Olive productivity should be improved through stimulating nutrition,particularly under poor fertility soils.Consequently,the objective of this study was to assess the efficacy of applying organic and bio-fertilizers on the physiological growth,yield and fruit quality of olive trees under newly reclaimed poor-fertility sandy soil in an arid environment.During a field experiment carried out at El-Qantara,North Sinai,Egypt over two consecutive seasons(2019-2020 and 2020-2021),olive Kalamata trees were evaluated under three organic fertilizer treatments alone or in combination with three bio-fertilizers treatments.Organic fertilizer was applied as goat manure(16.8 kg/tree/year),or olive pomace(8.5 kg/tree/year)in mid-December of each season vs.untreated trees.The bio-fertilizers were applied as N-fixing bacteria(150 g/tree)was inculated in early March of each season,or amino acid mixture(1.5%)was applied three times,at 70%of full bloom,21 days after full bloom,and a month later in comparison to a non-fertilized trees(control).The cultivar used was Kalamata,a dual-purpose cultivar for oil and table olives whose value increases when processed as table olives.The results indicated that the goat manure followed by olive pomace significantly enhanced photosynthetic pigments(chlorophyll a,b,and carotenoids),leaf mineral contents(N,P,K,Ca,Mg and Fe),tree canopy volume,number of flowers per inflorescence,number of inflorescences per shoot,initial fruit set,fruit retention.For fruit quality,fruit length and width,fruit weight,and total fruit yield was increased compared to the non-fertilized control.Likewise,The bio-fertilizer N-fixing bacteria followed by the amino acid mixture significantly improved all of the aforementioned parameters.Accordingly,it is recommended,both environmentally and economically to utilize organic and bio-fertizers,particularly goat manure combined with N-fixing bacteria,in low-fertility soil to sustain olive production as well as reducing mineral fertilization. 展开更多

The role of lactic acid bacteria for a correct course of fermentation of table olives has been extensively reviewed and it is a common idea that the inoculum of selected strains could exert a strong benefit for product quality;however, the basic assumption of this research is that a not-correct preparation of starter could affect its performances in brines and delay the benefit of a starter inoculum. Thus, some selected strains of LAB (lactic acid bacteria) and yeasts were inoculated into brines of Bella di Cerignola olives (Spanish style), as a single starter (LAB or yeasts) or a combined preparation (LAB + yeasts) and compared to a natural fermentation, focusing on the performances of the process (acidification, production of lactic acid) and trying to verify the basic assumption. LAB and yeasts were grown in the opportune lab media and then directly inoculated in brine after the lye treatment. LAB exerts a kind of benefit (increased content of lactic acid) only for 2 - 3 weeks;then, the inoculated samples behave in the same way as not-inoculated ones. Thus, this research underlined that a starter culture, not prepared in the correct way, could not be useful to guide the fermentation. 展开更多

In the Tunisian arid zones, where the soils are sandy and very poor in organic and mineral matters, wind erosion process is very active and triggered the departure of the thinnest elements of the soil and the apparition of dune building. Facing to these situations, many simple and efficient practices for combating desertification had been tested since many years in the Tunisian arid zones. The mulching of the olive mill wastewaters is one of these techniques. Otherwise, an olive mill wastewaters spray experimental device, with these respective doses of 50 m3/ha, 100 m3/ha and 200 m3/ha next to a witness parcel without OMW, has been putted in place since 1995 in the Chammakh-Zarzis, Tunisia. The mulching of the OMW, in the southern Tunisian regions constitutes an interesting alternative for the controlled and rational evacuation of this polluting sewage on the one hand and for the soil cohesion improvement by: (i) the increase of the organic matter rate which raised, in proportion to the dose, from 0.06% to 1.27% after 10 years of OMW mulching, and (ii) the improvement of the soil structural stability or ~'the mean weight diameter" where the aggregation rate superior to 2 mm is increased until 34% with the dose of 200 m3/ha. Therefore, that treatment will bind the sand particles and thereof control of sandstorms is gained. Indeed, the results in wind tunnel tests on the soil treated with these different doses of OMW showed that the threshold friction velocity u,t was raised from 8.5 m/s to 12 m/s for 50 m3/ha and 200 m3/ha, respectively. 展开更多

