Web1. Vegetative reproduction: The most common method of vegetative reproduction is fragmentation. The hypha breaks up into small fragments accidentally or otherwise. Each fragment develops into a new individual. In the laboratory the ‘hyphal tip method’ is commonly used for inoculation of saprophytic fungus. WebEven among fungi that reproduce both sexually and asexually, often only one method of reproduction can be observed at a specific point in time or under specific conditions. Additionally, fungi typically grow in mixed colonies and sporulate amongst each other. These facts have made it very difficult to link the various states of the same fungus.

WebHow does Aspergillus grow and reproduce? For most part, they reproduce asexually through the production of spores known as conidium (fungi spore). Once the spore lands on a favorable environment (with moisture, warmth and nutrients) they start germinating where they create numerous hyphae that form the mycelium.
