I know that heat effects canola during flowering - most of my crop had the top third blasted off. However, does heat effect its ability to fill the pods that are there? We have reasonable moisture but it looks like another hot week coming up...

The hotter the weather during filling the lower the tkw. Also if It gets hot enough to where the plant is loosing more moisture to evaporation than the root / vascular system can replace the pods will start to shrivel starting at the very top... this produces the "salt and pepper" seed that has no oil and is shriveled and a darkish red color.

If there's good moisture it should be ok unless it's prolonged very hot.

Define what you mean by 'heat' ?

 

[rook]

thanks for the replies. By heat, I mean 30C.

Thought at first you meant HEAT the Chem.

One thing I would watch is kernel size and broken kernels at harvest and on the grading bench.
Size of slotted sieve when assessing conspicuous admix may have to be smaller elevators tend to use .038 or .040 on all samples where they maybe should be using .028 or .032 depending on consp admx.

If leaves are cool it's drawing ground water if not then evapo transpiration rate is winning

You can't simply take temp in isolation, but this may help answer your question:
