Biochemical Aspects of the Spiral Grain Formation in Scots Pine (Pinus Sylvestris L.) Wood. Some Differences and Similarities with Biochemical Indicators of Abnormal Xylogenesis in Karelian Birch (Betula Pendula Roth Var. Carelica (Mercl.) H ämet-Ahti)

CONCLUSION: The study showed that the differences in the AOS enzyme's activity in P. sylvestris during the formation of straight-grained and spiral-grained wood were revealed for the first time. The increased CAT, POD and PPO activities in xylem with a decrease in SS and an increase in ApInv during spiral-grained wood formation can be biochemical markers of these structural anomalies. Metabolic regularities found in the AOS enzyme complex during spiral-grained wood formation do not contradict those found earlier during figured wood formation in B. pendula var. carelica. The identified patterns can form the base for diagnostics of P. sylvestris wood quality in forest seed plantations and in their natural growth, which is necessary both for fundamental science and in various industry areas while high-quality material harvesting.PMID:37622712 | DOI:10.2174/0929866530666230824101841
