摘要/Abstract

摘要：

荒漠植物适应长期缺水条件形成了从空气吸水并在体表滞留及向体内运输的高度进化的结构特征，其叶片表面附属结构如表皮毛等在收集、储存及运输凝结水方面具有重要的生物学意义。本文基于目前相关研究进展，简要概述了凝结水对荒漠植物的生物学效应及生态效应，阐述了叶片表面润湿性与其集水能力相关理论，基于此重点阐述荒漠植物叶表特殊结构（表皮毛）在凝结水形成、运输、吸收过程中的重要作用，并总结了植物体表滞留及吸收凝结水的相关研究方法，为深入理解基于表皮毛结构特征驱动的荒漠植物收集凝结水的策略以及干旱荒漠植物的抗逆机制提供理论依据。

Abstract:

Desert plants have developed highly evolved water preservation and transportation systems for collecting and storing water through air under chronic water scarcity, the accessory structures such as trichomes on the leaf surface have important biological significance in collection, storage and transportation of the condensed water. Based on the current research progress, this review briefly summarizes the biological and ecological effects of condensate on desert plants, and expounds the theories related to leaf surface wettability and water collection capacity. Based on this, the important role of special structure of desert plants’ leaf surface (trichome) in the formation, transport and absorption of condensate is mainly discussed. The research methods of surface retention and absorption of condensate water were summarized, which may provide guidance for further study on trichome function and is helpful to understand the mechanism of condensate collection by desert plants driven by its structural characteristics in arid areas of China.

Key words: desert plant, condensed water, leaf surface wettability, trichome, ecological effect
