| 摘 要： | 选用不同耐冷性的2个大白菜材料"534"和"676",利用低温胁迫在植株不出现明显受迫症状的前提下,比较胁迫期和恢复期的叶绿素荧光参数差异。结果表明:低温胁迫使耐冷性弱的"534"Fv/Fm、qP的降幅均比耐冷性强的"676"明显。在胁迫期,"534"、"676"的qN均升高,同时"676"升幅比"534"明显,且2个品种的Yield日变化对低温胁迫的响应差异不明显。经历了3 d恢复后,"676"Fv/Fm、qP的恢复幅度明显高于"534"。但在恢复期2个品种的Yield日变化对低温胁迫后恢复差异不明显。说明"534"在胁迫期受低温的影响较大,"676"在低温胁迫解除后较快得到恢复,这些参数可作为反映品种耐冷能力大小的指标。

| Abstract: | Two different Chinese cabbage varieties(534 and 676)with different cold tolerance were taken as the samples.The difference of diurnal changes of fluorescence parameters which can be used as the trait tolerant to cold were studied in both the period of inhibition and the period of recovery under the condition of low temperature before having obvious damaged symptoms.The results showed that the decreasing extent of Fv/Fm and qP in 534 with weak cold tolerance was significantly bigger than that in 676 which ha... |
