无性系

It proliferates into clones that produce a continuous supply of a specific antibody .

它能繁殖成一种能不断提供某种抗体的无性系Let's make a deal。

We adopted many forestry techniques, including scarifying, weeding, draining, fertilizing, digging far-between dyke, choosing and breeding eximious clone. We also took measures of excavating aperture and irragating root, directly watering root, daubing remedy, stubbing died trees and sterilizing soil in the aperture.We carried through integrated preventional measures of chemical prevention and biological prevention, by using 200×CuSO4, 70% mancozeb 800×5% Chlorothalonil 800×, and Suillus grevillei. All of the meaures got favorable results. The preventional effect exceeded 72%. The incidence of disease descended from 15.5% in 1998 to 2.8% in 2002.This kind of disease was controlled on the whole.

自1998年开始，经过5年的系统研究，通过松土除草、排水施肥、挖隔离沟，选育优良无性系等林业技术措施；采用挖穴灌根法、直接浇根法、涂药法、死树挖除并对穴内土壤消毒等方法，使用硫酸铜200倍液、70％代森锰锌800倍液、5％百菌清800倍液和厚环乳牛肝菌进行化学防治和生物防治等综合防治技术，均取得了很好的效果，防治效果达72％以上，发病率由1998年的15.5％，下降到2002年的2.8％，使该病基本得到了控制。

I have said several times how great it would be to have a few clones of myself, haha.

我说过多次多麼伟大它是将有几个无性系我自己，哈哈。

Taken from a 9 year old clonal test site were analyzed in order to investigate the genetic variation of wood properties, including air dried wood density and some mechanical properties.

该文利用 9个 9年生三倍体毛白杨无性系木材试样，研究了木材气干密度组成及力学性质的遗传变异规律。

Taken from a 9 year old clonal test site were analyzed in order to investigate the genetic variation of wood properties, including air dried wood density and some mechanical properties.

结果表明，木材气干密度组成及力学性质在无性系间存在显著或极显著差异，并受到中等强度的遗传控制；气干密度的径向和纵向变异与多数研究结果一致；力学性质除抗弯弹性模量和端面硬度外其株内变异趋势也基本符合木材学理论。

Based on the results of information investigation, the paper briefly summarizes the research and application of cell engineering technology in agriculture: Chromosome engineering,protoplast culture,anther culture, cell culture, tissue culture and somatic hybridization. The worldwide development and progress in the application of cell engineering in plant breeding are reviewed.

根据文献研究结果，系统地综述了染色体工程技术、原生质体培养、花药培养、细胞培养与无性系筛选、组织培养与体系胞杂交等细胞工程技术，在国内外农作物育种上开发应用后所取得的新进展、新成果，以及这些新成果的产业化，对促进中国农业生产的发展所起的作用。

F2 and F3 populations of the cross of a rice somaclonal variant Hei-zhen-mi with purple pericarp and its donor parent Basmati 370 with white pericarp were used to study the genetic control of purple pericarp.

选用种皮呈紫黑色的水稻体细胞无性系变异体黑珍米和其种皮呈无色的原始亲本Basmati 370配制组合，同时应用121个DNA探针检测了黑珍米与B asmati370之间的RFLP。

In this research,Young buddings of Clone SCATC 7-33-97 were used as plant materials,adopting to the quadratic general rotary unitized design,with nitrogen,phosphor,potassium,magnesium these four factors with 5 levels(1/2 implement) for fertilizer experiment.

本研究以橡胶幼苗无性系热研7-33-97为试验材料，采用二次回归通用旋转设计安排了氮、磷、钾、镁肥四因素5水平(1/2实施)的肥料试验。

A clonally propagated F_2 population(F_2CP),derived from the rice cross of Qimiaoxiang/91SP068,was used to map rolled leaf QTLs.

以水稻平展叶品种奇妙香和中度卷叶品种91SP068组合的F2无性系群体为定位群体，利用微卫星标记对卷叶基因进行定位。

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。
