The deficiency of manganese in plants results in?
death of shoot
leaves turning yellow
stunted growth
poor root development
설명
Manganese deficiency can be easy to spot in plants because, much like Magnesium deficiency (agriculture), the leaves start to turn yellow and undergo interveinal chlorosis. The difference between these two is that the younger leaves near the top of the plant show symptoms first because manganese is not mobile while in magnesium deficiency show symptoms in older leaves near the bottom of the plant.
