摘要
为寻找对SO2伤害敏感的叶片吸收光谱植被指数,通过田间熏气对水稻叶片吸收光谱与部分生理生化指标的相关性进行研究。结果表明,所测的生理生化指标中,只有POD酶与差值比值组合吸收光谱植被指数在三个品种水稻之间都呈极显著相关,其中BEACI、REACI与POD酶显著正相关,YEACI与POD酶极显著负相关。进一步分析可知,过氧化物酶随着SO2浓度的增加而增加。差值比值组合吸收光谱植被指数BEACI、REACI和YEACI具有通过预测水稻叶片POD酶活性变化而诊断SO2毒害程度的潜力。
In order to find the absorption spectra vegetation indices of rice leaves sensitive to sulfur dioxide toxicity, the rice leaves absorption spectra and some relevant physiological and biochemical indices were studied with field fumigation method. The results showed that only the combination of peroxidase （POD）enzyme and the ratio of the difference absorption spectral vegetation index in the three rice varieties were significant correlation. And POD enzyme was significant positive correlation with BEACI and REACI, significant negative correlation with YEACI. Further analysis showed that the concentration of peroxidase increasing with the SO2. Ratio of the difference absorption spectral vegetation indices BEACI, REACI and YEACI were potentiaho diagnose the damage caused by SO2 by the changes in POD activity.
