萎蔫的

The role of bioassay method in study of relationship between insect and plant volatile as well as the biological significance of attraction of Pterocarya stenoptera to cotton bollworm were discussed.

讨论了生测方法在研究昆虫与植物气味关系中的作用以及萎蔫的枫杨叶气味引诱棉铃虫的生物学意义。

The results showed that the high hygroscopicity resin has the function of delaying the days of corn wilting, and improving economic properties.

在盆栽玉米上施用一定量的高分子树脂，可延迟玉米出现萎蔫的时间，改善玉米的经济性状。

A two-choice olfactometer was developed to determine the behavioural responses of adult cotton bollworm to plant volatiles.

发展了一种选择性嗅觉仪，用这种嗅觉仪测定了棉铃虫成虫对萎蔫的枫杨叶、新鲜的棉花叶、棉花花蕾、玉米叶及玉米花丝气味的反应。

The attracting activity of the extracts of withered black poplar leaves: Volatiles from withered leaves of black poplar, extracted by steam distillation and dichloromethane, strongly attract adults of Agrotis, ypsilon, Spodoptera exigua and Herculia glaucinalis in the field bioassay, but are less attractive to CBW.

黑杨萎蔫叶片粗提物的诱虫活性采用水蒸汽蒸馏和二氯甲烷萃取，提取黑杨萎蔫叶片的挥发性物质。

After being infected by PWN, the needle of 1-year-old pine seedlings with the lignified stem began to change to be bronzing or brown and wilted, which appeared at the phyllopodium and expanded to leaf apex, then the needles withered and died.

而茎已完全木质化的1年生松幼苗和4～5年生幼树离体枝感染松材线虫后，外部症状表现为发病叶褪绿、变红褐色或褐色且萎蔫，症状首先出现在叶基部，很快向叶尖扩展，至整个针叶枯萎死亡。

A major control is the degree of opening of the stomata.

但是在缺乏水分条件下，蒸腾作用便弊大于利，可能会引起植物的萎蔫。

Judged from the papameters including the relative water content and the wa- ter potential of wilting point.

从正常灌水（田间持水量80％）所测定的萎蔫点相对合水量、萎蔫点水势和总体原初渗透压（ψz0）判断， 4种果树抗旱性的顺序是：杏、桃＞苹果＞葡萄。

The permanent wilting point is reached when the plant has wilted to a point where it will not recover, even if more water is added, because the cells have plasmolyzed.

当植物的萎蔫达到一定程度就不可以再复原，这一极限被称为永久萎蔫点。超过此极限，补充再多水分也不能被吸收，因为已经胞质浓缩已经到达质壁分离的程度。

The field water capacity, wilting coefficient and effective water content have negative correlation with crop water requirement, and the linear negative correlation of field water capacity, effective water content and crop water requirement is above the significant level.

土壤田间持水量、萎蔫系数、有效水含量均与作物需水量呈负相关关系，其中，田间持水量、萎蔫系数与作物需水量的线性负相关均达显著水平以上。

Saturated soil water content, field water capacity and wilting coefficient of all the three parent material purple soil also reduces from top to bottom in the soil profile, but effective water content increases from top to bottom in the soil profile except the layer B of J_(3S). The result of saturated soil water content, field water capacity and wilting coefficient is J_(3P)＞J_(2S)＞J_(3S), and the result of effective water content is J_(2S)＞J_(3P)＞J_(3S).

而有效水含量除遂宁组B层外，在剖面呈自上而下的递增趋势，其中田间持水量、萎蔫系数表现为蓬莱镇组＞沙溪庙组＞遂宁组，有效水含量表现为沙溪庙组＞蓬莱镇组＞遂宁组。

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。
