摘 要 ：在水培和盆栽条件下，研究了6个水稻品种(含籼/粳杂交组合、新株型品系)结实期强、弱势粒和根系中玉米素(Z)与玉米素核苷(ZR)含量的变化及其与籽粒充实的关系。籽粒中Z+ZR含量在开始灌浆时很低，随灌浆进程Z+ZR含量增加，达到峰值(强势粒在花后9～15d，弱势粒在花后12～21d)后迅速下降。根系中Z+ZR含量在抽穗时就很高，在花后

Abstract:Six rice cultivars (including 2 japonica/indica hybrid combinations and 1 new plant type line ) were grown in water culture in the green house /or in pots in the screen house. Zeatin (Z) and Zeatin riboside (ZR) contents in grains and roots during grain filling were measured with an enzyme-linked im
