In vitro morphogenic response from zygotic embryos of Genipa americana

The aim of this study was to evaluate the in vitro morphogenic potential of genipap (Genipa americana L.) zygotic embryos. Seeds obtained from ripe fruits had their zygotic embryos excised and inoculated in MS medium with 4.44µM of 6-benzylaminopurine (BAP) and supplemented with 0.0; 1.07; 2.14 and...

Zusammenfassung:The aim of this study was to evaluate the in vitro morphogenic potential of genipap (Genipa americana L.) zygotic embryos. Seeds obtained from ripe fruits had their zygotic embryos excised and inoculated in MS medium with 4.44µM of 6-benzylaminopurine (BAP) and supplemented with 0.0; 1.07; 2.14 and 3.21µM of naphthalene acetic acid (NAA). The potential of explants regeneration and the shoot length and number of leaves in plantlets were evaluated. The in vitro regeneration of genipap is possible from the conversion of zygotic embryos in a MS medium with 4.44µM BAP supplemented with 3.21µM NAA. RESUMO: O objetivo do trabalho foi avaliar o potencial morfogênico in vitro de embriões zigóticos de jenipapeiro (Genipa americana L.). Sementes obtidas de frutos tiveram seus embriões zigóticos excisados e inoculados em meio MS com 4,44µM de 6-benzilaminopurina (BAP) suplementado com 0,0; 1,07; 2,14 e 3,21µM de ácido naftaleno acético (ANA). O potencial de regeneração dos explantes e o comprimento da parte aérea e o número de folhas nas plântulas formadas foi avaliado. Observou-se que é possível a regeneração in vitro de jenipapeiro a partir da conversão de embriões zigóticos em meio MS com 4,44µM de BAP, suplementado com 3,21µM de ANA.
