Which of the following is NOT a common phytotoxicity sign in seedlings?

Explanation:
Phytotoxicity signs in seedlings are indicators of damage from chemicals or stress. Leaf scorch shows tissue death at the leaf margins or tips, a common injury pattern from toxic exposure. Bleaching reflects loss of pigment, leaving pale or white patches where chlorophyll is degraded. Necrosis is dead tissue, visible as brown or black lesions. Growth enhancement, on the other hand, would imply increased growth or vigor, which is not a sign of damaging phytotoxicity. In seedling assessments, you look for injury symptoms, not stimulation of growth, so growth enhancement is not a typical phytotoxicity sign.
