摘要对新西兰南岛Avon - Heathcote河口（43°32′S, 172°44′E）和其他河口环境的Ulva形态变化进行了为期3年的野外和实验室研究。结果表明,标本在某个阶段的增长符合诊断石莼以,美国lacluca var. rigida,美国以var. lacinulata, latissima和美国laingii组成一个物种和最好的被称为美国以6。在蓝杉形态上的变化可能与其生境盐度较低有关。
Abstract Morphological variation of Ulva from the Avon‐Heathcote Estuary (43° 32’ S, 172° 44’ E) and other estuarine environments in the South Island of New Zealand has been followed in the field and in the laboratory over a 3‐y period. Results indicate that specimens which at some stages of growth fit diagnosis for Ulva lactuca, U. lacluca var. rigida, U. lactuca var. lacinulata, U. latissima and U. laingii comprise a single species and are best referred to U. lactuca. In the U. laingii form, the variation in morphology could be related to the lower salinity of its habitat.
