Abstract
Roots of taro (Colocasia esculenta [L.] Schott cvs Bun-long and Lehua maoli) exuded increasing concentrations of oxalate with increasing Al stress. This exudation was a specific response to excess Al and not to P deficiency. Addition of oxalate to Al-containing solutions ameliorated the toxic effect of Al.
摘要
芋头（芋头品种邦隆和毛里乐华）的根系随着铝胁迫的增加而分泌出浓度不断增加的草酸盐。这种分泌是对过量铝的特异性反应，而非对磷缺乏的反应。向含铝溶液中添加草酸盐可减轻铝的毒性作用。
