| TRANSPLANTATION AND CULTIVATION OF TWO SPECICS OF LAMINARIA |
|
|
| Abstract: |
| In the spring of 1981, two species of Laminaria, i. e. L. longicruris and L. sp., have been transplanted from the coast of Canada to Qingdao. The experimental results showed that L. longicruris, is characterized by firstly the slower growth rate of the frond and more rapid growth rate of the stipe at 1-12 ℃, resulting in a shorter frond and a longer stipe and secondly a less water content as compared with our new variety, №. 860 (L. japonica), and that L, sp., is characterized by firstly the slower growth rate of the frond and secondly a less water content in different growth and development periods of sporophyte. |
