An acetylated galactoglucomannan from Picea abies L. Karst.
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...
متن کاملRecovery of photosynthesis in 1-year-old needles of unfertilized and fertilized Norway spruce (Picea abies (L.) Karst.) during spring.
Photosynthetic O(2) evolution and chlorophyll a fluorescence were measured in 1-year-old needles of unfertilized and fertilized trees of Norway spruce (Picea abies (L.) Karst.) during recovery of photosynthesis from winter inhibition in northern Sweden. Measurements were made under laboratory conditions at 20 degrees C. In general, the CO(2)-saturated rate of O(2) evolution was higher in needle...
متن کاملEffects 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 کاملIdentification of Salt Stress Biomarkers in Romanian Carpathian Populations of Picea abies (L.) Karst.
The Norway spruce (Picea abies), the most important tree species in European forests, is relatively sensitive to salt and does not grow in natural saline environments. Yet many trees are actually exposed to salt stress due to the common practice of de-icing of mountain roads in winter, using large amounts of NaCl. To help develop strategies for an appropriate use of reproductive seed material o...
