Title [en]
Smart solutions for fruit growers
Abstract [sv]
Syfte och mål: Projektet, “Smarta lösningar för fruktodlare” har gjort svenska fruktodlare mer konkurrens-kraftiga. Nu kan man förutsäga odlingsförhållanden, som leder till frukt av högre kvalitet. Tuyet Bui har överfört kunskap och resultat från ett projekt i Belgien, som utvecklas med nya ansatser för äpplen. Hon har koordinerat projektet och arbetat med att överföra kunskap till kooperativet ’Äppelriket’ och ett svenskt företag, ’In Situ’. Hon har också överfört kunskap till Sverige vad gäller att utveckla smart informationsteknologi (IT) under tre år som VINNMER-stipendiat. Förväntade effekter och resultat: Projektet baseras på en 4-årig belgisk studie, där Tuyet Bui (projektledare) fann att kvalite’n hos äpplen efter skörd var en följd av hur de odlats. Sol, regn och balansen i markfukt liksom kvalite’n på jorden är de viktigaste faktorerna för äpplenas kvalite’. Av erhållna data skapas modeller, som skall tillåta fruktodlare att dels förutsäga fruktens kvalite’, dels fatta beslut om skörd, baserade på fruktodlingens klimat. Dessa verktyg kommer att göra svenska fruktodlare mera konkurrenskraftiga. Vid slutet av projektet kommer Tuyet Bui att erhålla sin doktors-examen. Upplägg och genomförande: En kunskapsbas har skapats i Sverige genom Tuyet Buis flytt från Belgien till Gävle högskola. Hon har undersökt äpplens resistens mot gråmögel och använt äpplen från odlingar i Skåne med olika lokalklimat. Ett svenskt företag (In Situ) och äppelodlarkooperativet Äppelriket deltar. Forskningsgrupper vid K.U. Leuven har understött med expertis vad gäller lagring efter skörd och biologi och In Situ har försett Tuyet Bui med väderdata. Långsiktigt mål för Tuyet Bui är att dels utveckla mycket bra kunskap och know-how i sitt yrke dels att bygga ett starkt kontaktnät i Sverige och Belgien.
Abstract [en]
Purpose and goal: The project, “Smart solutions for fruit growers” made Swedish fruit growers more competitive by giving access to models that leading to high quality fruit. Ms. Tuyet Bui applied the knowledge and results of at previous project in Belgium to the conditions in Sweden. She coordinated the project, served to bridge the knowledge gap between the growers’ cooperative (Äppelriket) and a small Swedish enterprise (In Situ). She transferred the knowledge from Belgium to Sweden and provides a foundation for developing smart information technology (IT) during the three years as a VINNMER Fellow. Expected results and effects: The project, in which Ms. Bui is the Project Leader, built on her knowledge and results from a previous 4-year project in Belgium. Her research demonstrated that sun, rain and the balance in soil moisture are the most important weather factors for apple quality. Soil quality in the orchard affects the quality of the apples, since fruit from different orchards vary in quality. The data is used to generate models enabling fruit growers to predict fruit quality and make harvest decisions, based on the climate at the orchard. At the end of the project, Ms. Bui is close to obtain her PhD degree. Approach and implementation: The knowledge base in Sweden was created through the mobility of Ms Bui from Belgium to the Univ. of Gävle. Ms. Bui tested apples from Swedish orchards with different local climates in Skåne for resistance to grey mould and collected weather data from those orchards. A small Swedish enterprise and the growers’ cooperative are participating in the project. Research groups at K.U. Leuven supported with expert experience in postharvest knowledge and biology. In Situ provided Ms. Bui with knowledge of weather station. The long-term aim is to extend the models to other pathogens for apples.

Abstract [en]

BACKGROUND: The fruit of two apple cultivars - 'Braeburn', which is susceptible to inoculation with Botrytis cinerea, and the less susceptible cv. 'Golden Delicious' - were investigated with respect to their response to inoculation with B. cinerea. Successful infection by B. cinerea leads to an oxidative burst and perturbation of plant redox homeostasis. To investigate the interaction between apple fruit and B. cinerea, antioxidant metabolism in fruit samples from sun-exposed and shaded sides of different tissue types was measured over time.

RESULTS: The sun-exposed tissue of 'Braeburn' had higher initial levels of total vitamin C in the peel and phenolic compounds in the flesh than 'Golden Delicious', despite its greater susceptibility to gray mold. A substantial antioxidant response was recorded in diseased 'Braeburn' fruit 14 days after inoculation, which involved an elevated superoxide dismutase activity and ascorbate peroxidase activity, a progressive oxidation of total vitamin C, and a decrease in peroxidase activity and phenolic content. Disease development was slower on the sun-exposed sides than on the shaded sides.

CONCLUSION: The two cultivars appeared to utilize different strategies to defend themselves against B. cinerea. 'Golden Delicious' almost entirely escaped infection. Preharvest exposure of apple fruit to high light / temperature stress appears to prepare them to better resist subsequent postharvest attack and disease.
