Anther dehiscence in two‐rowed barley (Hordeum distichum) triggered by mechanical stimulation

Pricking or pressing an ovary can induce anther dehiscence in cleistogamous two‐rowed barley in the absence of lodicule swelling. This response is considered to be inherited from a chasmogamous ancestor in which anther dehiscence is induced by the stimulus given to the pistil by the lodicule swellin...

Description
Summary:Pricking or pressing an ovary can induce anther dehiscence in cleistogamous two‐rowed barley in the absence of lodicule swelling. This response is considered to be inherited from a chasmogamous ancestor in which anther dehiscence is induced by the stimulus given to the pistil by the lodicule swelling, which causes floret opening.
