鹽堿脅迫對果樹的危害及其分子機(jī)理研究進(jìn)展

摘要：鹽堿脅迫是影響果樹生長發(fā)育最嚴(yán)重的限制因子之一。果樹受鹽堿脅迫后根系生長受阻、葉片變小、發(fā)育遲緩，造成植株矮化、早衰甚至死亡。從細(xì)胞膜透性、POD、SOD等生理特性方面分析了果樹對鹽堿復(fù)合脅迫的響應(yīng)機(jī)制，多角度分析了果樹抗鹽堿的分子機(jī)理。

Abstract：Salt-alkali stress is one of the most serious limiting factors affecting the growth and development of fruit trees. The root growth of fruit trees under salt-alkali stress was blocked， leaves became smaller， growth retarded， resulting in plant dwarfing， premature senility and even death. In this paper， the response mechanism of plants to salt-alkali combined stress was analyzed from the aspects of osmotic regulation， cell membrane permeability、 POD、 SOD、 etc. And the molecular mechanism of salt-alkali resistance of fruit trees was summarized from various angles.

Key words：Fruit tree;Salt and alkali stress;Physiological characteristic;Molecular mechanism
