| 摘 要： | 采用改良的桶栽法和排除根系法两种方法测定马铃薯植株在苗期、块茎形成期和块茎膨大期三个阶段根际器官CO2和O2呼吸速率的变化。结果表明:一天之中,马铃薯根际器官的呼吸速率先升高,后降低;O2的呼吸速率和CO2的变化趋势相反;在整个生育期过程中块茎形成期的呼吸速率最大。两种测定方法的根际器官呼吸速率变化趋势一致。 |
| 关 键 词： | 马铃薯 根际器官 呼吸速率 |

| Abstract: | The carbon dioxide and oxygen respiration rate of the rhizosphere organ of potato plant at the seedlings stage, tuber initiation stage and tuber bulking stage was measured by the improved pot method and root exclusion method. The results showed that in a day, the respiratory rate of potato's rhizosphere organ increased firstly in the morning, and then decreased in the afternoon; at the same time, there was a contrary trend for the oxygen respiratory rate of potato rhizosphere organ compared with the carbon dioxide. In the whole growth period, the maximal respiration rate was at the tuber initiation stage. The trend in the change of respiration rate measured by the two methods was consistent. |
| Keywords: | potato rhizosphere organ respiration rate |
