Physiological Fruit Disorders: Blossom-End Rot
| [Image: Click here to view larger image.] |
A localized calcium (Ca) deficiency in the distal end of the fruit results in blossom-end rot. Fruit and undeveloped leaves have low transpiration rates and, therefore, are subject to this physiological disorder. Because calcium is not a highly mobile element, deficiency can occur with water supply fluctuations, high salt levels, the use of ammonium nitrogen and moisture extremes. Both blossom-end rot and sunscald are physiological disorders that cannot spread from plant to plant. |
