The Amazon River prawn Macrobrachium amazonicum shows populations with four well-defined morphotypes in males. Dominant males of morphotypes green claw 1 (GC1) and green claw 2 (GC2) have large bodies and chelipeds and a ... -
Addition of silicon to boron foliar spray in cotton plants modulates the antioxidative system attenuating boron deficiency and toxicity
de Souza Júnior, Jonas P.; de M Prado, Renato ; ; Sousa Junior, Gilmar S. ; ; Cazetta, Jairo O. ; Gratão, Priscila L. (BMC Plant Biology, 2022) [Artigo]
Background: Boron (B) nutritional disorders, either deficiency or toxicity, may lead to an increase in reactive oxygen species production, causing damage to cells. Oxidative damage in leaves can be attenuated by supplying ... -
