背景:藤本植物和藤本植物的攀爬策略影响攀登者的竞争能力和生存。这项研究的目的是研究每种植物的攀爬策略并观察其起源器官。
结果:结果显示,所有台湾登山者约为555种,占本地植物区系的11%。在555名登山者中,缠绕茎型是最常见的,共有255种(46%),其余的攀爬方法占300种。大约21种攀爬方法,包括九种组合类型,被展出,其中最常见的类型是缠绕茎,其次是简单的争夺和缠绕卷须。豆科和夹竹桃科的大多数物种都是右旋缠绕的茎,不包括网纹紫藤和黄连,在左旋。Fissistigma属的可理解分支,Ventilago属,和Dalbergiabenthamii,起源于二阶或修饰的茎。在简单加扰类型中,一些登山者被刺和刺覆盖以附着宿主,其他人紧紧抓住支撑物或在地面上爬行,没有猜测。钩虫属的钩子或石墨来自分支,和一对弯曲的钩子或Artabotryshexapetalus的脊柱起源于花序,紧紧地附着在寄主上。派珀属使用粘性根来攀爬寄主。在天花粉属中,只有天花粉homophylla表现出缠绕修饰的芽和粘附根的组合。Gentianales包括四个具有七个攀爬机制的家庭,而Fabales只包括豆科,其中介绍了六种攀爬方法。
结论:缠绕的卷须在台湾登山者中有9个起源器官,这些关于起源器官的观点可能适用于趋同进化的研究。本文提供的数据提供了登山者习惯类型和起源结构的重要基本信息,可用于术语标准化,以改善实地调查。这些术语将有助于建立登山者的习惯,因为它们通常是特定于分类单元的,并且两种登山者习惯的结合可能是分类学价值的特征。
BACKGROUND: The climbing strategies of lianas and herbaceous vines influence climber competition abilities and survival. The aim of this study was to investigate the climbing strategies of each plant species and observe their organs of origin.
RESULTS: The results showed that all Taiwan climbers were approximately 555 species, accounting for 11% of the native flora. Among the 555 climbers, the twining stem type was the most common, with a total of 255 species (46%), the remaining climbing methods accounted for 300 species. Approximately twenty one climbing methods, including nine combination types, were exhibited, of which the most common type was the twining stem, followed by simple scrambling and twining tendrils. Most species of Fabaceae and Apocynaceae were twining stems in dextrorse, excluding Wisteriopsis reticulata and Alyxia taiwanensis, which were in sinistrorse. The prehensile branch of Fissistigma genus, Ventilago genus, and Dalbergia benthamii, originated from second-order or modified stems. In the simple scrambling type, some climbers were covered spines and prickles to attach the host, and the others were clinging to the supports or creeping on the ground without speculation. The
hooks or grapnels of the genus Uncaria are derived from the branches, and a pair of curved
hooks or a spine of Artabotrys hexapetalus are originated from the inflorescence to tightly attach to a host. The Piper genus use adhesive roots to climb their hosts. Among the genus Trichosanthes, only Trichosanthes homophylla exhibits a combination of twining modified shoots and adhesive roots. Gentianales includes four families with seven climbing mechanisms, while Fabales includes only Fabaceae, which presents six climbing methods.
CONCLUSIONS: The twining tendrils had nine organs of origin in Taiwan climber, that these opinions of originated organs might be available to the studies of convergent evolution. The data presented herein provide crucial basic information of the climber habits types and origin structures, which are available for terms standardization to improve field investigation. The terminologies would aid in the establishment of climber habits as commonly taxon-specific and the combination of two climber habits could be a characteristic of taxonomic value.
