Tobacco brown spot disease has been an important leaf disease in tobacco. In tobacco maturation period, this disease causes tobacco brown spot disease seriously, and makes large economic losses. Its main pathogen is Alternaria alterrrata Keisslar.

烟草赤星病是烟草的一类重要叶部病害，其主要病原菌为链格孢属真菌Alternaria alterrrata (Fties Keisslar，在烟草成熟后期危害十分严重，造成重大经济损失。

Hyphal growth rate method was used to determine the inhibitory activities of chitooligosancharide against the pathogenic fungus of tobacco brown spot, Alternaria alternate Keissler, in the laboratory, and tobacco plants were applied with COS and its combinations like COS + Trichoderma + chitin with 5 treatments to control the disease under conditions of pot culture and inoculation in the greenhouse. Activities of 4 defensive enzymes, superoxide dismutase, polyphenol oxidase, peroxidase and chitinase, in tobacco plants were determined systematically at the same time within 10 days after application of COS and inoculation with the pathogenic fungus.

在实验室条件下，采用菌丝生长速率法测定了几丁寡糖对烟草赤星病菌的抑制活性，继而在温室盆栽和人工接种条件下，分别研究了几丁寡糖、几丁寡糖+木霉+几丁质等5种方法处理对烟草赤星病的防治效果，同时分别系统测定了烟草植株施用几丁寡糖及人工接种赤星病菌后10 d内SOD、POD、PPO和几丁质酶等4种防御酶的活性。

The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.

研究结果可作为烤烟与香料烟类型间的杂种鉴定利用的实验与理论依据。4、利用SRAP标记技术，研究和分析了烤烟、晒烟、晾烟、白肋烟、香料烟等不同栽培类型间的基因型差异，初步筛选出了能够在分子水平上反映不同烟草类型差异的特征性标记带：晾烟MD40、Ky17、Burley21、TN90基因型共有的特征带有两对引物组合，分别为SF25*SR2和SF3*SR26；晒烟小牛舌、青梗、小花青和香料烟Sumsun、komotini Basma、Xanthi Basma共有的特征带引物组合为SF20*SR14；NC89、K326、G-28、大白筋和MD40、Ky17、Burley21、TN90共有的特征带引物组合为SF16*SR14，烤烟中大白筋599的特征带引物组合SF22*SR14.5、利用61对SRAP引物组合，研究了普通烟草不同类型间的亲缘关系，将普通烟草类型间8个不同供试材料划分为3类别。I：烤烟类型G-28II：白肋烟类型(MD40、By21、大白筋599III：香料烟类型(Basma、Sumsun、小牛舌、千层塔)。

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。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
