SUMMARY In tests using pre‐soaked teliospores of Urocystis agropyri , germination was stimulated by tissues from all parts of the host plant (wheat) irrespective of cultivar or resistance to flag smut. Seedling tissues of some non‐hosts (maize, rice, sorghum, cotton, mungbean and groundnut) also stimulated germination. Similar stimulatory effects were achieved by brief exposure to volatiles from wheat seedling tissues, and from the known sources of ethylene, ripening bananas, lemon fruit and ethephon (2‐chloroethyl phosphonic acid) solution. The possibility that ethylene may have a direct triggering effect on teliospore germination is discussed.
