Integrate low temperature and ultra-dry to excogitate better method to prolong seed longevity, at the same time, we found out the optimal method of ultra-dry preservation, screen out to the excellent desiccant with low cost and good effect, validate the method of ultra-dry can use to deal with and conservation even more large numbers of tobacco seed, yet explored seed vigor comedown rule of tobacco seed, that avoid seed vigor loss prematurely.

在此基础上，把超干燥与低温保存有机地结合起来研究，找出了延长烟草种子寿命的更好方法，找出最佳的超干燥保存方法，优选出成本低、效果好的干燥剂，验证了超干燥也可用于更大量烟草种子的处理和保存，初步探明了烟草种子的活力丧失规律，有效预防了种质资源的失传，最大限度地延长种子保存寿命达25年以上。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

High social costs from the perspective of the economics described the unscientific of tobacco consumption, and serious localism of tobacco production and sales areas turn out to be low efficiency, has hampered the development of the tobacco industry, to be the great waste of the community.

高昂的社会成本从经济学的角度说明了烟草消费的不科学性，严重的地方主义产生了烟草生产、销售领域的低效率，制约了烟草行业的发展空间，给社会造成更大的浪费。

After joining WTO, chinese nicotian enterprise must face new more austere competition environment, use why to plant the problem that the person that means answers competitive pattern of future to become business management is badly in need of solving, and use in coordination this one new IT pattern develops electronic business affairs the industry supplies chain or nicotian group will be our country nicotian enterprise is very good answer strategy.

加入WTO以后，中国烟草企业必须面对新的更为严峻的竞争环境，采用何种方式应对未来的竞争格局成为企业管理者急需解决的问题，而采用协同电子商务这一新的信息技术模式发展行业供应链或烟草集团将是我国烟草企业很好的应对策略。

In this paper,the behavioral,physiological, ecological adaption mechanism of H.armigera and H.assulta to their common host plant tobacco were studied comparatively,and the main results were summarized as follows:Electroantennogram response of adult to tobacco volatiles:(1) H.armigera and H.assulta elicited similar EAG responses to the tested 20 tobacco volatiles;both of them elicited significantly more sensitive to green leaf volatiles,aliphatic and aromatic compounds, than to monoterpene,sesquiterpene,heterocyclic compounds under lower concentration; while the similar EAG responses under higher concentration were detected,but most of them were not significantly different with each other.

本文从行为、生理和生态适应三个方面，对棉铃虫和烟夜蛾与烟草间的互作进行了比较研究，主要结果如下：成虫对烟草挥发物的EAG反应：(1)两种夜蛾对测试的20种烟草挥发物均可产生EAG反应；低浓度下对绿叶气味、脂肪族、芳香族化合物的EAG反应显著高于单萜类、倍半萜类和杂环化合物；高浓度下的EAG反应也表现出相似的总体反应趋势，但多数反应值间的差异未达显著水平。

As a result, the green fluorescence emitted from Nicotiana glutinosa was detected, but no green fluorescence was detected from Nicotiana tabacum cv.

研究中同时利用了3个不同的烟草品种，利用同样的方法和操作程序，但是最后根据烟草叶片中绿色荧光的检测结果发现，不同的烟草品种对OsWAK1：：GFP融合蛋白的表达差异很大。

The MSA is a comprehensive accord formed in 1998 with the Attorneys General of 46 states and five territories that has fundamentally changed how tobacco products are marketed, advertised and promoted, according to the company.

据通用烟草公司说，《大和解协议》是烟草公司与美国46个州和5个保留地的首席检察官在1998年达成的一项综合的协定，从根本上改变了烟草产品营销、广告与宣传的方式。

Tobacco tomato spotted wilt disease was found in many provinces.This disease is widely distributed in Yunnan production tobacco area and it causes above 60% losses in some area. The tomato spotted wilt disease is one of the most potentially dangerous disease of tabacco in the world. This paper reviewed the distribution,symptomology, causal agents, pathogenic mechanism, the composition and function of virus genome and epidemiology and management of the tobacco tomato spotted wilt disease.

目前该病在中国许多省均有发生的报道，在云南烟区广泛分布，在局部地区可造成60%以上的严重损失，烟草番茄斑萎病被认为是世界上对烟草最具潜在危险病害之一，较为系统全面的综述了烟草番茄斑萎病的发生与分布，病害症状学，病原物，致病机制，病毒基因组结构和功能以及病害的流行及控制等方面的研究进展。

This paper presents the cam mechanism of the BEJ tobacco packing machine s from Yunnan Tobacco Machinery Factory.

本论文研究课题来源于云南烟草机械厂的BEJ系列烟草包装机械，论文对目前该烟草包装机中凸轮机构的设计、仿真与数据分析的传统方法和现代方法分别做了较为深入的研究。

Self-view, we must study the experience of other countries and discard the dross and select the essence to help China tobacco industry advertising from the historical turning point.

自我看来，必须学习外国的经验，去其糟粕，取其精华，帮助中国烟草行业广告走出历史的转折点，在入世之后带给中国烟草行业以新的面貌，同时抓住新的机遇，为中国烟草行业开辟全新的局面。
