| 摘 要： | 以辽宁省不同年代直立穗型代表品种为材料,比较研究了直立穗型粳稻齐穗期株型相关性状的表现及差异。结果表明,直立穗型粳稻存在多种穗型类型;品种间水稻茎叶绿叶数、叶长配置不同,叶宽变异较大,造成绿叶叶面积差异;植株叶片挺立,剑叶、倒2叶叶基角小于14°,从倒3叶开始下部茎叶叶基角、披垂度变大;少分蘖品种下部茎叶披垂度相对较大,叶片叶绿素含量高,株间透光率高,因此具备较好的干物质基础。

| Abstract: | The Japonica rice varieties with erect panicle type in different periods in Liaoning Province being taken as trial material,the characters and difference of Japonica rice plant type with erect panicle type in the ripening period were comparatively studied.The results showed that: there were different kinds of panicle types in erect panicle type.In varieties the variance of leaf number,leaf length and leaf width existed,which made the difference of the green leaf area.Leaves were erect in the plant.The leaf basic angle of flag leaf and top second leaf was less than 14°,from top third leaf to the lower leaf the leaf basic angle and leaf drooping degree become bigger.In less tiller varieties the drooping degree of the lower leaves were relative bigger,and its chlorophyll content and transmit light rate were higher.So it had the good base of dry matter accumulation. |
