摘要
赖草是一种抗逆性极强的多年生禾本科植物,具有耐盐碱、耐旱、耐瘠薄、耐寒、耐风蚀、耐污染、耐沙埋、耐暴雨等特点,不仅是一种饲用价值较高的优良牧草,还是进行植物新品种培育的一种基因库材料。本文综述了赖草的优良特性、干旱胁迫下的生理变化、抗旱机制及抗旱相关基因的研究进展,并提出了今后的研究趋势。
Leymus is a perennial gramineous plant with strong resistance ability such as salt tolerance, drought resistance, cold tolerance, barren resistance and so on. Leymus has better feeding value, and is a gene bank accession breeding new plant variety. In the paper reviewed the better characteristics of Leymus, physiological change under drought stress, drought-resistance mechanism and drought-resistance genes research, and put forward its research tendency in the future.
