I found this explanation on Wikipedia to be most informative:
The effect of wind chill is to increase the rate of heat loss and reduce
any warmer objects to the ambient temperature more quickly. Dry air cannot,
however, reduce the temperature of these objects below the ambient
temperature, no
Hi Art
Plants respond to ambient temperature and unlike warm blooded animals do
not create their own. So wind chill does not affect them. Wind x
temperature could have an effect on moisture relations within the plant,
but I think that is not a major issue. At least that's my understanding of
Does anyone have a handle on how wind chill relates to fruit bud critical
temps. We are expecting -11F tonight with a wind chill effect of around
-30 F.

So far as I know, wind chill is pretty much irrelevant when it comes to plants
and other life forms that are not warm-blooded creatures. Wind-chilll provides
an estimate of how we perceive the cold, but the measured temperature on the
thermometer is still the temperature experienced by trees.
