Anatomy of Grass Culms

Klappentext

The atlas presents the first time an overview of anatomical structures
of Poaceae (Gramineae) culms. Integrated are cross-sections
of 80 genera with 300 species of the European alpine region from
sea level to the alpine zone. All sections are double stained with
safranin and astrablue and documented by high quality microphotographs
with magnifications of 100 and 400 times. Anatomical descriptions
highlight the most characteristic features. The herbarium
voucher, their labels and the position of section are documented on
http://www. herbarien. uzh. ch/en/datenbanken/belegsuche. html.
The microstructure of Poaceae culms is relatively homogeneous, however some features can be related
to plant size, vegetation zones and humidity conditions. Culm size is the main driver for anatomical adaptions.
Important culm characteristics are the form of the unlignified assimilating parts (chlorenchyma),
width, form and density of the lignified culm-walls and the distribution of the vascular bundles. The study
is based exclusively on material from the United Herbaria Z+ZT of the University and ETH Zürich and
contains specimens from Austria, Germany, France and Switzerland.
