| 摘 要： | 随着条斑紫菜栽培事业和科学实验的进展,人们已对紫菜丝状体生长发育的规律有了较详细的了解,从而能够有效地促进紫菜丝状体大量形成和放散壳孢子及壳孢子的附着。然而对于紫菜叶状体形成、放散单孢子及其附着,除右田清治曾对单孢子的附着光强进行过研究外,尚未见到其他的报道。本实验就条斑紫菜单孢子的形成、放散和附着同光线强度的关系做了进一步实验观察,现将实验结果报告如下。

THE INFLUENCE OF THE LIGHT INTENSITY ON THE FORMATION, DISCHARGE AND ADHERENCE OF MONOSPORES |
| |
| Abstract: | 1. The influence of light intensity on the formation of monospores was obvious, but almost no influence on the amount of monospores discharged was observed if thalli were treated below 11,000 lux during the period of discharging. 2. The influence of light intensity was also obvious on the number of monospore adhered, the ratio of the number of monospore adhered to that discharged increased with the increase of light intensity. The optimum light intensity for monospores adherence ranged from 15,000-26,000 luxes. |
