Efeito De Diferentes Concentrações De Aib E Procedências Geográficas No Enraizamento De Estacas De Paricá

Abstract: O objetivo deste trabalho foi determinar a influência da procedência e da concentração do ácido indol-3-butírico (AIB) no enraizamento de estacas provenientes de mudas de paricá. As procedências testadas foram: Belém-PA, Tucuruí-PA e Sinop-MT das quais foram obtidas sementes e produzidas mudas para obtenção de estacas. As estacas foram imersas em solução de AIB nas concentrações de 0, 2.000 e 3.000 ppm durante 10 segundos e plantadas em bandejas plásticas contendo vermiculita e fibra de coco como substrato (1:… Show more

“…The phenotypic variations between plants propagated via asexual result from the interaction between the genotypic effects, environmental effects and the "genotype x environment" interaction (Xavier et al, 2013). Therefore, there is a response based on genetic variability and adaptation to edaphoclimatic conditions, which are probably responsible for different internal compounds and concentrations between plant genotypes (Lima et al, 2018).…”

“…According to Lima et al (2018), the importance of working with seeds from different locations from a geographical and climatic point of view allows to verify the genetic differences within the species, and the phenotypic differences determined by environmental variations. Knowing the natural variability, individuals or materials that have superior characteristics can be selected, providing information on potential parents to be used in breeding programs (OHASHI et al, 2010).…”

“…O ácido-indol-3-butírico (AIB) é um regulador de crescimento, hormônio sintético, muito utilizado na propagação de mudas, trata-se de uma auxina altamente efetiva no estímulo ao enraizamento, devido à sua menor mobilidade, menor fotossensibilidade e maior estabilidade química na planta, acelerando o processo de emergência de primórdios radiculares, aumento no número e qualidade das raízes formadas (MAGEVSKI et al, 2011;LIMA et al, 2018). Entretanto, os resultados são variáveis a depender da espécie ou cultivar utilizada, da concentração e modo de aplicação do AIB, da época do ano, condições ambientais e do tipo da estaca, que mobiliza carboidratos e auxinas endógenas exercendo influência na sobrevivência e emissão de brotações (FACHINELLO et al, 1995;PONTES-FILHO et al, 2014).…”