The purpose of this study was to assess the feasibility of growing olives along coastal Texas where the winter temperatures are relatively mild compared to most olive growing regions. For this purpose five sites along the Texas coastline (Seadrift, Galveston, Brazoria, Santa Fe, and Orange) were evaluated for feasibility of growing olives. In addition, two non-coastal sites (Carrizo Springs and Weslaco) were also included in the study for comparative purposes. Flowering and fruiting data were collected during four seasons starting from the 2005-2006 until the 2008-2009 season. In addition to the flowering and fruiting data, half-hourly temperature data were also collected at each site during each season. The results indicate that while olives can grow on all of the sites tested, there is a greater probability of success for commercial growing of olive between and along coastal sites where large scale experiment are highly recommended for rigorous evaluation of potential for commercial production of olives in these areas. In conclusion, there is a good probability that olives could be grown along the northeast coastline of Texas. 展开更多

Olive(Olea europaea)phytochemicals are associated with a reduced risk of type 2 diabetes.Table olives typically have higher phytochemical concentrations than olive oil,but their impact on human intestinal α-glucosidase is largely unknown.Shinzuke,the most common trade preparation in Japan,are alkali-treated non-fermented green olives.In contrast,natural olives are debittered by brining,which may enhance phytochemical retention.We evaluated theα-glucosidase inhibitory effect of Shinzuke and natural green olives produced in-house and compared them with commercial table olives.Eight types of table olives were tested against human intestinalα-glucosidase.Shinzuke Mission was the least effective(IC_(50) 0.710±0.058 mg/mL),while Natural green olives showed double to triple activity,with a non-competitive mechanism.Natural table olives retained more phytochemicals than shinzuke and other treated olives,and are good inhibitors of humanα-glucosidase in vitro,exhibiting potential as a functional food for the management of postprandial glycaemia. 展开更多

Table olives (Olea europaea L.) are one of the most important fermented vegetables worldwide, whereas sea fennel (Crithmum maritimum L.) represents an emerging food crop, characterized by interesting nutritional and sensory qualities. Both are characterized by a high concentration of bioactive compounds with health beneficial effects. Thanks to these features, table olives and sea fennel undoubtedly represent two valuable ingredients for the manufacture of innovative vegetable preserves. Given these premises, the present study was aimed at exploring the co-fermentation of green olives and sea fennel to produce laboratory-scale prototypes of innovative high value preserves. To this end, the effects of two recipes, two standard methods for production of table olives, and two fermentation microbiota (resident or inoculated) were assessed. The prototypes were evaluated for their microbial dynamics as well as for key sensory traits by a panel of trained assessors. During the fermentation, all the prototypes showed a progressive pH reduction. Mesophilic lactobacilli, mesophilic lactococci, and yeasts were the main microbial groups at the end of the fermentation, while Enterobacteriaceae decreased during fermentation. Metataxonomic analysis revealed an evolution of the microbiota, with Lactiplantibacillus plantarum dominating in all the prototypes in the late stage of fermentation, irrespective of the recipe, processing method, and starter inoculation. A greater crunchiness and lower fibrousness were perceived in the Greek style prototypes, which were preferred than Spanish style prototypes by trained panelists. 展开更多

In this work,we investigate how activated carbon(AC)derived from olive pomace biomass can be used as an anode material in lithium-ion batteries.The biomass-derived activated carbon has the potential to be highly efficient,deliver high performance,sustainable,and cost-effective in LIBs-related production.The activated carbon is prepared by using H3PO4 as a chemical activation agent,and then calcining the obtained product at 500℃ for different controlled atmospheres under(i)air(AC-Atm),(ii)vacuum(AC-Vac),and(iii)argon(ACArg).The different samples were systematically analyzed using scanning electron microscopy(SEM),Highresolution transmission electron microscopy(HRTEM),energy dispersive spectroscopy(EDS),X-ray fluores-cence(XRF),X-ray diffraction(XRD),FT-IR and Raman spectroscopy,and thermogravimetric analysis(TGA)to assess their properties.The electrochemical properties of the carbonaceous materials were studied by galvano-static cycling,cyclic voltammetry(CV),and electrochemical impedance spectroscopy(EIS).The results showed high specific capacity and stable cycling performance,with capacities of 288,184,and 56 mAh g^(-1) at the current density of 25 mA g^(-1) after 70 cycles for AC-Arg,AC-Vac,and AC-Atm respectively.Furthermore,the CE efficiency was nearly 100%from the first cycles.This study opens up interesting prospects and offers promising oppor-tunities for more efficient recovery of unused olive pomace waste,by integrating it into energy storage appli-cations,particularly sustainable lithium-ion batteries. 展开更多

