 50%, and 75%) using 3% (dry basis) phenol formaldehyde (PF) resin. Particleboards with the same the DDGS loading and processing conditions were also manufactured from original DDGS to test the effectiveness of using the high fiber DDGS for manufacturing particleboards. The inclusion of DDGS (both SA#20-L and original) at 25% loading in the wheat straw boards had comparable mechanical properties to control wheat straw particleboards. With the inclusion of even higher DDGS loading (50% and 75%), physical properties were significantly improved as compared to control, but mechanical properties declined. Modulus of Elasticity (MOE) was superior for high fiber DDGS than particleboards made from the original DDGS. Other mechanical properties, however, were better for the original DDGS. At 25% DDGS loading, both SA#20-L and original DDGS met the ANSI 208.1 standard for MOE, modulus of rupture, and internal bond values for low-density particleboards.

    查看更多>>摘要：Nasonovia ribisnigri Mosley (Hemiptera: Aphididae) is the most damaging aphid species of lettuce grown in open fields. Populations of N. ribisnigri are developing resistance to insecticides, making their control difficult. Botanicals are an alternative for pest control. Aniseed (Pimpinella anisum L.) is a relevant crop in the production of essential oils. The effect of aqueous nano-formulations of this oil and its main compound (E)-anethole were tested against N. ribisnigri in a growth chamber, a greenhouse (in spring for two years, 2019 and 2020) and in the open field in a plot in the Southeast of Spain (Torrepacheco, Murcia) in May 2019. Aniseed essential oil nanoemulsions were prepared using a laboratory dispersing machine at a high-speed regime (10 min, 7940 revs/min, 15 degrees C) using Tween80 as a surfactant at a 1:2 ratio. Foliar applications of aniseed essential oil at concentrations of 0.2% and 0.4% (0.1 and 0.2 mL respectively) to lettuce plants infested with homogeneous populations of N. ribisnigri reduced the number of insects compared with the control in the laboratory (efficacies > 50%) and greenhouse (efficacies > 25%, 48 h after treatment) experiments. During the field trial, a reduction in the aphid populations was also produced after the application of the products, without any phytotoxic effects observed on the crop. Likewise, (E)-anethole gave similar results as aniseed essential oil (with efficiencies of up to 47% with respect to the control) without damaging the plant.

    查看更多>>摘要：The design of functional polyamides for specialized applications has attracted increasing attention during recent years. Herein, a facile and efficient method towards mechanical strong functional polyamides with varied side groups is developed. An alpha,omega-diene functional amide monomer was prepared through the amidation reaction of methyl 10-undecenoate (a kind of castor oil derivative) and 1,3-diamino-2-propanol. The pendant hydroxyl group was converted to ester groups to afford six other monomers. High molecular weight functional polyamides with varied pendant groups, including hydroxyl, acetate, butyrate, isobutyrate, benzoate, acrylate, and imidazole, were prepared via thiol-ene addition polymerization. Differential scanning calorimetry (DSC) and atomic force microscopy (AFM) results indicate that the melting temperature, degree of crystallization, and crystalline size depend on the pendant groups. Inspired by natural silk proteins, functional polyamides with controllable mechanical properties can be achieved by copolymerizing of these monomers.

    查看更多>>摘要：Carbon dots (CD) were developed via hydrothermal synthesis using potato peel as functional fillers for food packaging films. The CD showed strong antioxidant and antimicrobial activity with low cytotoxicity as more than 80% of mouse fibroblast L929 cells survived even when exposed to 500 mu g/mL for 72 h. The CD was used as a functional filler for preparing a gelatin-based functional film, and it was uniformly dispersed in biopolymer, indicating a compatible packaging film. The FTIR result showed no change in the chemical structure, but an H-bond was apparent between the CD and gelatin. The addition of CD produced a highly transparent film with significant improvement in the water vapor permeability (by 28%) and hydrophobicity (by 9% and 13%) properties of the gelatin film without much changing of the mechanical properties. The CD-added gelatin films indicated UV-barrier property and strong antioxidant activity. Moreover, the antibacterial efficacy increased significantly. Therefore, the CD-added gelatin films have great potential as a value-added, low-cost, safe, and functional nanofiller for the preparation of packaging applications.
