| 摘 要： | 以野生茄子托鲁巴姆为砧木，以栽培种早熟京茄1 号为接穗，采用不同的海水浓度处理，对 嫁接茄和自根茄的产量和矿质元素含量进行了分析。试验结果表明：与自根茄相比，嫁接茄N、P 含量 随着海水浓度的升高而升高，K 含量随着海水浓度升高有降低的趋势，在海水中仍能维持Ca、Mg 和Cu、 Fe、Zn、Mn 微量元素的均衡吸收，Na+/K+值显著降低；在正常营养液栽培和海水胁迫下，嫁接茄的产量 都显著高于自根茄。说明嫁接茄能够通过对各矿质元素的调节吸收来减轻海水复盐胁迫，从而提高茄子的 产量。 |
| 关 键 词： | 嫁接茄 复盐胁迫 产量 矿质元素 |

| 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. |
