    摘要:
    蘭科是植物王國中最多樣化的分類群之一，它的大多數(shù)成員都是非常有價值的草藥。蘭花在其整個生命周期中與特定的真菌有著獨特的菌根共生關(guān)系，為其提供碳水化合物和營養(yǎng)物質(zhì)。藥用植物天麻的大規(guī)模栽培是應(yīng)用菌根共生技術(shù)的成功范例。本文以藥用蘭科植物天麻和鐵皮石斛為例，闡述了蘭花菌根的特點以及菌根對寄主植物生長和健康的益處(如提高宿主植物對生物脅迫和非生物脅迫的抵抗力，提高次生代謝物積累)，討論了今后菌根技術(shù)在蘭科藥用植物栽培中的應(yīng)用面臨的挑戰(zhàn)，旨在為藥用蘭花菌根培養(yǎng)技術(shù)的研究提供理論指導(dǎo)。

    Abstract:
    The family Orchidaceae is of the most diverse taxon in the plant kingdom, and most of its members are highly valuable herbal medicines. Orchids have a unique mycorrhizal symbiotic relationship with specific fungi for carbohydrate and nutrient supplies in their whole lifecycle. The large-scale cultivation of the medicinal plant Gastodia elata is a successful example of using mycorrhizal symbiotic technology. In this review, we adopted G. elata and Dendrobium officinale as examples to describe the characteristics of orchid mycorrhiza and mycorrhizal benefits for host plants’ growth and health (e.g. biotic and abiotic stress and secondary metabolite accumulation). The challenges in applying mycorrhizal technology to the cultivation of orchid medicinal plants in the future were also discussed. This review aims to serve as a theoretical guide for the cultivation of mycorrhizal technology in medicinal orchid plants.
