An acetylated galactoglucomannan from Picea abies L. Karst.
نویسندگان
چکیده
A water-soluble galactoglucomannan composed of D-galactose, D-glucose, and D-mannose in 1:3:17 mole proportion has been isolated from the secondary cell walls of Picea abies L. Karst. About 33% of the polysaccharide units were substituted by acetyl groups. Structural studies of the polymer indicated a beta-(1-->4)-linked glucomannopyranosyl backbone with a low content of branch points at O-6 of mannosyl and glucosyl residues. A preference for mannosyl groups indicates the presence of a single D-galactosyl unit side-chain. About half of the mannose residues were O-acetylated at C-2 and C-3 in 1.7:1 mole proportion.

Effects of Temperature and Season on In Vitro Establishment and Shoot Multiplication of Picea abies (L.) H. Karst
Plant propagation originated from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the removal of seasonal barriers, lower cost of production with higher yield wh...
متن کاملMoisture in Untreated, Acetylated, and Furfurylated Norway Spruce Studied during Drying Using Time Domain Nmr
Using time domain NMR, the moisture in Norway spruce (Picea abies (L.) Karst.) sapwood subjected to four different treatments (never-dried, dried and remoistened, acetylated, and furfurylated) was studied during drying at 40°C, at sample average moisture contents above fiber saturation. Spin-spin relaxation time distributions were derived from CPMG relaxation curves using multiexponential fitti...

The correlation between the peroxidase activity, chlorophyll and soluble protein content as well as the changes in vascular bundle structure in Norway spruce (Picea abies L. Karst.) needles affected by cement dust were studied. In spite of the absence of any yellowing symptoms, a significantly lower chlorophyll con tent was measured in spruce needles affected by cement dust. Observed sieve cel...
متن کاملMean canopy stomatal conductance responses to water and nutrient availabilities in Picea abies and Pinus taeda.
We compared sap-flux-scaled, mean, canopy stomatal conductance (GS) between Picea abies (L.) Karst. in Sweden and Pinus taeda (L.) in North Carolina, both growing on nutritionally poor soils. Stomatal conductance of Picea abies was approximately half that of Pinus taeda and the sensitivity of GS in Picea abies to vapor pressure deficit (D) was lower than in Pinus taeda. Optimal fertilization in...
