裙带菜[Undaria pinnatifida(Harv.)Suringar]属褐藻门褐子纲海带目(Lamina-riales)翅藻科(Alariaceae),是重要的经济海藻之一,在我国舟山群岛、嵊泗列岛、青岛、烟台、大连等地都有其自然分布。裙带菜是一种有明显世代交替的一年生海藻。关于裙带莱的发育形态,前人已有报道。1970—1972年我们在青岛进行人工育苗、养殖试验的过程中,对其发育形态与生态特征作了进一步的观察与描述。在裙带菜的生活周期中,明显地分为配子体(单倍体)和孢子体(双倍体)两个阶段,其形态完全不同。即使在同一发育阶段中,由于所处的环境不同,也会引起形态上的变
Undaria pinnatifida (Harv.) Suringar is a genus of the brown seaweed Lamina-riales Alariaceae. It is one of the important economic seaweeds in China’s Zhoushan Archipelago, Shengsi Archipelago, Qingdao, Yantai Dalian and other places have their natural distribution. Undaria pinnatifida is an annual seaweed that has been clearly alternated from generation to generation. Levin on the development of the form, previously reported. From 1970 to 1972, we conducted further observations and descriptions of the developmental and ecological characteristics of our breeding and breeding experiments in Qingdao. In the wakame life cycle, apparently divided into two stages of gametophyte (haploid) and sporophyte (diploid), its morphology is completely different. Even in the same developmental stage, due to the different environment, will cause morphological changes
