The results showed that allelochemicals of all 10 kinds of donor species have allelopathy on seed germination of Eupatorium adenophorum, and allelopathy increased with the enhancing of concentration.

结果表明：10种供体植物的化感物质对紫茎泽兰种子萌发均存在化感作用，并且随着浓度的升高，化感作用逐步增强，紫茎泽兰种子发芽速度指数比发芽率更为敏感。

Ratio of the external leaf surface to its volume was smaller in psammophytes than in mesophytes.

轴器官中普遍具有发达的机械组织，一些植物形成异常结构；根的周皮发达；茎中基本组织／半径比率较大；部分植物形成同化枝，有的茎、叶中存在粘液细胞或结晶。

The extraction of a root of a quantity.

具有明显的、匍匐而粗糙的茎或根状茎的各种秋海棠属植物。

The plant with good growth is in big lotus below can wear unripe circuit small lotus, in addition annual spring the red that end still can take out similar bracketplant from phyllome bottom walks along a bine, front walking along a bine is long have lotus shape flocculus clump.

发育良好的植株在大莲座下面会着生一圈小莲座，此外每年的春末还会从叶丛下部抽出类似吊兰的红色走茎，走茎前端长有莲座状小叶丛。

Stems slender, branched, rhizomatous, repent; internodes at first elongate and apically floating, later erect, foliate, and shortened. Leaves dimorphic.

茎纤细，分支，有根状茎，匍匐；节间在早期时伸长并且顶部漂浮，后期的直立，具叶，并且缩短。

The pangola grass with different length was throwed by the free body falling method and the passing time was measured using two infrared ray sensors. The calculative terminal velocity V was calculated through the time and distance. The exeperimental terminal velocity V of grass with different length was measured by the floating method.

本研究之目的乃是以盘古拉牧草为研究对象，改变不同长度的牧草茎，首先以自由落体法，利用红外线感测器量测出时间，藉由时间与距离之关系，代入公式得到计算终端速度；其次以浮力法，量测出不同长度的牧草茎之实验终端速度。

The growth characters, the activities of antioxidant enzymes, including superoxide dismutase, catalase and guaiacol peroxidase, and peroxidase isozyme of the were measured.

测定了不同辐照剂量下新生根状茎的生长，研究了辐照原初根状茎愈创木酚过氧化物酶、过氧化氢酶和超氧化物歧化酶等抗氧化酶活性以及过氧化物酶同工酶谱的影响。

The results showed:(1) the activity concentration of 95Zr in water reduced quickly for subsidence, soil absorption, crucian intake, hornwort's absorption and adsorption.

结果表明：当952：经模拟降雨引入系统后，小麦不仅从根系而且还从茎叶吸收错，952：在小麦中的比活度，以茎叶和颖壳中最高，根部次之，籽粒中最低，仅稍高于本底水平。

Under field continuous drought stress, growth rate, branches of stolon, leaf lengthobviously declined, nevertheless, leaf water content increased and MDA content decreasedsignificantly during field water deficit. SOD activity of the four turf grasses increased at thebeginning of water deficit and then decreased with drought stress. POD activity ofAugustinegrass increased rapidly and then kept stable with water deficit, however, PODactivity of Centipedegrass changed indistinctively.

田间持续干旱下，随干旱时间的延长，钝叶草和假俭草匍匐主茎的生长速率、主茎分枝数以及叶片长度显著(P＜0.05)下降；叶片含水量呈上升趋势；叶片MDA含量呈下降趋势(P＜0.05)；叶片SOD活性总体上呈先上升后下降趋势，但德阳假俭草和宫崎钝叶草峰值出现较早；钝叶草叶片POD活性先上升(P＜0.05)后趋于稳定，而假俭草叶片POD活性变化不显著；四个草坪草叶片CAT活性先下降(P＜0.05)后趋于稳定。

The results showed that there were intraspecific differences in plant height and stem diameter of tolerant clones, and plant height and stem diameter of sensitive clones decreased significantly.

结果表明：(1)割手密耐性无性系株高和茎径对UV-B辐射响应具有明显的差异；敏感无性系的株高和茎径显著或极显著的下降。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
