Induction of somatic embryogenesis in excised cotyledons of Picea glauca and Picea mariana

open access: yes, 1990
L'embryogenèse somatique a été obtenue à partir de cotylédons chez Picea mariana (Epinette noire) et Picea glauca (Epinette blanche). Le traitement des cotylédons en présence d'un rapport élevé (90 : 1) en benzyladénine (BA): acide napthalène acétique (ANA), une semaine avant une mise en culture sur un milieu dont le rapport auxine: cytokinine est soit

A fungal endophyte of black spruce (Picea mariana) needles is also an aquatic hyphomycete [PDF]

open access: yesMolecular Ecology, 2006
AbstractAn aquatic hyphomycete, Dwayaangam sp., was isolated from superficially sterilized black spruce (Picea mariana) needles submerged in aerated water in a small glass chamber (microcosm). The internal transcribed spacer (ITS) sequence of this fungus and of a commonly encountered foliar endophyte isolated from P.

Role of green alder in boreal conifer growth: competitor or facilitator?

open access: yesFACETS, 2021
Sustainable forest management implies successful regeneration after disturbances. Low N availability and competition can, however, limit tree establishment in boreal ecosystems.

Assembly and Annotation of Red Spruce (Picea rubens) Chloroplast Genome, Identification of Simple Sequence Repeats, and Phylogenetic Analysis in Picea [PDF]

open access: yes, 2022
We have sequenced the chloroplast genome of red spruce (Picea rubens) for the first time using the single-end, short-reads (44 bp) Illumina sequences, assembled and functionally annotated it, and identified simple sequence repeats (SSRs).

Contribution of topographic features and categorization uncertainty for a tree species classification in the boreal biome of Northern Ontario

open access: yesGIScience & Remote Sensing, 2023
Variations within local topography can effectively impact the location of tree species within naturally forested areas. Furthermore, the uncertainty of prediction for classification can vastly differ amongst topography and the overlying tree species ...

Highly informative single-copy nuclear microsatellite DNA markers developed using an AFLP-SSR approach in black spruce (Picea mariana) and red spruce (P. rubens). [PDF]

open access: yesPLoS ONE, 2014
Microsatellites or simple sequence repeats (SSRs) are highly informative molecular markers for various biological studies in plants. In spruce (Picea) and other conifers, the development of single-copy polymorphic genomic microsatellite markers is quite ...
