| description |
The native and naturalized species of the province of Cordoba, particularly
grasses, have the potential to become elements of low-maintenance garden design.
The aim of this Thesis was to develop the first stage of selection of grasses
with landscape and ornamental characteristics, from native and naturalized
genetic resources. For this purpose, the distribution of the species and the climatic
or edaphic variables that can model their presence were studied. To the
best of our knowledge, the distribution models of many of these species have
been described for the very first time in this work, despite being a tool widely
used in ecological niche studies. Furthermore, the growth habits of the plants
and the color of their leaves and inflorescences throughout the seasons were
characterized. Potential consumer preferences of native plants and reaction to
low-maintenance design proposals were also preliminarily analyzed. Ecological
niche maps of 14 species and the respective results of the Jackknife test were
obtained. The most important climatic and soil variables were observed, and
their response curves were shown. These maps provided essential information
for the combination of native species in gardening projects. The color measurements
and the descriptions of the growth habit showed a great diversity within
the native and naturalized grasses of the province. Species with blooms in different
months were presented. Preliminary results of people’s appreciation of native
materials for gardens were shown, as well as the valuation of gardens made
with native plants. Certain aspects were highly valued by potential consumers
such as average height and the presence of large flowers – native dicotyledonous
plants. In grasses, it was important the average height, its native origin as well
as long flowering periods. The case of Jarava ichu was extensively analyzed, as
it is one of the native grasses with the greatest ornamental potential due to its
extensive area of distribution and good acceptance in gardens in arid regions.
The reproductive method, ploidy and chromosome number were studied setting
the basis for further genetic studies and the development of breeding programs
and germplasm conservation plans. By means of embryological analysis, flow
cytometry and controlled pollination, it was determined that Jarava ichu reproduces
sexually and is preferably allogamous. The results of cytogenetic analysis
suggested that Jarava ichu would be tetraploid (2n=4x=40). These results will
contribute to establishing a group of native and naturalized species of the province
with ornamental potential in future breeding plans and garden designs. |
