Photosynthesis-Involvement in Modulation of Ascorbate and Glutathione in <i> Euterpe oleracea</i> Plants Exposed to Drought

Boron Supply and Water Deficit Consequences in Young Paricá (<i>Schizolobium parahyba</i> var.<i> amazonicum</i>) Plants

“…The WUE was reduced by the effects of the B high and also water deficit, and this result occurred due to the water limitation causes severe dehydration in the mesophyll cells with negative consequences on essential processes as photosynthesis and transpiration (Barbosa et al, 2014), resulting in a decrease in WUE. Similar results were observed by Silva et al (2013a) working with Helianthus annuus, in which the plants showed a decrease in WUE, when in water deficit conditions.…”

“…Water deficit cause biochemical modifications such as oxidative stress and cell damages (Barbosa et al, 2014). Simultaneously, interferences on gas exchange like as stomatal closing and lower photosynthesis and respiration rates are detected (Tahkokorpi et al, 2007;Kiani et al, 2008).…”

Antioxidant system is insufficient to prevent cell damages in Euterpe oleracea exposed to water deficit

“…Interferences on growth plant also are detected on yield (Endres et al, 2010). Water supply is fundamental to keep the metabolic activity (Barbosa et al, 2014), nutrient absorption (Wang et al, 2011), gas exchange (Santos et al, 2009), and translocation of organic substances (Lobato et al, 2008).…”

Commercial and nutraceutical quality of grafted melon cultivated under hydric stress

“…Soil salinity, high solar radiation, nutrient deficits, low temperatures, and water stresses can be found among these changing conditions (Shao et al 2008). Water stress, in particular, can have a great impact on the agricultural yield and productivity (Ding et al 2017), as it is an important determinant in a plant's growth (Shao et al 2008) and development given that water participates in various metabolic and physiological functions within the plant such as photosynthesis-and in the hemicellulose, pectin, and lignin content (Barbosa et al 2014;Gall et al 2015).Mexico is a country considered with low water availability, thus, encouraging one to not only promote the efficiency of the resource in agriculture, but also to promote its use in a sustainable way (Salazar Moreno et al 2014), therefore, water is one of the concerns of the Mexican people, becoming a matter of national security (Rolland, Vega Cárdenas 2010), since, in addition to in agricultural activities, the use of pesticides is one of the most common practices and that put the soils and waters at risk, where they reach other areas by the runoff, infiltration and erosion of the soils in areas where they have been used (Hernández, Hansen 2011).The lack of water negatively affects processes such as the rate of photosynthesis, CO 2 fixation, and a decrease in the ribulose-1,5-bisphosphate carboxylase…”
