Soluble sugars and cell wall of the seeds of the black willow (Salix nigra Marsh) and the black poplar (Populus nigra L.)

Seeds of Salix nigra and Populus nigra were stored at 25 °C. After 6 days normal germination dropped to 4%. Soluble carbohydrates were determined by HPAEC-PAD in fresh and stored seeds of the two species. Sucrose was the main sugar with much lesser amounts of glucose and fructose and a peak of oligo...

Seeds of Salix nigra and Populus nigra were stored at 25 °C. After 6 days normal germination dropped to 4%. Soluble carbohydrates were determined by HPAEC-PAD in fresh and stored seeds of the two species. Sucrose was the main sugar with much lesser amounts of glucose and fructose and a peak of oligosaccharide was detected, which was purified by gel permeation chromatography. Analysis of the monosaccharide components and of the NMR spectra showed that it was constituted by α-L-arabinofuranose, β-D-xylopyranose and uronic acid, and it was esterified by a phenolic acid. Analysis of the cell wall monosaccharide constituents was performed on fresh and stored seeds. Arabinose was the main sugar, with galactose, xylose, glucose, rhamnose and uronic acid also present. The content of these monosaccharides did not significantly vary on storage. 2002 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_03650375_v89_n1-2_p29_Lima http://hdl.handle.net/20.500.12110/paper_03650375_v89_n1-2_p29_Lima
