Morphophysiological changes in seedlings of two wood species after application of salicylic acid 1

[...]of its phenotypic plasticity, rapid dispersion and growth, the species has great adaptability to the most diverse habitats, including wet and dry, deep and shallow, clayey and sandy soils, as well as being found from sea level up to 2,000 m of altitude (Gilbert & Favoreto, 2011; Carvalho et al., 2013). Salicylic acid (SA) is an endogenous growth regulator that participates in physiological processes and acts on the plant resistance, promoting biological alterations and regulation of enzymes, in addition to being directly involved in plant protection (Rivas-San & Plasencia, 2011). Despite the great economic potential and superior quality of their wood, native woody species are little considered in commercial plantations when compared to exotic ones. [...]it is important that studies on the former species are carried out so that their use occurs in a balanced way with recommended species. According to Iapar and Köppen climate classification, local climate is considered Cfa, subtropical, with an average annual temperature between 22 °C and 23 °C, well distributed rainfall during the year and hot summers (Alvares et al, 2013; Nitsche et al, 2019).
