Four varieties of winter wheat with different return green rates were used to analyze the plasma membrane stability and the factors that affect winter wheat in the frigid region during winter. The removal of reactive oxygen species, the degree of plasma membrane impairment, water composition and content, and the changes in cell viability in the crowns, which contain the growing point, were studied...
To examine the effect of myogenin gene on the differentiation of bovine skeletal muscle satellite cell, we constructed small interfering RNA plasmid vector to obtain myogenin knockdown bovine skeletal muscle cells, then used cell transfection, real time RCR and Western Blot to detect the influence of myogenin to cell differentiation. Results showed that the knockdown of myogenin significantly decreased...
This paper mainly focused on the growth law, model construction and visualization of a soybean root. A pot experiment was conducted in the laboratory to collect root system data and measure soybean root's length, diameter and number by excavating in different periods. On the basis of an in-depth analysis of root structure geometry, we analyzed the collected experimental data with logistic equations,...
The international financial crisis on our economic development resulted in the inevitable impact on Chinese economy. In order to get rid of the impact, the expansion of domestic demand has been a crucial means of steady economic growth in China. However, the farmers over seven million account for a large proportion should be the main consumers in China. On the contrary, the current lack of domestic...
Climate change is one of the most significant environment issues in the whole world today. And it is one of the most complex challenges of the humanities faced in the 21st century. Climate Change is impacted on our global; nobody can avoid the influence of climate change. The local adaptation strategies on climate change are very important to contribute the mitigation and poverty stricken situation,...
Cytochrome P-450, subfamily I, polypeptide 1 (CYP1A1) encodes a member of cytochrome P450 superfamily of enzymes. This protein localizes to the endoplasmic reticulum and its expression is induced by some polycyclic aromatic hydrocarbons (PAHs), some of which are found in cigarette smoke. To understand the core sequence within the 5′ regulatory region of porcine CYP1A1 gene, nine primer pairs were...
Based on agriculture production knowledge and computer technology, this paper applied database, artificial intelligent, management information system, decision support system, network technology and information integration technology to the field of soybean production, and offered decision support to users in imitating the curse during which experts solved the problems, therefore, guided production...
The kinetic mechanism for the preparation of silymarin from milk thistle seeds was studied during the microwave-assisted extraction (MAE) process. The results showed that the transfer rate of silymarin from milk thistle seeds increased with the microwave output power and temperature during MAE processing. The apparent extraction rate constant k (s−1) was 1.2028×10−2, 1.2248×10−2, and 1.2485×10−2,...
Drought stress is one of the major constraints on turf growth and performance in northern China. Based on previous assessments of drought tolerance levels, four varieties of Kentucky bluegrass (Poa pratensis L.) representing different types (‘Baron’, BVMG type; ‘Blackstone’, Cheri type; ‘Kenblue’, Midwest type; and ‘Bluemoon’, Midnight type) were chosen for this study. Grass materials were established...
The effects of Previously Fermented Juice (PFJ) on the fermentative quality and changes in chemical composition during fermentation of rice straw silage were investigated. The results showed that the PFJ and diluted the PFJ (dPFJ) treated silages had significantly (p<0.05) lower pH and ammonia-nitrogen content, while significantly higher lactic acid content compared with treatments. This study...
This paper investigated the effects of cattle grazing on herbage production and its nutrient and soil characteristics over the grazing season. The grazing experiment was conducted on Deyeuxia angustifolia Bog meadow grassland established in 2010 in Sanjiang Plain. Four grazing treatments were light grazing (LG), moderate grazing (MG), heavy grazing (HG), and a non-grazed exclosure (CK) with corresponding...
This paper elaborated dairy consumption status in Heilongjiang Province from seven aspects: dairy total consumption, comparison of dairy consumption between urban and rural, dairy consumption under different income levels, consumption category structure, consumption brand structure, consumption channels and consumer information source. On this basis, factors affecting dairy consumption and trends...
Three varieties were employed as materials to study changes of photosynthetic traits under low-temperature stress. The results showed that Pn, Gs and Tr decreased under low-temperature treatment. Ci decreased under low-temperature treatment 18°C/9°C, and 16°C/7°C, and it decreased in earlier stage after increased under 14°C/5°C. WUE was increased in earlier stage and after stabilized. The order of...
Prolactin (PRL) is a versatile signaling molecule and regulates a variety of physiological processes, including mammary gland growth and differentiation and the synthesis of milk proteins. While PRL is known to be necessary for high levels of milk protein expression, the mechanism by which the synthesis of milk proteins is stimulated at the transcript level is less known. A major modification in the...
The nutrient status and dynamics of three clover (Trifolium spp.) varieties at different growth stages were investigated with the crude protein content as an indicator of nutrient equilibrium. The crude protein, neutral detergent fiber (NDF), phosphorus (P), and calcium (Ca) content followed a decreasing trend at the initial growing stage and increased later. NDF and Ca content peaked in May, while...
Degenerate primers were designed based on the conserved sequences of the Actin gene from other plants. Total RNA was extracted from the leaves of Iris lacteal var.chinensis Fisch.Koidz. Actin gene fragment was obtained by reverse transcription polymerase chain reaction (RT-PCR) and cloned into pMD18-T vector. The positive clone identified by PCR was sequenced. The sequencing result showed that the...
With the social and economic development, there is growing demand in agricultural technique English. But there exist some obstacles in agricultural technique promotion. Some translators haven't paid attention to their needs and education levels of target readers in agricultural promotion that proves to be obscure translation rather than simple farming method. This paper conducted an investigation...
In order to realize automatic and accurate grading of cucumber, the first thing is to make sure the high accuracy and integrity in cucumber shape segmentation. As the core processor of this dissertation, DSP TMS320DM6437 acquired and processed digital image, it solved the common shadowing problem associated with the natural light. Ultimately, the background subtraction was proposed. Compared with...
Arachidonic acid (AA or ARA), an essential ω−6 polyunsaturated fatty acid (PUFA), can be produced by Mortierella isabellina. Mutagenesis on Mortierella isabellina As3.3410 was induced to raise ARA production. The mutant strain of YZ-124 had the highest ARA of 4.72 g • L −1 , which was 5.5 times higher than that of the original strain 3.3410. mRNA expression level of Δ6-desaturase was determined...
A two-step biotechnological process was developed using Bacillus licheniformis S6 to provide a simple and economical procedure which significantly improved feather meal nutrition value. Compared with IFM (initial feather meal) and CFM (commercial feather meal), SFEFM (feather meal gained by solid fermentation and enzymolysis with continuous agitation) had a significant improvement (P<0.05) in vitro...
