“…The interruption of growth rates due to water unavailability is a reflection of the absence of this preceptor, which is intimately involved with the processes of growth and differentiation (Shao, Chu, Jaleel, & Zhao, 2008;Osakabe, Osakabe, Shinozaki, & Tran, 2014), and it is a response that depends on the volume of water lost, dehydration rate, and duration of stress (Bray, 1997). Reductions in growth rates in response to water deficits have been observed in some species occurring in Caatinga, such as Erythrina velutina Willd (Fabaceae) (Silva, Silva, Nogueira, & Albuquerque, 2010;Oliveira, Dombroski, Medeiros, & Medeiros, 2016), Poincianella bracteosa (Tul.) L.P. Queiroz (Fabaceae), and Libidibia ferrea (Mart.…”
