Chlorophyll Fluorescence Characteristics of Five Dwarf Bamboos
摘要
Abstract
The chlorophyll fluorescence parameters of five introduced dwarf bamboos were measured by IMAGING - PAM chlorophyll fluorometer. The results showed that the differences in photochemical quenching coefficient (qP) and quantum yield of photosystem Ⅱ electron transport (Φ PS Ⅱ ) of Pleioblastus argenteoslri atus, P. Glabraf. Albo - striata, P. Fortunei, P. Kongosanensis f. Aureo - striaus, and P. Auricoma were not extremely significant. Apparent photosynthetic electron transport rate ( ETR) and non - photochemical quenching coefficient (qN) of Pleioblastus auricoma were significantly higher than those of P. Argenteostriatus and P. Kongosanensisf. Aureo - striaus (P < 0. 05 ). The maximal photochemical efficiency of photosystem Ⅱ ( Fx/Fm ) of P. Argenteostriatus was significantly lower than that of the other four dwarf bamboos ( P <0.05 ). The adaptabilities to the full illumination environment and the capabilities of defensing photoinhibition of P. Ar genteostriatus were the lowest of the five dwarf bamboos. It' s light saturation point was 800 μmol/(m ? S) with its highest ETR (60 μmol/( m2 ? S) ). The light utilization efficiency and capability of defensing photoin hibition of P. Auricoma were the highest of the five dwarf bamboos. It' s light saturation point was 1 300 μmol/(m2 ? S) with its highest ETR (110 μmol/(m2 ? S)).关键词
