Relative importance of drying rate, desiccation tolerance and cryotolerance for the conservation of Ardlsla elllptlca, A. brunnescens and A. virens

摘要

The genus Ardisia is a pan-tropical genus of 400 ~ 500 species (Cheek et al 2012). However, due to overexploitation it is important to conserve the germplasm of this genus that has high horticultural and medicinal value (Yang et al 2001, Peng et al 2003). We investigated the feasibility and methods of cryopreservation for long-term seed storage in three Ardisia species—A. elliptica Thunb., A. brunnescens Walker, and A. virens Kurz.. We experimentally tested whether rapid desiccation can increase desiccation tolerance and promote cryotolerance, and whether slow thawing can increase the viability of cryopreserved seeds (Finch-Savage 1992).
