【摘要】 全球气候变化的长期趋势预示着将出现更多的易发生干旱的区域,伴随着玉米生长区域的不断扩张,干旱的发生可能会导致粮食产量的不稳定性增强,甚至危及地区及全球的粮食安全。产量下降的程度不仅取决于干旱的严重程度也取决于作物所处的生长阶段。本研究试图从玉米植株形态、产量和产量构成、生理指标和后续生长发育指标以及可恢复能力等几方面,就土壤水分胁迫对玉米生长发育的影响进行了综述,同时就水分胁迫影响的研究方法及玉米对水分胁迫的响应及适应方面也做了阐述,提出了进一步开展相关研究应重点关注的几个方面。更多还原

【Abstract】 Long-term trend of global climate change indicated that more areas would be involved in arid disaster. This would increused the instability of crop yield with the extending of maize planting area, even endanger the regional and global food safety. Reduction of maize yield resulted in arid was determined by not only severity of arid but also the growth or development stages when arid occurs. This paper reviewed the influences of soil water stress on growth and development of maize in several aspects, including plant configuration, yield and yield elements, physiological indexes, growth and development indexes and restorable ability and so on. The research methods and response and adaptation of maize to water stress were also reviewed. And some stresses on future researches were suggested.更多还原
