| 中文摘要 |
| 采用开顶式气室对冬小麦、大豆进行不同CO2浓度处理,用紫外可见光光度计、蛋白质分析仪、气相色谱仪、YG-2脂肪提取器和半自动定氮仪等对成熟后冬小麦、大豆籽粒进行成分分析。结果表明,CO2浓度升高对大豆籽粒粗蛋白、粗脂肪含量均有正效应,随CO2浓度升高大豆籽粒不饱和酸含量增加,饱和酸减少。CO2浓度变化对冬小麦籽粒粗蛋白、赖氨酸的影响比较复杂,就蛋白质、赖氨酸2项指标,当大气中CO2浓度增加1倍,对目前冬小麦品种的籽粒品质的影响是负效应。 |
| 英文摘要 |
| Winter wheat and soybean crops were treated with different CO2concentrations in top-open chambers.The matured grains harvested from the crops were analysed for their compositions by using visible ultraviolet spectrometer, protein analyzer, gas chromatograph,YG-2 fat extractor and automanual nitrometer. The results show that an increased CO2 concentration can have a positive effect on the contents of both rough protein and rough fat in soybean grain; and as the CO2 concentration increases, the soybean grain would have an increased level of unsaturated acids and a decreased level of saturated acids. The change in CO2 concentration had a more complicated effect on the levels of rough protein and lysine in winter wheat grain. In terms of both indicators of rough protein and lysine, a doubled concentration of atmospheric CO2 had a negative effect on the quality of grains of the present varieties of winter wheat. |
