Abstract：Taking Solanum torvum as stock and early maturing cultivated variety 'Jingqie No. 1’
as cion, this experiment analyzed the yields and mineral element contents of the grafted eggplant
（Solanum melongena L.） and self-rooted eggplant by treatments of different seawater concentration．
The results indicated that compared to the self-rooted eggplant，the content of N，P in grafted eggplant
was increased along with the increase of seawater concentration，while the K content showed reducing
tendency．The grafted eggplant could still maintain balanced absorption of Ca, Mg, Cu, Fe, Zn and Mn
in the seawater，but the ratio of Na+/K+ value decreased significantly．The yield of grafted eggplant was
significantly higher than that of the self-root eggplant under seawater stress．The experiment showed
that the grafted eggplant could reduce the complex salt stress of sea-water through adjusting mineral
elements absorption，and increase eggplant yield.
