干旱是影响玉米产量最主要的非生物胁迫因子。综述玉米耐旱性评价研究进展,对目前耐旱鉴定研究过程中存在的问题进行探讨,提出玉米耐旱鉴定应采取以产量性状为评价指标的直接评价和以生理生化或形态性状为评价指标的间接评价相结合策略。
Drought is the most important abiotic stress factor affecting maize yield. This paper reviewed the research progress of drought tolerance evaluation in maize and discussed the existing problems in drought tolerance identification research. It was suggested that drought tolerance identification should be based on the direct evaluation of yield traits as evaluation index and the physiological, biochemical or morphological traits as evaluation index Indirect evaluation combined with the strategy.
