Tissue desiccation is considered to be involved in anther opening, and it is agreed that environmental humidity affects its timing. Different sources of evidence suggest that the later steps of the process (i.e. stomium opening and outward wall bending) are regulated in different ways. Anther opening was studied in Allium triquetrum under four regimes of relative humidity (RH) to analyse the effect of this parameter and to speculate about its possible regulation.
