    摘要:

    油菜在整个生育期中对水分要求严苛,而随着全球气候变暖及强降雨事件的发生,油菜生产环境恶化,干旱和淹水交替发生,对油菜的生育进程及代谢过程产生了显著影响,使油菜产量降低、品质变劣。一播全苗是作物高产稳产的基础,油菜播种后的水分条件很大程度决定了成苗数量,而成苗后各生育期的水分条件在油菜生产中的作用同样不容小觑,决定了油菜最终的生产效益。在面临水分胁迫的过程中,油菜根系优先感应到干旱/淹水信号,同时地上部发生气孔关闭、光合作用减弱及渗透调节等一系列生理反应,地上部地下部同时启动相应机制以对抗水分逆境,而现有的研究中尚未对油菜根-冠互作进行深入剖析。

    Abstract:

    Rapeseed is the world’s third largest oil crop,an important source of producing plant oil with highquality and feed protein,and has become one of the most valuable trade agricultural products. Rapeseed strictly requires water at each stage of growth and development. With the occurrence of global warming and heavy rainfall events,the environment of rapeseed production has deteriorated. The alternation of drought and flooding has a significant impact on the growth process and metabolic process of rapeseed,and ultimately reduces the yield and quality of rapeseed. “One sowing and all seedlings” is the basis for the high and stable yield of crops. The water condition of rapeseed after sowing largely determines the number of seedlings. The effect of water condition at each stage of growth and development after seedlings on rapeseed production cannot be underestimated,which determines the final production benefit of rapeseed. Under water stress,the drought (flooding) signal is first sensed by the root system of rapeseed. At the same time,a series of physiological reactions including stoma closure,weakening of photosynthesis and osmotic adjustment occur in the aboveground part of the plant. The aboveground and underground parts of plant simultaneously activate corresponding mechanisms to resist water stress. However,studies about indepth analyses of the rootshoot interaction of rapeseed are rare.
