石蒜属植物功能性状的系统发育信号及黄花石蒜对环境变化的响应研究

Phylogenetic Signals of Functional Traits of Lycoris L. and Response of Lycoris aurea to Environmental Changes

石蒜属(Lycoris)为多年生草本植物,该属植物全世界约20种,其中中国的种类最多,约15种,主要在我国南方的阴湿山坡地区有分布。其全草含有的石蒜碱可作为治疗小儿麻痹症的重要药物。由于石蒜属植物独特的生理习性以及花形,常被用作林下地被花卉和理想的切花材料。然而,在以往的研究多关注于石蒜属植物的经济和药用价值,对于植物本身的功能性状系统发育研究及其对环境变化的响应尚缺少较为系统的评估。因此,本文主要介绍石蒜属植物功能性状及其对环境变化的响应,将从石蒜属植物功能性状、系统发育信号和全国分布3方面来阐述中国石蒜属植物功能性状的系统发育信号及其对环境变化的影响,在今后的研究中将着重探讨以下几个问题:1) 不同种石蒜植物受不同进化历史影响是否也会表现出系统发育信号呢?2) 植物功能性状的发生和发展是否受到环境因素的显著影响?3) 黄花石蒜受环境影响在空间上的生态策略。

Lycoris is a perennial herbaceous plant. There are about 20 species of Lycoris in the world, among which China has the most species, about 15 species, which are mainly distributed in the humid mountain slopes in southern China. The lycorine contained in the whole grass can be used as an important drug in the treatment of polio. Because of its unique physiological habits and flower shape, Lycoris is often used as understory groundcover flowers and ideal cut flower materials. However, most of the previous studies focused on the economic and medicinal value of Lycoris, and the phylogenetic studies on functional traits of Lycoris and their response to environmental changes were not systematically evaluated. Therefore, this paper mainly introduces the functional traits of Lycoris plants and their responses to environmental changes. The phylogenetic signals of functional traits of Lycoris plants in China and their effects on environmental changes will be elaborated from the three aspects of functional traits, phylogenetic signals and national distribution of Lycoris plants. Future studies will focus on the following issues: 1) Do different species of Lycoris also show phylogenetic signals under the influence of different evolutionary histories? 2) Are the occurrence and development of plant functional traits significantly affected by environmental factors? 3) The spatial ecological strategies of Lycoris aurea affected by the environment.
