The main objective of this study is to examine whether
exogenously applied Ascorbic acid (AsA) may enhance the salt tolerance
in durum wheat (Triticum durum
Desf. var. Waha). Two weeks old seedling, grown in plastic pots of 1kg,
were subjected to salt stress by adding 25ml of NaCl (150mm), and
treated or not with the addition of ascorbic acid (0.7 mM). Two weeks
after salt stress, plants were harvested and the various measures were
recorded.
The effects of salt stress, in the presence and absence of vitamin C,
on the leaf growth, leaf area (LA) and some physiological and
biochemical changes were investigated. It was established that the
application of vitamin C mitigate to variable extent the adverse effect
of salt stress on plant growth, may be due, in part, to increased leaf
area, improved chlorophyll and carotenoid contents, enhanced proline
accumulation and decreased H2O2 content.
In conclusion, we can say that treatment with ascorbic acid improve
salt tolerance in durum wheat through the enhancement of multiple
processes.
