The aim of the study was to determine the effect of modified atmosphere (MA) packages on the external quality of organically grown lowbush blueberry and half-highbush blueberry (’Northblue’) and the nutritional value of the fruits. Fruits were divided into plastic punnets and stored as follows: regular atmosphere (RA), punnets without packing; punnets sealed in a low-density polyethylene (LDPE, Estiko) bag; punnets sealed in an Xtend® blueberry bag (Stepac). Fruits were stored at 3 ± 1 ◦C. Compared to RA conditions, the Xtend® package prolonged the postharvest life for 15 days for lowbush and 9 days for half-highbush blueberries. Fruit dry matter (DM) and titratable acidity (TA) were higher in the Xtend® package. Fruit SSC decreased in the LDPE packages and increased in the Xtend® packages during storage. Based on the decreased soluble solids content (SSC) and titratable acidity (TA) ratio (SSC:TA) values during storage, it can be concluded that the taste of the fruits became sourer in all packages. Anthocyanin biosynthesis of lowbush blueberries was suppressed in MA, but this effect was not noticed for ‘Northblue’. Regarding fruit firmness, shrivelling, and decay, there were significant differences between the MA packages, but the genetic differences were more important: half-highbush blueberry fruits were firmer and less shrivelled.

The sentinel plants concept responds to the need for new strategies to identify and study potential plant pests (including pathogens) and assess associated risks before their introduction to other continents. However, even if very promising, this tool is not yet implemented on a large scale, partially because it requires adequate planning, long-term funding, strong local links and reliable collaborators. In addition, a wider implementation of sentinel plantations and sentinel nurseries requires knowledge of regulations and procedures regarding the possibilities for their establishment in different countries. In order to achieve this objective, a questionnaire survey was conducted in 2016, to which more than 40 countries around the world responded. The results reveal that many countries have few regulations specifically concerning the import of propagation material, making import of this relatively low-risk material easier than the import of larger living plants that may have been more exposed to pests in the exporting country. The planting of alien woody plants in the environment is possible for scientific purposes in most countries as exemption from general phytosanitary import requirements, but the import and planting of alien plant species may be regulated by different government departments. We will present the outcomes of this study, which will be useful to facilitate the selection of locations for future sentinel plants and may provide guidance on the rules for import of plant propagation material for the establishment of sentinel plants and sentinel nurseries in different countries.
