Inflorescences aggregations of sessile florets in spikelets or pseudospikelets, branching absent to compound, bracteate or ebracteate; spikelets prophyllate or not, glumes often poorly distinguished from basal bracts and lemmas, not subtending viable buds or branches, or in pseudospikelets subtending axillary buds capable of partial or extensive spikelet ramification; lodicules absent to very many, usually 3, usually ciliate, veined, posterior lodicule usually narrower than anterior pair.
花序(更多的correctlysynflorescences)集中的无梗小穗或复合的分枝无到,pseudospikelets小花,或无苞片;小穗先出叶与否,从基部的苞片和外稃卓越的不好的颖片通常,通常,许多的鳞被无到,通常具缘毛,,通常比前面对狭窄的后唇瓣鳞被。

The effects of different plant densities on flag leaves chlorophyll content,SOD activity and MDA content after anthesis in stronggluten wheat interplanted in paddyfield were studied.
本试验在江苏淮北地区设计不同密度试验,研究其对稻田套播强筋小麦花后剑叶叶绿素含量、SOD酶活性和MDA含量的影响,结果表明:随花后生育进程推移,叶绿素含量呈下降趋势,且随密度增加,下降幅度增大;花后单茎干物质积累量和单茎籽粒产量亦随密度增加而下降,二者呈极显著负相关;随花后生育进程推移,剑叶SOD酶活性呈单峰曲线变化,可用二次曲线方程模拟,在花后1416 d达峰值,且随密度增加峰值出现时间提前,峰值数值呈先上升再下降的变化特征;随花后生育进程推移,剑叶MDA含量呈上升的变化特征,且随密度增大,数值变大;花后35 d剑叶SOD酶活性与花后单茎干物质积累量和单茎籽粒产量呈极显著正相关,而MDA含量与花后单茎干物质积累量和单茎籽粒产量则呈显著或极显著负相关。
