The phenomenon of “pepper seedlings turning purple” refers to a physiological change in the young plants wherein their foliage exhibits a purplish or reddish-purple coloration. This often occurs under specific environmental conditions, such as excessive sunlight, extreme temperatures, or nutrient deficiencies. Understanding the causes and implications of pepper seedlings turning purple is crucial for gardeners and agriculturalists. It can help prevent stunted growth, reduce crop yield, and ensure the overall health and vitality of pepper plants. Historically, research on the impact of environmental stress on pepper seedling pigmentation has provided valuable insights into plant biology and cultivation techniques.
