The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。

In Huang-Huai-Hai region, the focus was to strengthen the cultivation and management to reduce yield gap between test and field production, because there were a high scientific and technological level but shortage of water, etc. In middle and lower reaches of the Yangtze River region, the focus was to strengthen the ability of drainage and avoided water-logging etc. In north-eastern region, the focus was to avoid drought and high-temperature damage, sometimes spike-sprouting caused by rain pre-harvest.

黄淮海优势区灌溉水短缺，干旱、干热风等自然灾害频发，但小麦科技实力较强，育种和栽培研究水平相对较高，要加强栽培管理缩小试验地产量与大田产量的差距；长江中下游小麦优势区排涝和降渍能力比较弱，渍害、穗发芽时有发生；东北小麦优势区干旱和高温频发、收获前常遇阴雨导致穗发芽；西北小麦优势区土壤瘠薄、干旱少雨；西南小麦优势区日照不足、雨多雾大晴天少，易旱易涝等。

地毯草群落结构中主要的优势植物种有竹节草、狗牙根、假俭草、双穗雀稗、两耳草以及百花地胆头等，其中以地毯草＋竹节草＋双穗雀稗和地毯草＋竹节草＋狗牙根两种群落组成类型较多。

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

Spikelets 4–5 mm, dark brown, pallid near apex, keels green; callus hairs 1/2 spikelet length; lower glume lanceolate, back flat, densely hairy with silky hairs ca. 1.5 times spikelet length or more, veinless between keels, apex obscurely emarginate or 2-mucronate; upper lemma narrowly oblong, shortly 2-toothed; awn 0.8–1.5 cm, fine, almost straight.

300 pieces of idioplasm resources of the Tibetan edible cultivation spring naked barley is identified for characteristic of shape, agronomic characters, rust-resisting property and grain thick protein,β-grape polymerization sugar and Vitamin E and so on from the Tibetan different region, which are analysed result in, for one thing, multiplicity of Tibetan spring naked barley is quite rich for the variation of the awn, leaves and the grain color, and multiple property are highest; Secondly, it has some fine hereditary characters of early maturation, big spike, many grains, many arrises and the strong anti-rust quality; Thirdly, genetic potential which is used possibly is enormous for characteristic of dense spike, exiguous spike, naked grain , the hook awn, short stem, the anti-rust and so on ; Fourthly, thick protein,β-grape polymerization sugar and Vitamin E of grains are rather difference to environmental condition of the various areas.

从西藏各地征集的300余份食用栽培春青稞种质资源，从形态特征、农艺性状、抗锈性和籽粒粗蛋白、β-葡聚糖含量、维生素E等特征特性鉴定、评价。分析结果认为：（1）西藏春青稞多样性极为丰富，如芒、稃和籽粒颜色，具有变异最为丰富，多样性最高的特点；（2）具有早熟、大穗、多粒、棱型多，以及抗锈性强等和耐各种不良环境因素的优良遗传性状；（3）具有密穗、稀穗、裸粒、钩芒、矮生、抗锈等可利用基因潜力巨大等特色；（4）籽粒粗蛋白、β-葡聚糖、维生素E等成份因各地区环境条件不同差异较大。

Here were two ways to increase TGN. One was to increase EN unit area; the other was to increase GN by adapting floribunda type maize and raising floret pregnancy rate.

GN的提高：一是通过增加密度提高单位面积收获穗数，二是通过采用多花型品种和提高小花受孕率提高穗粒数实现。

Pictum were treated with different concentrations of solutions 1 (1% Triadimefon + 15% Ethylicin WP) and 2 (15% Carbendazim + 15% Thiram WP) for 3 hours, respectively.

However, it is seldom necessary to dissect the spikelets in order to identify a member of Andropogoneae .

The小穗包含2小花，不过，为了鉴定一名Andropogoneae的成员对多裂小穗很少必要。
