摘　　要：为探明超级稻与普通杂交稻、常规稻不同水稻品种的光合特性及其差异。江西省农业气象试验站于2008—2009年对‘金优458’、‘金优463’、‘两优287’、‘株两优211’和‘禾盛10’等早稻品种,以及‘淦鑫688’、‘岳优712’、‘两优培九’、‘欣荣优254’和‘赣晚籼37’等晚稻品种,在水稻生长的各生育期,利用LI-6400光合仪对试验水稻进行了叶片光合观测,并分别对光合观测数据进行了比较分析。结果表明：早稻的光补偿点为25.7-35.7μmol/（m^2·s）,晚稻的光补偿点为29.5-35.3μmol/（m^2·s）;早稻的表观量子效率为0.0401-0.0481,晚稻的表观量子效率为0.0387-0.0503;早稻的暗呼吸速率为1.0879-1.7975μmol/（m^2·s）,晚稻的暗呼吸速率为1.2778-1.6051μmol/（m^2·s）;早稻的CO2补偿点为66.6-75.4μmol/（m^2·s）,晚稻的CO2补偿点为75.6-87.6μmol/（m^2·s）;早稻的表观羧化效率为0.0594-0.1089,晚稻的表观羧化效率为0.0547-0.0764。进一步统计分析得出,同期栽培的不同试验水稻品种,叶片的暗呼吸速率、光补偿点、表观量子效率、CO2补偿点和表观羧化效率等光合参数值均无显著差异。Photosynthetic characteristics from different rice varieties such as‘Jinyou458＇,‘Jinyou463＇,‘Liangyou287＇, ‘Zhuliangyou211＇, ‘Hesheng10＇ and ‘Ganxin688＇, ‘Yueyou712＇, ‘Liangyoupeijiu＇,‘Xinrongyou254＇,‘Ganwanxian37＇were measured. The results indicated that the light compensation pointwas 25.7-35.7 μmol/（m^2·s） of early rice, 29.5-35.3 μmol/（m^2·s） of late rice; the apparent quantum yield was0.0401-0.0481 of early rice, 0.0387-0.0503 of late rice; the dark respiration was 1.0879-1.7975 μmol/（m^2·s）of early rice, 1.2778-1.6051 μmol/（m^2·s） of late rice; the CO2 compensation point was 66.6-75.4 μmol/（m^2·s）of early rice, 75.6-87.6 μmol/（m^2·s） of late rice; the carboxylation efficiency was 0.0594-0.1089 of early rice,0.0547- 0.0764 of late rice; dark respiration, light compensation point, apparent quantum yield, CO2 compensation point and carboxylation efficiency of single leaf from different rice varieties had no significantdifference.
