Every treatment combination has 4 replications.(1)The germination indexes of the former are higher than that of the latter; the germination of the former is stimulated by NaCl density of 0.3 %, while that of the later is restrained by all kinds of NaCl density.(2)With increasing of temperature and PEG indesity,the order of germination rate and vigor of Bromus stamineus and Bromus inermis is decreaced.(3)Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), Bromus stamineus has the highest bud rate, fresh weight, seed yield, while treated with 25cm row spacing and 412kermels·m~(-2) plant densities, tillers, plant height, growth rate increased to the top;(4) Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), its growth rate is took second place, while treated with 15cm row spacing and 824kermels·m~(-2) plant densities, it has the highest seed yield

3撒播时，引进种在播种密度为549粒·m~(-2)处理下单位面积出苗率最高，分蘖数最多，鲜重最大，单株最高，种子产量最大；生长速度在播种密度为412粒·m~(-2)处理下生长最快，密度为549粒·m~(-2)处理下稍次之，结合方差分析可以初步确定它在撒播时的播种密度为549粒·m~(-2)；(4)条播时，在行距为25cm、播种密度为412粒·m~(-2)处理下单位面积分蘖数最多，鲜重最大，单株最高，生长速度最快；种子产量在行距为15cm、播种密度为824粒·m~(-2)处理下最大，在行距为25cm、密度412粒·m~(-2)处理下次之；结合方差分析，就3种规格的行距来说，引进美国无芒雀麦条播时的行距为25cm，播种密度为412粒·m~(-2)；就这两种播种方式来说，应该选择撒播。

Result The ordinary broad sense heritability rates of various traits were at extremely significant level, specially, that of bell weight, lint percentage, top stem thickness were more than 50% and that of the ginned cotton output per plant, bells per plant, plant height, stem thickness of cotyledon node were lower. The ordinary narrow sense heritability of the ginned cotton output per plant and bells per plant were 24% and 25% resp. and that of bell weight and lint percentage etc. were lower or zero.

结果］各性状的普通广义遗传率均达极显著水平，特别是铃重、衣分、顶部茎粗的普通广义遗传率达50%以上，单株皮棉产量、单株铃数、株高、子叶节茎粗普通广义遗传率较低，单株皮棉产量和单株铃数的普通狭义遗传力分别为24%和25%，铃重、衣分等性状的普通狭义遗传力较低或为0。

Path analysis showed internodal distance,first lateral branch number and whole-plant leaf weight with a significant positive effect on vindoline content (P.05), with path coefficients of 0.959, 0.716 and 0.431 respectively, which suggests that internodal distance, first lateral branch number and whole-plant leaf weight are the important factors in breeding C.

通径分析结果表明，长春花的主要农艺性状中，节间距、一级侧枝数和全株叶片重对文多灵含量的正影响达到了显著水平(P.05)，通径系数分别为0.959、0.716和。431，说明节间距、一级侧枝数和全株叶片重可以作为高含量文多灵长春花品种选育的重要参考指标。

Vindoline content showed a positive correlation with leaf width, plant height, whole-plant leaf weight, 100-leaf weight, petal diameter and leaf length; the positive correlation was significant for first lateral branch number and stem diameter (P.05) and notable for internodal distance.

本文利用反相高效液相色谱法检测了23种国内外长春花主栽品种的文多灵含量，对文多灵含量与品种的12个主要农艺性状(包括株高、节间距、茎直径、一级侧枝数、叶片长、叶片宽、叶片长宽比、百片叶重、全株叶片重、花瓣直径、种荚长度和种子数/荚)的相关性和通径进行了分析。

GGR can promote the development of cotton roots like rhizogenic powder. It can also help seedling height, the number of lateral roots, root dry weight, boll weight and boll number per plant.

双吉尔象生根粉一样都能促进棉花根系的发育，对增加苗高、侧根数、根干重、铃重、单株结铃数均有一定的促进作用。

The growth of plantlets with the height of 1-2 cm and 3-4 leaves was compared on MS basal medium containing various organic compounds, including banana, carrot, potato, coconut water, and tryptone. The result showed that the growth of oncidium plantlets was the best on medium containing banana, potato and tryptone altogether with respect to their plant height, leave number, root number, root length, fresh weight, and dry weight. The next better media were the control and the Banana medium, followed by the Potato medium.

另外取高约1-2公分，带3-4片叶片的分化小苗，培养於含不同浓度有机添加物（香蕉、胡萝卜、马铃薯、椰子水、及tryptone）的半量MS培养基，以探讨最适合文心兰瓶苗生长的培养基，试验结果显示，在同时含香蕉、马铃薯及tryptone三种成份的培养基生长的小植株不论在株高、叶数、根数、根长、鲜重、及乾重均较其他培养基为佳；不含添加物之1/2MS培养基、及含香蕉的培养基次之，而在含马铃薯之培养基较差。

Result Under different planting densities, all the 5 characters of the branch number of unit area, leaf number, stem weight, leaf weight and hay yield of alfalfa changed to different extents in the same cutting stage and the whole year, and there was significant difference between some density treatments.

结果］在不同栽植密度下，紫花苜蓿单位面积分枝数、叶片数、茎重、叶重和干草产量5个性状在同一刈割时期及全年度各有不同程度的变化，且在某些密度处理间存在显著差异。

DT_REL This element is similar to DT_RELA, except its table has implicit addends, such as Elf32_Rel for the 32-bit file class.

DT_REL 类型的数组项类似于DT_RELA类型的数组项(例如：。rel.got section 首地址)，只是Rel类型重定位表中的表项会有一个隐含的加数，比如32-bit类型的文件具有的Elf32_Rel数据结构的重定位表项。
