Contenido :  ABSTRACT. Feijoa (Acca sellowiana (Berg.) Burret) is one of the most popular native Uruguayan trees whose functional characteristics have attracted the interest for commercial cultivation. The aim of this work was to evaluate the postharvest behavior of six genetic materials, identified as 95, 97, 98, 152, 153 and 154 from the Facultad de Agronomía and Instituto Nacional de Investigación Agropecuaria (INIA, Uruguay) breeding program. Fruits harvested at two maturity stages (M1: not easily picked; M2: touch picking) were stored for 0, 15 and 30 days at 5°C and 95% relative humidity (RH) plus 7 days at 18°C (shelf life). Respiration rates and ethylene emissions were measured every 3 days, while flesh firmness, weight loss and total polyphenol content were evaluated at the end of the storage period and during shelf life. The respiration rate of all the genetic materials was around 27.6 mg kg-1 h-1 of CO2 during the storage period, while ethylene emission was maintained below 100 µL kg-1 h-1 without differences among maturity stages and genetic materials. Fruits harvested at the M1 stage were 40-60% more firm than fruits harvested at the M2 stage. Genetic materials identified as 95 and 98 had the highest firmness results, with values of 150.1 and 145.1 N (M1), 112.6 and 90.4 N (M2) at harvest and 28.8 and 17.4 N (M1) and 17.2 and 15.4 N (M2) after 30 days at 5°C + 7 days at 20°C, respectively. Average weight loss at the end of storage (30+7) was 14.7%. Fruits identified as mater... Presentar Todo

Título :  Light avoidance reduces ascorbic acid accumulation in the peel of Citrus fruit.

Contenido :  ABSTRACT. Citrus fruits are highly consumed worldwide and represent one of the most important sources of ascorbic acid (AsA). However, information about the molecular mechanisms regulating AsA accumulation in Citrus fruit and the effects of environmental factors is scarce. In this study we have investigated the effect of fruit shading on AsA content and the expression of AsA biosynthetic, degrading and recycling genes in fruits of different Citrus species. Immature-green fruits were covered at the end of the cell enlargement phase and AsA concentration in the flavedo declined and remained at low levels as compared with light-exposed fruits. Fruit shading marginally altered the expression of genes from the l-galactose pathway and this effect was variable in the four Citrus species. However, specific isoforms (GalUR8 or GalUR12) from the l-galacturonic acid pathway were significantly repressed paralleling the reduction in AsA concentration. No significant effect of shading was detected in transcription of genes of the myo-inositol and l-gulose pathways as well as recycling and degradation. Collectively, results indicate that light avoidance inhibited accumulation of AsA in the flavedo of Citrus fruits and suggest that the l-galacturonic acid pathway has a relevant contribution to AsA content in this tissue.
