XYLEM ANATOMY OF SOPHORA (LEGUMINOSAE) IN RELATION TO HABIT

American Journal of Botany, 1962
Cumbie, B. G., and Dan Mertz. (U. Missouri, Columbia.) Xylem anatomy of Sophora (Leguminosae) in relation to habit. Amer. Jour. Bot. 49(1): 33–40. Illus. 1962.—A comparison of 8 tree, shrub, and herbaceous species of Sophora showed considerable variation in structural organization of the secondary xylem in relation to habit.

Anatomy of the Xylem of Pseudolarix

Botanical Gazette, 1934
The anatomical characters reveal that Pseudolarix occupies a relatively high position in the Abietineae. The anatomy, moreover, merges with that of the Taxodineae in a number of features, indicating a general transition in this direction.

The Anatomy and Functioning of the Xylem in Oaks

2017
Because of its economic and ecological importance, the genus Quercus has been relatively intensively studied for its anatomical and hydraulic characteristics, having often been testing ground for development of methods and hypotheses related to tree structure and function.

XYLEM ANATOMY AND HYDRAULIC CONDUCTANCE OF PSILOTUM NUDUM

American Journal of Botany, 1987
Psilotum nudum (L.) Beauv. (Psilotopsida) has a simple, vascularized sporophyte with a dichotomously branching aerial axis. The number and lumen diameters of tracheids in the actinostele decrease in each subsequent branch, leading to an approximate halving of the measured hydraulic conductance (Kh) from segment to segment. To understand how the anatomy

ANATOMY OF THE XYLEM OF SCIADOPITYS

American Journal of Botany, 1935
A review of the literature in a cursory study of the wood structure of Sciadopitys verticillata Sieb. and Zucc. aroused in the writer a desire to investigate thoroughly this phase of the "umbrella pine." This curious monotype is a native of Japan, and, although several general anatomical studies include Sciadopitys, there is no reported investigation ...

Xylem Anatomy of Hibiscus (Malvaceae) in Relation to Habit

Botanical Gazette, 1975
A study of the xylem anatomy of Hibiscus was conducted utilizing 21 species from diverse habit types. Reduction in the amount of secondary xylem that develops, as is generally the case with herbs, has resulted in less axial parenchyma, reduced stratification, decrease of vessel-element length in outer wood, vessel-element length increase in inner wood,

KLEINODENDRON AND XYLEM ANATOMY OF CLUYTIEAE (EUPHORBIACEAE)

American Journal of Botany, 1967
Kleinodendron , a new genus of Euphorbiaceae, was assigned by Smith and Downs to the tribe Cluytieae. A xylem anatomical survey indicates that there are no objections to this placement. Woods of Cluytieae are diverse but may be characterized generally by having pores which average less than 80

Hydraulic Conductance and Xylem Anatomy in Fruit Tree Shoots

Journal of the Japanese Society for Horticultural Science, 2008
Hydraulic conductance is an important index of water flow in plants. We constructed a simple device for measuring the relative hydraulic conductance of fruit tree shoots. The values of vines (kiwifruit and grape) were the highest among 17 species of major temperate fruit trees, followed by deciduous trees (e.g.

THE COMPARATIVE ANATOMY OF THE SECONDARY XYLEM AND THE PHYLOGENY OF THE EUCOMMIACEAE

American Journal of Botany, 1940
IN 1921 Parkin, discussing the systematic position of Eucommia, wrote: "This tree might repay further study from the anatomical side. The wood especially requires minute examination. Facts might possibly be forthcoming which would throw light on its relationship." The present writer (1938) came to the same conclusion in the course of an investigation ...

Variation in xylem anatomy of selected populations of lodgepole pine

Canadian Journal of Forest Research, 2001
Variation in xylem anatomy among selected populations of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) was examined using digital image analysis based on an annual growth ring (age 10) per tree. Four subpopulations were selected using the following criteria for height growth and wood density: (i) fast growth and high density; (
