摘要: <正>用差示扫描量热仪(DSC)检测了杉木、马尾松种子细胞质冻结和玻璃化形成的温度,并分析了种子内含物成分与细胞质玻璃化形成的关系。结果表明:(1)杉木种子细胞质被检测到玻璃化状态的存在。其玻璃化状态形成的温度(Tg)为-52.386℃。杉木种子细胞质的冻结温度为-34.323C。马尾松种子细胞质未被检测到玻璃化状态的存在。其细胞质在24.826C的温度下结晶。(2)杉木种子粗脂肪含量低于马尾松种子。且杉木种子低聚糖/蔗糖的比值(O/D值)高于马尾松种子的O/D值。说明较低的脂肪含量和较高的低聚糖含量有制于细胞质玻璃化状态的形成。(3)含水量与细胞质玻璃化状态的形成关系不密切。

Abstract: The current situations of poplar plantation and industrial utilization were analyzed. Serious products with potential maketitability were pointed out, included laminated veneer lumber (LVL), cement formwork, composite flooring, fabircated thin veneer, baml3oo-poplar composite laminates, medium density fiberboard (MDF) with super-thickness, strawpoplar composite MI)F, low--density fiberboard and particleboard, oriented strandboard (OSB), wood/straw-plastics composites, poplar fibril wall block, and composition boards with recycled wood materials. Based on the analysis, the author give four suggestions: (1) controlling poplar wood resources; (2) developing non-formaldehyde adhesives; (3) investigating wood protection technologies; (4) enhancing technological innovation, education, patents, and standardlization.
