I get a kick out of these studies being used for propaganda. Plants change to their environment, always have and always will. A mustard plant matures early? It’s called heat units and this always changes. You pick up a bag of seeds and it says 60 days to maturity but if you have warmer days at that particular time it might be 50 days or 70 days if you have cooler days. In my lifetime we have had 3 severe droughts in our area and these began in 1950. Our crops behave differently every year from when we put the first seed in the ground till we finish harvest. Sheesh I hope they are not actually paying these people for their studies when all they have to do is go over to their closest farm and ask how plants behave under different conditions. You might even get a cold glass of tea if it’s hot that day or steaming cup of coffee if it’s cold. Yeah you got it, even that old farmer has learned to adapt to make themselves comfortable under ever changing conditions.
