In my doctoral research, i'm investigating the intersection of biotechnology and maize seed (Zea mays) productivity. An intriguing observation I have made pertains to the coloration of maize seed roots, which exhibit a purplish-pink hue after seven days post-sowing. As coloration often serves as an indicator of the plant's physiological state, i'm keen to elucidate the underlying factors contributing to this phenomenon. It's noteworthy the affected roots do not exhibit typical signs of disease or contamination.
Despite thorough scrutiny of plant biology literature in both print and online formats, I have yet to discover definitive explanations for this phenomenon. I am therefore reaching out for assistance in this matter. Your expertise or any relevant insights you can provide would be greatly appreciated.
Purple maize roots likely indicate anthocyanin production, a pigment triggered by stress like cold or nutrient deficiency. It's usually not a major concern for healthy plants.
I agree, looks like anthocyanin. If you get some purple/red seeds and try those ones they will probably show even more root coloration. Light can also lead to anthocyanin accumulation.
Hello
The purple color is mainly seen in the crown part of the corn plant, but the lack of phosphorus is the obvious reason for the purple color in the crown and leaves of corn. But I have not seen this color in the roots.
The roots are also purple. In the upper part near the seeds it is possible to see the purple color. My hypothesis at the moment is that the lack of light is influencing the production of anthocyanins.
