臭氧胁迫对大豆根系激素含量和活性氧代谢的影响
Effects of ozone stress on soybean roots endogenous hormones and reactive oxygen metabolism
摘要
Abstract
The effects of O3 concentration elevation 〔(80 ± 10) nL・L-1〕 on soybean roots endogenous hormones and reactive oxygen metabolism was studied in this paper .Compared with the control ,the elevated O3 concentration in-duced an increase of abscisic acid (ABA) content and Zeatin riboside (ZR) content ( P<0 .05) ,and a decrease of growth hormone (IAA) content (P<0 .05) .The balance of endogenous hormones was changed ,and the specific value of IAA/ABA ,AR/ABA and (IAA+ZR)/ABA was decreased ( P<0 .05) .The production rate of superoxide anion , the malondialdehyde (MDA) content POD activity and the proline content were increased (P<0 .05) and the SOD and CAT activity were decreased (P<0 .05) .To a certain extent ,ozone stress changed the soybean endogenous hormones level and balance and improved its antioxidant ability .However ,constant ozone stress could cause the anti-oxidant sys-tem damage ,exacerbate the membrane lipid peroxidation ,and injure the soybean .关键词
