| We analyzed the mitigating effect of NO3 - and salicylic acid (SA) on the detrimental effects of salt stress by studying the water status of plants of maize grown in Hoagland's medium with NaCl 100 mM as the saline component, to which SA and NO3 - were added in different concentrations as mitigating agents. We evaluated water potential Ψw, osmotic potential Ψs, relative water content (RWC), turgor potential (Ψp ), and the osmotic adjustment (OA) of leaves and roots. SA 0.5 mM mitigated the effects of salinity by increasing the Ψw of the leaf, the Ψsof theroot, the Ψpof the leaf, RWC and OA of the leaf; while NO3 was only effective in combination with SA, mitigating the effects of salinity by increasing... |

| The wine grape (Vitis vinifera) cv. Cabernet Sauvignon has recently been introduced at a 1160 m altitude in the São Joaquim área (Santa Catarina State, Southern Brazil). The aim of this work was to evalúate the maturation of Cabernet Sauvignon grapes subjected to a Y training system or a vertical shoot positioning trellis (VSP). Grapes were sampled at 10-day intervals throughout their maturation during two consecutive vintage years (2004-2005 and 2005-2006). Climate data were assessed. Based on the results obtained in both vintage years at maturity, titratable acidities (TA) ranged from 0.67 to 0.85 g-100 mL-1 of tartaric with the pH fluctuating between 3.49 and 3.77. The maturation Índex (total soluble solids/TA) at maturity ranged from 26 to 35, and was... |
