用已知树龄树木的茎盘测定了总状Laguncularia racemosa生长轮的周期性，并描述了这些生长轮的解剖学特征。在显微镜检查中，生长轮几乎不明显，但在宏观上可以很好地区分，具有交替的浅棕色和深棕色层。交叉定年分析表明，在L.总状花序。L.年生长轮的存在。总状花序的研究表明，它可能在树木年代学方面具有巨大潜力，并应鼓励对红树林动态进行与年龄有关的研究。这些研究对于评估气候变化对红树林生态系统的影响以及分析气候变化对植物群落的影响可能很重要。
Stem discs from trees of known age were used to determine the periodic nature of the growth rings formed inLaguncularia racemosaand to describe the anatomical features of these rings. The growth rings were scarcely distinct on microscopic examination, but they were well distinguishable macroscopically, with alternating light brown and dark brown layers. Cross-dating analysis revealed the occurrence of annual growth rings inL. racemosa. The existence of annual growth rings inL. racemosasuggests that it may have great potential for dendrochronology and should encourage age-related studies on the dynamics of mangrove forests. These studies can be important for the evaluation of climate change impact on mangrove ecosystems, as well as for the analysis of effects related to climate variability on plant communities.
