Abstract

The current study aims to understand the role of various morphological features of pollen grains in attachment with moth proboscides. To test the hypothesis, moth samples are collected from 11 sites in three districts of Arunachal Pradesh and West Bengal, North East India. Pollen of 18 angiosperm families are isolated from the proboscides of 16 moth species in four families. We selected proboscides for the isolation of pollen because it is the most important organ of moths which interacts with flowers during moth visitation. The isolated pollen is studied for various morphological characters like pollen shape, unit, exine ornamentation, thickness, aperture numbers, and aperture types along with specialized structures i.e., viscin thread and pollenkitt, and analyzed for their attachment on the proboscides. The present study revealed the significant role of pollen shape, unit, exine characters, viscin thread, and pollenkitt in attachment with proboscides. Whereas, the aperture numbers and aperture types are found insignificant in the process of pollen attachment. Studies on the formation of viscin thread and pollenkitt may be established as an important tool to understand the specialized and generalized interactions between moths and angiosperms. The present study will open up a new horizon in pollination ecology.

揭示被子植物花粉形态对飞蛾(鳞翅目)长鼻的附着作用
摘要 目前的研究旨在了解花粉粒的各种形态特征在附着在蛾类探针上的作用。为了验证这一假设,研究人员从印度东北部阿鲁纳恰尔邦和西孟加拉邦三个地区的 11 个地点采集了飞蛾样本。从四个科 16 种蛾类的触角上分离出了 18 个被子植物科的花粉。我们选择长鼻来分离花粉,因为长鼻是飞蛾最重要的器官,在飞蛾拜访花朵时会与花朵产生互动。我们研究了分离出的花粉的各种形态特征,如花粉形状、单位、外皮装饰、厚度、孔数量、孔类型以及特殊结构(即粘纤丝和花粉基特),并分析了它们在长鼻上的附着情况。本研究揭示了花粉形状、单位、外稃特征、黏菌丝和花粉小体在附着在探针上的重要作用。而孔数和孔类型在花粉附着过程中的作用并不明显。对粘胶线和花粉基特形成的研究可能会成为了解蛾类与被子植物之间专门化和普遍化相互作用的重要工具。本研究将为授粉生态学开辟新的视野。
