科學圖說 Introduction
人們印象中的植物通常是綠色、可行光合作用,為自然界中的生產者。但有些植物無葉綠素,沒有行光合作用的能力。牠們以寄生或真菌異營的方式生存,後者如:水晶蘭屬、水玉簪科、黴草科和腐生的蘭花,隱世於腐植土裡靠真菌來獲得養分,在特定季節以讓世人驚豔的樣貌出土。圖片中的「紫水玉簪」是此中的翹楚,每年8-10月開花季節,以夢幻的色彩、特殊的型態,耀眼藏身在密林下。
When we think of plants, the color green, photosynthesis, and producers of the natural world most likely come to mind. However, there are some plants without chlorophyll or the ability to carry out photosynthesis. They are parasitic or mycoheterotrophic. Examples include members of the genus Monotropa and the families Burmanniaceae and Triuridaceae, as well as saprophytic orchids. Preferring the humus layer of soil, such plants rely on fungi for their nutrition and tend not to attract attention, except during specific times of the year. Pictured here is Burmannia itoana Makino. Between August and October, it produces flowers of dazzling color. Otherwise, it remains hidden in dense forest.
