Recovery trends and predictions of Fraser fir (Abies fraseri) dynamics in the Southern Appalachian Mountains [PDF]

Canadian Journal of Forest Research, 2017
The endemic Fraser fir (Abies fraseri (Pursh) Poir.) is found in only seven montane regions in the southern Appalachians above ca. 1500 m elevation. Due to widespread insect-caused mortality from the invasive balsam woolly adelgid (Adelges piceae Ratzeburg), as well as possible impacts from climate change and atmospheric pollution, the future of ...

HYBRIDIZATION RESULTS USING THE HYBRID Abies cilicica × Abies cephalonica

Acta Scientiarum Polonorum: Hortorum Cultus, 2014
Abies fraseri (FF) is a North American conifer which is crucial for growers of Christmas trees. This species suffers 100% mortality after infection of root rot caused by Phytophthora cinnamomi. The hybrid material A. cilicica × A. cephalonica (CZ) and A.

Stage-Specific Responses to Warming in Trojan Fir Across Early Life Stages: Germination, Seedling Survival, and Seedling Growth. [PDF]

Ecol Evol
We investigated the effects of temperature, cold stratification, and light on germination and early seedling growth in Abies nordmanniana subsp. equi‐trojani (Trojan fir), an endangered endemic tree from northwestern Anatolia (Türkiye). Our results show that while higher fixed and alternating temperatures enhance germination, they also lead to ...

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm. [PDF]

Appl Plant Sci
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Aging and longevity in decades-old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays. [PDF]

Am J Bot
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Commodity risk assessment of debarked conifer wood chips fumigated with sulfuryl fluoride from the US. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to deliver a risk assessment on the likelihood of pest freedom from regulated EU quarantine pests, with emphasis on Bursaphelenchus xylophilus and its vectors Monochamus spp. of debarked conifer wood chips fumigated with sulfuryl fluoride as proposed by the United States (US) and

Recent results of Czech-American fir hybridization research

Journal of Forest Science, 2013
Fraser fir (Abies fraseri) Christmas tree plantations in North Carolina are infested by root rot caused by Phytophthora cinnamomi. This disease kills almost 100% of Fraser fir material and leaves the soil permanently infested.

Recent fir hybridization research in the light of Czech-American cooperation

Journal of Forest Science, 2009
The project is based on control pollination of different fir species in the sense of interspecific hybridization. The aim of this procedure is a new bred material for specific needs of forestry and Christmas tree production.
