BiologieTags : Biologie Végétale:Ecophysiologie et biotechnologie végétale Chèorophylle Proline Sucres solubles Stress thermique Cedrus atlantica Protéines solubles heat stress soluble sugars chlorophyll soluble proteins Index. décimale : 570 Sciences de la vie. Biologie Résumé : Natural disturbances and human but also the changes expected for the next century are likely to substantially and permanently alter ecosystems and their diversity. Future climate changes are likely having an irreversible impact. The adaptation of tree species composing these ecosystems may be difficult because the speed of climate change may not allow them to gradually migrate to more favorable areas. In this context, our work focuses on the aspect of adaptive capacity and tolerance of seedlings of cedar Atlas under conditions of heat stress in the region of Batna and semi-controlled conditions where the plants suffer a thermal shock a period of three hours at temperatures between -10 ° C and 44 ° C. Batna region enjoys a Mediterranean semi-arid climate with a cold Q2 = 32, m =- 0.43 ° C and M = 36.22 ° C. The study area was treated on the thermal and revealed a multitude of stress winter, spring and summer. The accumulation of various osmolytes (soluble sugars, proline, and protein) shows predominance in the new shoots, old shoots, stems and roots. Chlorophyll undergoes a total decline of 50% mainly in the new shoots. Stomatal regulation is
manifested by a closure 12h at temperature close to 34 ° C.
The applied stress naturally or experimentally induced structural changes affecting the variations in accumulation of various osmolytes and chlorophyll thus demonstrating the ability to adapt to heat stress. The temperature range -6 ° C, -10 ° C and 44 ° C is characterized by the most important concentration of osmolytes in the organs of seedlingsNote de contenu : Annexes.

الحلبي الإجهاد الحراري التحمل البرولین السكریات القابلة للتحلل الكلوروفیل البروتینات المقاومة الثغریةIndex. décimale : 570 Sciences de la vie. Biologie Résumé : In Algeria, the pine forests are concentrated mainly in arid and semi arid regions where the climatic conditions limit the production potential seriously. Due to the unpredictable nature of thermal stress, tolerance is the most effective strategy in situations of severe and prolonged stress. At the time of this tolerance one attends modifications of structures or functions which increase the probability of being useful and production plants in these conditions.
In this study, seedlings of Aleppo pine are conducted according to two tests, first under semicontrolled conditions and under natural conditions. We fixed as objective to evaluate the effect of thermal stress from the biochemical markers such as the synthesis of proline, sugars, chlorophyll, proteins and to examine differences in these parameters between the organ (old needles and young shoots, stems and roots). The accumulation of various osmolytes under natural conditions showed that the sugars and proline, are much more concentrated in shoots (needles), stems and roots, but the winter period (hardness)and spring (active growth period) that give the greatest rate, the values of chlorophyll observed significant falls. The intensity of stress is positively correlated with proline, soluble sugars, and negatively with chlorophylls in winter and summer. At leaf level, high temperatures are manifested by a change in gas exchange following the closure of stomatal bands which may reflect an adaptation of the needles of Aleppo pine to heat stress. Thus, the biochemical parameters measured after the application of heat treatments also reflect a tolerance to low and high temperatures. These conditions have resulted in seedlings of Aleppo pine a reduction of chlorophyll content, an accumulation of osmoticums including proline and sugars as well as an increase in protein synthesis. Chlorophyll is negatively correlated with the other metabolites, which are correlated with each other. The results show that the concentrations of these compounds vary depending on the seedling organ and the severity of stress with thermal limits between -10 °C and 42 °C. On the morphological plan, growth of seedlings of Aleppo pine is greatly weakened by the winter conditions. However, the rate of recovery is improved during the spring season and reaches a maximum value during the summer season.
In conclusion, the study revealed the thermophilous character of seedlings of Aleppo pine and shows that these last used the same strategies of tolerance opposite to the thermal stress but the only difference is in the synthesis rates of the studied markers.Note de contenu : Annexes.
