摘要
比较了‘富士王’、‘美国8号’、‘夏红’、‘弘前富士’4个苹果品种的光合特性,以期为西藏苹果品种的筛选提供参考。结果表明:‘夏红’、‘弘前富士’的光补偿点(LCP)较低,分别为26.43和30.06μmol.m-2.s-1;CO2补偿点(CCP)以‘弘前富士’最低,为53.07μmol.mol-1。‘夏红’的表观量子效率(AQY)最高,为0.0411;‘富士王’最低,为0.0377;‘弘前富士’和‘夏红’的羧化效率(CE)最高,分别为0.0747、0.0750,说明对低浓度CO2的利用效率较强;‘夏红’的叶绿素总含量最高,而叶绿素a/b以‘美国8号’最高。
To provide the basis for cultivar screening in Tibet,photosynthetic characteristics of four apple cultivars ‘Fushiwang’,‘America No.8’,‘Xiahong’,‘Hirosaki’were studied.The results showed that ‘Xiahong’and ‘Hirosaki’had the higher light compensation point（LCP）,which were 26.43and 30.06 μ mol·m-2·s-1 respectively.‘Hirosaki’had the lowest CO2 compensation point（CCP=53.07 μ mol·mol-1）.The apparent quantum yield（AQY） ranged from 0.0377（‘Fushiwang’） to 0.0411（‘Xiahong’）.‘Hirosaki’and ‘Xiahong’had the higher carboxylation efficiency（CE）,which were 0.0747and 0.0750respectively.Among four apple cultivars,chlorophyll content of ‘Xiahong’were highest and chlorophyll a/b of ‘America No.8’were higher.
