The effects of different plant densities on flag leaves chlorophyll content,SOD activity and MDA content after anthesis in stronggluten wheat interplanted in paddyfield were studied.

本试验在江苏淮北地区设计不同密度试验，研究其对稻田套播强筋小麦花后剑叶叶绿素含量、SOD酶活性和MDA含量的影响，结果表明：随花后生育进程推移，叶绿素含量呈下降趋势，且随密度增加，下降幅度增大；花后单茎干物质积累量和单茎籽粒产量亦随密度增加而下降，二者呈极显著负相关；随花后生育进程推移，剑叶SOD酶活性呈单峰曲线变化，可用二次曲线方程模拟，在花后1416 d达峰值，且随密度增加峰值出现时间提前，峰值数值呈先上升再下降的变化特征；随花后生育进程推移，剑叶MDA含量呈上升的变化特征，且随密度增大，数值变大；花后35 d剑叶SOD酶活性与花后单茎干物质积累量和单茎籽粒产量呈极显著正相关，而MDA含量与花后单茎干物质积累量和单茎籽粒产量则呈显著或极显著负相关。

Results in those 30 samples, the styloid process showed with high quality inⅠgroup is 25,in Ⅱ group is 27,about length measurement, as a whole, the difference of the two groups is little.

结果 30例中茎突能清晰完整显示的常规茎突侧位有25例，而用口腔全景机拍摄的茎突有27例，在茎突长度测量方面，从两种摄影方法拍摄的茎突影像上测得的茎突长度无显著的统计学差异。

There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index. There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Main stem undeveloped; fertile stems several, arising from rosette, diffuse or ascending, 15--50(--100) cm, glabrous or puberulent on 1 side, very rarely densely hirsute. Basal leaves with blade linear, 5--15(--30) cm × 6--9 mm, margin ciliate only proximally; cauline leaves shorter, ciliate only on 1 side of sheath mouth, glabrous elsewhere, very rarely densely hirsutulous.

根状茎无。主茎不发达；能育茎数个，基生叶具线形的叶片，5-15(-30)厘米×6-9毫米，只下部的边缘具缘毛；茎生叶短，仅在鞘口部一边具缘毛，在别处无毛，极少浓密具微糙硬毛。

The stalk length, internodal length and stalk weight significantly increased, the number of millable stalks per plot raised extremely significantly, the growth speed accelerated and the yield increased by 23.2%, respectively, of regenerative plants from the seedcanes with HWT, compared with those of RSD-infected seedcanes without HWT, but their qualities in maturity phase were similar.

与未经热水处理种茎再生植株相比，经热水处理的粤糖00-236感病种茎再生植株的茎长、节间长度、一茎重显著增加，有效茎数极显著增多，生长速度加快，蔗茎产量增加23.2%，但成熟期甘蔗品质几乎无差异。

We measured morphological and physiological characteristics of C. asiatica in spring 2004 and 2005 at three levels: ramet population, clonal fragment and leaf. Environmental factors of different microsites were investigated again in September 2006. Important findings At the ramet population level, we observed no effect of habitat (forest edge vs. abandoned grassland slope).

在克隆片段水平，林缘和荒草坡生境显著影响积雪草的根干重、花果干重、一级匍匐茎节间长和总匍匐茎节间长，而不同草本层盖度小生境则显著影响花果干重、根冠比、一级匍匐茎数、二级匍匐茎节间长和总匍匐茎节间长。

To better understand the mechanism of sucrose accumulation, the correlation of sucrose content and sucrose phosphate synthetase、sucrose synthase expression was analyzed by monitoring the expression of SPS in leaves and stems.(1) The results of SPS investigating indicated that the sucrose content, the expression of SPS in leaves and stems were increased along with the growth of sorghum, reached the highest level at grain filling stage, and decreased at dough stage.

1对SPS表达检测结果表明，在高粱的生长发育过程中，茎中蔗糖含量、叶片和茎中SPS蛋白质表达量持续上升，灌浆期达到最高，腊熟期略有下降，它们之间的变化趋势基本一致，甜高粱茎蔗糖含量与叶片SPS蛋白质的表达相关系数为0.895，与茎SPS蛋白质的表达相关系数为0.781；甜高粱和普通高粱相比，其叶片中SPS表达量差别不明显，而甜高粱茎中SPS表达量明显高于普通高粱。

Tartaricum, moreover, it was much more obvious in tissues of F. tartaricum. EST-1 and EST-2 existed in leaf and caudex of F. cymosum 2. EST-3 and EST-5 were found in all the tested leaves and the bands in F. cymosum 1 were clearest. For CAT, only 3 bands were detected in all tissues, CAT-1 appeared in the leaves of three buckwheat and clearer in F. cymosum and F. cymosum 1. CAT-2 was detected in different location in leaves and caudexes. CAT-3 existed in the leaves though it was unclear.

EST-1及EST-2只出现在金荞麦2号茎和叶中，EST-3和EST-5只存在于叶片中，并且在金荞麦1号中的带最强，EST-4存在于茎和叶片，在金荞麦1号最强；CAT只有3条带，其中CAT-1出现在叶片中，在苦荞麦1号及金荞麦1号表达较强；CAT-2出在现在茎和叶片，并且茎，叶位置不同；CAT-3只存在于叶片中，非常微弱。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
