A general response of plants to high soil salinity relies on the cellular accumulation osmolytes, which help plant maintain osmotic balance under salt stress condition and/or act as ‘osmoprotectants’ with chaperon or reactive oxygen species (ROS) scavenging activities. Yet ecological relevance this for tolerance mechanisms halophytes in their natural habitats remains largely unknown. In review, we describe and discuss published data supporting participation compatible solutes those...

In their natural habitats, different mechanisms may contribute to the tolerance of halophytes high soil salinity and other abiotic stresses, but relative contribution ecological relevance, for a given species, remain largely unknown. We studied responses changing environmental conditions five (Sarcocornia fruticosa, Inula crithmoides, Plantago crassifolia, Juncus maritimus J. acutus) in Mediterranean salt marsh, from summer 2009 autumn 2010. A principal component analysis was used correlate...

Compartmentalization of toxic ions in the vacuole and accumulation osmolytes cytoplasm is a common response halophytes to high soil salinity. Soluble carbohydrates, such as sugars polyols, are some compatible solutes used for osmotic adjustment osmoprotection. Major carbohydrates were identified quantified by high-performance anion-exchange chromatography, combined with pulsed amperometric detection (HPAEC-PAD), five halophytic species from Mediterranean salt marsh (Juncus acutus, Juncus...

Presently, there is a growing interest in developing new controlled-release fertilizers based on ecological raw materials.

Background: Antimicrobial resistance (AMR) represents a critical global health challenge, requiring innovative strategies to combat resistant bacterial strains. Cymbopogon essential oils (EOs) are promising natural antimicrobial agents. Methods: The EO of commutatus was extracted by hydrodistillation from fresh aerial parts and compared commercial EOs C. citratus, nardus, winterianus. Antibacterial activity evaluated against seven strains (two Gram-positive five Gram-negative). Both...

Thinning is a practice that reduces competition for available soil resources, thereby promoting vegetation growth and affecting soil, which involved in important ecosystem processes. Soil quality directly influenced by various aspects such as ground cover, regional climate, local microclimate, can further be modified forest thinning. In this study, the effect of tree thinning climate on microbiological enzymatic properties was investigated an Aleppo pine (Pinus halepensis M.) more than...

Biostimulants’ application to plants can reduce the damage caused by abiotic factors such as drought or salinity and improve crop yield under these stressful conditions. In this work, several biostimulants, namely Terrabion Aminovit® (a commercial product based on amino acids), potassium fulvate, humic acids, a seaweed extract, were applied cherry tomato using fertigation at two doses of 0.2 1.0 g L−1. The then subjected water stress treatment completely withholding irrigation for 12 days....

Increasing nutrient use efficiency of fertilizers is one the major challenges to improve crop yields and minimize environmental impacts. This work compared efficacy a new ecological polymer-coated urea fertilizer slow release urea-based traditional fertilizer. Reductions in N doses were tested. A comparative study was first carried out by measuring different physiological yield parameters at micro-scale level, later-on field experiments performed. Grain significantly higher (20%) when...

Micronutrients are essential to plants, and enhancing their availability is one of the agronomic challenges improving crop quality yield. This study, under controlled greenhouse conditions, compares tomato plants’ responses two different micronutrient EDTA-chelated formulations, them including a newly developed fulvate–lignosulfonate coating. Growth, yield, several physiological parameters, photosynthetic gas exchange, water-use efficiency, leaf nutrient content, greenness effective quantum...

Abstract Up to date, soil application of synthetic chelates is the most effective mean controlling iron (Fe) deficiency chlorosis in many crops. The responses three representative soils (I, II, and III) a large orchard area (Ribera Alta del Jucar) commercial Fe-EDDHA (Sequestrene 138 Fe G-100, Group Carla Val F.E.A 6 Superior Ferrishell plus) at 100 (D1) 200 µg Fe/kg (D2) were analyzed. Extractable concentrations Fe, copper (Cu), manganese (Mn), zinc (Zn) determined 7, 14, 21, 42, 71 days...

Background A new controlled-release pheromone 1,7-dioxaspiro[5,5]undecane dispenser has been developed, which is useful for monitoring the population and controlling Bactrocera oleae (Rossi, 1790) (Diptera: Tephritidae). For this purpose, several kinds of dispensers based on attapulgite were designed tested in study. Results The dispensers, together with commercial-brand olive fruit fly ‘Long-Life Lure’, was used as a reference, evaluated field, parallel subjected to an accelerated ageing...
