摘 要 ：雄性不育水稻包颈是影响杂交种子生产的重要因素。隐性长穗颈（eui）基因具有减轻或完全解除雄性不育水稻包颈的作用。但不同播期的具隐性长穗颈基因的光温敏核不育水稻包颈程度变化较大，为了揭示影响这类不育系包颈程度变化的原因，本文以隐性长穗颈光温敏核不育水稻为材料，分析了花粉育性与穗颈节伸出剑叶叶鞘长度的关系

Abstract:Panicle enclosure is a typical phenotype of almost all male-sterile lines, which greatly reduces seed production of hybrid rice due to its blocking of normal pollination. Therefore, large amount of exogenous GA has to be used for inducing panicle exsertion. However, GA application not only increases
