心材型花斑木形成机理的研究

花斑木的形成原因国内外一直认为是真菌分泌黑色素形成的菌纹。申请者根据木材花斑是在树木心材部位，无腐朽且无真菌存在，花斑贯穿整个树干的特征，原有真菌花斑木理论无法解释这类心材无真菌型花斑木的形成机理。因此本研究提出“细菌型花斑木”的科学假说，开展心材型花斑木树种调查、木材解剖学研究，将通过微生物分离培养及生物高通量测序、将可能细菌接种于未产生花斑的立木上进行试验，分析研究无真菌心材型花斑木的形成是否与细菌的诱导有关？. 本研究主要研究目标是解明心材型花斑木中色素的分布、迁移、积累规律，确定心材型花斑木对材性的影响及花斑色素的主要成分，形成心材花斑木有效菌种的分离和种类的鉴定，验证“细菌型花斑木”假说，阐释心材型花斑木形成机理。. 本研究从另一观点探究花斑木的形成机理，以希有效地控制腐朽和促进花斑的形成，为多种类型的花斑木的人工培育奠定理论基础

The reason of the formation of spalted wood is always believed to be the fungus secreting melanin.According to the applicant, the wood grain is located in the heartwood part of the tree, and there is no rot and fungus. The grain runs through the whole trunk. The original fungus theory cannot explain the formation mechanism of this kind of heartwood non-fungus spalted wood. This study proposed "bacteria type spalted wood" scientific hypothesis, to carry out the heartwood type survey spalted wood tree species, wood anatomy study, microorganism cultivation and high-throughput sequencing, bacteria inoculation on normal trees, analysis and study the formation of heartwood without fungi type spalted wood is associated with the induction of bacteria?. The mainly target of this research is interpret heartwood type grain distribution, migration and accumulation regularity of the pigment in wood, determine the heartwood type grain on the impact of material and the main components of grain pigment form heartwood grian no separation of the effective strain and species identification, verification "bacteria type spalted wood" hypothesis, heartwood type spalted wood formation mechanism.. From another point of view, this study explored the formation mechanism of heartwood type spalted wood in order to effectively control decay and promote the formation of spalted wood and lay a theoretical foundation for the artificial cultivation of various types of spalted wood.
