Cite as: Gomes, M.A.C. et al. Salinity effects on photosynthetic pigments, proline, biomass and nitric oxide in Salvinia auriculata Aubl. Acta Limnologica Brasiliensia, 2017, vol. 29, e9. Abstract: Aims: Effects of salt stress on the physiology of Salvinia auriculata were investigated. Method: Plants were supplemented with 0, 50, 100 and 150 mmol L -1 NaCl and incubated for 5 days. NO content was evaluated after 2 hours and 5 days. Photosynthetic pigments, proline and nutrients were analyzed after 5 days. Major Results: Higher chlorophyll a content was observed in plants treated with 50 mmol L -1 , decreasing in higher NaCl concentrations, while chorophyll b content decreased with increasing NaCl concentrations. Exposure to 50 mmol L -1 NaCl increased biomass, while higher concentrations caused loss of biomass. Ca, K and Mg decreased with increasing NaCl concentrations, and the Na/K ratio was significantly increased at 150 mmol L -1 NaCl. Proline increased significantly at 150 mmol L -1 . Extracellular NO content increased after 2 hours, with significantly higher NO concentrations in roots observed at 50 mmol L -1 . Decreases in NO content were observed after 5 days. Conclusions: The results indicate that moderate salinity induces NO production earlier during incubation, probably associated to signaling for the production of compounds that assist in stress tolerance. At higher concentrations, this tolerance is reduced. This allows for further understanding of the physiological and biochemical mechanisms associated with the adaptation of this macrophyte to saline conditions, which, in turn, affect this species ecology and distribution in coastal areas.Keywords: Salvinia auriculata; salinity stress; nitric oxide; clorophyll; NaCl; macrophyte.Resumo: Objetivos: Efeitos do estresse salino sobre a fisiologia de Salvinia auriculata foram investigados.

“…Application of NaCl at concentrations on 50 at 150mM with inoculated by B.cinerea enhanced the plant height, fresh weight and dry weight compared to the plants inoculated and irrigated by distilled water, which may be increase tolerance or plant response to salt. Other results that support what has been shown here, are those by Amira and Abdul Qados (2011) with his study on Vicia faba; Hamada (1995) on maize Zea mays L; Memon et al (2010) in their study on Brassica campestris L; and ûnally by Misra et al (1997) with their study on rice seedlings Oryza sativa L. vr. Damodar, where they showed that the use of low levels of salt stress led to increases in plants lengths.…”

A greenhouse experiment was conducted to investigate the effect of different levels of NaCl salt on tomato upon B. cinerea infection the causal agent of gray mold disease. The disease assessment was recorded after inoculation by using the scale based on percentage leaf area affected, and the growth of the plants was recorded for each treatment. Three weeks after inoculation by conidial suspension, the estimated disease severity on plants of tomato was 35.18% compared to the control. The highest incidence disease increase of gray mold (39.21%) was obtained with using 300 mM of NaCl after inoculation with B. cinerea compared with the other concentrations and as well as distilled water. Under severe salt stress (150 and 300mM) increased susceptibility of gray mold disease severity were observed in plants inoculated with B. cinerea, while under mild salt stress (50mM of NaCl) this effect was reversed. The treatment of plant by B.cinerea has reduced the growth of the aerial part of tomato plants (39.06%) after three weeks inoculation compared to the control. Three levels of NaCl (50, 100 and 150mM) increased respectively the plant height from 12.73 to 29.84%, 0.28 to 27.16% for the fresh eight and 5.75 to 33.35% for dry weight compared to the plants inoculated and irrigated by distilled water. NaCl addition at 300mM on plants inoculated with B. cinerea decreased the height, fresh weight and dry weight at 0.99, 4.45 and 11.01% respectively.

“…Increasing levels of salinity result in a decline in chlorophyll content (Sharma et al 2013). The decrease in chlorophyll content under stress conditions can be attributed to the increased activity of the chlorophylldegrading enzyme chlorophyllaze (Misra et al 1997;Ali et al 2008), while exogenous applications of BRs have an ameliorating role in chlorophyll content under various stresses. Brassinoids enhance chlorophyll content under salinity stress (Mahajan et al 2005;Karlidag et al 2011;Ahmad et al 2013;Alyemeni et al 2013).…”

Regulation of Growth and Physiological traits of Cucumber (Cucumis sativus L.) through various levels of 28-Homobrassinolide under salt stress conditions

Brassinoids are plant steroidal hormones that are ubiquitous in the plant kingdom and regulate a wide range of physiological and stress responses. In a plastic tunnel pot bioassay experiment, three levels of 28-homobrassinolide (HBL) at 1, 3, and 5 μmol L −1 were tested for growth and physiological attributes of cucumber cultivars 'Jinyou 1' (salt-sensitive) and 'Changchun Mici' (salt-tolerant), grown at various salt stress conditions (60 and 120 mmol L −1). Cucumber plants of both cultivars subjected to salt stress exhibited reduced growth attributes and altered antioxidant enzymes at 60 and 120 mmol L −1. However, the deleterious effects of salt stress were partially improved by HBL. The foliar application of HBL enhanced shoot and root fresh and dry weight and chlorophyll content at 60 and 120 mmol L −1 NaCl stress in 'Jinyou 1' and 'Changchun Mici', respectively. Homobrassinolide application also altered the antioxidant enzyme levels by increasing super oxide dismutase and peroxidase levels and decreased malondialdehyde content under 60 and 120 mmol L −1 stress in both plant cultivars. Overall results showed that HBL could enhance growth attributes, chlorophyll content, and antioxidant enzymes for both of the cultivars under mild and high NaCl stress.