Objective:Oleic acid,a subtype of monounsaturated fatty acid(MUFA),is present in abundance in certain edible oils,particularly olive oils.Epidemiological evidence concerning dietary oleic acid intake and the long-term risk of mortality is lacking.This study aimed to evaluate the associations of the dietary intake of oleic acid and other specific subtypes of MUFAs,olive oil,and other vegetable oils with cardiovascular disease(CVD)and all-cause mortality.Methods:This prospective cohort study included adults aged 40 years or older who participated in the included U.S.adults National Health and Nutrition Examination Survey(NHANES).Dietary MUFA intake was assessed via 24-h dietary recall interviews in NHANES 1999–2018,and the consumption of olive oil and other vegetable oils was assessed via a food frequency questionnaire in NHANES 2003–2006.Deaths and underlying causes of death were ascertained by linkage to the National Death Index through December 31,2019.Weighted Cox proportional hazards regression models were used to estimate the hazard ratio(HR)and 95%CIs.Results:Dietary intake of total MUFAs and oleic acid was associated with a lower risk of CVD mortality,with HRs(95%CI)of 0.62(0.39–0.99)and 0.61(0.39–0.97),respectively.Total MUFA and oleic acid intake were inversely associated with all-cause mortality;the multivariable-adjusted HRs were 0.77(95%CI:0.60–0.99)and 0.78(95%CI:0.62–0.99),respectively.There was no significant association between palmitoleic acid intake and all-cause mortality.The habitual consumption of olive oil,but not the consumption of other vegetable oils,was inversely associated with the risk of cardiovascular mortality.In the joint association analysis,the HRs(95%CI)of cardiovascular mortality were 0.36(0.19–0.69)for people who exclusively consumed olive oil,0.59(0.27–1.32)for people who consumed both olive oil and other vegetable oils,and 0.73(0.46–1.14)for people who exclusively consumed other vegetable oils compared with people who never consumed vegetable oils.Conclusions:In a U.S.nationally representative prospective cohort,higher dietary oleic acid intake and olive oil consumption were associated with a lower risk of cardiovascular mortality. 展开更多

The Mediterranean diet has long been recognized as one of the most effective ways to prevent and improve cardiovascular disease.Extra virgin olive oil(EVOO)is the typical sources of fat in the Mediterranean diet which have been shown to have noteworthy nutritional value and positive impact on human health.It is worth noting that EVOO owes its superior nutritional value to its bioactive composition.The main component of EVOO is monounsaturated fatty acids(MUFAs)in the form of oleic acid.Oleic acid accounts for up to 70%-80%of EVOO.Secondly,EVOO contains approximately more than 30 phenolic compounds,of which HT is essential for the protection against cardiovascular diseases.In this review,we focused on the potential mechanisms of oleic acid and polyphenols combat cardiovascular diseases risk in terms of oxidative stress,inflammation,blood pressure,endothelial function and cholesterol.This review might provide a reference for the studies on cardiovascular protective effects of EVOO. 展开更多

The regeneration of Tetracentron sinense Oliv.is poor in the understory and in open areas due to the charac-teristics of natural regeneration of the species on forest edges and in gaps.It is unclear whether different light intensities in various habitats affect eco-physiological characteristics of saplings and their natural regeneration.In this study,the light intensity in T.sinense habitats was simulated by artificial shading(L1:100%NS(natural sunlight)in the open;L2:50%NS in a forest gap or edge;L3:10%NS in understory)to investigate differences in morphology,leaf structure,physiology,and photosynthesis of 2-year-old sap-lings,and to analyze the mechanism of light intensity on sapling establishment.Significant differences were observed in morphology(including leaf area,and specific leaf area)under different light intensities.Compared to L1 and L3,chloroplast structure in L2 was intact.With increasing time,superoxide dismutase(SOD)and catalase(CAT)activities in L2 became gradually higher than under the other light intensities,while malondialdehyde(MDA)content was opposite.Shading decreased osmoregulation substance contents of leaves but increased chlorophyll.The results suggest that light intensities significantly affect the eco-physiological characteristics of T.sinense saplings and they would respond most favorably at intermediate levels of light by optimizing eco-physiological characteristics.Therefore,50%natural sunlight should be created to promote saplings establishment and population recovery of T.sinense during in situ conservation,including sowing mature seeds in forest edges or gaps and providing appropriate shade protection for seedlings and saplings in the open. 展开更多

