| Résumé : |
Biological invasions are a concern of current as well as climate change. Indeed, they can be regarded as an experimental manipulation of biodiversity on a large scale and used to test fundamental hypotheses in ecology. In particular, they allow exploration of impaired functioning of ecosystems by altering species assemblage. This work is to determine the adaptability of the ailanthus dwarf capacity in the region of Constantine, thermal variability for using biochemical markers (chlorophyll, sugars and proline) and the assessment of its ecological character physico-chemical characterization of the soil.
The seedlings under semi controlled under stress of short duration (03 hours) at a temperature ranging from 30°C to 50°C and in which the biochemical parameters are quantized (chlorophyll, sugars and proline). The results show that the seed of Ailanthus are capable to accumulate different osmolytes like proline and sugars in the various organs in response to thermal stress and the highest levels are stored in the roots for the proline and in leaves for sugars reflecting the resistance of this species to the stress. The physicochemical characterization of the environment reveals a high C/N ratio reflecting very favorable conditions for the decomposition of the carbonaceous material and very low levels of trace metals that reflect the geochemical background elements. thus, the species studied showed a good ability to grow in the study site. |
