| 摘 要： | 采用分根装置,在均匀灌溉、固定灌溉和交替灌溉3种方式下,分区测定轻、中、重度3种胁迫条件下以及复水后玉米根系的丙二醛MDA含量、过氧化物酶POD和超氧化物歧化酶SOD活性。不同于以往的分根交替灌溉研究的内容,重点研究在局部灌水条件下玉米根系对干旱及复水的生理生化响应。研究结果表明,无论干旱还是复水后,固定灌水条件下,作物根系受活性氧伤害较之均匀灌水增大,而交替灌水使作物受活性氧的危害减小,这对交替灌溉的节水效应的进一步研究具有重要的意义。 |

| Abstract: | Effect of different irrigation methods on physiological and biochemical response of maize root to drought and rewatering was studied.Plants were raised in split-root containers and irrigated on both halves of the container(conventional irrigation,CI),on one side only(fixed partial root zone irrigation,FPRI),or alternatively on both sides(alternate partial root zone irrigation,APRI).Plants were subjected to mild or moderate or severe water stress and drought treatment began at shooting stage.Malondialdehyde(... |
