Effects of Asparagus virus 1 (AV-1) on yield and quality components on asparagus

A greenhouse experiment was conducted with three asparagus cultivars to define the impact of Asparagus virus 1 (AV-1). Asparagus plants of ‘Eposs’, ‘Ravel’ and ‘Gijnlim’ were inoculated with AV-1 and compared with virus-free plants regarding yield and quality traits. Yield components such as shoot weight, length, number and root weight were measured. Furthermore the root development was assessed using a digital image analysis system. Quality associated components such as Brix values and volatile organic compounds (VOCs) were additionally examined. AV-1 infection caused significant reduction in root weight of between 31-61%. A decrease of Brix values was observed in shoot and root tissue of infected plants. The ratio of storage root on the total root tissue was reduced by 11%. VOCs of asparagus spears showed significant changes.
