摘 要：<正> The effect of lanthanum ion on membrane permeability of corn root segment is studied.Results shows thattreatment of the root segments with LaCl3·7H2O can decrease the ion leakage of the root tissue.The leakagedecreases hy increasing the concentration of lanthanum,and the concentration has no further dependence on ionleakages above 25 μmol/L.After treating the root tissue for one hour with lanthanum ion,the amount of leak-age has linear dependence on time within the first 2 h and after two hours the leakage increases.The ion leakageof the tissue dependes on the time of lanthanum treatment.When the duration of treatment is prolonged,theleakage decreases rapidly and the leakage reaches a minimum at 30 minutes.Other rare earth elements can alsodecrease ion leakage.There is no significant difference in the ion leakage among these elements.
