天鹅湖大叶藻种苗补充情况调查
Supplementary investigation of eelgrass seedlings (Zostera marina L.) in Swan lake
摘要
Abstract
In this study, we examined seedlings of the eelgrass Zostera marina L. in a typical lagoon (Swan Lake, Rongcheng, Shandong Province). We conducted an in situ investigation from March to June 2015. During this pe-riod, we measured the eelgrass seedling density, seedling height, leaf sheath height, leaf number, leaf width, and branch number. The results show that while the seeds began to germinate in March, the germination rate was very low, as was the seedling density. In April, many seeds began to germinate, and the seedling density increased rap-idly and reached a peak (481.77 ± 303.42 shoots·m−2). The seed germination ended in May, and the seedling density decreased gradually. The seedlings began to branch new shoots in May, and these seedling shoots continued to grow and produced sexual shoots in June. At this time, seedling germination had ended, and the seedlings entered the sexual reproduction stage.关键词
