Changes of Photosynthetic Behaviors in Kappaphycus alvarezii Infected by Epiphyte
Epiphytic filamentous algae (EFA) were noted as a serious problem to reduce the production and quality of K. Alvarezii. The morphological studies revealed that the main epiphyte on K. Alvarezii was Neosiphonia savatieri in China. Though the harmful e.ects of EFA on the production of K. Alvarezii have been reported, the detailed mechanism of the N. Savatieri in limiting the production of K. Alvarezii has not been studied yet. The present paper studied the e.ects of N. Savatieri infection on photosynthetic behaviors in K. Alvarezii by detecting chlorophyll fluorescence transient in vivo. The results revealed that damage of oxygenevolving complex (OEC), decrease of active reaction centers (RCs), and the plastoquinone (PQ) pool as well as significant reduction in the performance indexes (PI) of PSII were caused by the infection of N. Savatieri. The influence of N. Savatieri on photosynthetic activity of K. Alvarezii should be one of the important reasons to reduce the production of K. Alvarezii infected by N. Savatieri.
