The peduncle was strengthened by cell wall thickening via cellulose deposition and vascular bundles lignification for mechanical support.
The peduncle contains the ovaries and some musculature; it may or may not be armoured by calcareous plates, as in Pollicipes and Lepas, respectively.
The peduncle is the main stalk, connecting the rachis with the stem.
The peduncle of the female organ pair, rarely seen, was about 0.5 mm long (Fig. 2a).
The peduncle and the AZ are mainly made up of this type of cells.
The peduncle continued to grow at a mean rate of about 14 mm d-1 until the eighth day after anthesis.
The peduncle, which is located at the first internode directly below the spike, has a diversity of critical roles in crop productivity.
The principle resemblances are the partially tubulated center and the peduncle of the flowers as mentioned in the type description.
At the time of flowering, the apical meristem (the terminal point of cell division) produces a flower bud, thus arresting the growth of the peduncle.
"They're pretty hardy until they get to the peduncle elongation stage, which is what we're heading into this weekend," he said.
In order to beat in unison, each pair is usually hooked together by spines on the inner margin of the peduncle (retinacula) or the inner ramus ("clothespin spines").
