RIOS-GARCIA, Carlos Alberto; ORANTES-GARCIA, Carolina; MORENO-MORENO, Rubén Antonio  e  FARRERA-SARMIENTO, Óscar. Effect of storage on the viability and germination of two tropical tree species. Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.13, pp.103-109. ISSN 2007-901X.  https://doi.org/10.19136/era.a5n13.1161.

Cochlospermum vitifolium (Willd.) Spreng. and Quararibea funebris (La Llave) Vischer are tropical trees native to Mexico with ecological, social and economic importance; however, there is no sustainable management practice for these species. The objective was to evaluate viability and germination in seeds stored at 0, 3, 6, 9 and 12 months. The seeds at 0 months of storage were 99.66 and 99.33% viable for C. vitifolium and Q. Funebris, respectively, while at 12 months there was a decrease in viability, exhibiting a final germination of 71.3% for C. vitifolium and 61.3% for Q. Funebris.
