“…Sugars contents are highly sensitive to environmental stresses (Rosa et al, 2009) and their accumulation consists of a defense mechanism of the plant to dehydration, adjusting the ionic and osmotic balance and maintaining the turgor of the cells (Marijuan & Bosch, 2013 ). Organic solutes accumulation under abiotic stresses conditions has been reported in several crops, such as cowpea (Sousa et al, 2015), pigeon pea (Monteiro, Cruz, Nardin, & Santos, 2014), tomato (Ganbari & Sayyari, 2018) and citrus (Zou, Wu, Huang, Ni, & He, 2013;Vives-Peris, Candeas, & Clementes, 2017). Other adaptive responses to water deficit may occur simultaneously, as changes in gas exchange and nitrate reductase enzyme activity, limiting nitrogen assimilation (Alguacil, Caravaca, Díaz-Vivancos, Hernández, & Roldán, 2006).…”
