镉胁迫对龙葵生长、质膜atp酶活性及氮磷钾吸收的影响
DOI: 10.3724/SP.J.1145.2014.07028, PP. 121-128
Keywords: 龙葵,镉胁迫,质膜过氧化,养分吸收,atp酶活性,抗氧化酶
Abstract:
采用模拟镉（cd）污染土壤培养法研究不同浓度cd（0、10、20、40、80、160mgkg？1）处理对cd超积累植物龙葵（solanumnigrum）幼苗营养元素氮（n）、磷（p）、钾（k）吸收及质膜atp酶活性的影响.结果表明，cd处理浓度≤40mgkg？1时显著促进龙葵幼苗的生长（叶性状、主根长、株高度和基径粗度）以及生物量的积累与分配；而当cd处理浓度＞40mgkg？1时则出现明显的抑制作用.而当cd处理浓度为10mgkg？1时，则提高显著幼苗叶片叶绿素（chl.a、chl.b、chl.[a+b]）含量，达到最高值；且叶绿素含量随胁迫程度的增强而先升后降.随胁迫程度的增强，幼苗根、茎、叶和果实中的n、p和k含量先升后降（除茎p降低外）；而植株组织中的cd积累量逐渐增大且分布为叶＞茎＞根＞果实.同时，丙二醛（mda）含量与过氧化氢酶（cat）和超氧化物歧化酶（sod）活性随cd浓度增大而增大，但超氧化物歧化酶（pod）活性先升后降.随胁迫程度的增强，幼苗地上（茎与叶）和地下（根）部h+-atp以及地下部ca2+-atp酶活性不断降低，而地上部ca2+-atp酶活性先升高后降低.因此，龙葵在高浓度cd胁迫（≥40mgkg？1）下，可能通过加快根对cd离子的吸收和转运，提高抗氧化酶（cat和sod）活性，降低pod与质膜atp酶活性，调节对n、p和k的需求，从而起到对cd胁迫的解毒作用.
