Solution(By Examveda Team)

The uredospores of Puccinia graminis are disseminated by Wind.
The uredosorus develops on the wheat plant from the dikaryotic mycelium produced by germination of aeciospore, which comes from barberry plant generally through wind dissemination.
They are dispersed by wind and germinate on leaf surfaces under humid conditions when the stomata are likely to be open.
