A aplicação exógena foliar de ácido abscísico desencadeia mecanismos de tolerância à deficiência hídrica em seringueira

Abstract: O ácido abscísico (ABA) é conhecido como o hormônio mais influente em desencadear mecanismos de tolerância a estresse em plantas, inclusive à deficiência hídrica. No entanto, o efeito da aplicação exógena como indutora de tolerância pré-estresse é pouco estudado em plantas de interesse agronômico. O objetivo deste trabalho foi avaliar o efeito do ABA sobre o desencadeamento de mecanismos de tolerância à deficiência hídrica em mudas de seringueira, cultivar RRIM 600. Foram usadas soluções nas concentrações 0, 5… Show more

“…9,10 In addition, in actual production and life, illegal addition is common and the misuse of plant growth regulators to accelerate the ripening of fruits and vegetables can pose risks to human health. 11,12 When the concentration of external application of ABA is greater than or equal to 10 À7 mol, it can inhibit the growth of stems, hypocotyls, roots, coleoptiles or leaves and other organs. 13 Hence, it is also urgent to monitor the content of illegally added ABA.…”
