The fact that the corn plants are in the vegetative growth stage of development is the reason for the quick recovery. Last Wednesday a lot of corn was in the V8-V10 stage of growth.
Since we are talking plant physiology we should point out one more thing. Ear shoots are visible in a V10 corn plant. Carefully removing the leaves reveals ear shoot formation occurring at each node. There is one dominant shoot that takes priority over the rest, but the plant prepares for the future by generating 4-5 ear shoots and if the environment allows it then has the ability to produce multiple ears.
So steadfast and true, the corn plant comes to our emotional rescue.
