Biosaline production of seedlings of native species from the Caatinga dry forest

Abstract: The Caatinga dry forest species are well adapted and resilient to the climatic conditions of the Brazilian semiarid region. However, this is one of the more vulnerable ecosystems to climate change, due to increasing deforestation and drought in the last years. Water shortage in this region has prompted studies into the possibility of safe brackish water use/reuse for forage and forest seedling production. We tested, in this study, alternative sources to potable water to irrigate forest seedlings in nurseries, … Show more

“…This generally translates into changes in the proportion of root growth as a function of the area, which is usually interpreted as xeromorphic behavior. This can guarantee a greater uptake of water resources in the deepest layers of the soil as well as better management of the transpiring surfaces (Ferreira et al, 2015;Dantas et al, 2020). Thus, although C. glaziovii is a species widely occurring in the semi-arid landscapes of the Caatinga, it does not seem to use this strategy of reversing patterns to deal with disturbances occurring in its place of occurrence.…”

“…Several findings in the literature have been discussing the most varied strategies that plants occurring in arid and semi-arid environments are used to withstand this recurrent disturbance (Silva et al, 2013;Gratani, 2014;Amissah et al, 2018;Santos Júnior et al, 2020;Ribeiro et al, 2020). Some changes in growth patterns such as reduced number of leaves and leaf area , investments in a more robust root system (Dantas et al, 2020) and, consequently, increase in the root/shoot ratio (Ferreira et al, 2015) have been interpreted as important morphological transformations that guarantee greater survival in these environments (Santos Júnior et al, 2020).…”

“…Um dos problemas que mais reduz a qualidade da água é o excesso de sais presentes, tanto nas águas superficiais como subterrâneas, sendo recorrente, sobretudo, em regiões áridas e semiáridas em virtude das irregularidades das chuvas e da elevada taxa de evapotranspiração e, nessa ocasião verifica-se o acúmulo de sais tanto nas águas como também no solo em quantidades desvantajosas ao desenvolvimento das plantas (Nogueira et al, 2012). Vale ressaltar que a salinidade pode suceder-se também pela condução inadequada do solo e da água em áreas agrícolas, como por exemplo, a drenagem insuficiente e o uso incorreto de fertilizantes (Dantas et al, 2019).…”

“…Paralelamente aos problemas de salinidade nas águas e no solo, existem os inconvenientes advindos do desmatamento, ocasionados principalmente pelo desordenado crescimento da agricultura e pela exploração inadequada dos recursos florestais, como exemplo a madeira. É o caso do domínio vegetal Caatinga, floresta tropical seca, que vem sofrendo ao longo dos anos diversas intervenções humanas e com isso a vegetação típica do Semiárido se encontra com menos de 50% de sua cobertura original (Dantas et al, 2019).…”

“…However, this type of water from sh farming is usually saline and, depending on the management, can hamper crop growth and production. The selection of salinity-tolerant species is the main practice used to ensure pro table crops when the goal is to take advantage of saline e uents as a water and nutritional source for agricultural crops and, when there is availability, the e uent can also be diluted to reduce electrical conductivity and attenuate salt stress (Dantas et al 2019).…”
