野生二粒小麦耐盐鉴定的结果表明：供试野生二粒小麦的耐盐性总体上不如普通小麦。

A set of spelt monosomic lines as female parent were respectively crossed with wheat new variety SM96 and new line SM20005 to determine the chromosomal location of the gene conferring resistance to powdery mildew in both. Seeding of parents, F〓 and F〓 from monosomic F〓 were inoculated with race no. 15 of Blumeria graminis f. sp. tritici. Analysis of obtained data revealed that one major dominant resistant gene originating from wild Emmer in the variety SM96 and the line SM20005 was located on chromosome 4A.

为确定小麦新品种沈免96和新品系沈免20005含有的抗白粉病基因所在染色体，以一套斯卑尔脱单体系为母本分别与沈免96和沈免20005杂交，将亲本、F〓、单体F〓植株的F〓代群体在苗期用小麦白粉菌15号小种的单孢菌系接种鉴定，单体分析结果表明，沈免96及沈免20005所含源于野生二粒小麦的抗小麦白粉菌15号小种的1个显性主效基因位于4A染色体上。

Sp. tritici of the F1 plants were tested at the seedling and adult stages. The results indicated that dominant and semi-dominant genes were responsible for powdery mildew resistance at the seedling stage, while dominant, semi-dominant and recessive genes were found controlling the powdery mildew resistance at the adult plants. After testing the Pm30 linked SSR marker Xgwml59 on the 40 F1 hybrids between wild emmer and common wheat, it was found that the Pm30 linked Xgwm159 loci could be detected at 8 F1 hybrids, indicating the 8 wild emmers might also carry the Pm30 gene.

对F_1植株的苗期和成株期抗性鉴定结果表明，在这些野生二粒小麦材料中，苗期抗性由显性和部分显性基因控制，而成株期抗性则由显性、部分显性和隐性基因控制。40份F_1代材料经Pm30基因连锁的SSR标记Xgwm159的测定，有8份材料可能含有Pm30基因。

Bone age is very significant for selecting talents of art and sports, evaluating the health and growth of children, diagnosing endocrinopathy, evaluating the treatment effect and identifying the actual age in medical jurisprudence.

骨龄测定在文艺，体育人才选拔，儿童健康及发育状况评价，小儿身高异常及内分泌疾病的诊断，药物和疗效评估以及法医学鉴定等方面有重要意义。

A PCR product was amplified using RT-PCR method from total RNA from the abdomens of R strain using the degerated primer. The PCR product was purificated and cloned. The plasmid is pBluescript Ⅱ KS. Recombined plasmid DNA was identified by endoenzyme. The results indicated there were different P450 genes in the PCR product.

运用这对简并引物首次从德国小蠊抗拟除虫菊酯的品系R中扩增出的特异性的DNA片段，经纯化、连接和转化，重组至pBS质粒，筛选阳性克隆，提取重组质粒的DNA，并经初步的酶切鉴定，发现存在着不同的CYP4基因。

Methods Eukaryotic expression plasmid pCMVCD was constructed , and identified by re2 striction endoenzyme digestion. CD gene was transfected into NSCs from new2born Wistar rats using Lipofec2tamine2000. Positive clones (named NSCs/ CD cells) were screened by G418 presence. 52Fluorocytosine (52FC) ad2ministration of different concentrations were incubated with NSCs/ CD cells. NSCs/ CD cells viability ratios were mea2 sured by MTT assay.

通过构建真核表达质粒pCMVCD ，限制性内切酶消化鉴定后，采用Lipofectamine 2000 脂质体介导法转染新生大鼠室管膜下区神经干细胞(Neural stemcells ， NSCs)，G418 筛选阳性克隆，加入不同浓度的52氟胞嘧啶(52Flourocytosine ， 52FC)，MTT比色法测定NSCs的生存率。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
