Studies on perithecium of Ceratocystis stenoceras by a scanning electron microscope

Area of Science:

• Mycology
• Plant Pathology
• Scanning Electron Microscopy

Background:

• Ceratocystis stenoceras is a fungal pathogen.
• Understanding fungal morphology is crucial for disease management.

Purpose of the Study:

• To investigate the surface and internal morphology of Ceratocystis stenoceras perithecia.
• To provide detailed ultrastructural insights using scanning electron microscopy.

Main Methods:

• Scanning electron microscopy (SEM) was employed.
• Perithecia of Ceratocystis stenoceras were examined.

Main Results:

• Perithecia exhibited a spherical body (96-231 µm) covered in hyphae.
• The neck was a hollow cylinder with a hyphal wall, featuring a rough base and smooth, patterned upper section.
• Ascospores within the cavity were orange-segment-like (1x2 µm) with smooth surfaces.

Conclusions:

• SEM provides high-resolution detail of Ceratocystis stenoceras perithecial structures.
• Morphological characteristics offer potential taxonomic and diagnostic value.
