American Journal of Botany, 1934
Ash. In Fraxinus peunsylvanica Marshall the essential structure of the embryonic leaf is revealed by a study of an unswollen leaf bu-id of late March. Each leaflet (fig. I, 2) consists of midrib and conduplicately folded wings. The wings are composed of a limiting layer of small, brick-shaped cells and a mesophyll region of cells of somewhat similar ...

Botanical Journal of the Linnean Society, 1975
A study of leaf anatomy of 24 genera of Cunoniaceae was made. The prevailing petiole vasculature is a nearly complete, usually adaxially flattened, medullated cylinder with the flat dorsal segment separated from the ventral arc. Medullary and cortical vasculation in Codia, Cunonia, Geissois and Pancheria is correlated with an increase in leaf ...

Physiologia Plantarum : An International Journal for Plant Biology, 2021
Mesophyll conductance (gm ), a key limitation to photosynthesis, is strongly driven by leaf anatomy, which is in turn influenced by environmental growth conditions and ontogeny.

Physiologia Plantarum : An International Journal for Plant Biology, 2018
Mesophyll conductance to CO2 (gm ), a key photosynthetic trait, is strongly constrained by leaf anatomy. Leaf anatomical parameters such as cell wall thickness and chloroplast area exposed to the mesophyll intercellular airspace have been demonstrated to

Leaf anatomy in the Tecophilaeaceae
Botanical Journal of the Linnean Society, 1986ARROYO, S., 1986.Leaf anatomy in the Tecophilaeaceae. Leaf anatomy of 12 species of the seven genera in the Tecophilaeaceae is described. Characters of taxonomic value within the family are the shape of epidermal cells, hairs and venation. Characters of diagnostic importance at the family level include the occurrence of raphide sacs in the mesophyll ...

Leaf Physiology and Anatomy by Photoacoustics
Second International Meeting on Photoacoustic Spectroscopy, 1981Plant leaves are generally composed of about seven to eight layers of cells: an upper epidermis layer, two to three layers of elongated palisade cells, about three layers of spongy cells with large intercellular air spaces and a lower spidermis. The epidermis layers contain pores (stomata) with a mechanism to open or close them, controlled by adjacent ...

Anatomy of Leaf Classification Techniques
2019 International Conference on Machine Learning, Big Data, Cloud and Parallel Computing (COMITCon), 2019There are number of categories of flora and fauna on earth. Vegetation is important for the existence of life. Leafs are the essential part of this vegetation. It is important to recognize them so that we can preserve them for the future. Classification is a process to distinguish the leaf on the basis of features that are extracted from the leaf ...

Leaf Anatomy in Crocus (Iridaceae)
Kew Bulletin, 1990The leaf anatomy of Crocus L. (Iridaceae-Ixioideae) is described in the context of the systematics of the subfamily. Leaves of most species have a distinctive cross-sectional outline, with a central square or rectangular 'keel', and two lateral 'arms'. C. carpetanus differs markedly in that it lacks a single central keel, and has several surface ridges.

Anatomy of non-uniform leaf photosynthesis
Photosynthesis Research, 1992Since 1986, non-uniform photosynthesis over the leaf area that may be attributed to patchy stomatal closure, has been an important issue in stress physiology of photosynthesis. In this review, I first outline the gaseous environment within the intercellular spaces, because this is the most fundamental background of this problem.
