“…Paclobutrazol treatment to the drought stressed plants decreased glycine betaine content but it was higher than that of control. Similar results were observed in Arachis hypogaea (Girija et al, 2002). The accumulation of glycine betaine might serve as an intercellular osmoticum and it can be closely correlated with the elevation of osmotic pressure (Kavikishore et al, 1995).…”

A pot-culture experiment was conducted to estimate the ameliorating effect of triazole compounds Hexaconazole, Tebuconazole and Propiconazole on drought stress in sunflower (Helianthus annuus L.). The plants were subjected to drought (DID) stress after four days of interval from the 30th day of sowing (DAS). One-day-interval irrigation was kept as control. The plant samples were collected and separated into root, stem and leaf for estimating the amino acid (AA), proline (PRO) and glycine betaine (GB) contents and the activities of antioxidant enzymes. Drought stress and triazole treatments increased AA, PRO and GB contents, superoxide dismutase (SOD), ascorbate peroxidase (APX) and catalase (CAT) activities when compared to control. From the results of this investigation, it can be concluded that the application of triazole compounds caused a partial amelioration of the adverse effects of drought stress by its influence on antioxidant potentials in H. annuus.

“…Ghazvini and Badami-ezarand. It was suggested that the addition of Ca to the root environment of NaCl-stressed plants would help organic solute accumulation in the roots, which could contribute to root osmotic adjustment, in turn favouring the maintenance of plant-water balance and growth [32].…”

--Introduction. Saline soils may exert a different effect on seed germination and seedling growth. Materials and methods. The seeds of two rootstocks of pistachio (Pistacia vera), Ghazvini and Badami-e-zarand, were incubated at 20°C in the dark in a 150 mM NaCl solution or in 150 mM NaCl solutions amended with (50, 100 and 150) mM CaSO 4 . Seeds were planted in pots containing a mixture of garden soil, sand and compost (1/3 v/v) to investigate the effect of calcium sulphate on plants grown under salt stress. Irrigation water treatments were control (deionised water alone); salinity stress (150 mM NaCl); salinity with 50 mM CaSO 4 ; salinity with 100 mM CaSO 4 ; and salinity with 150 mM CaSO 4 . Results and discussion. In all treatments, both the final germination percentage and the final percentage of seeds with emerging seedlings longer than 20 mm were higher in the Ghazvini rootstock than in the Badami-e-zarand rootstock. Both the final germination percentage and the final percentage of seeds with emerging seedlings were significantly increased with increasing CaSO 4 concentration, except at the highest CaSO 4 concentration. The plants grown under 150 mM NaCl produced less dry matter and had lower chlorophyll content than those grown without NaCl. Supplementary CaSO 4 only at (50 and 100) mM concentrations ameliorated the negative effects of salinity on plant dry matter and chlorophyll content. Sodium (Na) concentration in plant tissues increased in both leaves and roots of plants under the NaCl treatment alone. The Ghazvini rootstock had much lower Na. Additions of CaSO 4 significantly lowered the concentration of Na in both leaves and roots. The Ghazvini rootstock was more tolerant to salinity than the Badami-e-zarand rootstock. The accumulation of Na in leaves and roots indicates a possible mechanism whereby cv. Ghazvini copes with salinity in the rooting medium, and/or may indicate the existence of an inhibition mechanism of Na transport to leaves. Concentrations of Ca and K were lower in the plants grown at high NaCl concentration than in those under the control treatment, and, for the cv. Ghazvini, these two element's concentrations were increased in both leaves and roots for the plants with calcium sulphate treatment; for the cv. Badamie-zarand, these concentrations were increased in only the roots.Iran Islamic Republic / Pistacia vera / germination / growth / osmotic stress / saline water / calcium sulphate / salt tolerance Le calcium induit une tolérance au sel dans les porte-greffes de pistachiers.Résumé --Introduction.

“…Este íon, além de reduzir a absorção de íons potencialmente tóxicos, como o Na + , favorece a absorção de íons essenciais, como o K + (Colmer et al, 1996) e o próprio Ca 2+ (Maas & Grieve, 1987). Recentemente admitiu-se que o Ca 2+ também promove o acúmulo de solutos orgânicos, como a prolina (Läuchli et al, 1994;Colmer et al, 1996) e a glicinabetaina (Girija et al, 2002), os quais possibilitariam o estabelecimento de um equilíbrio osmótico no citoplasma mais compatível com o metabolismo celular, favorecendo o crescimento das plântulas sob condições de estresse salino.…”
