| 摘 要： | 采用实验室内植物块茎培养沉水植物的实验方法,研究了不同质量浓度Pb2+胁迫下龙须眼子菜的生长状况及光合作用参数的变化.结果表明:随着Pb2+浓度的提高,植株高度受到抑制、叶片黄化、植株根部部分变灰腐烂;叶绿素含量显著降低且与铅浓度呈现显著负相关;核酮糖二磷酸羧化酶活性先升高后降低,酶活性与Pb2+浓度呈显著负相关;磷酸烯醇式丙酮酸羧化酶活性变化小;碳酸酐酶活性先降低后上升.

| Abstract: | Using the experiment method of tuber culture in the laboratory,the photosynthesis effects and physiological response of the aquatic macrophyte Potamogeton pectinatus were investigated in Pb2 +with different concentrations. The results showed that the Potamogeton pectinatus growth was inhibited with the increase of the concentration,chlorophyll content reduced significantly and showed negative correlation with Pb2 +concentrations,RuBPc activity first increased and then decreased,and it was negatively correlated with Pb2 +concentrations,PEPc activity changed little,CA activity first decreased and then increased. |
