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 ...

Vegetative Propagation of Abies fraseri by Stem Cuttings1

HortScience, 1980
Abstract Rooting of Fraser fir [Abies fraseri (Pursh) Poir.] stem cuttings decreased as stock plant age increased from 5 to 12 to 22 years. Indolebutyric acid (IBA) at 5000 ppm increased rooting of cuttings from 12- and 22-year old trees.
