Resumo: The objective of the research was to evaluate the effect of different sources of silicon during the in vitro rooting phase of 'Maçã' banana tree by means of physiological, phytotechnical and ultrastructural analysis. It was used propagules already established in vitro which were inoculated in MURASHIGE & SKOOG (MS) medium, added of 30g L-1 of sucrose, 1mg L-1 of NAA (naphthalene acetic acid) and solidified with 1.8g L-1 of PhytagelTM. It was tested three sources of silicate added to MS medium, sodium silicate, potassium silicate and calcium silicate, at a dose of 1g L-1 and MS medium without silicate as a witness. The experimental design was completely randomized with fifteen replicates. The propagules were kept for 45 days in a growth room under controlled conditions. There was an increase in levels of chlorophyll a, b and total in the presence of calcium silicate. Supplementation of culture medium with sodium silicate promoted increase in length, fresh and dry weight of shoots. The silicon provides adequate seedling development.

Foram utilizados propágulos já estabelecidos in vitro e inoculados em meio MURASHIGE & SKOOG (MS), adicionado de 30g L-1 de sacarose, 1mg L-1 de ANA (ácido naftalenoacético) e solidificado com 1,8g L-1 de PhytagelTM. Foram testadas três fontes de silicato acrescidas ao meio MS, silicato de sódio, silicato de potássio e silicato de cálcio, na dosagem de 1g L-1 e o meio MS sem silicato como testemunha. O delineamento experimental foi o inteiramente casualizado, com quinze repetições. Os propágulos foram mantidos por 45 dias em sala de crescimento, sob condições controladas. Verificou-se aumento nos teores de clorofila a, b e total na presença de silicato de cálcio. A suplementação do meio de cultura com silicato de sódio promoveu aumento de comprimento, massa fresca e seca de parte aérea. O silício proporciona adequado desenvolvimento das plântulas.Universidade Federal de Santa Maria (UFSM)2019-11-20T20:53:40Z2019-11-20T20:53:40Z2011-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfASMAR, S.
