Propagação vegetativa de Platanus acerifolia Ait: (II) efeito da aplicação de zinco, boro e ácido indolbutírico no enraizamento de estacas

Abstract: O objetivo desse trabalho foi avaliar os efeitos da aplicação do zinco (Zn), boro (B) e ácido indolbutírico (AIB) no enraizamento de estacas de Platanus acerifolia Ait. Os tratamentos consistiram do condicionamento das estacas, coletadas em quatro épocas ao longo do ano e representando diferentes tipos fisiológicos, com: sulfato e cloreto de zinco (0, 2,5, 5, 10, 20 e 40mg l-1 Zn), ácido bórico (0, 50, 100, 150, 200 e 250mg l-1 H3BO3) e ácido indolbutírico (0, 20 e 40mg l-1 AIB), através de solução aquosa, pel… Show more

“…The amount of primary roots produced by L. elegans, C. glabratus, and T. australis was significantly higher in the late winter/spring. These results corroborate studies by Nicoloso et al (1999) and Pizzatto et al (2011), who found higher primary root production in spring when compared to autumn and winter in studying the vegetative propagation of Platanus acerifolia and Hibiscus rosa-sinensis at different seasons/periods of the year. For these authors, the production of primary roots in live cuttings may be linked to the endogenous content of indoleacetic acid (IAA) and to the temperature during the experiment.…”

“…According to the same authors, temperature has a direct effect on plant metabolism, and the higher the temperature, the more accelerated the chemical reactions will be, which may have favored the better root development during the spring. According to Nicoloso et al (1999), the low root production in autumn is possibly associated with lower temperatures and a high content of inhibitors, common in the dormancy phase.…”

“…O período de coleta dos ramos após a aplicação do zinco foi determinado conforme Nicoloso et al (1999). Sete dias após a aplicação do zinco, foram coletados ramos de umbuzeiro com 3 a 4 mm de diâmetro e aproximadamente 30 cm de comprimento.…”

“…A aplicação de zinco nas plantas matrizes antes da coleta das estacas pode aumentar o percentual de enraizamento (Nicoloso et al, 1999), no entanto, em Spondias não há trabalhos evidenciando o efeito do tratamento de planta matriz, especialmente com zinco.…”
