依營養特徵編列暖季草坪植物檢索表及區別特徵圖鑑之研究

The Establishment of a Key and Illustrations of Warmseason Turfgrasses by Vegetative Characteristics

草坪植物（Turfgrass）為公園綠地常見的地被植物之一。本研究將台灣常見之暖季草種包括百慕達草（Bermudagrass）、日本芝草（Japanese Lawngrass）、馬尼拉草（Manilagrass）、高麗芝（Mascarenegrass）、聖奧古斯汀草（St. Augustinegrass）、鑲邊聖奧古斯汀草（Variegated St. Augustinegrass）、假儉草（Centipedegrass）、大葉百喜草（Bahiagrass-A44）、小葉百喜草（Bahiagrass-A33）、地毯草（Tropical Carpetgrass）、類地毯草（Common Carpetgrass）、竹節草（Lovegrass）、兩耳草（Sourgrass）、雙穗雀稗（Knotgrass）、克育草（Kikuyugrass）、垂愛草（戀風草，Weeping Lovegrass）等16種，利用營養器官如幼葉走向（葉褶，vernation）、葉身（blade）、葉鞘（sheath）、葉領（collar）、葉舌（ligule）等特性，建立草種簡易分類表，並依此為基礎研擬出檢索表，此外並用相機配合放大鏡、解剖顯微鏡依其主要辨別部份拍攝其重要的鑑別特徵，以建立台灣暖季草坪植物的圖鑑，供相關人員能簡易、精確地鑑別草種。

Turfgrass is one of the commonly used groundcovers in parks. Sixteen warmseason turfgrass species, including Bermudagrass, Japanese Lawngrass, Manilagrass, Mascarene grass, St. Augustine grass, Variegated St. Augustinegrass, Centipedegrass, Bahiagrass(A44), Bahiagrass(A33), Tropical Carpetgrass, Common Carpetgrass, Lovegrass, Sourgrass, Knotgrass, Kikuyugrass and Weeping Lovegrass were collected. The characteristics of vegetative organs, such as vemation, blade, sheath, collar and ligule...etc were used to establish a simple key for turfgrass identification. Besides this, a camera, magnifying glass and microscope were used for taking pictures to establish a detailed illustration for warm season turfgrasses in Taiwan.
