Tissue Culture and Rapid Propagation of Actinidia chinensis

It has been briefly studied and reported that Actinidia chinensis , one of economic woody plants, has been bred with the method of plant tissue culture. Aim at the shortage of traditional plant tissue culture ways which ignored the refinement and transplant of test-tube seedling, it strengthen the study to breeding and management of Actinidia chinensis seedlings before they grow up and become mature seedlings. Through our explore, the transplant survive rate of tissue-culture seedlings attain to about 85%.This study is the improvement to traditional breeding seedling means and it is helpful to the rapid propagation of those economic woody plants.     

Tissue Culture and Rapid Propagation of Echinacea Purpurea

It is a burgeoning application field for the biotechnology that to apply the technique of plant tissue culture breed seedling. The authors study the responses of Echinacea purpurea to different proportion plant growth hormone or auxin through adopting the culture tissue technique on the MS. The integrated seedling of Echinacea purpurea can be cultivated by callus, subculture, differentiation and rhizogenesis. The surviving rate of Echinacea purpurea seedling transplant are improved by appropriate sound stimulation appropriate. Study harvest offers the gist for the large-scale breeding seedling and the officinal resource exploitation of Echinacea purpurea in our country, and avoid some traditional handicap in breeding seedling of Echinacea purpurea, such as the difficult of seed collection, low burgeoning rate, and the disadvantage for large-scale propagation.     

Study on DAQ System by Using LabVIEW

Dong village is very valuable for research work because of its special regional and national character and rich cultural implication. In this paper, some information about the location, form and features of Dong village is given. Then, the relationship between the culture and the settlement is analyzed, which provides a clue for understanding Dong village and will be beneficial to creating modern human settlements.     

Enterprise Culture and Enterprise Credit in Enterprise Core Competitive Force

Based on the content of enterprise culture and enterprise credit, it is pointed out that the enterprise culture related to the enterprise core competitive force.In this paper, from the viewpoint of combining theory with practice, the intension, function and mutual relations between them are described and their significance in the market competition as well.The potential things,which the enterprise staffs are seeking for, from its inherent mind and the enterprise theory are the enterprise culture which becomes the enterprise core competitive force in its actual sense.The enterprise credit, as the enterprise culture in its ideological sphere, is an essential factor, which greatly affects the enterprise core competitive force.At last the authors provide some good suggestions on how to cultivate enterprise credit and to build enterprise culture.     

Effect of Western Architectural Culture on the Traditional Dwellings in Meizhou

Under the special social background and source of history, the western architectural culture affected the traditional dwellings in Meizhou from the 19th century till the 20th century. The framework, outline and materials of traditional dwellings were changed in certain extent while the form of plane layout and interior decoration still stood stable maintaining the native characters. This article analyzes the phenomena of incorporation of things with diverse nature.     

小麦花培材料的筛选和利用

花培育种是一条快速有效的育种途径，采用两种培养基对20个小麦组合材料进行花培分析，结果表明：小麦花培愈伤组织诱导培养基K优于C17，绿苗产率是C17的3.5倍多。不同基因型材料花药培养差异较大，筛选出一批不同类型的高培养力基因型材料，为有目的组配杂交组合提供依据，提高花培育种效率。     

大蒜茎尖脱毒技术及组织培养研究

采用山西栽培的５个地方名蒜茎尖离体培养，获得了无病毒蒜种。结果表明，茎尖大小为０．２￣０．５ｍｍ，不定芽增殖培养基以Ｂ５或ＭＳ４，附加１￣２ｍｇ／Ｌ细胞分裂素和０．０１￣０．１ｍｇ／ＬＮＡＡ，效果最佳。根系诱导在原培养基中加入０．２ｍｇ／Ｌ ＮＡＡ，出根率可达９０％以上。成苗后于１２月份移栽到节能日光温室，成活率达９０％以上。经对脱毒苗形态观察和染色体检测，没有发生异常变化。植株生长健壮，遗传性稳     

葡萄组培苗瓶外生根技术研究

采用不同种类和浓度的生长素诱导葡萄组培苗瓶外生根，并观察组培苗在不同处理基质、不同的温度、不同的生理年龄条件下生根的效果。通过优化技术参数，建立了葡萄组培苗瓶接生根的技术优化体系，结果表明，用浓度为0.3mg/L的IBA浸蘸处理的插条，在温度为27~29℃的环境条件下在基质珍珠岩上培养，瓶苗茎段的生根率可达85.5 %，移栽后苗木的成活率达98 %，相对于其他方法有了较大的提高。该技术的建立有助于实现葡萄工厂化育苗技术的商业化扩大。     

半夏小块茎的形态发生及人工种子制作

离体培养中，经过小块茎发生途径从半夏叶柄诱导了完整植株。用实体解剖、连续切片和三维结构重组等方法观察分析得出：小块茎顶端的叶原基由于不对称生长逐渐将顶端分生组织复盖，随后叶原基的尖端和两侧生长延缓，生长中心转移到背轴面中央，结果导致叶原基长帽状结构。不同发育程度的雏叶和叶原基总是相互叠在一起顶端分生组织复盖于下面。小块茎枯端形成芽的同时，在顶芽附近分化根。
