A Biochemical Test for Low Seedling Vigor in Canola

Researcher:

Dr. Wayne T. Buckley, Agriculture and Agri-Food Canada, Brandon MB

Project Code:

CARP 2000-16

Final Report:

October 2003

Summary:

Seed deterioration is the major cause of poor vigor in canola seedlings, which can reduce seedling emergence, crop establishment and yield. After studying the biochemistry of canola seed, researchers have developed two 24-hour vigor assays based on ethyl alcohol emission by canola seed that can reliably detect deterioration of canola seed. Vigorcheck is an on-farm colour test, while Vigorscore is an instrumental technique suitable for use by agri-business.
