1.【植】颖,颖片
1.either of a pair of dry leaves at the base of the spikelet in an ear of a grass or cereal plant
1.Lower glume separated by an internode; spikelets not in pairs, evenly spread throughout the panicle.
一节间分开的更低的颖片；不成对的小穗，在整个圆锥花序平均平展。
2.Upper glume subequaling spikelet; only branch or branchlet tips extending into a bristle, rarely a solitary bristle below a few spikelets.
近相等的上面颖片小穗；只分枝或小枝端部延长成为一刚毛，很少在一些小穗下面的一单生刚毛。
3.Lower glume not separated by an internode; spikelets in pairs and clustered toward the ends of the branches.
更低的颖片不被一节间分开；成对的小穗和对于分枝的末端的簇生。
4.Secondary branches well developed, spreading; lower glume separated by an internode.
次生分枝发育良好，平展；一节间分开的更低的颖片。
5.The long filiform glume tips are readily broken off, so that the spikelets appear to be much shorter.
长丝状的颖片端部被容易停止，小穗看起来是非常短。
6.After the larvae invaded into the glume, the main factors reducing the yield loss rate of wheat belong to antibiotic or tolerant resistance.
因此认为抑制初孵幼虫浸入后小麦损失率的主要原因是抗生性和耐害性。
7.Lower glume separated by an internode; upper lemma glabrous at the apex.
一节间分开的更低的颖片；在先端无毛的上面外稃。
8.The length of the lower glume is very variable, even within a single raceme.
更低的颖片的长度非常易变，即使在一单个的总状花序内。
9.Upper glume clearly mucronate, shorter than spikelet; spikelets planoconvex, acuminate; back of upper lemma lying against rachis.
明显短尖的上面颖片，短于小穗；小穗平凸，渐尖；在对轴躺的上面外稃后面。
10.Lower glume of sessile spikelet obovate, broadly winged; awn present, geniculate, exserted from spikelet.
倒卵形的无梗小穗，具宽翅的下部颖片；从小穗存在，膝曲，外露的芒。