Olive trees are susceptible to a variety of diseases that can cause significant crop damage and economic losses.Early detection of these diseases is essential for effective management.We propose a novel transformed wavelet,feature-fused,pre-trained deep learning model for detecting olive leaf diseases.The proposed model combines wavelet transforms with pre-trained deep-learning models to extract discriminative features from olive leaf images.The model has four main phases:preprocessing using data augmentation,three-level wavelet transformation,learning using pre-trained deep learning models,and a fused deep learning model.In the preprocessing phase,the image dataset is augmented using techniques such as resizing,rescaling,flipping,rotation,zooming,and contrasting.In wavelet transformation,the augmented images are decomposed into three frequency levels.Three pre-trained deep learning models,EfficientNet-B7,DenseNet-201,and ResNet-152-V2,are used in the learning phase.The models were trained using the approximate images of the third-level sub-band of the wavelet transform.In the fused phase,the fused model consists of a merge layer,three dense layers,and two dropout layers.The proposed model was evaluated using a dataset of images of healthy and infected olive leaves.It achieved an accuracy of 99.72%in the diagnosis of olive leaf diseases,which exceeds the accuracy of other methods reported in the literature.This finding suggests that our proposed method is a promising tool for the early detection of olive leaf diseases. 展开更多

The Tangier-Tetouan-Al Hoceima(TTA)region is one of the main olive oil producing regions in Morocco.Little is devoted to characterize olive oil physicochemical traits from TTA hence the originality of this study.It aimed at investigating variation in olive oil quality produced from three Moroccan cultivars‘Moroccan Picholine’,‘Menara’,and‘Haouzia’and their blends.Sampling was performed in five provinces fromTTA(Northern Morocco)during four consecutive crop-seasons(2018-2021)considering three extraction technologies(ET):traditional discontinuous press system(SP)and continuous extraction systems including decanter of three outlets(3O)and decanter of two outlets(2O).Physicochemical measurements consisted of routinely quality parameters namely free acidity(FA),peroxide value(PV),UV absorption parameters(K232,K270,andΔK),chlorophylls(Chl)and carotenoids(Car)contents,total phenolic compounds(TPC)and oxidative stability(OS).Crop season showed its superiority impacts on K232,OS,TPC,Chl,and OS.While cultivar was the main variability source in both PV and K270,and FA was mainly determined by ET.Important variations(p<0.05)were reported among crop seasons and locations due to pedoclimatic differences.‘Menara’and‘Haouzia’had higher pigments content,TPC,and OS,and the blends displayed low pigments concentration,TPC,and OS.Expectedly,continuous ET(2O and 3O)had the greatest values of pigments content,TPC,and OS as revealed by principal component analysis.Strong correlations were highlighted among basic quality parameters,TPC,pigments,and OS.Simple linear regression was used to describe the relationships between OS and TPC(R^(2)=0.856)and OS regressed against Chl(R^(2)=0.690)and Car(R^(2)=0.760),while TPC were regressed on Chl(R^(2)=0.670)and Car(R^(2)=0.680)and finally Chl against Car(R^(2)=0.931).In conclusion,compared to technological,genotypic,and geographic effects,climatic conditions were the main factor driving olive oil stability and associated phenolics and pigments;oil cultivar blend seems to have negative effects on pigments concentration and total phenolic compounds as well as oxidative stability. 展开更多

Precision agriculture(PA)is an agricultural management strategy based on observation,measurement and response to the variability of inter/intra-champ cultures.It includes advances in terms of data collection,analysis and management,as well as technological developments in terms of data storage and recovery,precise positioning,yield monitoring and remote sensing.The latter offers an unprecedented spatial,spectral and temporal resolution,but can also provide detailed information on the height of the vegetation and various observations.Today,the success of new agricultural technologies means that many agricultural tasks have become automated and that scientists have conducted more studies and research based on smart algorithms that automatically learn the decision rules from data.The use of Deep Learning(DL)and in particular the development and application of some of its algorithms called Convolutional Neural Networks(CNNs)are considered to be a particular success.In this work,we have applied and tested the performance of a network of convolutional neural network to automatically detect and map olive trees from Phantom4 drone imagery.The workflow involved the acquisition of images and the generation of ortho-mosaic with Pix4D software,as well as the use of a geographic information system.The results obtained with a training dataset of 4500 images of 24∗24 pixels are very satisfying:95%Precision,a 99%Recall and an F-score of 97%. 展开更多
