农杆菌介导的抗寒基因转化羽衣甘蓝的初步研究

作者： 张文玲   来源： 西南大学 年份： 2010 文献类型 ： 学位论文 关键词： 抗寒转录调控基因TCF   羽衣甘蓝   甜菜碱合成基因BADH   转基因植株  

描述： siea. Low temperature is the key factor that limits the growth, colour and appreciatability in winter in the northern of China. Introducing foreign gene into kale through genetic engineering may create novel variety with cold tolerance. In this study, BADH(encoding betaine aldehyde dehydrogenase) and TCH(encoding transcription regulation factors) were used to be transformed into kale with Agrobacterium-mediated transformation.

全文：长期霜冻下保持良好的观赏性。植物的抗寒性是多基因控制的性状,以传统育种手段改良有一定的困难,利用转基因技术将抗寒基因导入栽培品种可能成为提高植物抗寒性的一种比较快速有效的手段。本实验以提高羽衣甘蓝抗冻

中国古代农家文化研究

作者： 熊帝兵   来源： 南京农业大学 年份： 2010 文献类型 ： 学位论文 关键词： 农家   民生   农业史   传统文化  

描述： od of Warring States (475-221 B.C.), attracting scholars' attention and becoming one of important schools then. After Qin Dynasty, scholars determining to study agriculture carried forward good traditions of Non自is in the Period of Warring States, enriched researching contents and fields, and enabled Non自is to develop in depth. In finial, those determining to study agriculture formed a group with researching agriculture as its distinguishing feature. What the group researched included agricultural ideologies, techniques of farming and cropping, methods of operation and management, measures of fighting and preventing agricultural calamities. The whole group showed its own styles in valuing agriculture and concerning people's livelihood. And those agricultural ideologies, science and technology, methods and spirits composed Nongjia's culture, the cream of which can afford us lessons to solve today's new problems.
