Abstract Pinus koraiensis is the dominant and constructive species of the zonal vegetation in Northeast China, known as the mixed broadleaf-Korean pine forest. Although carbohydrate metabolism pathways in the seed embryo are known to play crucial roles during seed dormancy and germination in P. koraiensis, it remains unclear whether these metabolic pathways function differentially across tissues. P. koraiensis seeds that had undergone different durations of moist chilling in their natural environment, yielding seeds with relatively deeper primary physiological dormancy (DDS) and seeds with released primary physiological dormancy (RDS). A non-targeted metabolomic analysis was conducted on the radicle and hypocotyl-cotyledon… More >

Abstract Korean pine is an important afforestation tree species in Northeast China, which has a high ecological and economic value. Although regeneration of somatic embryogenesis using immature zygotic embryos of Korean pine as explants has been successful, it cannot be applied to automation and large-scale production. Therefore, we urgently need a method that can increase the output of somatic embryos (SEs) to meet the needs of large-scale production. We used Korean pine 1–1 and 1–100 cell lines as research materials to evaluate the effects of inoculum-density, culture time, orbiting speed, vessel volume, plant growth regulator (PGR)… More >

Abstract Genetic parameters were evaluated for growth and cone characteristics (tree height, diameter at breast height, volume, cone number, thousand seeds weight and single cone seeds weight) on 86 half-sib families of Pinus koraiensis aged 31 years. Analyses of variance revealed significant differences (p < 0.001) in all growth and cone traits among families while no significant differences were detected among blocks and the interaction between blocks and families. The average family values for growth traits were 17.22 m, 8.67 cm and 0.43 m3 for tree height, diameter at breast height and volume, respectively. The average cone… More >
