摘　　要：以淡竹为研究对象,分别对不同健康状态淡竹叶片进行光合速率、SPAD值、叶片干重3项指标变化情况进行测量。研究结果表明,煤污病导致染病淡竹净光合速率下降,SPAD值升高,叶片干重下降。We measured the changes of photosynthetic rate,SPAD value and leaf dry weight of the leaves of Phyllostachys glauca in different health conditions.The results showed that the net photosynthetic rate decreased,the SPAD value increased and the dry weight of the leaves decreased due to coal stain.

关 键 词：淡竹 煤污病 光合速率 叶片干重
