| 中文摘要: |
| 测定了CO2浓度倍增对水稻植株和褐飞虱蜜露中游离氨基酸浓度的影响。结果表明，CO2浓度对稻茎中游离氨基酸的总量没有影响，不同CO2浓度处理间游离氨基酸浓度的大小排序基本相同；CO2浓度倍增显著增加稻茎伤流液和褐飞虱蜜露中的游离氨基酸总量，游离氨基酸浓度在CO2浓度处理间存在明显差异。因此，CO2浓度倍增对稻茎中游离氨基酸的影响甚微，对褐飞虱取食后稻茎伤流液和褐飞虱蜜露中游离氨基酸的含量和组成存在明显影响，从而不利于褐飞虱种群的增长。 |
| 英文摘要: |
| Effects of doubled CO2 concentration on content of free amino acids in rice plant and honeydew of the brown planthopper were measured in this study. The results showed that CO2 concentration did not affect the total content of free amino acids in rice stem, and the free amino acids ranked in terms of contents at almost the same order between different treatments. In rice stem sap and planthopper honeydew, the total content of free amino acids significantly increased at doubled CO2 concentration, and the rank of free amino acids according to concentration differed significantly between different treatments. These results suggest that doubled CO2 concentration has little effect on the free amino acids in rice stem, but obviously influence the content and composition of free amino acids in rice stem sap and planthopper honeydew. |
