Zusammenfassung: | One of the favorite issues for the ecologists and physiologists is searching the effects of the environmental factors (i.e. salinity, temperature, drought, rainfall, etc.) in the plants. In the present paper, the response of the enzymatic and non-enzymatic antioxidants in different populations of
Pistacia atlantica
and
Pistacia khinjuk
were investigated under different climatic conditions. Ten trees of any population of
P. atlantica
and
P. khinjuk
were garnered from diverse locations of Iran in September, 2017. The leaf samples were transferred to the laboratory using liquid nitrogen and were frozen for analysis of enzymatic and non-enzymatic antioxidants in different populations. According to the soil and climatic analyses, Jebalbarez, Sangan and Anjirk are more stressful compared to other regions. Generally, our results unveiled that the contents of protein, proline and total soluble sugar like compatible osmolytes in some populations of
P. atlantica
are higher than those of
P. khinjuk
. The antioxidant enzyme activities including superoxide dismutase, peroxidase and polyphenol oxidase were more in
P. khinjuk.
The activity of key enzymes in the biosynthesis pathway of the phenolic compounds in
P. khinjuk
was more than that of
P. atlantica
. Furthermore, the content of non-enzymatic antioxidants such as phenol, flavonoids and tocopherols in
P. atlantica
was higher than that of
P. khinjuk
. The respiratory enzymes (e.g. aconitase, fumarase and succinate dehydrogenase) had high activity in
P. khinjuk
.
P. atlantica
used more non-enzymatic systems; however,
P. khinjuk
applied the enzymatic system in response to different climatic conditions. In conclusion, the present study revealed that
P. atlantica
used more of the osmoregulation and non-enzymatic system; however,
P. khinjuk
utilized the enzymatic antioxidant system and the respiratory enzymes in response to the ecophysiological conditions. |
