ABSTRACT Modern pollen dispersal studies from the phytogeographically and climatically different regions [the Peninsular and extra-Peninsular regions (the Himalaya), the Ganga-Brahmaputra Plain and the coastal regions] of India are summarised and reviewed in the present communication. We have incorporated all the works undertaken on modern pollen dispersal aspects in India. It must be noted that initial studies, though incipient in nature and content, helped in establishing the science of palynology, in the early days, across the varied regions of the vast country. Shorea robusta and Tectona grandis, despite being high pollen producers and dominant components of the deciduous forests, are under-represented in the pollen assemblages; however, Madhuca indica has comparatively good representation. Rhizophora, Aegiceras, Barringtonia, Excoecaria, Sonneratia and Avicennia are the important mangrove taxa recorded from the coastal areas, although their representation is less as compared to the extant vegetation. Mesua, Schima, Elaeocarpus, Ilex and Garcinia are represented well in the pollen spectra from the evergreen forests. Pinus pollen is highly over-represented in the Himalaya. Suggestions for overcoming limitations are also provided, which will improve the accuracy and understanding of modern pollen dispersal studies in the Indian scenario. Recommendations for future research mainly comprise adoption of the established protocols for vegetation surveys. Extended R-value (ERV) models may be applied for estimating the pollen productivity (PPEs) for further use in landscape reconstruction algorithm (LRA) approaches.

印度的现代花粉传播研究：详细的综合和回顾

摘要 本文总结和回顾了印度植物地理和气候不同地区[半岛和半岛外地区（喜马拉雅山）、恒河-布拉马普特拉平原和沿海地区]的现代花粉传播研究。我们已经整合了在印度现代花粉传播方面进行的所有工作。必须指出的是，最初的研究虽然在性质和内容上处于起步阶段，但在早期帮助建立了遍及广大国家不同地区的孢粉学。Shorea Robusta 和 Tectona grandis 尽管是高花粉生产者和落叶林的主要组成部分，但在花粉组合中的代表性不足；然而，Madhuca indica 具有较好的代表性。Rhizophora, Aegiceras, Barringtononia, Excoecaria, Sonneratia 和 Avicennia 是沿海地区记录的重要红树林分类群，尽管与现存植被相比，它们的代表性较少。Mesua、Schima、Elaeocarpus、Ilex 和 Garcinia 在来自常绿森林的花粉光谱中得到很好的代表。松花粉在喜马拉雅山中的比例过高。还提供了克服局限性的建议，这将提高印度情景中现代花粉传播研究的准确性和理解。对未来研究的建议主要包括采用既定的植被调查协议。扩展 R 值 (ERV) 模型可用于估计花粉生产力 (PPE)，以进一步用于景观重建算法 (LRA) 方法。
