| 摘 要： | 分别研究了实验室条件卜紫外灯照射及不同季节中目光照射对噬藻体PP活性的影响。结果表明紫外光(UV-A和UV-B)对噬藻体PP有较强的致失活作用，并且其致失活作用强弱与波长有关。日光的作用下，夏季时噬藻体PP的日失活率为88．60％，冬季时为58．86％。同时发现不同季节中，尽管在某些时段的目光强度相似，但噬藻体PP失活率的差别却较大，这一现象可能是由于光质不同引起的。上述结果有助于解释淡水环境中噬藻体种群大小的季节性波动。

| Abstract: | The results of UV and sunlight on the activity of freshwater cyanophage PP are presented in this paper. Both UV-A and UV-B resulted in significant inactivity of cyanophage, though the effect was different. The outdoor performance showed that the day inactivity rates of cyanophage by sunlight in summer and winter were 88.60% and 58.86%, respectively. It was also found that in spite of the similar sunlight intensity at some time interval in two seasons,the inactivity rate was of a considerable diversity. Different sunlight constituent might be responsible for the diversity. The results were useful for explaining the seasonal change in cyanophage population in freshwater. |
