The result indicated, the CIMMYT forage characteristics of the overgrowth, strong tillerity and high yield could inherit to the offspring ,and the inherit ability was higher. It was obviously difference of seedling, plant, and its grow habit, flower apparatus and seed between CIMMYT forage and common maize. The hybrid offspring of CIMMYT forage and common maize keep the strong trait of growing and development, but the flower and seed character were look like common maize. The backcross offspring were not different to common maize besides with some tillers, distinct multi-ear and atavism.

结果表明，CIMMYT牧草能将其生长繁茂、分蘖力强、生物产量高的特性遗传给杂交后代，并有较强的世代传递能力；该牧草幼苗、植株及其生长习性、花器官、种子特征等与普通玉米差异明显，其与普通玉米的杂交后代基本保持了它的生长发育特性，但花器官和种子特征更偏向于普通玉米；回交后代除保持了一定的分蘖特性、明显的多穗和返祖现象外，其余特征特性与普通玉米基本没有区别。

Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...

用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

Peneleos then drew his sword and smote him on the neck, so that both head and helmet came tumbling down to the ground with the spear still sticking in the eye; he then held up the head, as though it had been a poppy-head, and showed it to the Trojans, vaunting over them as he did so."Trojans," he cried, bid the father and mother of noble Ilioneus make moan for him in their house, for the wife also of Promachus son of Alegenor will never be gladdened by the coming of her dear husband- when we Argives return with our ships from Troy.

裴奈琉斯拔出利剑，劈砍在脖子中间，人头落地，连着帽盔，带着粗长的木杆，枪尖仍然扎刺在眼窝里，裴奈琉斯高挑起人头，像一束罂粟的头穗，展现给特洛伊人视看，放声吹擂：尔等特洛伊人，代我转告高傲的伊利俄纽斯亲爱的父母，让他们开始举哀，在自家的厅堂里，既然阿勒格诺耳之子普罗马科斯的妻房亦不再会有眼见亲爱的夫婿回归的激奋，在我们阿开亚人的儿子们，乘坐海船，从特洛伊返航回家的那一天！

Spikelets with 1 floret, mostly laterally compressed, rachilla extension absent, falling entire; glumes absent or reduced to small scales at base of floret; lemma membranous to leathery, keeled, 5–10-veined, entire, with or without a straight awn from the apex; palea resembling lemma but narrower, 3–7-veined with central keel.

小穗具1小花，多数侧面压扁，小穗轴扩展无，变为全缘；颖片小花的无的或退化至小鳞片在基部；外稃膜的到革质，翻转，5-10脉，整个，有或没有来自顶的一直的芒；内稃象外稃但是狭窄，3-7脉与中心的龙骨一起。

Oil pollutants not only impact wheat emergence, plant height, panicle length but also the germination rates of corn, soybean and cotton seed which is the impacted mostly. Through field comparative analysis between apple trees near wells and those without pollution, index of leaf senescence of fruit trees, apple leaf chlorophyll content and nutrient composition are impacted slightly by the development of oil.Specific measures for the environmental impact of oil development should be issued systematically from the perspective of the government and the public.

石油类污染物对小麦的出苗率、株高、穗长影响较大；石油类污染物对玉米、大豆和棉花种子的发芽率均有影响，其中影响最大的是棉花种子；通过野外调查选择油井附近的苹果树和对照点没有污染的苹果树进行对比分析，发现石油开发对果树的叶片衰老指数、叶片叶绿素含量和苹果的营养成分等影响较小。

Besides the purchase makes merry the new year's goods, each and every family must manufacture "cuts Ma" the grain to fight, namely, in draws has about the colored pattern wooden box to distinguish the roasted barley which Sheng Fangchao the grain of wheat and the crisp oil mix become, above inserts blue Guangzhou and the butter models the system the color flower.

除购置吃喝玩乐的年货外，家家户户都要制作一个名叫&切玛&的五谷斗，即在绘有彩色花纹的木盒左右分别盛放炒麦粒和酥油拌成的糌粑，上面插上青棵穗和酥油塑制的彩花。

The result of fertilizer management of Sutian8 shows: what use the fertilizer of early stage handled, the plant height, ear height, stem thickness, leaf area etc. were better than early stage apparently, did not apply fertilizer to hand. Fertilized in lump sum on early stage, although expression was sent early for strong sprout, had also formed high-yield group, but later stage had the phenomenon of premature senility; Early stage did not be applied fertilizer, even if in late stage mend the fertilizer of equal quality could not also remedy. Corn ear output and quality would not raised unless the fertilizer applied at prophase (45%-60%), metaphase and anaphase had a certain proportion.

苏甜八号不同时期肥料运筹试验结果表明：施用前期肥的处理，无论是在株高、穗高、茎粗、叶面积等植株性状上，还是在果穗、产量性状上均显著优于前期不施肥的处理，前期一次性重施肥，虽表现为壮苗早发，也形成了丰产群体，但后期有早衰现象，前期不施肥，即使中后期补施同等数量的肥料也无法弥补因前期不施肥所造成摘要的影响，只有前、中、后按一定比例且适当提高前期肥的用量(45%一6006)才有利于提高鲜果穗产量和商品品质。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
