he position of a corn plant's growing point region is crucial relative to the plant's susceptibility to above-ground damage. Initially, the growing point is located near the crown of a young seedling. At about leaf stage V4 (four visible leaf collars), stalk elongation begins and the position of the growing point elevates rather quickly over a very few number of leaf stages. This photo gallery illustrates the change in the position of the growing point relative to the leaf stage of a corn plant.
