Abstract:

以湿地植物菖蒲为研究对象,在水培条件下观察3个浓度梯度的氮磷污水(处理组1、2、3依次为N:40mg/L、P:4mg/L;N:80mg/L、P:8mg/L;N:120mg/L、P:12mg/L)对其胁迫后的根系释氧和通气组织的变化规律,研究发现高氮磷胁迫明显抑制菖蒲株高和根系长度的生长,减少植物根系数量;高氮磷胁迫还可以增加植物根系释氧量和促进根系通气组织形成,由于根系长度和数量的减少,处理组的根系释氧总量不及对照组;高氮磷胁迫不改变菖蒲根系释氧趋势,根尖最大,离根尖越远释氧越小.研究还发现,根尖释氧量大小和通气组织呈正相关,根基和根中部释氧量与通气组织关系不显著,说明植物通气组织的形式更有利于根尖释氧.
