Cryopreservation of Forest Tree Seeds: A Mini-Review

Abstract

Since forest trees form the basis of forest ecosystem, their prolong subsistence is crucial for various flora and fauna. The foremost challenges to sustain the forest ecosystem comprise of the declining forest tree population accompanied with structural changes due to afforestation and exploitation of forest area, environment changes, pests, pollution, and introgressive hybridization. For ex situ conservation approach, in vitro techniques encompass basic role for conserving tree genetic resources, predominantly where natural propagules like recalcitrant seed might not be appropriate for long-term conservation. The practice includes restricted growth techniques, conventional micropropagation, production and storage of synthetic seeds, and cryopreservation. Even though these practices have been applied chiefly to herbaceous species, but recently, woody species were also focused upon. Key conceptions, challenges and techniques for forest tree seed conservation are discussed briefly in this review with special emphasis on some successful cryopreservation approaches for long-term storage.

VIABILIDAD Y GERMINACIÓN DE SEMILLA DE Cordia elaeagnoides A. DC.

“…Existen factores como la disponibilidad de nutrientes, temperatura, presencia de plagas, enfermedades, disposición genética o humedad, que intervienen en la maduración de semillas. En particular, elevados porcentajes de humedad durante el desarrollo de la semilla podrian mejorar la viabilidad y capacidad de almacenamiento (Gantait, Kundu, Wani, & Das, 2016;Pammenter & Berjak, 2014). v.g.…”
