Micropropag. VL - 17 IS - SE - DO - 10.46526/pccm.2021.v17.167 UR - http://pccm.ufla.br/index.php/plantcellculturemicropropagation/article/view/167 SP - 17:e167 AB - <p>The propagation of gabiroba occurs via sexual reproduction. However, their seeds are recalcitrant. The objective of this study was to evaluate the physiological quality of <em>Campomanesia</em>&nbsp;<em>adamantium</em>&nbsp;and <em>C. pubescens</em>&nbsp;seeds, sown in a growth medium with different sucrose concentrations, to understand the performance of these species in an <em>in vitro</em>&nbsp;environment. An entirely randomized design was used in a 2x4 factorial scheme [2 species and 4 doses of sucrose (0, 20, 40 and 80 g L<sup>-1</sup>)]. The following were evaluated: germination, growth emergence and parameters and development of seedlings. The presence of sucrose in the culture environment did not improve the germination percentage. <em>C. adamantium</em>&nbsp;seeds germinated in supplemented environment with up to 20 g L<sup>-1</sup>&nbsp;showed higher emergence and vigor and considerable increase in the number and length of the roots. For <em>C. pubescens</em>, the culture environment without the addition of sucrose provided better results.</p> ER -
