Deficiency of Potassium
The major mineral in plants is potassium, and both high and low levels of potassium have been associated with abnormal metabolism. High potassium (and also magnesium) and low calcium has been associated with the development of bitter pit in apple.
Low potassium delays the development of full red colour by inhibiting lycopene biosynthesis in tomato. |
