摘要

测定了8种陆生蓝绿藻的叶绿素稳定指数,这些蓝绿藻分别采集于其自然栖息地树皮、土壤和屋顶以及培养物中。与培养的藻类相比,来自自然栖息地的藻类显示出更高的叶绿素稳定性。在天然藻类中,生活在不利生境的藻类叶绿素稳定性较高。对Murty和Majumder(1962)测定叶绿素稳定指数的方法作了一些修改。在这里,加热后的样品相对于未加热的样品的Chl α量的总损失百分比被认为是叶绿素稳定性指数。

Effect of temperature on chlorophyll stability of some subaerial blue-green algae.

Chlorophyll stability index of eight subaerial blue-green algal species, collected from their natural habitats, i.e., bark of trees, soil and roof-tops and from cultures, has been determined. The algae from natural habitats showed greater chlorophyll stability compared to those algae from cultures. Among the natural algae, high chlorophyll stability was observed in the algae inhabiting adverse habitats. A slight modification in the method of Murty and Majumder (1962) for determination of chlorophyll stability index has been made. Here the total percentage loss in the amount of Chl alpha of heated sample in relation to its unheated sample has been considered as chlorophyll stability index.
