Abstract

Blueberries contain components like for instance triterpenes and stilbenes which have potentially protective roles against many human diseases. These substances are also important at threats from herbivores and fungi attacks to plants. Quality traits assessed in this study was the amount of healthy substances like triterpenes, stilbenes, but also sugar/acid ratio which are important for flavor.

In this work it was investigated if mycorrhiza inoculations on blueberry plants can increase the quality of the berries. Quality trait that was studied was the triterpenes ursolic acid and oleanolic acid, the stilbene pterostilbene and sugar/acid ratio of the blueberries. The result showed that ursolic acid, oleanolic acid and sugar/acid ratio was dependent on the variety of blueberry and not the mycorrhiza inoculation. Pterostilbene was not possible to detect with the methods that was used.

Blåbär innehåller ämnen som till exempel triterpener och stilbener som hjälper till att förebygga många humansjukdomar. Dessa ämnen är även viktiga vid hot från växtätare och svampangrepp mot växter. Kvalitetaspekter som bedömdes i denna studie var mängd hälsosamma ämnen som triterpener och stilbener, men även socker/syra-innehåll som är viktigt för smaken.

I detta arbete undersöktes om mykorrhiza-ympning på blåbärsplantor kan öka kvaliteten på bären. Kvalitetegenskaper som studerades var triterpenerna ursolic acid och oleanolic acid, stilbenen pterostilbene och socker/syra innehåll i blåbären. Resultatet visade på att mängd ursolic acid, oleanolic acid och socker/syra-innehåll beror på blåbärssort och inte mykorrhiza-ympningen. Pterostilbene var inte möjligt att detektera med de använda metoderna.
