Leaf Physiology and Anatomy by Photoacoustics

Second International Meeting on Photoacoustic Spectroscopy, 1981
Plant 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 ...

Leaf Anatomy in Crocus (Iridaceae)

Kew Bulletin, 1990
The 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, 1992
Since 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.

Leaf and Stem Anatomy of Tradescantia fluminensis, Vell.

Journal of the Linnean Society of London, Botany, 1925
Summary. 1The investigation was started in the hopes of throwing some light upon the problem of sap supply to the upper parts of leaves which grow by a basal meristem, but has been extended as a developmental study of the shoot. 1The scattered bundles of the stem may be classified into four groups–(a) medullary, (b) perimedullary, (c) cortical, (d ...

Ontogeny of Leaf Morphology and Anatomy

1985
Because of their role in intercepting and absorbing radiant energy, and transforming it to energy of organic substances through the complex process of photosynthesis, leaves are the most important organs for plant production, and hence for agriculture.

LEAF ANATOMY OF WELWITSCHIA. I. EARLY DEVELOPMENT OF THE LEAF

American Journal of Botany, 1958
MATERIALS AND METHODS.-The material, collected in South-West Africa or grown in Berkeley, California, is the same as that used in the seedling study (Rodin, 1953b) and the same techniques have been applied. Approximately 24 seedlings were used in this investigation.

Systematic Descriptions Of Leaf Anatomy

1995
Abstract This subfamily consists of a single monotypic rhizomatous genus from the mountains of Tasmania, with unifacial evergreen leaves. The dark purple flowers (Fig. lE) are solitary and the inflorescence is a single-flowered rhipidium (Goldblatt 1990). It is previously little-known anatomically, except from Rudall (1986). Since it has
