Climate changes boosted the frequency and severity of drought heat events, with aggravated when these stresses occur simultaneously, turning crucial to unveil plant response mechanisms such harsh conditions. Therefore, responses/resilience single combined exposure severe water deficit (SWD) were assessed in two cultivars main coffee-producing species: Coffea arabica cv. Icatu C. canephora Conilon Clone 153 (CL153). Well-watered plants (WW) exposed SWD under an adequate temperature 25/20°C...
Abstract The tropical coffee crop has been predicted to be threatened by future climate changes and global warming. However, the real biological effects of such remain unknown. Therefore, this work aims link physiological biochemical responses photosynthesis elevated air [ CO 2 ] temperature in cultivated genotypes C offea arabica L. (cv. Icatu IPR 108) Coffea canephora cv. Conilon CL 153. Plants were grown for ca. 10 months at 25/20 °C (day/night) 380 or 700 μl l −1 then subjected increase...
Modelling studies have predicted that coffee crop will be endangered by future global warming, but recent reports highlighted high [CO2] can mitigate heat impacts on coffee. This work aimed at identifying protective mechanisms promoted CO2 in Coffea arabica (cv. Icatu and IPR108) C. canephora cv. Conilon CL153. Plants were grown 25/20 ºC (day/night), under 380 or 700 μL L-1, then gradually submitted to 31/25, 37/30 42/34 ºC. Relevant tolerance up for both all genotypes was observed, likely...
Climate changes, mostly related to high temperature, are predicted have major negative impacts on coffee crop yield and bean quality. Recent studies revealed that elevated air [CO2] mitigates the impact of heat leaf physiology. However, extent interaction between quality was never addressed. In this study, single combined enhanced temperature in beans Coffea arabica cv. Icatu were evaluated. Plants grown at 380 or 700 μL CO2 L-1 air, then submitted a gradual rise from 25°C up 40°C during ca....
Coffee is one of the world's most traded agricultural products. Modeling studies have predicted that climate change will a strong impact on suitability current cultivation areas, but these not anticipated possible mitigating effects elevated atmospheric [CO2] because no information exists for coffee plant. Potted plants from two genotypes Coffea arabica and C. canephora were grown under controlled conditions irradiance (800 μmol m-2 s-1), RH (75%) 380 or 700 μL CO2 L-1 1 year, without water,...
In the present work some dehydration-induced responses at whole plant and cellular levels were evaluated in three Vigna genotypes (V. glabrescens, Vg; V. unguiculata cv. EPACE-1; 1183) from different origins. Changes leaf stomatal conductance (gs), membrane lipids composition abscisic acid (ABA) content determined under water stress. Membrane integrity was assessed through discs dehydration with polyethylene glycol (PEG 8000, -1.3 MPa), expressed as an injury index (I%).. EPACE-1 1183, rapid...
The understanding of acclimation strategies to low temperature and water availability is decisive ensure coffee crop sustainability, since these environmental conditions determine the suitability cultivation areas. In this context, impacts single combined exposure drought cold were evaluated in three genotypes two major cropped species, Coffea arabica cv. Icatu, canephora Apoatã, hybrid Obatã. Crucial traits plant resilience stresses have been examined: photosynthesis, lipoperoxidation...
Abstract Growing water restrictions associated with climate changes constitute daunting challenges to crop performance. This study unveils the impacts of moderate (MWD) or severe (SWD) deficit, and their interaction air [CO2], on photosynthetic apparatus Coffea canephora Pierre ex A. Froehner cv. Conilon Clone 153 (CL153) arabica L. Icatu. Seven year-old potted plants grown under 380 (aCO2) 700 μl l −1 (eCO2) [CO2] gradually reached predawn potentials between −1.6 −2.1 MPa (MWD), below −3.5...
This study unveils the single and combined drought heat impacts on photosynthetic performance of
Coffea arabica L. is as a tropical crop that can be grown under monocrop or agroforestry (AFS) systems, usually at altitudes greater than 600 m, with suitable environmental conditions to bean quality. This study aimed assess the effect of altitude (650, 825, and 935 m) light (deep shade—DS, moderate shade—MS provided by native trees, full Sun—FS) on physical chemical attributes green coffee beans produced in Gorongosa Mountain. Regardless altitude, (mainly MS FS) scarcely affected most...
Fatty acid content and composition of chloroplast membranes, ethylene production associated with thylakoid lipids degradation as well photosynthetic electron transport involving photosystems 1 2 were used to determine the effects increasing Cd concentrations in growth medium [0, 14, 28, 42 mg (Cd) kg-1(sand)] on performance barley plants (H. vulgare L., cv.

International Accounting Standard (IAS) 41 for Biological Assets establishes guidelines accounting live assets and agricultural products, which in this case was taken into account an analysis the poultry industry. This standard seeks to standardize processes with measurement of biological at fair value; industry, proper is a problem, due economic nature birds, addition their growth valuation various stages development. IAS enables firms properly recognize revenues expenses associated these...
Abstract Four genotypes of Triticum aestivum L. and turgidum subsp . durum chosen according to their genetic background diversity were subjected heat stress after anthesis. Membrane permeability, lipid peroxidation fatty acids (C14:0, C16:0, C16:1 c , t C18:0, C18:1, C18:2 C18:3) quantified. The estimation the quantum yield non‐cyclic photosynthetic electron transport was used as well a test system further evaluate implications on thylakoid functioning. It found differences within bread...
To search for culturable Burkholderia species associated with annual ryegrass in soils from natural pastures Portugal, plant growth‐promoting effects. Annual seedlings were used to trap two different laboratory conditions. A combined approach using genomic fingerprinting and sequencing of 16S rRNA recA genes resulted the identification strains belonging graminis, fungorum cepacia complex. Most able solubilize mineral phosphate synthesize indole acetic acid; some them could produce...
