“…The increase in hydrogen peroxide concentration in response to salt stress was observed with other plant species, e.g., mung bean (Vigna radiata), rice (Oryza sativa), and mulberry (Morus sp.) [54,60,61]. The results of our study indicated a positive correlation between the level of hydrogen peroxide in roots, stems and leaves of B. vulgaris and NaCl concentration.…”

Increasing land salinization in recent decades has led to a decrease in crop productivity worldwide. We hypothesized that bioaugmentation of beetroot (Beta vulgaris) with halotolerant endophytic bacterial strains isolated from the obligatory halophytic plant Salicornia europaea L. may mitigate salt stress in new host plants. Therefore, we investigated the effects of inoculation with Pseudomonas stutzeri ISE12 or Kushneria marisflavi CSE9 on B. vulgaris growth in substrates enriched with various NaCl concentrations (0, 50, 150, 300 mM). The results of this study indicated that bioaugmentation with either bacteria resulted in improved growth parameters and increased chlorophyll content, as well as decreased proline and hydrogen peroxide concentrations, in B. vulgaris organs. However, K. marisflavi CSE9 was more efficient in achieving salt stress mitigation than P. stutzeri ISE12. In conclusion, the range of salinity tolerance seems to be a key parameter in the selection of strains for beet inoculation. The selected halotolerant endophytes (P. stutzeri ISE12 and K. marisflavi CSE9) isolated from the roots of obligatory halophytic S. europaea may be employed for plant growth promotion, especially in saline areas, and have potential applications in sustainable agriculture.

“…The correlation table showed that MDA and proline had a significant positive correlation (r 2 = 0.82; p ≤ 0.05), and this suggests that the proline and lipid peroxidation mechanism might be related to the water stress defense mechanism in rice [60,61]. The increase in proline and MDA content under abiotic stress was also observed by Wandkhade and Sans [62] and Kong et al [63] in rice exposed to salinity stress. The current results showed that application of potassium during drought or cyclic water availability can mitigate the effects by an increase in the production of proline and MDA in the rice seedlings.…”

Abstract:The use of periodical water stress and potassium fertilization may enhance rice tolerance to drought stress and improve the crop's instantaneous water use efficiency without much yield reduction. This study was conducted to assess the effects of different periodical water stress combined with potassium fertilization regimes on growth, yield, leaf gas exchanges and biochemical changes in rice grown in pots and compare them with standard local rice grower practices. Five treatments including (1) standard local grower's practice (control, 80CF = 80 kg K 2 O/ha + control flooding); (2) 120PW15 = 120 kg K 2 O/ha + periodical water stress for 15 days; (3) 120DS15V = 120 kg K 2 O/ha + drought stress for 15 days during the vegetative stage; (4) 120DS25V = 120 kg K 2 O/ha + drought stress for 25 days and (5) 120DS15R = 120 kg K 2 O/ha + drought stress for 15 days during the reproductive stage, were evaluated in this experiment. Control and 120PW15 treatments were stopped at 100 DAS, and continuously saturated conditions were applied OPEN ACCESSMolecules 2014, 19 1796 until harvest. It was found that rice under 120PW15 treatment showed tolerance to drought stress evidenced by increased water use efficiency, peroxidase (POX), catalase (CAT) and proline levels, maximum efficiency of photosystem II (f v /f m ) and lower minimal fluorescence (f o ), compared to other treatments. Path coefficient analysis revealed that most of parameters contribute directly rather than indirectly to rice yield. In this experiment, there were four factors that are directly involved with rice yield: grain soluble sugar, photosynthesis, water use efficiency and total chlorophyll content. The residual factors affecting rice yield are observed to be quite low in the experiment (0.350), confirming that rice yield was mostly influenced by the parameters measured during the study.

“…Our findings were consistent with Ghosh et al (2011) who reported that the salt-tolerant Pokkali and Nonabokra exhibited the increase in proline in the rice seedlings under salt stress conditions. In a similar way, Kong-ngern et al (2012) showed that the proline was so high in the roots of the salt-sensitive KDML 105 followed by the salt-sensitive Pathumthani 60 and the moderately tolerant Luang Anan and the tolerant Pokkali under salinity stress. In addition, Kanawapee et al (2013) also showed that under salt stress treatment, the highly susceptible cultivars had the higher levels of proline than the tolerant ones.…”

Changes in the antioxidant enzymes, lipid peroxidation, sodium and potassium, chlorophyll, HO and proline content were monitored in the leaves of 42 rice varieties which were not yet well-documented for the salinity tolerance under different salinity levels. The tolerant varieties (FL478, Hassani, Shahpasand, Gharib and Nemat) showed signs of tolerance (lower Na/K ratio, high proline accumulation, less membrane damage, lower HO production, and higher superoxide dismutase and catalase activity) very well. The positive relationship between the level of salt tolerance and the amount of proline accumulation in the rice varieties support the important role of proline under the salt stress. The varieties were genotyped for 12 microsatellite markers that were closely linked to QTL. The results of association analysis indicated that RM1287, RM8094, RM3412 and AP3206 markers had the high value of R for the regression models of the studied traits. It shows the important role of in controlling physio-biochemical traits. The results can be used in the future marker assisted selection (MAS) directly, if the results are confirmed.
