| 摘 要： | 为揭示不同穗型品种在寒地特殊气候条件下光合特性和光能利用率的差异,促进水稻高光效品种的选育和合理利用,以不同穗型水稻品种半直立穗型垦稻29、龙稻5号和弯穗型品种垦稻10号、垦稻12为试验材料,在黑龙江省特殊的寒地气候条件下,围绕两种穗型品种的光合特性及利用率进行研究。结果表明:半直立穗型品种在瞬时光合速率、光合速率高值持续期、叶面积和叶源量等方面均优于弯穗型品种。

| Abstract: | In order to prompt the difference between photosynthetic characteristics and sunlight efficiency of different panicle varieties under special climatic conditions in cold region,and provide the theoretical basis for selection and rational utilization of high light efficiency varieties.the photosynthetic characteristics and sunlight efficiency of rice varieties with different panicle types Semi-erect panicle Kendao29,Longdao5 and Curved panicle Kendao10,Kendao12 were studied.The results showed that transient photosynthetic rate,duration of high photosynthetic rate,leaf area and leaf source of semi-erect panicle rice were better than curved panicle rice. |
