氮对超积累植物东南景天生长和镉积累的影响

open access: yesShuitu Baochi Xuebao, 2007
通过水培试验,研究了氮素水平对超积累植物东南景天植株生长和镉吸收积累的影响。结果表明,在一定范围内供氮(4.0-16.0 mm ol/L)能明显促进东南景天的生长,随着氮素水平的升高,地上部和根系的生物量也提高,在供氮水平为16.0 mm ol/L时达到最大值,而当供氮水平≥32.0 mm ol/L时,东南景天的生长受到严重的抑制,其地上部和根系的生物量开始下降,各项根系形态的指标(包括根系长度、根系表面积、根系直径、根系体积)均有所降低。氮对东南景天体内镉积累有一定的促进作用,随着氮素用量的增加 ...
