【摘要】 研究１１份禾草种质料的开花习性表明：稗草、长叶雀稗及草芦的小花开放顺序，通常由顶部向基部开放，而庐山草芦及鸭茅则表现为由中上部位向上、下两端开放。单个花序开花持续时间在７～３２天。除草芦外，其余各属饲草的不同草种间小花开部特点相似。３种稗草有部分小花闭颖授粉结实。庐山草芦一日开花高峰在下午１４～１５时，其余均在上午，多数在８～１０时。更多还原

【Abstract】 The flowering behavior of 11 grasses was studied.The result showed that the opening order of their flowerets of Echinochloa, Pasplum and Phalaris was usually from terminal to basal but Lushan and Dactylis from middle-upper to the two ends.The floweriiig duration time of per spike is 7 to32 days.The characteristics of their flowerets from opening to shutting is simlliar.Some of the three grasses of Echinochloa can seed no floweret opening.The flowering tiiT1e of P. sp of Lushan is mainly at 14 :00～15:00everyday,and the other mainly at 8:00～10:00.更多还原
