摘要：

采用盆栽试验研究了燃煤烟气脱硫物施用对苜蓿渗透调节物质和保护酶活性的影响,结果显示:MpT3处理降低MDA含量效果最为明显。在苗期和初花期,MpT1和MpT3处理苜蓿叶片可溶性糖含量和脯氨酸含量升高显著,且以MpT3处理效果最佳;各处理SOD、POD和CAT活性都增加,但MpT3处理比MpT1处理、MpT2处理效果显著。上述结果表明:燃煤烟气脱硫物2.5 g/kg土+改良剂2.5 g/kg土(即MpT3处理)对提高苜蓿的抗逆性效果最佳。

Abstract:

In this paper, pot culture experiment was adopted to study the effect of flue gas desulphurization products on osmotic adjustment solutes and protecting enzymes activities of alfalfa. The results indicate that MpT3 treatment can remarkably reduce MDA content. At seedling and early bloom stages, the content of soluble sugar and proline in alfalfa leaf blades increased remarkably and MpT3 treatment has the best effect. The activities of SOD, POD and CAT increased in all treatments, but MpT3 treatment has better result than MpT1 and MpT2 treatment. The above results indicated that flue gas desulfurization products 2.5 g/kg soil + amendment 2.5 g/kg soil (MpT3) was the best for improving alfalfa stress resistance.

Key words: flue gas desulfurization products, alfalfa, osmotic adjustment solute, protective enzyme, stress resistance
