In all these species, the broad arcuate viscidium firmly embraces the pollinator scutellum when the insect leaves the flower. |
The embryogenetic process allows the formation of a well-differentiated embryonic axis, surrounded by a single massive cotyledon, the scutellum. |
This reward-lacking orchid is pollinated either by workers or drones of Apis cerana japonica which fix pollinaria on the scutellum. |
The ENGase activity was almost equally distributed in the endosperm, the radicle and the scutellum. |
An aspartic proteinase was also found in the PB of scutellum cells in dry barley grains. |
Then, the arcuate viscidium firmly embraces and adheres on the bee scutellum and the pollinarium is removed. |
