摘要: 玉米粒重由库容大小和库充实度决定,两者受籽粒和植株体内同化物供应和激素代谢水平的影响。在综述了粒重形成过程,介绍了各种环境因子(温度、水分、光照等)和栽培措施(营养元素、植物生长调节剂等)对库容建成和库充实度的影响的同时,分析了控制粒重增加的生理原因。

Abstract: Grain weight of maize is determined by the sink establishment, grain filling rate and filling duration. Environmental and cultivating factors (such as temperature, water, fertilizer and plant growth regulators) can influence such process by regulating the carbohydrate metabolism and hormone level in the plants. The key point of further study on grain weight was discussed.
