Smart solutions for fruit growers
Abstract [en]
Purpose and goal: The overall goals of the project are: to understand how environmental conditions in the orchard govern the postharvest quality of fruits, and thereby develop smart information technology (IT) solutions for apple growers, to create a knowledge base in Sweden through the movement of Ms Bui from Belgium to the University of Gävle and for Ms. Bui to receive a PhD degree. The goals for the planning period were to set up the necessary national and international collaborations, in order to prepare of a full-scale proposal. The goals were fulfilled and a full proposal was submitted on Sept. 16th. Expected results and effects: During the planning period, all travels were made to prospective partners according to plan, in order to set up a tight-knit collaboration, involving public and private sectors in Sweden and in Belgium. Key players with key roles and competence were identified and tied to the project. A detailed plan for the research project and for Ms. Bui´s accomplishment of a PhD degree were developed and finalised. The expected outcome from the planning period was the preparation of a full-scale proposal, covering three years of research, and this was accomplished on time. Approach and implementation: The planning period of 2 ½ months were dedicated to travelling to prospective partners, planning their roles, inviting additional end users into the project and discussions on how to realize the project goals. By meeting the partners and getting to know the reality of their situation, it was possible to select the most suitable ones, who have mutual interest in the project. They are willing to offer materials, weather data, their time and expertise to the project. The hosting university and apple growers also expressed active interest, and everyone is looking forward to this cooperation.

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.
