Plums varieties Jubileum, Excalibur and Reeves were harvested at commercial harvest date. After harvest fruits were dipped in hot water (56 °C) for 2 minutes then they were cooled down in cool water. Fruits were stored for 4 weeks in normal atmosphere (NA) and modified atmosphere (MAP) in xtend packaging film. In equilibrium state,modified atmosphere consisted of 10 % of O2 and 10 % of CO2. Excalibur contained the highest amount of total phenols, followed by Jubileum and Revees, while Jubileum had the highest antioxidative potential (AOP) followed by Excalibur and Revees. Significantly more total phenols was found at second week of storage followed by forth week and after harvest. On the other hand, Revees contained significantly more flavonoids, followed by Excalibur and Jubileum. The highest antioxidative potential was found immediately after harvest followed by that of 4 weeks storage and finally that of 2 weeks storage time. Significantly more flavonoids were found at the beginning of storage and least at the end of storage. Plums stored in modified atmosphere had the highest AOP, followed by NA, MAP hot water (HW) treated and NA hot water treated fruits. With regard to storage conditions, more flavonoids were found in NA stored plums, followed by MAP HW, MAP and NAHW. Revees had the highest polar AOP followed by Jubileum and Excalibur, but no statistically significant differences were found. Also the highest polar AOP was found in forth week of storage again no statistically significant differences were found. Storage atmosphere gave no statistically significant differences in polar AOP. Results showed that storage conditions influence the AOP, total phenols and flavonoids. Flavonoids are more abundant after harvest, total phenols in the middle of storage period. Hot water treatment is becoming popular because might be used for organically grown fruits and vegetables. In our experiment hot water treatment showed e tendency to decrease AOP, flavonoids and polar AOP but significantly decreases total phenols.

Abstract
Local climate conditions have a major influence on the biological decomposition of wood. To examine the influence of different temperature regimes on wood decay caused by the brown rot fungus Postia placenta in wood with differing natural durability, sapwood (sW) and heartwood (hW) of Scots pine, inoculated mini-blocks were incubated for up to 10 weeks at temperatures conducive or above optimal to wood decay. We profiled mass loss (ML) and wood composition, and accompanying changes in wood colonization and transcript level regulation of fungal candidate genes. The suppressive effect of suboptimal temperature on wood decay caused by P. placenta appeared more pronounced in Scots pine hW with increased durability than in sW with low decay resistance. The differences between sW and hW were particularly pronounced for cultures incubated at 30°C: unlike sW, hW showed no ML, poor substrate colonization and marker gene transcript level profiles indicating a starvation situation. As brown rot fungi show considerable species-specific variation in temperature optima and ability to mineralize components that contribute to wood durability, interactions between these factors will continue to shape the fungal communities associated to wood in service.
