The seed viability test was performed using 1 % tetrazolium (2,3,5-triphenyl tetrazolium chloride) during three staining times and the percentage of viability and vigor levels were considered according to the topological staining pattern. Germination speed, germination capacity, and morphological indices of plant quality were determined using the aboveground belowground ratio, slenderness, degree of lignification and Dickson's quality. The highest percentage of viable seeds with the maximum staining time (3 hours) was verified. The medium vigor category was higher in the three species, as determined by a partial reddish staining pattern as an expression of their physiological quality, which was reflected in the response to germination. The morphological quality indices allowed us to identify the species’ potential for growth and development for acclimatization to the area. The correspondence analysis was significant (p≤0.05), which facilitated the formation of quality groups, C. cateniformis was found to be of a high-enough quality as an indicator of its potential to cover restoration needs in Amazonian conditions. 2023 artículo científico 1390-6542 https://www.redalyc.org/articulo.oa?id=572273150002 https://www.redalyc.org/journal/5722/572273150002/ https://www.redalyc.org/journal/5722/572273150002/html/ https://www.redalyc.org/journal/5722/572273150002/572273150002.epub https://www.redalyc.org/journal/5722/572273150002/movil https://doi.org/10.29019/enfoqueute.890 en http://www.redalyc.org/revista.oa?id=5722 Enfoque UTE application/pdf Universidad UTE Enfoque UTE (Ecuador) Num.1 Vol.14 |
