Variation in the impact of stem scar and cuticle on water loss in highbush blueberry fruit argue for the use of water permeance as a selection criterion in breeding
(Elsevier, 2017)The role of fruit scar on water loss from fresh harvested, fully blue highbush blueberry (Vaccinium corymbosum L.) fruit was studied on three germplasm lines from each of three half-sib families at University of Talca, ... -
Volatile composition and enantioselective analysis of chiral terpenoids of nine fruit and vegetable fibres resulting from juice industry by-products
(Hindawi Publishing Corporation, 2017)Fruit and vegetable fibres resulting as by-products of the fruit juice industry have won popularity because they can be valorised as food ingredients. In this regard, bioactive compounds have already been studied but little ... -
Volatile emission after controlled atmosphere storage of Mondial Gala apples (Malus domestica): relationship to some involved enzyme activities
(American Chemical Society, 2007)Mondial Gala apples were harvested at commercial maturity and stored at 1 °C under either air or controlled atmosphere (CA) conditions (2 kPa O2/2 kPa CO2 and 1 kPa O2/1 kPa CO2), where they remained for 3 or 6 months. ... -
Volatile ester-synthesising capacity in 'Tardibelle' peach fruit in response to controlled atmosphere and 1-MCP treatment
(Elsevier, 2010)Peach fruit is highly perishable, which drastically restricts storage potential and marketing possibilities. Although aroma is a very important attribute for sensory quality of peach, post-harvest procedures, aimed at ... -
Volatile production, quality and aroma-related enzyme activities during maturation of ‘Fuji’ apples
(Elsevier, 2004)Production of volatile aroma compounds, and quality parameters, were monitored in relation to the activity of lipoxygenase, pyruvate decarboxylase, alcohol dehydrogenase and alcohol o-acyltransferase during maturation of ... -
Voltammetric currents for any ligand-to-metal concentration ratio in fully labile metal-macromolecular complexation. Easy computations, analytical properties of the currents and graphical method to estimate the stability constant
(Elsevier, 1999)In order to enable a wider use of voltammetric methods in speciation analysis, it is convenient not to be restricted by ligand excess conditions. This work assumes labile ideal complexation of a metal ion by a ligand, ... -
Voltammetric lability of metal complexes at spherical micorelectrodes with various radii
(Elsevier, 2001)The size of a microelectrode can have a dramatic impact on the relative importance of the diffusional and kinetic contributions to the voltammetric current of an electroactive metal ion in a complexing medium. Decreasing ... -
Voltammetric lability of multiligand complexes: the case of ML2
(Elsevier, 2004)The voltammetric lability of a complex system, where a metal ion M and a ligand L form the species ML and ML2, is examined. Together with the rigorous numerical simulation of the problem, two limiting cases are analysed ... -
Vuelos de la defoliadora de maíz, pastos y céspedes, Mythimna (Pseudaletia) unipuncta (Haworth) en la zona de Lleida
(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 2000)Mythimna unipuncta causa daños en gramíneas cultivadas (principalmente maíz) y céspedes cuya importancia ha ido aumentando los últimos años. En nuestra región presenta cuatro vuelos de adultos. Los daños causados por la ... -
Whole-genome analysis with SNPs from BOPA1 shows clearly defined groupings of Western Mediterranean, Ethiopian, and Fertile Crescent barleys
(Springer Verlag, 2013)The discovery of Hordeum spontaneum C. Koch, a wild ancestor of cultivated barley, in Morocco in 1978 led to the proposal of a multicentric origin for this crop, as an alternative to the widely accepted theory of a single ... -
Within-plant variability in blueberry (Vaccinium corymbosum L.): maturity at harvest and position within the canopy influence fruit firmness at harvest and postharvest
(Elsevier, 2018)For blueberry, harvest readiness is based on skin color, with fruit being considered ready to pick when the berry skin reaches 100 % blue coverage. The extended bloom period for the blueberry inflorescence and uneven ...
