Organo-petrographic and geochemical characteristics of Gurha lignite deposits,Rajasthan,India:Insights into the palaeovegetation,palaeoenvironment and hydrocarbon source rock potential

Open Journal of Clinical Diagnostics（临床诊断学期刊） 2012年第3期 45-47页

A polymerase chain reaction was performed using re-ported primers for detection of Canine Parvo virus (CPV) in the stool sample obtained from repository. The PCR primers were specific to VP1/VP2 gene of CPV. Sensi-tivity assay of PCR detection was performed by making dilutions of CPV positive DNA extracted from fecal sample, carrying out PCR for each dilution and visualiz-ing amplicons in ethidium bromide stained agarose gel under UV radiation. Study was valuable in determining the efficiency of PCR. The sensitivity of PCR in present study was determined to be equivalent to detection of .00 2pg/µl of CPV DNA. The study was conducted to analyze the variation, sensitivity and repeatability.

本试验在温室中进行,研究了与S配合施用时不同Zn源及其施用水平对P的吸收利用的影响。施S采用K_2SO_4,分0、40、80和120ppm四个施用水平。施Zn采用ZnCl_2、Zn-EDTA和Zn-Rayplex,分0、5和10ppmZn三个施用水平。播种后45天和110天采样测... 详细信息

本试验在温室中进行,研究了与S配合施用时不同Zn源及其施用水平对P的吸收利用的影响。施S采用K_2SO_4,分0、40、80和120ppm四个施用水平。施Zn采用ZnCl_2、Zn-EDTA和Zn-Rayplex,分0、5和10ppmZn三个施用水平。播种后45天和110天采样测定结果表明,施S对大豆植株各个部分吸收P具有协合作用,而施Zn则具有拮抗作用。播种后110天的大豆植株各个部分的P含量顺序为:籽粒>叶>豆荚>茎。施40和80ppmS和5ppmZn的处理,P的吸收增加。大豆植株总P量的50%左右是播种后45天内吸收的。

将玉米品种 partap 分别种植于低、高密度环境条件下,对其多穗性进行四轮全同胞选择。采用鉴定试验和选育圃交错播种的方法,两年内完成了上述四轮。每轮单株穗数的线性反应均显著,且低密度选择条件下的线性反应(0.06穗=5.5％)高于高密度的(0.04穗=3.6％)。每轮籽粒产量的相关增益显著,为4.5％。同时还观察到其它几个性状也存在明显的相关反应。多穗性选择可用于高产、早熟及矮秆基因型的选育。
