Effect of cooler temperatures on canola

Cooler overnight temperatures (in the neighborhood) of 1 to 2 C occurred overnight Monday into Tuesday in parts of Alberta. These cooler temperatures will not affect canola crops significantly. Growth chamber research shows that seed enzyme effects could be impeded with temperatures at 1 C which resulted in higher green seed. Any impact these low temperatures may have in field conditions will be insignificant and no management decisions should be based on these temperatures. Lowest temperatures tend to occur in low lying areas which are often the areas with highest production. This year is an exception since many low lying areas are the areas with poorest production.
