Autotoxicity and Allelopathy of 3,4-Dihydroxyacetophenone Isolated from Picea schrenkiana Needles [PDF]

open access: yesMolecules, 2011
Bioassay-guided fractionation of the diethyl ether fraction of a water extract of Picea schrenkiana needles led to the isolation of the phenolic compound 3,4-dihydroxy- acetophenone (DHAP). The allelopathic effects of DHAP were evaluated under laboratory

Variations in Stable Carbon Isotope Composition and Leaf Traits of Picea schrenkiana var. tianschanica along an Altitude Gradient in Tianshan Mountains, Northwest China [PDF]

open access: yesThe Scientific World Journal, 2014
To understand the morphological and physiological responses of leaves to changes in altitudinal gradients, we examined ten morphological and physiological characteristics in one-year-old needles of Picea schrenkiana var.

The complete chloroplast genome sequence of Picea schrenkiana (Pinaceae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2020
Picea is a phylogenetically complicate genus with great economic and ecological values. Here, we determined the whole complete chloroplast genome of Picea schrenkiana to provide genomic information for phylogenetic analysis of the genus.

Physiological effects of autotoxicity due to DHAP stress on Picea schrenkiana regeneration. [PDF]

open access: yesPLoS ONE, 2017
Picea Schrenkiana as one of the most important zonal vegetation was an endemic species in Middle Asia. Natural regeneration of P. Schrenkiana is a long existing problem troubling scientists. The autotoxicity of 3,4-dihydroxy-acetophenone (DHAP) was found

Soil Microbiome Drives Depth-Specific Priming Effects in Picea schrenkiana Forests Following Labile Carbon Input [PDF]

open access: yesMicroorganisms
The priming effect (PE), a microbially mediated process, critically regulates the balance between carbon sequestration and mineralization. This study used soils from different soil depths (0–20 cm, 20–40 cm, and 40–60 cm) under Picea schrenkiana forest ...

Molecular cytogenetic analysis of some Picea species from Eurasia and East Asia [PDF]

open access: yesВавиловский журнал генетики и селекции
Karyotypes of seven Picea species distributed across Eurasia and East Asia were analyzed using fluorescence in situ hybridization (FISH) and DAPI fluorescent staining. For P. meyeri and P.
