Back on April 15, we had a freeze that killed emerging pecan buds on the lower portions of tree canopies. As the spring flowering season arrived, I noticed that primary buds at the base of frost damaged shoots emerged to produce pistillate flower clusters. Today, I used our hydraulic lift to check nut development of Pawnee trees that had suffered cold injury on the lower portions of their canopies.
Come this fall, I wonder if I will time of shuck split will differ with tree height. I bet it will.
