“…In China, using soil matric potential (SMP) at a depth of 0.2 m measured by tensiometers to control the timing and amount of irrigation during reclamation of salt-affected soils under cropped conditions has been successful carried out under a wide range of conditions. In the Ningxia Plain, China Jiao et al, 2008;Tan and Kang, 2009;Wan et al, 2013), irrigation at a SMP greater than −10 kPa, a highly saline soil (ECe > 20 dS m −1 ) was shifted to a moderately saline soil (7 dS m −1 < ECe < 9 dS m −1 ) in three cropping seasons. In Xinjiang, northwest China, irrigation of cotton at −5 kPa of a saline wasteland for three years resulted in seed-cotton yields reaching 84% of non-saline soil after three years.…”

“…A hortaliça apresenta bons teores de vitaminas A, C e do complexo B para alimentação humana, além dos nutrientes cálcio, ferro, fósforo, magnésio, potássio e sódio (VIDIGAL e PEDROSA, 2007). Entretanto a deficiência hídrica afeta negativamente seu crescimento e rendimento produtivo, apresentando baixa resistência quando submetido a estas condições (WAN et al, 2013).…”

CEP: 39404-547, josianajussara@gmail.com 1 RESUMO Neste ensaio objetivou-se avaliar os efeitos fisiológicos do cultivo de rabanete sob diferentes lâminas de água, simulando a deficiência hídrica (DH). A hipótese central do ensaio seria identificar se a aplicação foliar exógena de ácido ascórbico atenuaria os efeitos fisiológicos dessa deficiência. O delineamento experimental foi em blocos ao acaso em esquema de parcelas subdivididas. Aplicou-se duas tensões de água no solo (10 e 30 kPa) e nas subparcelas, cinco concentrações de ácido ascórbico em solução aquosa (0, 250, 500, 750 e 1000 ppm) com quatro repetições. Verificou-se que a DH alterou os padrões de parâmetros fotossintéticos sendo que, a aplicação foliar de ácido ascórbico promoveu incremento significativo destas variáveis principalmente quando as plantas estavam submetidas ao estresse. Em relação aos tratamentos com a vitamina, maiores valores de taxa fotossintética foram obtidos com a aplicação de 675,8 e 837,3 ppm, nas tensões de 10 e 30 kPa respectivamente aos 30 dias após a emergência (DAE). Com base nos resultados, conclui-se que a aplicação de ácido ascórbico apresenta potencial para atenuar os efeitos da DH em plantas de rabanete.

ASCORBIC ACID, AN ALTERNATIVE TO MINIMIZE THE EFFECTS OF WATER DEFICIENCY IN RADISH 2 ABSTRACT The aim of this study was to evaluate the physiological effects of radish cultivation under different water depths, simulating water deficiency (WD). The central hypothesis of the assay was to assess whether the exogenous foliar application of ascorbic acid could attenuate the physiological effects of this deficiency. The experimental design was a randomized complete block in subdivided plots. Two soil water potentials (10 and 30 kPa) were applied on plots, and the different concentrations of ascorbic acid (0, 250, 500, 750 and 1000 ppm) on the subplots, with four replications. It was verified that WD changes the patterns of photosynthetic parameters, and that the foliar application of ascorbic acid promoted a significant increase of these variables, especially when plants were submitted to stress. With regard to treatments with the vitamin, higher values of photosynthetic rate were obtained with the application of 675.8 and 837.3 ppm, in the tensions of 10 and 30 kPa respectively 30 days after emergency (DAE). Based on the results, it was concluded that the application of ascorbic acid has potential to mitigate the physiological effects of WD on radish plants. Keywords: Raphanus sativus, vitamins, water stress, photosynthesis.

“…A 4-year trial with oil sunflower showed that salt leaching by drip irrigation may change the very strongly salt-affected soil into moderately saline soil . Besides, sunflower was effective in extracting organic chlorine pesticides from the soil (Wan et al, 2013).…”
