Hence, pollination is underestimated by international policies, which is particularly alarming in times of agricultural intensification and diminishing pollination services. In this study, exclusion experiments with strawberries showed bee pollination to improve fruit quality, quantity and market value compared with wind and self-pollination. Bee-pollinated fruits were heavier, had less malformations and reached higher commercial grades. They had increased redness and reduced sugar–acid–ratios and were firmer, thus improving the commercially important shelf life. Longer shelf life reduced fruit loss by at least 11%. This is accounting for 0.32 billion US$ of the 1.44 billion US$ provided by bee pollination to the total value of 2.90 billion US$ made with strawberry selling in the European Union 2009. The fruit quality and yield effects are driven by the pollination-mediated production of hormonal growth regulators, which occur in several pollination-dependent crops. Thus, our comprehensive findings should be transferable to a wide range of crops and demonstrate bee pollination to be a hitherto underestimated but vital and economically important determinant of fruit quality."],["dc.identifier.doi","10.1098/rspb.2013.2440"],["dc.identifier.gro","3149853"],["dc.identifier.pmid","24307669"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6557"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0962-8452"],["dc.title","Bee pollination improves crop quality, shelf life and commercial value"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

Although pollinationhas been shown to increase crop quality, a possible impact on shelf life has not been quantitatively studied.Results: We tested how shelf life, represented by fruit decay, firmness and weight, changes as a function of pollinationlimitation in two European, commercially important strawberry varieties. Pollination limitation resulted in lower amountsof deformed fruits. Whereas 65% of wind-pollinated fruits were deformed, open pollination resulted in only 20% deformedfruits. During storage, the proportion of decayed fruits increased in relation to the degree of deformation. In the varietyYamaska, 80% of the fruits with high degrees of deformation decayed after four days, whereas in the variety Sonata, allhighly deformed fruits had already decayed after three days. Fruit weight decreased independent from thedegree of deformation. However, strongest deformations resulted in a generally lower fruit weight in Sonata,whereas in Yamaska, also medium deformed fruits had a lower weight than highly deformed fruits. Effects ofdeformation on firmness declines were mostly variety dependent. Whereas firmness declined similarly for alldegrees of deformation for Yamaska, highly deformed fruits lost firmness fastest in Sonata.Conclusions: Our results suggest that crop pollination has the potential to reduce food loss and waste inpollinated crops and thus to contribute to global food security. However, this relationship between pollinationand food waste has so far been almost completely ignored. Future pollination research should therefore focusnot only on yield effects but also on crop quality. A more comprehensive understanding of how pollinationcan benefit global food security should lead to a more efficient crop production to help meeting future fooddemands."],["dc.identifier.doi","10.1186/2048-7010-3-14"],["dc.identifier.gro","3150120"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10986"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6849"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.relation.issn","2048-7010"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject","Decay, Deformation, Food loss, Food waste, Fruit quality, Pollination limitation"],["dc.title","Enhancing crop shelf life with pollination"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Volatile compounds emitted by crop flowers mediate plant-pollinator interactions, but differences between crop varieties are still little explored. We investigated whether the visitation of crop flowers is determined by variety-specific flower volatiles using strawberry varieties (Fragaria x ananassa Duchesne) and how this affects the pollination services of the wild bee Osmia bicornis L. Flower volatile compounds of three strawberry varieties were measured via headspace collection. Gas chromatography showed that the three strawberry varieties produced the same volatile compounds but with quantitative differences of the total amount of volatiles and between distinct compounds. Electroantennographic recordings showed that inexperienced females of Osmia bicornis had higher antennal responses to all volatile compounds than to controls of air and paraffin oil, however responses differed between compounds. The variety Sonata was found to emit a total higher level of volatiles and also higher levels of most of the compounds that evoked antennal responses compared with the other varieties Honeoye and Darselect. Sonata also received more flower visits from Osmia bicornis females under field conditions, compared with Honeoye. Our results suggest that differences in the emission of flower volatile compounds among strawberry varieties mediate their attractiveness to females of Osmia bicornis. Since quality and quantity of marketable fruits depend on optimal pollination, a better understanding of the role of flower volatiles in crop production is required and should be considered more closely in crop-variety breeding."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2013"],["dc.identifier.doi","10.1371/journal.pone.0072724"],["dc.identifier.gro","3149892"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/9228"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6601"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","Flower Volatiles, Crop Varieties and Bee Responses"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
