Curing of tea levels is brought about by the activity of bacteria. It is essentially an oxidation dry fermentation process, during which, water is driven off, the green colour is lost and the leaves assume a tougher texture and undergo chemical changes.
Mycorrhiza is a mutually beneficial association between fungi and the roots of higher plants. Viruses and fungi are not involved in the curing process of tea leaves.
