Root sclereids ofSyzygium cumini (L.) Skeels [PDF]

open access: yes, 1972
Sclereids in the roots ofSyzygium cumini (L.) Skeels (Myrtaceae) are polymorphic. In addition to the brachy-, osteo- and bizarre sclereids, there occur an interesting kind of sclereids—the fibre sclereids—resembling the fibres in some respects ...

Metodologia para determinação da zona de abscisão foliar em pomáceas. [PDF]

open access: yes, 2019
Estudos anatômicos e de ontogênese da abscisão foliar em pomáceas são escassos. A queda foliar promovida após formada a zona de abscisão é um processo natural nas pomáceas, e prolonga-se durante o outono, até que ocorram as primeiras geadas no Sul do ...

Stem anatomy and ontogeny of vascular variants in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
An increase in stem thickness and ontogeny of successive cambia, intraxylary cambium, and inter‐and intraxylary phloem is elaborated for the first time in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae). As the plants grew older, several small segments of cambium were initiated simultaneously external to the phloem formed by regular ...

Plasticity in dendroclimatic response across the distribution range of Aleppo pine (Pinus halepensis) [PDF]

open access: yes, 2013
We investigated the variability of the climate-growth relationship of Aleppo pine across its distribution range in the Mediterranean Basin. We constructed a network of tree-ring index chronologies from 63 sites across the region.

Temporal variations in peridermal skin development between five kiwifruit (Actinidia chinensis) selections

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 53, Issue 5, Page 3049-3065, December 2025.
ABSTRACT The fruit skin provides a barrier to the developing tissues within. In some fruit, such as the dead‐skinned varieties of kiwifruit, the skin layer develops over time. Observations in kiwifruit orchards suggest that different selectionss have different susceptibility to skin damage caused by common orchard management spray practices.

Metamorphosis differences of caudiciform plants as an adaptation to arid conditions [PDF]

open access: yes, 2023
In the course of evolution, the formation of succulent variations in the underground and surface parts of plants in different taxa could occur simultaneously under the influence of similar abiotic factors, in particular as an adaptation to arid ...

An updated history of TDIF‐PXY signalling: a study in cell fate and tissue patterning

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1154-1165, November 2025.
Summary Non‐cell autonomous signalling is a mechanism by which stem cells are maintained across the tree of life. In plants, many stem cell populations are regulated by peptide ligands related to CLAVATA3, which are secreted from one cell type and bind to the leucine‐rich repeat domain of a plasma‐membrane‐localised receptor kinase related to CLAVATA1 ...
