From: Husk to caryopsis adhesion in barley is influenced by pre- and post-anthesis temperatures through changes in a cuticular cementing layer on the caryopsis

Transmission electron micrographs of husk and caryopsis surface cuticles. a Caryopsis at GS 75 from WC treatment. There is an electron-dense cuticle proper and underlying flocculate cuticular layer (black arrow). b Well-adhered cementing layer at GS 85 from CC treatment. The cementing layer comprises the caryopsis cuticle (black arrow), and the inner cuticle of the husk (black and white arrow). Alternating electron-dense and electron-lucent lamellae are present between the cuticles (white arrow). c Inner surface cuticle of a lemma at GS 45 grown in warm conditions. The interface between the electron-lucent cuticle and cell-wall of the lemma is smooth (black arrow). d Nudinka caryopsis at GS 77. A thin, electron-lucent surface cuticle is present (black arrow). Le = lemma cell wall, Pe = pericarp cell wall
