Abstract:
The climatic changes and the rise in temperature by effect of the green house. The
aalysis of the thermal variation of the area of El Kala are located in the forks 35 – 45°C with
variable duration and frequencies, but much more it concentrated in the range 36 – 40°C,
fu
rthermore, it hasn’t any effect on the biology core in wich the temperament is thermophyl.
The results obtained on the biochimical level show that the sowings are adopted very well
with these high temperatures.except some sowings with growth beig faded.
The varions studied organs show that the “ proline” and the soluble sugars
concentrated preferentially on the level of leaves, root and stems.
This work is of a partical interest for the forestier in order to evaluate the risk in a
medium-term of heat bodies on the afforestration of the Cork Oak .
