- In a recent publication, Edelmann  (Protoplasma 2018; 255,1877–1881) refuted the well-established starch-amyloplast hypothesis of gravitropism in plants. Gravitropic curvatures of shoot and roots were still present after amyloplast-containing tissues (in sheath of vascular bundles and root caps) were dissected. Here, we discuss Edelmann’s data in the light of Popper’s falsification principle.
