【摘要】 实验研究了偏振与非偏振激光对亚心形扁藻的促长作用、叶绿素含最以及色素粗提物吸收光谱等生物学效应的影响。采用488 nm,70 mW输出功率的氩激光,辐照亚心形扁藻,隔天取样进行细胞计数,培养至第6天提取叶绿素,测量叶绿素含量并扫描叶绿素的吸收光谱。实验结果表明,偏振激光与非偏振激光辐照对藻细胞密度、生长速率的促长作用区别不显著;偏振性与否对叶绿素含量的累积没有明显的区别;激光偏振性对色素粗提物的吸收光谱没有影响。激光偏振性与否均可对亚心形扁藻的生物效应产生有效的作用,激光偏振性与激光生物效应关系的研究有待于进一步深入。更多还原

【Abstract】 In this paper, the purpose is to study the biological effects of platymonas subcordiformis irradiated by polarization and non-polarized laser, such as promoting, pigment chlorophyll content and absorption spectra of pigment extracts. The platymonas subcordiformis were irradiated by the argon laser at 488 nm, 70 mW output power. The number of algae cells were counted by sampling in two days interval, and after culturing six days, the chlorophyll was extracted and its content to be detected and the absorption spectrum of chlorophyll to be scanning. The result showed that, for the platymonas subcordiformis irradiated by polarization and non-polarized laser, the effect of growth promoting was not clear distinction, the cumulative of chlorophyll content was not different, and the absorption spectrum of pigment extracts did not vary also. On our reseach conditions, whether the laser on polarization or not are all the effective role of biological effects of platymonas subcordiformis. The relation of laser polarization and laser biological effects is to be further studied.更多还原
