Within this pattern, the Cypereae spikelets show variations in (Tables 1 and 2): (A) number and phyllotaxis of the glumes; (B) presence of empty glumes (lack of development of flowers in lower or upper glumes); (C) glume morphology; (D) rachilla internode length; (E) prophyll development; (F) flower structure; (G) structure of the dispersal unit.
Spikelets with unequal and acuminate glumes; lower glume 2-2.7 mm long; upper glume 3.3-4.3 x 1.3-1.6 mm, acuminate.
SEM images clearly show that the glumes and sterile lemma are densely pilose with long clavate macrohairs which have a bulbous truncate or slightly rounded tip (Fig.
the traits sere as follow: The height of the bush, the length of ears, number of claw, straw weight, seed yield in bush, glume, ear density, number of days till appearance of ear, number of days till physiologic growth, need to making spring cultivar, total dry matter and harvest index.
In the traits like glume, spring cultivar, and ears density; the hypothesis of the inheritance of the one gene was tested by [X.sup.2],.
Lower glume 2-3.4 x 0.6-0.8 mm, slightly concave, lanceolate, chartaceous, glabrous on the margins, 2-3 nerved, acute apex; upper glume (2.1-) 3-4 x 0.7-0.9 mm, sub-chartaceous, ciliate on the upper half of the margins, 3-nerved, the lateral nerves tenuous, acute apex.
Within the first component, which accounted for 45% of the variation, spikelets [spike.sup.-1], first and second glume length and width, lemma length and width all had factor loadings > 0.82.
In the last branching order (spikelet), the glume phyllotaxis can be either spiral (e.g.
First glume chartaceous, 2-keeled, 2-nerved, 1.3-2 mm wide, flat to slightly concave, glabrous, the tip scabrous, the margins inflexed, firmly clasping the second glume.
The glume is midlong and narrow, and the glume shoulder is narrow to midwide and square.
The flower is subtended by the spikelet prophyll, which forms an utriculus that envelops flower, rachilla and distal glume (Fig.
