水稻根系形态生理应答盐胁迫与氮肥调控的生理机制研究进展
Research Progress of the Physiological Mechanism of Rice Root Morphology and Physiology Response to Salt Stress and Nitrogen Regulation
摘要
Abstract
Recently,salinity stress has become one of the major constraints to crop production caused by soil salinization even worse than ever before and saline-alkali land area expanding more quickly.It is of great significance to explore the mechanisms of plants response to salt stress and regulate crops to salt tolerance production in order to ensure food security.Rice is the main staple food for human diet and it is sensitive to salinity.Root system is the main organ which plant used to seedling establish,and absorb water and nutrients,and directly involved in many kinds of growth metabolism.In salinity conditions,rice roots are the first to sense salt stress,which affects root morphology and nutrient uptake,resulting in insufficient nutrient supply to plant growth and lead to yield reduction.Therefore,it is vital to study the effect of salt stress on root morphology and physiology traits of rice and the related mechanisms for crops to regulate salt tolerance.In this paper,the effects of salt stress on root morphological construction,root physiological activity and related physiological metabolic pathways were reviewed,the relationship between root morphology and physiology and plant growth and yield formation was analyzed,the physiological mechanism of nitrogen management to al-leviate salt stress to rice root was summarized.And the future research directions were prospected.The aim of the paper was to provide a new reference to breed salt-tolerant rice genotypes and develop salt-tolerant cultivation technology.关键词
