The Seeds of Dicotyledons
The tracheidal tegmen offers a similar problem. Two explanations can be given.
A wholly fibrous tegmen is similar to a wholly fibrous testa, e.g. An- nonaceae. If,
by transference of function, the fibrous character became tegmic and, similarly, ...

Morphogenesis in Plant Tissue Cultures
In Pseudotsuga memiesii shoot cuttings tracheidal nests surrounded by
elongated meristematic cells were formed at the cutting base in peat-perlite (
Mohammed et al., 1989). Actively dividing meristematic cells at the periphery of
the tracheidal ...

Plant Cell and Tissue Culture
Tracheidal Differentiation From Single Cells The techniques of tissue and cell
culture facilitate the study of differentiation of isolated higher plant cells. The
plating technique of Bergmann (1960) served to demonstrate the feasibility of
obtaining ...

Botany For Degree Pteridophyta
Some of these cells develop into tracheidal cells with spiral or annular
thickenings (Fig. 5.11, A). Such cells make their appearance first in the upper free
portion and later in the lower portion. The tracheidal cells of the velum have a
definite ...

Plant Tissue Culture: Theory and Practice
However, tissues derived from the endosperm of euphorbiaceous, loranthaceous
and santalaceous members'readily differentiate tracheidal elements (Johri and
Srivastava, 1973; Johri and Bhojwani, 197 7). The tracheidal elements may ...

Embedded in them are albuminous cells and tracheidal cells. Albuminous cells
are parenchymatous, rich in proteins. They abut on the phloem and they are
involved in the conduction of food material from mesophyll cells to the phloem.

Botany For Degree Gymnosperm (M.E.)
The vascular supply in some ovules consists of a single central strand that enters
the sarcotesta (Fig. 1.21). The main bundle then passes through the sclerotesta
and enters the base of the nucellus where it forms a tracheidal disc from which ...

12.2.2 Evolution of Tracheary Elements in the Higher Plants Extensive
investigations on the comparative morphology of tracheidal elements supported
by the perusal of fossil history have made it possible to trace accurately the
evolution of ...

The midrib ends into a columnar tracheidal net, 17. 13 p long and 5.35 p wide.
Polygons are 22.47 p long and 16.06 p wide with a solitary single or once
branched free included veinlet. The marginal vein is 3.21 p away from the leaf
margin ...
