Determinar la viabilidad de las semillas de Gongora pseudopurpurea (Orchidaceae) almacenada ex situ

Abstract

Abstract: The Orchidaceae family, considered one of the most diverse and vulnerable due to increasing environmental stress, including habitat fragmentation, deforestation, exploitation of the species of this family for trade due to their beauty and variety of forms and colors. With this background, many species have been stored ex situ in seed banks. To confirm that the seeds are kept in good condition throughthis form of storage, the main objective of this work is established, which consists of verifying the viability status of the Gongora pseudopurpurea seeds, stored in the seed bank of the UTPL for 9 years. The results obtained in the Tetrazolium test do not clearly show that the seeds are viable, and it is observed that the majority of the embryo does not exist. That is why they are introduced in vitro to corroborate results. Three treatments will be used: T0 (MB control), T1 (MB plus coconut water), T2 (MBplus phytohormones); to test the germination of Gongora pseudopurpurea; obtaining zero germination.
