研究了亚硒酸钠（Na2SeO3）对提高麝香三浦切花瓶插寿命的作用。结果表明，Na2SeO3显著提高了百合切花花瓣的超氧化物歧化酶（SOD）、过氧化物酶（POD）、过氧化氢酶（CAT）、抗坏血酸过氧化物酶（APX）、谷胱甘肽还原酶（GR）、脱氢抗坏血酸还原酶（达尔）和单脱氢抗坏血酸还原酶（MDHAR）的活性，提高了花瓣的相对含水量（RWC）以及可溶性糖、脯氨酸和可溶性蛋白的含量，与对照相比。与对照组相比，Na2SeO3显著降低了丙二醛（MDA）和过氧化氢（H2O2）的生成。Na_2SeO_3处理显著提高了百合的瓶插寿命。麝香切花与对照相比。说明亚硒酸钠通过调节L.麝香切花
In this paper, we studied the role of sodium selenite (Na2SeO3) in improving cut flower's vase life of Miura longiflorum. Experimental findings displayed that Na2SeO3 remarkably enhanced the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), dehydroascorbate reductase (DHAR) and monodehydroascorbate reductase (MDHAR), improved relative water content (RWC) and the levels of soluble sugar, proline and soluble protein in cut flower's petals of Lilium longiflorum, compared with control. Meanwhile, Na2SeO3 remarkably decreased the production of malondialdehyde (MDA) and hydrogen peroxide (H2O2), compared with control. Furthermore, Na2SeO3 remarkably improved the vase life of L. longiflorum cut flower, compared with control. These findings suggested that Na2SeO3 improved the vase life by regulating the antioxidant system and osmotic adjustment ability of L. longiflorum cut flower.
