Chlorophyll fluorescence characteristics of several plant species in Quanzhou Bay estuarine wetland
摘要
Abstract
Aegiceras corniculatum, Kandelia candel and Avicennia marina are the dominant plant species of Quanzhou Bay estuarine wetland. The characteristics of chlorophyll fluorescence of plants in the wetland from different locations (upstream, midstream and downstream) at different times was studied. Initial fluorescence in Aegiceras corniculatum (0.187) was the greatest at noon, which suggested that Aegiceras corniculatum undergo large environment stress at this time. At downstream, the chlorophyll initial fluorescence of Aegiceras corniculatum in the morning (0.129) was significantly less than that in the afternoon (0.173), and that of K.candel in the morning (0.142) was also significantly less than that in the afternoon (0.171). The maximum quantum yield of Aegiceras corniculatum and K.candel, 0.795 and 0.799 respectively, was significantly higher than that of each plant species in the afternoon. It suggested that the environmental stress on the plants in the morning was less than that in the afternoon at downstream. The curves of chlorophyll fluorescence in response to photosynthetically active radiation showed that the photosynthetic potential and the capture light energy efficiency of the Aegiceras corniculatum in the morning were lower than those in the afternoon. At downstream, the photosynthetic potential and the capture light energy efficiency of Aegiceras corniculatum in the morning was the highest. Mature K.candel in the afternoon was provided with the highest the photosynthetic potential and the capture light energy efficiency. The photosynthetic potential and the capture light energy efficiency of the 5-year-old K.candel in the morning was the least at upstream. Mature Aegiceras corniculatum, K.candel and Avicennia marina were provided with good adaptability.关键词
