“…However, in the present study, most of the varieties showed higher levels of proline and lower level of dry and fresh biomass under salt stress condition (200 mM and 300 mM). These findings are consistent with Kanawapee et al (2013) who reported that under salt stress condition the highly susceptible cultivars accumulated the highest level of proline than the tolerant cultivars. This might indicate that over accumulation of proline was related to a symptom of salt injury rather than an indicator of salt resistance (Lutts et al 1999).…”

Intervarietal variation in salt tolerance of lentil (Lens culinaris Medik.) in pot experiments

Seven lentil (Lens culinaris Medik.) varieties were grown in pots irrigated with NaCl solution of different concentrations (0, 100, 200 and 300 mM) to assess their salinity tolerance potentials. Data revealed that the highest and the lowest salt tolerance were shown by BARI masur-5 (168.50%) and BARI masur-2 (56.32%), respectively. Cluster analysis based on the salt tolerance indices also showed grouping of the varieties into 4 clusters where BARI masur-5 was found highly salt tolerant, BARI masur-6 was moderately salt tolerant and BARI masur-1 and BARI masur-2 were least tolerant. Although shoot height, fresh weight and water content decreased, root length and root to shoot ratio increased significantly with the increase of salt concentrations in the varieties tested.

“…In a similar way, Kong-ngern et al (2012) observed that the salt-sensitive KDML 105 accumulated the highest amount of root proline 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) supported that under salt stress the highly susceptible cultivars accumulated the highest level of proline than the tolerant cultivars. However, Igarashi et al (1997) suggested that proline accumulation was related to the degree of salt tolerance and rice plants accumulating high level of proline under salt stress were able to maintain higher green leaf area (Pongprayoon et al, 2008).…”

Salinity tolerance levels and physiological changes were evaluated for twelve rice cultivars, including four white rice and eight black glutinous rice cultivars, during their seedling stage in response to salinity stress at 100 mM NaCl. All the rice cultivars evaluated showed an apparent decrease in growth characteristics and chlorophyll accumulation under salinity stress. By contrast an increase in proline, hydrogen peroxide, peroxidase (POX) activity and anthocyanins were observed for all cultivars. The K(+)/Na(+) ratios evaluated for all rice cultivars were noted to be highly correlated with the salinity scores thus indicating that the K(+)/Na(+) ratio serves as a reliable indicator of salt stress tolerance in rice. Principal component analysis (PCA) based on physiological salt tolerance indexes could clearly distinguish rice cultivars into 4 salt tolerance clusters. Noteworthy, in comparison to the salt-sensitive ones, rice cultivars that possessed higher degrees of salt tolerance displayed more enhanced activity of catalase (CAT), a smaller increase in anthocyanin, hydrogen peroxide and proline content but a smaller drop in the K(+)/Na(+) ratio and chlorophyll accumulation.

“…sativa L.cv. RD6., a moderately salt tolerance variety (Kanawapee et al 2013), was used in these experiments. Rice seeds were surface disinfected by immersion in 70% (v/v) ethanol plus 0.3% (v/v) tween 80 for 5 min and 3% (w/v) sodium hypochlorite containing 0.3% (v/v) Tween 80 for 15 min.…”

“…In addition, saline soil was descriptive of a soil having an electrical conductivity (EC e ) > 4dS/m, approximately 0.2% (w/v) of NaCl or more (Richard 1954). A list of rice cultivated in saline paddy fields, in northeast Thailand, showed various salt-tolerant groups of sensitive (0-2 dS/m), moderately sensitive (2-4 dS/m), moderately tolerant (4-8 dS/m), and tolerant (8-16 dS/ m) (Kanawapee et al 2013). Therefore, the effects of salinity conditions of 0-16 dS/m was studied on the growth and IAA production of Pseudomonas sp.…”

“…The total area salinity amounts to 28.5 thousand square kilometers of the northeastern land area (Land Development Department 1991). The effect of saline on rice depends on several factors: (1) the intensity of the stress, (2) the climatic conditions, and (3) the resistance level of the genotype (Asch & Wopereis 2001;Kanawapee et al 2013). An average seasonal salinity of field water in excess of 1.9 dS/m can also reduce grain yields, and salinity affects rice yield at or above 3.0 dS/m (Grattan et al 2002).…”

The bacteria of PDMCd0501, PDMCd2007, and PDMZnCd2003 were isolated from a Zn/Cd contaminated soil. They were classified as salt-tolerant bacteria in this experiment. The bacteria had indole-3-acetic acids (IAA) production, nitrogen fixation, and phosphate solubilization, under 8% (w/v) NaCl condition. Biochemical test (API 20E) and 16S rDNA sequencing identified PDMCd2007 and PDMCd0501 as Serratia sp. and PDMZnCd2003 was Pseudomonas sp. The effect of Pseudomonas sp. PDMZnCd2003 on the germination and seedlings of Oryza sativa L.cv. RD6 was determined under a salinity of 0-16 dS/m. The salinity levels of 4-16 dS/m affected to decrease germination and seedlings of rice. Comparison between uninoculated and inoculated system, however, Pseudomonas sp. PDMZnCd2003 had a negative impact on the rice growth. This unexpected effect was a case that should be concerned and studied further before application as a plant growth-promoting bacteria (PGPB).
