·简介在柳杉中，心材性质被认为受到特定提取物的影响。目前尚不清楚特定心材化合物的性状是否受遗传控制。方法采用29 C.研究了海棠无性系的无性系变异和无性系重复性。结果两种降木脂素的含量及其组成（S）mol/（（A）mol +（S）mol）随克隆的不同而有显著差异，提示降木脂素的生物合成受基因调控。日本。特别是，Sequirin C的克隆重复性高于沉香脂素和总降木脂素含量。此外，去甲木脂素摩尔比的克隆重复性相当高。这些结果表明，遗传参与是更大的积累红杉C比agatharesinol。没有显着的相关性被发现之间的agatharesinol和sequirin C的含量，或之间的总norlignan含量和norlignan摩尔比，表明在norlignan生物合成中的agatharesinol和sequirin C的形成是独立控制的inC。日本。结论山茱萸心材提取物去甲木脂素的性状受遗传控制。日本的。
•IntroductionInCryptomeria japonica, heartwood properties are considered to be affected by specific extractives. It remains unclear whether traits of specific heartwood compounds are under genetic control.•MethodsTwo major heartwood norlignans, agatharesinol (A) and sequirin C (S), were determined quantitatively and qualitatively in 29C. japonicaplus-tree clones to evaluate their clonal variations and clonal repeatability.•ResultsThe content of two norlignans and their composition (S)mol/((A)mol + (S)mol) varied significantly depending on the clone, suggesting that the biosynthesis of norlignan is genetically regulated inC. japonica. In particular, the clonal repeatability of sequirin C was higher than that of both agatharesinol and total norlignan content. In addition, the clonal repeatability of the norlignan molar ratio was quite high. These results suggested that genetic involvement is greater in the accumulation of sequirin C than agatharesinol. No significant correlation was found between agatharesinol and sequirin C content, or between the total norlignan content and the norlignan molar ratio, suggesting that the formation of agatharesinol and sequirin C in norlignan biosynthesis is independently controlled inC. japonica.•ConclusionsIt was suggested that the traits of the specific heartwood extractive norlignans were under genetic control inC. japonica.
