plant pathology
Quick Summary
Macroscopic symptoms in plant pathology are visible signs of disease that can be observed without magnification. These symptoms are categorized into four main types: prenecrotic, necrotic, hypoplastic, and hyperplastic or hypertrophic. These categories describe the abnormal effects on plant cells, tissues, and organs.1
- Prenecrotic symptoms are early indicators of cell death.
- Necrotic symptoms involve the death of plant tissues, appearing as spots, blights, or scorch marks.12
- Hypoplastic symptoms result in underdeveloped plant parts, leading to reduced size or dwarfing.
- Hyperplastic or hypertrophic symptoms cause abnormal overgrowth or enlargement of plant tissues, such as galls or cankers.1
Diagnosis of plant diseases relies on observing these symptoms, alongside identifying the pathogen responsible.123
