| 摘 要： | 向日葵作为我国五大油料作物之一，具有极高的食用价值和油用价值。向日葵在我国的种植分布集中在东北、西北和华北地区，时常面临着干旱、盐碱、温度和重金属胁迫的问题。主要综述了近年来向日葵面临的几种主要逆境胁迫的最新研究进展，以及在不同逆境胁迫下向日葵的耐受机制，并根据不同逆境胁迫筛选出了相应的抗逆向日葵品种，同时进行了生理差异和基因信息分析。通过阐明向日葵在逆境胁迫下的耐受机制，以期对向日葵高产育种及耐逆育种提供理论依据和指导方向。

| Abstract: | Sunflower， as one of the five oil crops in China， has high edible value and oil value. Sunflower planting distribution in China concentrated in northeast， northwest and North China， which often faced with drought， saline-alkali， temperature and heavy metal stress problems. This paper mainly summarized the newest progress of several kinds stress in sunflower， and the tolerance mechanism of sunflower in different stress response. By elucidating the tolerance mechanism of sunflower under abiotic stress， the paper was expected to provide theoretical basis and direction for high yield breeding and inverse breeding of sunflower. |
