“…Lower values of SP were observed for DI plants and higher concentrations of TBARS in R plants were detected in 2013 (Table III). Interestingly, TBARS concentration could be considered as a biochemical marker for reactive oxygen species mediated injury, hence in 2013 the higher concentration of TBARS in R plants confirmed a greater oxidative damage of cell membranes by lipid peroxidation (Beis and Patakas, 2012).…”

SUMMARYIrrigation has been considered a controversial practice in European traditional viticulture due to potential alterations in the balance between vegetative growth and yield. In this regard, the influence of surface (DI) and subsurface (SDI) drip irrigation on physiological performance of the 'Godello' grapevine (Vitis vinifera L.) cultivar was compared with a non-irrigated control (R) over three consecutive growing seasons (2012)(2013)(2014) in NW Spain. Irrigation improved vine water status; R plants reached a minimum of midday leaf water potential of -1.5 MPa, whereas DI and SDI plants reached -1.3 MPa. Stomatal conductance was unaffected by irrigation as well as chlorophyll a fluorescence. However, photosynthetic pigments were present at higher concentrations in leaves from irrigated plants than in those from R plants in 2013. In addition, R plants showed higher values for the indicators of oxidative damage. No significant yield improvements were observed for irrigated plants, although the trend was to obtain slightly higher yields under irrigation in years with low rainfall amounts. This may not encourage growers to establish irrigation systems on their vineyards. However, these results may be important with the objectives of stabilizing yield from year to year. RESUMOA rega tem sido considerada uma prática controversa na viticultura tradicional Europeia devido a potenciais alterações no equilíbrio entre crescimento vegetativo e rendimento. A este respeito, a influência da irrigação por gotejamento superficial (DI) e subsuperficial (SDI) sobre o desempenho fisiológico da variedade 'Godello' (Vitis vinifera L.) foi comparada com uma testemunha em condições de sequeiro (R) ao longo de três anos consecutivos (2012-2014) no noroeste de Espanha. A rega melhorou o estado hídrico da videira; as plantas do tratamento R atingiram potenciais hídricos foliares ao meio-dia de -1.5 MPa, comparativamente a um valor de -1.3 MPa para as plantas dos tratamentos DI e SDI. A conductância estomática e a fluorescência da clorofila a não foram afectadas pela rega. No entanto, os pigmentos fotossintéticos apresentaram maiores concentrações em folhas de plantas regadas quando se comparam com as plantas do tratamento R em 2013. Além disso, as plantas do tratamento R apresentaram valores superiores para os indicadores de danos oxidativos. Não foi detectado nenhum incremento do rendimento nas plantas regadas, embora se tenha observado uma tendência para obtenção de rendimentos ligeiramente mais elevados sob rega em anos com baixa pluviosidade. Tal poderá não encorajar aos viticultores a implementar sistemas de rega nas suas vinhas. No entanto, estes resultados podem ser importantes para a estabilização do rendimento de ano para ano.

“…One of the possible sources of H 2 O 2 production in plants is the high P r which usually occurs in the peroxisomes. In V. vinifera several studies have ascertained that the rate of P r is cultivar-dependent (Düring, 1988;Beis and Patakas, 2012;Hochberg et al, 2013). Indeed, contrary to cv.…”

“…Recently, it has emerged that the mechanisms that allow the various varieties to adapt to summer stresses are mediated by stomatal sensitivity and are genetically controlled (Medrano et al, 2003;Beis and Patakas, 2012;Hochberg et al, 2013;Palliotti et al, 2014). According to stomata kinetics under drought, V. vinifera embraces varieties classified as isohydric, which are capable of maintaining a fairly constant midday leaf water potential regardless of soil water availability by means of early stomatal closure, and anisohydric, which maximize photosynthetic gain by maintaining stomata open despite a large leaf water potential drop (Tardieu and Simmoneau, 1998).…”

“…Superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) are major components of the enzymatic defence antioxidant system.

Growth, photosynthetic characteristics, chlorophyll (Chl) fluorescence parameters, and peroxidation of membrane lipid of Cryptotaenia japonica were studied under differing irradiances (15, 35, 60, and 100 % of full irradiance). At full irradiance, C. japonica exhibited a typical decline in net photosynthetic rate (P N ) at midday, which was not observed in the other irradiance treatments. This indicates a possible photoinhibition for C. japonica at the high irradiance. Diurnal patterns of stomatal conductance (g s ) were remarkably similar to those of P N in each irradiance treatment, and the intercellular CO 2 concentration (c i ) had the opposite trend. C. japonica growing under 60 % of the full irradiance exhibited the highest plant height, stem diameter, leaf area, and biomass. The initial fluorescence (F 0 ) value was lowest at 60 % of the full irradiance. Maximal fluorescence (F m ), potential activity of photosystem II (PS II) (F v /F 0 ), and maximal photochemical efficiency of PS II (F v /F m ) values were highest at 60 % of full irradiance and lowest at 15 % of the full irradiance. The malondialdehyde (MDA) content in 15 % and 100 % of the full irradiance were higher than under the other irradiances. During the treatment, catalase, peroxidase, and superoxide dismutase activities firstly increased and then declined under 15 % and 100 % of the full irradiance and were steadily low under 60 % of the full irradiance, indicating a low production of reactive oxygen species. Therefore, C. japonica thrived best under 60 % of the full irradiance.
