ENRAIZAMENTO EX VITRO E ACLIMATIZAÇÃO DE MICROESTACAS DE Ilex paraguariensis A. St Hil.

Abstract: ENRAIZAMENTO EX VITRO E ACLIMATIZAÇÃO DE MICROESTACAS DE Ilex paraguariensis A. St Hil.RESUMO: A técnica de microestaquia e enraizamento ex vitro pode resultar em mudas com o sistema radicular de melhor qualidade e com maior número de raízes secundárias, quando comparada com a estaquia convencional. O objetivo deste trabalho foi avaliar o enraizamento ex vitro e a aclimatização de microestacas de erva-mate em diferentes doses do fitorregulador ácido 3-indolibutírico (AIB) e substratos. Em sala de cultivo foi a… Show more

“…We observed root and callus formation on the same cutting for all evaluated lengths, ranging from 22.5% to 83.7% for cuttings of 12 cm and 10 cm, respectively (Table 2). Although other authors have discussed callus formation as a detrimental effect on rooting of yerba mate cuttings (TRONCO et al, 2015), we found that the presence of callus was not harmful for adventitious rooting, since treatments with highest rooting percentages presented callus formation. Further, it is important to emphasize that callus presence is not a determining condition for root formation, which may be a characteristic of each species (STUEPP et al, 2013).…”

“…Overall, the stem cuttings used in this study were satisfactory for yerba mate, as observed by other authors (KRATZ et al, 2015;TRONCO et al;STUEPP et al, 2015STUEPP et al, , 2017aSTUEPP et al, , 2017b. The percentage of rooted cuttings ranged from 22.50% to 86.25% among the different treatments.…”

“…A emissão de novos brotos foi maior nas miniestacas provenientes do clone EC40 e, quando houve influência das doses de N, as maiores médias foram observadas nos tratamentos com as menores doses deste nutriente. As porcentagens de brotações de ambos os clones foram similares às observadas por Tronco et al (2015) ao avaliar microestacas de erva-mate. As porcentagens abaixo de 30 % para novas brotações podem estar relacionadas à disponibilidade energética das miniestacas, priorizando o uso de carboidratos no processo de rizogênese em detrimento da produção de brotos.…”
