摘要
Piper mollicomum Kunth(胡椒科)在保护巴西大西洋森林方面发挥着至关重要的作用,有助于森林砍伐地区的再生。最近的科学研究分析了多种胡椒精油(EO)的化学成分和季节动态,强调了阐明其化学生态相互作用的必要性。本研究旨在以 P. mollicomum 为模型,扩展新热带森林中这一重要分类群的化学生态知识。采用的方法包括收集植物材料、通过水蒸馏提取环氧乙烷、通过气相色谱-质谱联用仪(GC-MS)和气相色谱-火焰离子化检测器(GC-FID)分析环氧乙烷、记录潜在授粉者的访问频率和微气候变量,以及计算化学多样性和化学遗传指数。化学分析结果表明,环氧乙烷的多样性和环境因素与潜在授粉者的活动有关。在蒂茹卡森林中,mollicomum 的挥发性成分与微气候变量之间存在显著的相互作用,表明叶片和生殖器官的化学多样性与授粉者的造访相关。此外,这些植被结构之间的化学均匀性也存在明显差异。拉莫斯(Ramos)和莫雷拉(Moreira)的化学遗传指数也显示出与化学多样性的相关性。
From Leaves to Reproductive Organs: Chemodiversity and Chemophenetics of Essential Oils as Important Tools to Evaluate Piper mollicomum Kunth Chemical Ecology Relevance in the Neotropics
Piper mollicomum Kunth (Piperaceae) plays a vital role in the preservation of the Brazilian Atlantic Forest by contributing to the regeneration of deforested areas. Recent scientific investigations have analyzed the chemical constituents and seasonal dynamics of essential oils (EO) from various Piper L. species, highlighting the need to elucidate their chemical–ecological interactions. This study aims to expand the chemical–ecological knowledge of this important taxon in neotropical forests, using P. mollicomum as a model. The methodologies employed include the collection of plant material, EO extraction by hydrodistillation, analysis of EO by gas chromatography–mass spectrometry (GC–MS) and gas chromatography–flame ionization detector (GC–FID), recording the frequency of visits by potential pollinators and microclimatic variables, and by conducting calculations of chemodiversity and chemophenetic indices. Chemical analyses indicated that the diversity of EO and environmental factors are linked to the activities of potential pollinators. In the Tijuca Forest, P. mollicomum revealed significant interactions between its volatile constituents and microclimatic variables, showing that the chemodiversity of the leaves and reproductive organs correlates with pollinator visitation. Additionally, a notable difference in chemical evenness was observed between these vegetative structures. The chemophenetic indices by Ramos and Moreira also revealed correlations with chemical diversity.
