3 inflorescence detectable stage

From BugSigDB

A reproductive growth stage during which an inflorescence is detectable.nnThis includes the stage when an inflorescence starts to develop (and is detectable only by assay or with a microscope), to the stage where it is visible to the naked eye. This includes the booting stage in the grasses (Poaceae). There is no one-to-one correspondence between some of the phases of inflorescence formation in members of Poaceae (e.g., booting) with that of other families.
