摘　　要：为进一步提高杂交水稻 W6 1 5 4 S/早特青的产量 ,从源库特征及维管束特性等方面对其结实率进行了研究 .结果表明 ,W6 1 5 4 S/早特青比汕优 6 3具有明显的产量优势及超高产潜力 ,但结实率较低 ,其原因主要是源的供应不足 。To promote the yield of hybrid rice W 6154S /Zaoteqing,the setting percentage of this rice was studied from the angle of source and sink character and vascular bundle.The results show that W 6154S /Zaoteqing yields more and bears more potential of super high yield compared with Shanyou63.Its low setting percentage is due to the unharmony between source and sink as well as translocation system,and undeveloped of vascular bundle in low position branches.
