褪黑素在果樹(shù)響應(yīng)鹽堿脅迫中的作用研究進(jìn)展

摘 要：土壤鹽堿化是影響果樹(shù)產(chǎn)業(yè)發(fā)展的重要限制因素之一。概述了土壤鹽堿脅迫對(duì)果樹(shù)的危害，闡述了褪黑素響應(yīng)果樹(shù)鹽堿脅迫的途徑及其作用機(jī)制，展望了外源褪黑素在果樹(shù)響應(yīng)鹽堿脅迫方面的應(yīng)用，以期為鹽堿地果樹(shù)生產(chǎn)提供指導(dǎo)。

關(guān)鍵詞：土壤；鹽堿化；脅迫；果樹(shù)；褪黑素

Abstract：Soil salinity is one of the important limiting factors affecting the development of fruit tree industry. This article provides an overview of the harm of soil salinization stress to fruit trees， elucidates the pathways and mechanisms of melatonin response to fruit tree salinization stress， and looks forward to the application of exogenous melatonin in fruit tree response to salinization stress， in order to provide guidance for fruit tree production in saline alkali soil.

Keywords：soil; salinization and alkalization; coercion; fruit trees; melatonin

據(jù)FAO統(tǒng)計(jì)，我國(guó)鹽堿地總面積達(dá)9 913萬(wàn)hm2，主要分布在東北、華北、西北、長(zhǎng)江中上游及濱海新區(qū)，分布范圍廣，面積大［1］。（剩余11737字）
