“…From the other hand, the enhanced ROS scavenging capacity could be the response to higher ROS production of sensitive genotypes compared to tolerant once as showed in winter wheat (Simova-Stoilova et al, 2009). Other studies on jute, alfalfa, tomato and wheat have reported declining or unchanged levels of antioxidative enzymes under drought (Irigoyen et al, 1992;Őnyayar et al, 2005;Nikolaeva et al, 2010), and in drought tolerant transgenic groundnut, ROS scavenging enzymes activities were not linked to tolerance-related traits (Bhatnagar-Mathur et al, 2009). In pearl millet Patil et al, (2005) found that all these enzymes increased under drought in field conditions, although SOD increased only in later drought phases, whereas APX and CAT activity rose soon after stress imposition.…”

“…In pearl millet Patil et al, (2005) found that all these enzymes increased under drought in field conditions, although SOD increased only in later drought phases, whereas APX and CAT activity rose soon after stress imposition. So, the relationship between the plant's capacity to tolerate stress and the activity of ROS scavenging mechanisms is still not clear and seems to be highly variable depending on species, developmental and metabolic state of plant, and the duration of stress (Razmjoo et al, 2008, Nikolaeva et al, 2010.…”

The recovery ability of barley plants from salt stress conditions was assessed using foliar application of salicylic acid (SA) in a study conducted under controlled conditions. The barley plants (Hordeum vulgare L. 'Reyhan') were subjected to saline water with varying salinity levels (tap water 0.67 dS m -1 as control, 3, 6, 9, and 12 dS m -1 ) from 14 to 42 days after sowing (DAS). Then the plants were subjected to recovery treatments for 4 weeks, from 42 to 70 DAS. The recovery treatments included: non-recovery (R 0 ), irrigation with tap water (R 1 ), and irrigation with tap water + 2 foliar applications of SA with a 1-week interval (R 2 ). The results showed that salt stress decreased shoot and root dry weight, leaf K + concentration, and photosynthesis rate, while it increased leaf Na + concentration and free proline, soluble protein, and chlorophyll contents. These reductions were related directly to stress intensity. Both recovery treatments increased shoot dry weight, Na + concentration, free proline, chlorophyll content, and photosynthetic rate. Compensation of root dry weight losses due to salt stress was observed only in R 1 . However, for other measured traits recovery ability with R 2 was greater than with R 1 . Overall, it appeared that although recovery treatments could not fully eliminate salt-induced damages, the recovery treatment with SA proved to be very effective in alleviating the adverse effects of salt stress on barley plants.

“…Lipid peroxidation level that changes by time can be explained as low antioxidative defense system performance [19]. [20] reported that proline (an antioxidant) content increase according to drought at the study of developing drought tolerance bread wheat cultivars. At the same study it was also told that increased lipid peroxidation level effect antioxidative defense system negatively.…”
