中文摘要	以本地品种小红毛、常规品种陇谷11号、晋谷29号和杂交品种张杂谷5号、华大3号为供试材料,在宁夏同心县旱作田比较孕穗期和灌浆中期不同谷子品种叶片光强-光合响应曲线及光合参数的变化特点。结果表明:在孕穗期,不同谷子品种的表观量子效率在0.044~ 0.079 mumol·m~(-2)·s~(-1)之间,光补偿点的变化范围在14.11~ 50.59 mumol·m~(-2)·s~(-1)之间;最大光合速率的变化范围为38.53~ 50.01 mumol·m~(-2)·s~(-1),暗呼吸速率变化范围为2.16 ~ 5.28 mumol·m~(-2)·s~(-1)。本地品种小红毛在孕穗期的表观量子效率高( 0.079 mumol·m~(-2)·s~(-1) ) ,利用低光强的能力较强,而常规品种和杂交品种的最大光合速率较高(陇谷11号和晋谷29号分别为38.53、47.53 mumol·m~(-2)·s~(-1)、张杂谷5号和华大3号分别为44.06、50.01 mumol·m~(-2)·s~(-1) ) ,利用强光的能力强,且杂交品种大于常规品种。常规品种和杂交品种的光合能力强,可为谷子获得高产奠定基础。
英文摘要	In order to better understand the response of leaf photosynthesis of various millet varieties to light intensity,we used local millet varieties ( Xiaohongmao) ,conventional variety ( Longgu 11,Jingu 29) ,and hybrid varieties ( Zhangza 5,Huada 3) as experimental crops. The photosynthetic response curves and photosynthetic parameters were studied in booting and filling stages. It is found that the maximum photosynthetic rate,apparent quantum efficience,dark respiration rate,and light compensation point in booting stage were higher than that in filling stage. At the booting stage,the apparent quantum efficiency of different millet varieties is between 0.044 and 0.079 mumol·m~(-2)·s~(-1),and the light compensation point varies from 14.11 to 50.59 mumol·m~(-2)·s~(-1) . The maximum photosynthetic rate ranged from 38.53 to 50.01 mumol·m~(-2)·s~(-1),and the dark respiration rate ranged from 2.16 to 5. 28 mumol · m-2 · s-1,respectively. Compared with other varieties the apparent quantum yield of Xiaohongmao ( local variety) was higher ( 0.079 mumol·m~(-2)·s~(-1) ) ,and it had a great ability to use low light intensity. Nevertheless,The maximum photosynthesis of conventional varieties and hybrid varieties was higher than local variety ( Longgu 11,and Jingu 29 were 38.53 and 47.53 mumol·m~(-2)·s~(-1),Zhangza 5 and Huada 3 were 44.06 and 50.01 mumol·m~(-2)·s~(-1),respectively) . Conventional varieties and hybrid varieties had a great ability to use highlight intensity,and hybrid variety had a stronger ability to use highlight intensity than conventional variety. Conventional varieties and hybrid varieties had a higher photosynthetic capacity,which established the foundation of high yield.
