| dc.description | Plant genetic resources (PGRs) are the most important elements of
biodiversity behind life systems on this Planediv. Those possessions are
global assets of immeasurable values of present as well as future
generations, sources of improved crop yield and quality, and finally,
represent the very foundation of the humans’ survival (FAO, 1994; ZEF,
1998). Regrettably, many of the vital PGRs are in the greatest threat of
extinction than ever before due to over-exploitations, abolition and
squeezing of their natural habitats. Moreover,the losses of PGRs threaten
agriculture, forestry, medicine, ecology and in the long run the humanity
itself (FAO, 1984). And once a species is extinct, the genes it possessed
are lost forever. | en_US |
| dc.description.abstract | A taxonomic survey work was carried out during March, 2009 to explore the
richness of the plant resources of H.S.T.U. Campus, Dinajpur. The aims of the
survey was to prepare an inventory of those incalculable possessions according
to their 6 main utilities in a users’ friendly data access system, to have tips for
sensible management of those assets and finally, to suggest means for their
further perfection. The appraisal visibly pinpoints that there were in total, 5,134
plant specimens of 382 species, 270 genera and 84 families. The floras had an
assorted assemblage of just 13 gymnosperms but 369 (84 monocots + 285
dicots) angiosperms species. A sum of 285 species of 200 genera from 66
families was dicots but only 84 species, 64 genera and 14 families were
monocots. Again, the campus hosted 215, 76, 32, 31, 18 and 10 species of
ornamental, fruit, timber and forest, plantation, medicinal, and spice species,
respectively. In gymnosperms, thuja had the highest number (314) of plants; in
dicots, mahogany was the dominating species (490) while in monocots, betel
nut (283) was the leading one. In general, the topmost numbers of plants were:
mahogany (490) followed by jackfruit (408), mango (355), thuja (314),
weeping fir (300), betel nut (283), cocoanut (270), neem (251), bead tree (188)
and litchi (167). However, some species were represented by only one sample,
e.g. baobab, allspice, kapok, camphor, agor, taikor, African tulip, ritha etc. The
Premise also accommodated some rare species- agor, allspice, anjan, African
tulip, baobab, brownia, canon ball tree, camphor, kapok, ritha, thaikor, sour sop
etc. Hence, plant luxuries regarding taxonomic aspects were quite amazing.
Yet, anthropogenic plant formations were found as some species, e.g. mango,
jackfruit, mahogany, neem, bead tree etc. were built-in almost each year in the
plantation programs instead of wild as well as other diversified species. So,
proposals were set for plantation programs for preservation of endemic, rare
and threatened plant assets and to defend the genetic multiplicities. | en_US |
