The results were as follows. Treatment with 10 % of seawater did not damage the chloroplast and mitochondrion of aloe seriously , but chloroplast became expanded and mitochondrion membrane turned out illeg ible when the aloe was treated with 30 % of seawater. Compared with the control (treatment with Hoagland) , there was not significant de crease of chlorophyll a and chlorophyll b in aloe treated with 10 % of seawater , while significant decline of both chlorophyll a and b in aloe treated with 30 % of seawater.
