“…In comparison, seeds of P. balsamifera L. from Bowness (United States) deteriorated after 4 months of storage at 21-24°C (Hellum 1973). Similar results were obtained by Maroder et al (2000) for Salix alba and Salix matsudana. A complete loss of germination was observed after 2 weeks of storage at 25°C.…”

“…1). Contradictory to our results, seeds from S. alba lose viability after 5 months of storage at −20°C (Maroder et al 2000). The present study also compared the effect of cryopreservation on seed viability.…”

“…Similar results were obtained in studies examining the effect of thermal conditions on seed viability of S. alba and S. matsudana. Storage at lower temperatures resulted in higher levels of germination in both species (Maroder et al 2000).…”

“…In the presented study, we demonstrate that seeds of P. nigra maintain high levels of germination even after 2 years of cryostorage. Maroder et al (2000) reported that 11 months of cryostorage did not adversely impact the germination of S. matsudana seeds. Pence (1996) reported on the cryopreservation of Populus deltoides.…”

“…Tolerance to desiccation and LN exposure of over a dozen Populus and Salix species was investigated (Hong et al 1998;Maroder et al 2000;Popova et al 2012Popova et al , 2013Pence 1996;Hill et al 2013). Most of them (30 species) were considered as orthodox (Hong et al 1998;Maroder et al 2000), and some of them (P. tremuloides and P. deltoides) were characterized as intermediate (Pence 1996;Hill et al 2013).…”

Desiccation tolerance and cryopreservation of seeds of black poplar (Populus nigra L.), a disappearing tree species in Europe

et al. 2014

Black poplar (Populus nigra L.) is a widely distributed species that plays a crucial role in riparian forest ecosystems. Due to a reduction in its natural habitats and hybridization with introduced poplar species clones, its genetic pool is decreasing and efforts are required to preserve this species. Seeds of black poplar are short-lived and quickly lose viability during conventional storage in gene banks. Therefore, in order to preserve ex situ the genetic diversity of this species, the feasibility of seed cryopreservation in liquid nitrogen (at -196°C, LN) for periods of 24 h and 2 years was investigated. Seeds were harvested from three individual trees (two provenances) and desiccated to different levels of water content (WC) in the range of 0.02-0.35 g g -1 (g H 2 O/g dry mass, g g -1 ) prior to immersion in LN. Seed germination was assessed after each treatment. P. nigra seeds tolerated desiccation to WC 0.07 g g -1 but after severe desiccation to WC\0.05 g g -1 exhibited a significant reduction in germination. Results indicated that all black poplar seeds, regardless of origin, year of harvesting and seed quality, could be cryopreserved for 24 h when their WC was in the range of 0.11-0.17 g g -1 . Physiology of P. nigra seeds showed in this paper is consistent with attributes of intermediate seed storage behavior. This study provides a foundation for using cryopreservation for the ex situ conservation of P. nigra seeds.

Salix dormant bud cryotolerance varies by taxon, harvest year, and stem‐segment length

Willow (Salix L.) species have good qualities for becoming a biomass crop for production of biofuels. They grow on marginal soils, produce high yields of wood in a short period of time, and are easily propagated. Salix is one of the few genera that may be cryopreserved as dormant winter buds (DBs) instead of using tissue culture techniques. The objective of our study was to evaluate selected factors that affect cryotolerance of nine Salix germplasm accessions in the USDA-ARS National Plant Germplasm System collection. One-year-old branches harvested in January over 3 yr were cut into either 6-to 7-or 10-cm segments containing at least two DBs. Segments were treated with a slow-cooling procedure and stored in vapor-phase liquid N (LNV). Control segments were stored at −5 °C until planting. The LNV-exposed and the −5 °C-stored nodal segments were warmed and directly planted in a cold greenhouse. Six weeks later, the material was evaluated for shoot and root development. Segments that developed a shoot were considered viable. Average viability varied among years (0-35.1%) even for the same accession, species (4.2-51.4%), and segment length. Dormant buds on 10-cm segments had higher average viability (82.2%) than did DBs on 6-to 7-cm segments (43.9%), suggesting higher suitability for cryopreservation. In the material studied, Salix DB viability was correlated with branch diameter, DB density, and the ability to develop shoots and roots prior to cryopreservation.
