Example sentencesExamples
- For experiments, Cuscuta shoots of 30-35 cm length were cut from the stock culture and carefully twisted around the stems or petioles of older source leaves.
- The high pressure flow meter was first used to measure the hydraulic conductance of whole shoots and its components, i.e. stems, petioles, and leaf blades in Quercus, Acer, and Populus species.
- Plants were dissected into leaves, stems with petioles, and inflorescences.
- The experimental plants were partitioned into roots, petioles, leaves and stolons.
- Plastid morphogenesis in stalk cells of the two types of trichome from both the stem and leaf petiole is highly variable, and a variety of different plastid morphologies can be observed in the same stalk cell.
Synonyms
stem, shoot, trunk, stock, cane, bine, bent, haulm, straw, reed
2Zoology
A slender stalk between two structures, especially that between the abdomen and thorax of a wasp or ant.

Derivatives

petiolar

adjective ˈpɛtɪəʊləˌpidiˈoʊlər

In the wine grapevine Vitis vinifera ‘Merlot’, poor growth during establishment and variable yields in mature plants grown in many South Australian vineyards is positively correlated with reduced petiolar molybdenum levels.
Example sentencesExamples
- Earlier studies have shown that the retarding effect of low petiolar temperatures on sucrose transport through sugar beet (Beta vulgaris L.) petioles is markedly time-dependent.

petiolate

adjective ˈpɛtɪəʊlət

Perennial scapose herbs with simple stems from short, stocky, horizontal rhizomes bearing a whorl of 3 net-veined, green or mottled, ovate-obovate or elliptical bracts, petiolate or sessile, flower solitary.
Example sentencesExamples
- Lechea mucronata might sometimes be confused with L. minor, which also has petiolate leaves and keeled sepals.
- The basal stems can be confused with those of L. mucronata, but that species has branched basal stems that are prostrate and petiolate basal leaves.
- Several other plants had flowers borne on pedicels about three cm. long and petiolate bracts, the bracts being about as long as the pedicels.

Origin

Mid 18th century: from French pétiole, from Latin petiolus 'little foot, stalk'.
