The Anatomical Study of Leaves Infected with Sooty Mold on Various Plants

Abstrak

Sooty mold is a parasitic fungus that attacks plants. Sooty mold has
black mycelium that spreads and covers the surface of leaves, forming
black spots. These black spots then merge, thicken, and spread to cover
the entire surface of the leaves. The purpose of this study was to
determine the anatomy of leaves infected with sooty mold on various
plants. This study used a descriptive observational research method.
The research was conducted at the Microbiology Laboratory,
Department of Biology, Faculty of Mathematics and Natural Sciences,
State University of Malang. The results of observing the anatomical
structure of leaf tissue infected by sooty mold on various plants
through cross-sectioning showed that the anatomy of the leaves of the
sawo kecik and mango plants indicated that the hyphae only penetrated
the upper epidermal tissue, while in coffee plants, the hyphae
penetrated the upper epidermal tissue, palisade tissue, spongy tissue,
and lower epidermal tissue.
