Manifestations of Deficiency in Microelements for Roses
1. Nitrogen Deficiency
It first manifests as a uniform chlorosis in the older leaves, slow plant growth, yellowing leaf color, and in severe cases, leaf shedding. Chlorosis symptoms always start from the older leaves and then develop to the younger leaves.
2. Phosphorus Deficiency
It first manifests in the older leaves. When roses lack phosphorus, the leaves appear abnormally dark green, sometimes with gray or purple spots. The older leaves turn slightly blue with a purple hue, the leaf edges become purplish-red, and the leaf tips die.
3. Potassium Deficiency
Potassium deficiency first manifests in the older leaves. In dicotyledonous plants, the leaves show mottled chlorosis areas, followed by necrotic areas along the leaf edges and tips, leaf curling, and eventually blackening and burning. In monocotyledonous plants, the tip and edge cells first die, then spreading downward.
4. Calcium Deficiency
Calcium deficiency symptoms first appear in the younger leaves. Typical symptoms include the necrosis of the tips and edges of young leaves, then the necrosis of leaf buds, and the root tips stop growing, discolor, and die. The plant becomes dwarfed with dark green crinkled leaves. Leaf margins show spotted patterns.
5. Magnesium Deficiency
Magnesium deficiency symptoms usually occur in the older leaves. Typical symptoms include interveinal chlorosis and spots. Sometimes there may be bright red or orange colors, and in severe cases, small areas of necrosis.
6. Sulfur Deficiency
Sulfur deficiency symptoms are similar to nitrogen deficiency, such as uniform chlorosis and yellowing of the leaves, and growth inhibition. However, sulfur deficiency usually starts from the seedlings.
7. Iron Deficiency
Iron deficiency first manifests in the younger leaves, with typical symptoms of distinct interveinal chlorosis, which can become scorched in severe cases.
8. Zinc Deficiency
The typical symptom of zinc deficiency is the inhibition of internode growth, with severe leaf deformation. Linear color spots on leaves and chlorosis in older leaves are also common symptoms of zinc deficiency.
9. Boron Deficiency
The typical symptom of boron deficiency is thickened leaves and darkened leaf color, with the terminal meristematic tissue of branches and roots dying.
10. Manganese Deficiency
Manganese deficiency causes leaf chlorosis and small necrotic spots on the leaves, which can occur in both young and old leaves. Be careful to distinguish it from bacterial spot diseases and brown spot diseases.
11. Copper Deficiency
Symptoms first appear in the younger leaves. Leaf tip necrosis and leaf withering turn black.
12. Molybdenum Deficiency
Initial symptoms include interveinal chlorosis and necrosis in the older leaves, sometimes with spotted necrosis.
13. Chlorine Deficiency
The leaves first wilt, then show chlorosis and necrosis, and finally turn bronze in color.
Manifestations of Deficiency in Various Microelements
