Four photo questions on interesting things found while scouting canola crops across the Prairies this week.

2. Look closely. See the cotyledon unfolding from these green seeds. What causes "precocious germination"?

Excess heat

Re-wetting of pods

All three, maybe more

3. What is on these pods?

Ash from Eyjafjallajökull
