| 为揭示自然界不同基因型大豆冠层温度是否存在分异,应用红外测温仪对5个大豆品种植株的冠层温度进行了长期观测,并同步测定了大豆主茎功能叶片的绿叶百分率、可溶性蛋白质含量、超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性、丙二醛(MDA)含量。结果表明,自然界存在冠层温度偏低的低温大豆种质即冷型大豆(如汾豆55、冀NF58)和冠层温度偏高的高温大豆种质即暖型大豆(如东大2号、渭豆20)。在整个籽粒灌浆期,冷型大豆绿叶百分率、可溶性蛋白质含量、超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性均比暖型大豆优越,丙二醛(MDA)含量随生育期的推移积累速度也较暖型大豆明显慢。由此认为不同基因型大豆冠层温度存在分异,且温度型与功能叶片衰老特性的优劣有着紧密的联系。 |

| In order to find out whether difference exists in canopy temperature of soybean of different genotypes,infrared radiation thermometer was used to determine the soybeans canopy temperatures of five varieties for a long time,at the same time,determination was also made of percentage of green leaf,soluble protein content,SOD activity,CAT activity and MDA content of the functional leaves of soybean caulis in the periods of duration.The results showed that there were soybean germplasm of low canopy temperature and soybean germplasm of high canopy temperature,the cold soybean Fendou 55 and Ji NF 58,the warm soybean Dongda 2 and Weidou 20,for examples.During the whole seed filling-time,the percentage of green leaf,soluble protein content,SOD activity,CAT activity of cold soybean were superior to warm soybeans and the accumulation of MDA content was obvious slower with process of period of duration.According to these it is thought that difference phenomenon exists in canopy temperature of different genotype soybeans and the relation between temperature type and quality of senescence characters of leaf function was close,which could offer academic base for high yielding and dependable cropping of soybean. |
