Physiology and Pathology of Post-harvest Crops

Physiology and Pathology of Post-harvest Crops
  • Course number: 0411-3156 
  • Dates: July 2th - July 7th 2022 (9:00 - 15:30) 
  • Location: Will be determined
  • Course credits: 2 credits
  • A final written exam will be conducted at the end of the course. 
  • The course is taught is English
  • Biology/ Agricultural/ Biotechnology background is mandatory for registration



The aim of the course is to allow you to understand the physiological and pathological aspects related to quality maintenance of harvested produce after storage and how to extend storability and shelf life of the fresh produce.

You will have a chance to learn about the physiological and molecular processes of ripening and aging, which occur during fruit and vegetable's growth, and about the post-harvest decay, caused by pathogens and the molecular basis of their pathogenic mechanisms.

To prevent produce loss, you will learn about mechanisms for treating fresh produce to prevent damage by pathogens and by physical and environmental factors.
