“…There was an antagonistic relationship between the rooting and callus formation, suggesting that these processes compete for assimilates, since the greatest rooting responses generally occurred in treatments with lower callus formation (Tables 1 and 2). A similar result occurred in study on micropropagation of erva mate, where an inverse relation was observed between rooting of apical cuttings and callus formation (HORBACK et al, 2011). With regard to the effect of substrate on callus formation, the fact that there was decreased callus formation when erva mate cuttings were grown in sand indicated the superiority of this substrate, since the absence of calli has been cited as a factor in the formation of adventitious roots (MACHADO et al, 2013).…”

“…Já, para o explante plúmula da espécie em estudo, os dados divergem dos reportados por Horbach et al (2012), que obtiveram Figura 1. Percentagem de regeneração obtidos de explante de embriões zigóticos inteiro ( ) e plúmula ( ) de mulungu em função dos concentrações de BAP após 30 dias de inoculação em meio WPM ( NS Não significativo a 5% de probabilidade pelo teste F).…”

“…As condições do ambiente exercem um papel fundamental no enraizamento e na aclimatização das microestacas, sendo a faixa ideal de temperatura entre 25 e 30°C e umidade relativa do ar acima de 80% (GOULART; XAVIER, 2008). Na microestaquia, a aclimatização se dá na sala de cultivo (HORBACH et al, 2011) ou em câmara úmida em casa de vegetação, no entanto não há registros de trabalhos que relacionem o ambiente com diferentes substratos no enraizamento ex vitro e na aclimatização de microestacas de erva-mate. O objetivo deste trabalho foi avaliar o enraizamento ex vitro e a aclimatização de microestacas de erva-mate sob diferentes doses de ácido 3-indolibutírico e substratos.…”
