The synergistic effect between heavy metals and microplastics can affect soil properties as well plant performance yield. objective of this study was to evaluate the combined cadmium on a soil-plant system. Specifically, we proposed explore changes in microbiological activity, growth yield parameters strawberry plants, accumulation these pollutants root Plants were planted clay pots under greenhouse conditions. experiment set up completely randomized design, with four treatments (Control;...
Different concentrations of compost applied as organic fertilizer can modify productive, quality, and chemical parameters in several fruit tree species. The objective this study was to determine the effect increasing applications on physiological, quality calafate during seasons 2018–2019 2019–2020. conducted a commercial orchard using randomized complete block design with four treatments (CK: no application, T1: 5 Ton ha−1, T2: 10 T3: 15 ha−1), each repetitions. results did not show...
Abstract Background Brassicas ( Brassicaceae ) are recognized as excellent sources of nutrients and bioactive compounds. Among these, wild turnip Brassica rapa L.), holds significant promising nutritional properties owed to its abundant glucosinolates phenolic To enhance potential values, the application elicitors is crucial good strategy prompting an enrichment in concentration phytochemicals, well established other relevant Brassicas, such broccoli. While responses triggered by certain...
BACKGROUND: The pea aphid, Acyrthosiphon pisum (Harris), is a cosmopolitan pest that attacks wide range of legume crops and vectors important plant virus diseases. In this project, essential oils from the leaf (L) bark (B) Laurelia sempervirens (Ruiz & Pavón) Tul. Drimys winteri JR Forster G (D) were extracted, their deterrent insecticidal activities tested under laboratory conditions. RESULTS: By use GC-MS, safrole was found as main constituent in LL LB oils, while constituents more diverse...
The gut parasite Nosema ceranae is one of the most prevalent honey bee microsporidia worldwide and its chemical management in American countries mainly based on antibiotic fumagillin. However, it has recently been reported that this drug negative side effects bees; therefore, non-harmful alternative treatments must be found. methanolic extracts (2, 4, 8 16%) from Chilean native plant leaves (Aristotelia chilensis, Ugni molinae, Gevuina avellana) propolis (Biobío (BB) Los Ríos (LR) regions)...
One hundred twenty-five yeast strains isolated from table grapes and apples were evaluated for the control Botrytis cinerea of in vitro vivo. Ten selected their ability to inhibit mycelial growth B. vitro. In vivo assays, these yeasts tested at 20 °C on ‘Thompson Seedless’ berries 7 days; only three (m11, me99 ca80) because they significantly reduced incidence gray mold. These then different concentrations (1 × 107, 1 108 109 cells mL−1) grape °C. The m11, ca80 11.9, 26.1 32.1%,...
The worldwide spread of diseases is considered a major threat to biodiversity and possible driver the decline pollinator populations, particularly when novel species or strains parasites emerge. Previous studies have suggested that populations introduced European honeybee (Apis mellifera) bumblebee (Bombus terrestris Bombus ruderatus) in Argentina share neogregarine parasite Apicystis bombi with native dahlbomii). In this study we investigated whether A. acting as an emergent non-native...
The pea weevil (Bruchus pisorum L.) (Coleoptera: Bruchidae) is one of the most damaging pests (Pisum sativum We investigated role volatiles on electrophysiological and behavioral response B. using electroantennography (EAG) olfactometry bioassays.Plant emitted at different phenological stages were collected in situ by headspace Porapak Q traps analyzed through gas chromatography coupled to mass spectrometry (GC-MS).Most abundant identified all terpenes green leaf volatiles.All tested...
Abstract From the bark of Drimys winterii Forst., drimane derivatives drimendiol, polygodial, isotadeonal and isodrimeninol were isolated. Complete unambiguous 1 H 13 C NMR chemical shift assignments these compounds achieved by COSY experiments, C/ correlation diagrams NOE experiments. Isotadeonal found for first time in this plant species. Copyright © 2004 John Wiley & Sons, Ltd.
Insect behavior is coordinated mainly by smell through the diverse odor-binding proteins (OBP) that allow them to identify and recognize their environment. Sensory information collected then analyzed interpreted in brain, allowing for correct insect functioning. The of honeybees (Apis mellifera L.) can be affected different pathogens, such as deformed wing virus (DWV). In particular, DWV variant A (DWV-A) capable altering olfactory sensitivity reducing gene expression OBPs, including those...
Crop production is being impacted by higher temperatures, which can decrease food yield and pose a threat to human nutrition. In the current study, edible wild radish sprouts were exposed elevated growth temperatures along with exogenous application of various elicitors activate defense mechanisms. Developmental traits, oxidative damage, glucosinolate anthocyanin content, antioxidant capacity evaluated alongside development predictive model. A combination four (citric acid, methyl...
Different episodes of mortalities honey bee (Apis mellifera L.) colonies have been associated with the presence pathogens.Since Biobío Region has among highest number apiaries in Chile, aim present study was to identify viruses affecting bees, evaluate their relation other pathogens, and conduct a phylogenetic analysis.Pupae adult bees were collected from 60 Apis L. over 2 yr.RNA detected by reverse transcription PCR (RT-PCR), Acarapis woodi, Nosema spp., Varroa destructor via PCR.Three...
The honeybee (Apis mellifera L.) is an important pollinator worldwide. Beekeepers have experienced increasing loss of colonies in recent years and pathologies including viruses intestinal parasites such as Nosema ceranae are among those held responsible for this decline. aim study was to determine the prevalence distribution, using real time PCR method, six Deformed Wing Virus (DWV), Black Queen Cell (BQCV), Sacbrood (SBV), Acute Bee Paralysis (ABPV), Chronic (CBPV) Israeli (IAPV) addition...
Blueberry production under netting has increased in recent years to mitigate the adverse effects of climate change. The objective present study was evaluate effect different radiation intensities on rabbit-eye blueberry (Vaccinium virgatum Aiton) 'Ochlockonee' photosynthetic efficiency and productive parameters. Four treatments were established: T1 (control), T2, T3, T4 at 0%, 30%, 60%, 90% decrease (RD), respectively, with black shedding netting. following recorded for each treatment:...
