Abstract

This study assessed flower-visitor assemblages, breeding system and pollination of Elaeocarpus floribundus Blume (Elaeocarpaceae) which is widely distributed throughout Asian countries. As soon as flowers opened, an array of flower visitors including members of Diptera, Hymenoptera and Thysanoptera visited flowers for their forage. The members of Diptera (82.6%) were the dominant visitors in comparison to Hymenoptera (10.4%) and Thysanoptera (7.0%). The flower visitor frequency, activity rate and index of visitation rate revealed that Chrysomya sp., Musca domestica and Eristalinus sp. of Diptera acted as potential pollinators. Self-incompatibility index and reproductive efficacy were 0.53 and 0.35 respectively, indicating incomplete self-compatibility. Hand pollination showed significantly higher fruit set in xenogamous pollination (36%) than open pollination (12.82%). A detailed understanding of such flower-visitor interactions will be helpful in the conservation and sustenance of the species as well as biodiversity.

印度橄榄(Elaeocarpus floribundus Blume)的花客多样性和授粉

本研究对广泛分布于亚洲各国的Elaeocarpus floribundus Blume (Elaeocarpus floribundus Blume, Elaeocarpus floribundus Blume)的访花组合、繁殖系统和授粉进行了研究。花朵一开放，包括双翅目、膜翅目和囊翅目在内的一群访花者就会到花朵上觅食。双翅目昆虫占82.6%，膜翅目昆虫占10.4%，翅翅目昆虫占7.0%。访花频率、访花活动率和访花指数表明，双翅目的金蝇(Chrysomya sp.)、家蝇(Musca domestica)和Eristalinus sp.是潜在的传粉媒介。自交不亲和指数和繁殖效率分别为0.53和0.35，表明自交不完全。手传粉的结实率(36%)显著高于开放传粉(12.82%)。详细了解这种花-访花相互作用将有助于物种的保护和维持以及生物多样性。

期刊介绍： Annals of Applied Biology is an international journal sponsored by the Association of Applied Biologists. The journal publishes original research papers on all aspects of applied research on crop production, crop protection and the cropping ecosystem. The journal is published both online and in six printed issues per year. Annals papers must contribute substantially to the advancement of knowledge and may, among others, encompass the scientific disciplines of: Agronomy Agrometeorology Agrienvironmental sciences Applied genomics Applied metabolomics Applied proteomics Biodiversity Biological control Climate change Crop ecology Entomology Genetic manipulation Molecular biology Mycology Nematology Pests Plant pathology Plant breeding & genetics Plant physiology Post harvest biology Soil science Statistics Virology Weed biology Annals also welcomes reviews of interest in these subject areas. Reviews should be critical surveys of the field and offer new insights. All papers are subject to peer review. Papers must usually contribute substantially to the advancement of knowledge in applied biology but short papers discussing techniques or substantiated results, and reviews of current knowledge of interest to applied biologists will be considered for publication. Papers or reviews must not be offered to any other journal for prior or simultaneous publication and normally average seven printed pages.
