Use of Biostimulants for Organic Apple Production: Effects on Tree Growth, Yield, and Fruit Quality at Harvest and During Storage
2018
The experiment was conducted during two consecutive seasons (years 2016 and 2017) in an organic apple orchard of the cultivar Jonathan. Several biostimulants were tested (10 in total), including humic acids, macro and micro seaweed extracts, alfalfa protein hydrolysate, amino acids alone or in combination with zinc, B-group vitamins, chitosan and a commercial product containing silicon. Treatments were performed at weekly intervals, starting from the end of May until mid-August. The macroseaweed extract was effective in stimulate tree growth potential in both years, as shown by a significantly larger leaf area (+20% as compared to control) and by an higher chlorophyll content and leaf photo…
Maternally‐transferred thyroid hormones and life‐history variation in birds
2022
1. In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early-phase embryonic development when embryos are not able to produce endogenous THs. Previous studies have shown that variation in maternal THs within the physiological range can influence offspring phenotype. 2. Given the essential functions of maternal THs in development and metabolism, THs may be a mediator of life-history variation across species. 3. We tested the hypothesis that differences in life histories are associated with differences in maternal TH transfer across species…

ESBL producējošu Enterobacteriaceae dzimtas baktēriju izpēte stacionētiem pacientiem
2018
Pēdējo gadu laikā par vienu no nopietnākajiem sabiedrības veselības apdraudējumiem visā pasaulē un arī Latvijā tiek uzskatīta antimikrobā rezistence. Arvien biežāk tiek ziņots par slimnīcas apstākļos iegūtām antibakteriālo līdzekļu rezistentu Enterobacteriaceae celmu izraisītām infekcijām. Pētījuma mērķis bija raksturot paplašināta spektra beta laktamāzes (ESBL) producējošās Enterobacteriaceae dzimtas baktērijas zarnu mikrobiotā. Apkopojot pētījuma datus, secināja, ka, izstājoties no slimnīcas, 45 (33,09%) no RAKUS 136 stacionētajiem “Biķernieki” pacientiem bija ESBL producējošo Enterobacteriaceae nēsātāji zarnu traktā. Visbiežāk sastopamais rezistences gēns (PCR metode) ESBL producējošās E…
Technical English for agriculture
2021
As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…
Soil inoculation with symbiotic microorganisms promotes plant growth and nutrient transporter genes expression in durum wheat
2015
In a field experiment conducted in a Mediterranean area of inner Sicily, durum wheat was inoculated with plant growth-promoting rhizobacteria (PGPR), with arbuscular mycorrhizal fungi (AMF), or with both to evaluate their effects on nutrient uptake, plant growth, and the expression of key transporter genes involved in nitrogen (N) and phosphorus (P) uptake. These biotic associations were studied under either low N availability (unfertilized plots) and supplying the soil with an easily mineralizable organic fertilizer. Regardless of N fertilization, at the tillering stage, inoculation with AMF alone or in combination with PGPR increased the aboveground biomass yield compared to the uninocula…
Perception of pathogenic or beneficial bacteria and their evasion of host immunity: pattern recognition receptors in the frontline
2015
International audience; Plants are continuously monitoring the presence of microorganisms to establish an adapted response. Plants commonly use pattern recognition receptors (PRRs) to perceive microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) which are microorganism molecular signatures. Located at the plant plasma membrane, the PRRs are generally receptor-like kinases (RLKs) or receptor-like proteins (RLPs). MAMP detection will lead to the establishment of a plant defense program called MAMP-triggered immunity (MTI). In this review, we overview the RLKs and RLPs that assure early recognition and control of pathogenic or beneficial bacteria. We also highlight the crucial func…

Quel che resta dell’amore. I “Versi a Dina” di Camillo Sbarbaro
2011
Lettura dei “Versi a Dina”, canzoniere amoroso sbarbariano pubblicato nel ’31 su «Circoli», e confluito nella silloge del ’55 “Rimanenze”. Imperniato su una dialettica costante fra impotenza soggettiva a riesumare il tempo trascorso, ed evidenza oggettiva che presentifica il ricordo, il racconto dell’amore perduto è qui analizzato in chiave intertestuale, in termini di continuità-discontinuità col precedente poemetto “Pianissimo, di cui condivide un analogo repertorio topico e lessicale, seppur riscattato da un riacquisto di fiducia nella parola.
«Nos iuvat herbas legere» o l’umile poesia della natura
2009
Non è difficile individuare, ripercorrendo l’opera di Camillo Sbarbaro, una significativa tangenza fra il desolato mondo dell’artista, dominato dall’immagine della «città di pietra» e della natura ruvida ed aspra, e il misterioso mondo dei licheni, che abitano petraie, rovine solatie, muri a secco di calce e sabbia. Al centro di questo studio è appunto il confronto intertestuale fra gli scritti inventivi e quelli scientifici del poeta ligure, entrambi all’insegna dell’umile poesia della natura.
