抗坏血酸过氧化物 meaning in Chinese
apx
Examples
- With the increase of exposure time , the antioxidative ability of spirodela polyhiza dereased , sod and ap activities were induced , and asa content of treated plants were always lower than those of control plants , but the proline ( pro ) contents in treated plants increased . these factors would break the balance of the metabolism of ros and the active oxygen accumulation in leafy thallus of spirodela polyhiza could be the result , the membrane lipid peroxidation was accelerated ( mda content increased ) , ultra - microstructure of chloroplast was damaged , photosynthetic capacity dereased , biomass ( dry weight ) reduced
实验研究结果如下： ( 1 ) uv - b辐射处理后前2天，紫萍超氧化物歧化酶( sod )和抗坏血酸过氧化物酶( ap )等抗氧化酶系统有不同程度的升高，随着uv - b处理时间的延长，紫萍体内抗氧化保护系统能力下降， sod和ap的活性下降，并且非酶类抗氧化物质抗坏血酸( asa )含量一直低于对照组，而脯氨酸( pro )的含量则一直在升高。 - Second , the activities of protective enzymes i . e . superoxide dismutase ( sod ) , peroxidase ( pod ) , and ascrobate peroxidase ( apx ) exhibited down - up - down trends when treated with 2 @ and 8 @ , and these activities sustained at a relatively high level . this indicated euonymus japonicus " zhuzi " had relatively high adaptability to cold stress
( 2 ) ‘粗枝’大叶黄杨在零上低温时，细胞保护酶超氧化物歧化酶( sod ) 、过氧化物酶( pod ) 、抗坏血酸过氧化物酶( apx )的活性先降低后上升，又下降并维持较高的水平，表明‘粗枝’大叶黄杨对低温胁迫有一定的适应性。 - According to the research of physiological and biochemical indicators or index , components of soluble proteins , substrate protein of phosphorylation and the activity of protein kinase in low - temperature stress in the leaves of brassica oleracea l . , we tried to find the law of the physiological and biochemical response of brassica oleracea l . leaf to low temperature . at the same time , discussion on the signal transduction can also provide further evidences for revealing the mechanism of low - temperature stress . the results are showed as follows : malondialdehyde ( mda ) , superoxide dismutase ( sod ) , ascorbate peroxidase ( asp ) and peroxidase ( pod ) activities were changed greatly after 0 ~ 30min ' s treating with low temperature
本文以甘蓝叶片为材料，通过对低温5胁迫下甘蓝生理生化指标、可溶性蛋白组分以及磷酸化底物蛋白、蛋白激酶活性的研究，以期找出甘蓝叶片对低温胁迫的生理生化响应规律，为甘蓝露地越冬栽培防范寒害提供理论指导，同时对低温胁迫下甘蓝逆境信号传导进行了探讨，从而为彻底弄清低温胁迫机理提供进一步的证据，研究的主要结果如下：丙二醛含量( mda ) 、超氧化物歧化酶( sod ) 、抗坏血酸过氧化物酶( asp )和过氧化物酶( pod )活性在低温处理0 30min发生显著变化，低温处理3min后，甘蓝叶片内mda含量基本没有变化，处理5min时出现第一个峰值，达到对照的104 . 10 ， 10min出现低谷，仅为对照的86 . 27 ，随后再次上升， 30min时超过第一峰值，为对照的113 . 93 。
