Thirteen species of wild edible plants belonging to 11 botanical families consumed in the traditional Mediterranean diet were evaluated. Sanguisorba minor, Quercus ballota and Sedum sediforme showed highest hydrophilic total antioxidant activity (H-TAA) phenols. Asparagus acutifolius, Allium ampeloprasum, Foeniculum vulgare Malva sylvestris presented high levels potassium, are interesting due their zinc content, Urtica urens contains a content calcium. Sensory analysis indicated that fruits...

In the present manuscript short term effect (3-24 h) of a saline shock (NaCl 100 mM) on fresh weight, water content, respiration rate, ethylene production and Na+, Cl-, ACC polyamine concentration was studied in four plant species with different salt sensitivity, pepper, lettuce, spinach, beetroot. Higher reduction weight content as consequence found pepper lettuce plants than spinach beetroot, latter behaving more salinity tolerant. general, led to rapid increases (putrescine, spermidine,...

Physico-chemical and physiological changes during development ripening of five loquat cultivars ( Eriobotrya japonica Lindl., cv. Algerie, Cardona, Golden, Magdall Peluche) were determined. Fruit growth showed a sigmoid curve in all cultivars. A good relationship between duration fast phase fruit size was found. In addition, positive correlation also established seed number size, weight both flesh weight. Colour changes, sugar content increase the decrease firmness organic acids started...

Some parameters related to nutritive and functional properties were evaluated in date fruit from seven palms the Elche grove along maturation process, order obtain information about differences due phenotypic variability. Results showed that sugar organic acid concentration different depending on palm, highest levels being reached at 100% Rutab stage, with glucose fructose as predominant sugars malic major acid. Hydrophilic total antioxidant activity (HTAA) was high correlated phenolic...

Bell pepper fruit (Capsicum annuum L. cv. Lamuyo) at two stages of maturity, mature green (MG) and red (MR), were stored 2 10 °C to investigate physiological changes resulting from chilling injury. The MG showed evidence injury (surface pitting) when °C, while MR unaffected by cold. At the same time, differences in evolution plant regulators detected: In chilling-sensitive peppers, ethylene levels 1-aminocyclopropane-1-carboxylic acid (ACC), putrescine (Put), abscisic (ABA) rose...

Loquat fruits (Eriobotrya japonica Lindl cv. `Algerie') were stored in modified atmosphere packaging (MAP), using five types of microperforated polypropylene (PP) films during 2, 4, and 6 weeks at 2 °C for a subsequent period 4 days 20 shelf life (SL) out the bags. without normal air served as control. The composition steady state depended on film permeability, ranging from 1.2 to 8.5 kPa CO 19.5 13 O permeability decreased. Weight loss was drastically reduced by MAP conditions. Softening,...

Zucchini squash showed chilling injury (CI) damage as pitting on 93% of their surface after 12 days at 2 °C, and a 2−2.5-fold increase in putrescine levels both skin pulp was detected during storage (from 162 38 to 320 98 nmol g-1 fresh weight, respectively). Abscisic acid concentration increased mainly the skin. Treatments with CO2 prior °C were found be effective reducing CI. With 5% CO2, increases abscisic lower than control fruits, while exposure 40% resulted decrease these values....

Some physicochemical parameters related to ripening and their relationship with ethylene were studied in date fruits ( Phoenix dactyliferaL. type Negros). Dates harvested classified into sixteen stages according color, ranging from yellow-greenish dark brown. Fruit firmness decreased through the different stages, while index, expressed as relation between soluble solids acidity, increased. The greatest loss of fruit correlated increases both polygalacturonase •-galactosidase activities. In...

Some tropical and subtropical fruit vegetables suffer chilling injuries (CI) when exposed to low (above freezing) temperatures. The symptoms of such vary between species, although they usually involve staining the peel internal browing, are related important modi fications at cell membrane level. polyamines putrescine, spermidine spermine, have an antisenescent action because their capacity link with anionic compounds in capture free radicals, thus stabilizing lipid bilayer preventing...

This work indicates that cherimoya behaves like a climacteric fruit after harvesting, because it shows respiration and ethylene crises connected with its ripening. The increase in production is caused by an the activities of ACC-synthase ethylene-forming enzyme (EFE), which are very low freshly picked fruit, but rapidly over second day, reaching maximum on third day. During there also amount 1-aminocyclopropane-l-carboxylic acid (ACC) conjugated form. Skin browning increases this not related...
