Stem Splitting in Canola

Ask an ExpertCategory: QuestionsStem Splitting in Canola
superadmin asked 45 years ago

We have a lot of canola with split stems as per the photo. I assume this is from the heavy frosts. The plants appear very healthy with no setbacks from the splitting. Are there any longer term implications? Young NSW

Answer from Steve Marcroft, Marcroft Grains Pathology
We see this symptom most years in isolated situations. There has been no research done to determine the cause.However plenty of anecdotal evidence suggests that it is not due to frost. It is probably due to the canola plants coming out of cold winter conditions and then experiencing the first warm days. The plants grow so quickly as a response to warm weather that the growth is too fast for the plant structure, causing the stem to split.
