对红松树皮和形成层的机械损伤，以及根部和茎内部边材的真菌渗透，导致边材受影响部分形成心材物质。纸色谱法揭示了受影响的边材中存在松酚（反式-3,5-二羟基-二苯乙烯）及其单甲醚（3-羟基-5-甲氧基-二苯乙烯）。正常未受损的边材不含有这些物质，这些物质只存在于心材中，但松木酚单甲醚除外，松木酚单甲醚也存在于树枝的髓中。对红松活枝边材在形成层受伤后松木酚的局部形成进行了现场和实验室实验。研究发现，松木酚是在生长季节后期和休眠季节形成的。树枝上伤口的横截面显示松西林呈三角形，以受伤的形成层为基础...
Mechanical damage to bark and cambium of red pine (Pinus resinosa Ait.), as well as fungal penetration of sapwood in the interior of roots and stems, induces the formation of heartwood substances in the affected parts of the sapwood. Paper chromatography disclosed the occurrence of pinosylvin (trans-3,5-dihydroxy-stilbene) and its monomethyl ether (3-hydroxy-5-methoxy-stilbene) in affected sapwood. Normal undamaged sapwood does not contain these substances, which were found to be restricted to the heartwood, except for pinosylvin monomethyl ether, which was found to occur also in the pith of branches.Field and laboratory experiments were carried out on the local formation of pinosylvins in the sapwood of live branches of red pine following wounding of the cambium. It was found that the pinosylvins are formed in the late part of the growing season and during the dormant season. Cross sections through the wound on branches showed the pinosylvins in a triangular pattern with the wounded cambium as a base lin...
