丛枝真菌对Pb胁迫下烟草的解毒效应
Detoxification effect of inoculation arbuscular mycorrhizal fungi with tobacco on its Pb stress
摘要
Abstract
To study effects of inoculation arbuscular mycorrhizal fungi with tobacco on detoxification Pb stress,a pot experiment was carried out with tobacco (Nicotiana tabacum L.) and Glomus intraradice.The result showed that,under Pb stress,after inoculation Glomus intraradice with tobacco,Pb contentdecreased in leaves,but significant increase in roots.The H2O2 content and production rate of superoxide aninwere decreased significantly,and the activity of SOD,CAT,APX,POD and MDA content decline accordingly.As glyoxalase I activity was enhanced and glutathione content increase in the leaves,the potent cytotoxic compound methylglyoxal decreased.The result indicated that inoculation arbuscular mycorrhizal fungi with tobacco could reduce oxidative stress and content of Pb in leaves,and consequently raise the quality of tobacco.关键词
