Definition of phyllotaxis in English:
phyllotaxis
(also phyllotaxy)
noun ˌfɪlə(ʊ)ˈtaksɪsˌfɪləˈtæksəs
mass nounBotany The arrangement of leaves on an axis or stem.
〔植〕叶序
Example sentencesExamples
- The courses of these bundles were presented both in transverse sections chosen at characteristic points (where changes in phyllotaxy and bifurcation of leaf trace bundles occurred) and in longitudinal diagrams.
- From this and related work it has become necessary to define a meristem by its phyllotaxy and other growth patterns and not the identity of organs it produces.
- Poaceae species present a conserved distichous phyllotaxy (leaf position along the stem) and share common properties with respect to leaf initiation.
- There was a negative correlation between phyllotaxy and leaf primordium diameter: species with greater numbers of orthostichies or parastichies had smaller leaf primordia.
- Each current-year shoot of Q. crispula has one terminal bud, one to five terminally lateral buds and several lateral buds in the lower stem in alternate phyllotaxis.
Derivatives
adjective
Botany Although the direction of phyllotaxis appears to be random in many plants, there is some evidence for a genotypic component of consistent phyllotactic bias in some species of Tifolieae.
Example sentencesExamples
- Counting ribs and phyllotactic spirals was easy and accurate, so that should have introduced little error.
- For example, in the case of sho mutants, the predominance of a distichous phyllotactic pattern is not recognizable by visual observation of the schematic alignment of primordia.
- It is interesting to note that there is no discontinuity in the phyllotactic pattern of the flowers between the different zones of the inflorescence.
- The sympodia are arranged more or less parallel to the stem axis and follow the phyllotactic spirals of the leaves.
