1.The results of comparison experiments and demonstrations conducted in multiple locations in2001-2003showed that HKJ1#could obviously improve tobacco leaf structure and increase the percentage of high class leaf,the percentage of orange leaf and the average price of raw tobacco by12.51,22.03and1.19yuan/kg respec-tively.
2001～2003年多地联合对比试验和示范表明,使用烟叶烘烤剂1号,可较明显地改善烟叶等级结构,上等烟平均比对照提高12.51个百分点,桔黄烟平均增加22.03个百分点,原烟均价平均提高1.19元/kg。
2.27 Bacillus thuringiensis strains containing cryⅠand cryⅤ toxin gene were isolated from tobacco leaf, soil and stored tobacco leaf dust samples. They were indentified belonging to sotto,tochigiensis, israelensis, shandongiensis, kyushuensis, Dakota, subtoxicus, darmstadiensis auzawai,9 Bt subspecies by the method of physiological and biochemical experiments. And the bioassay of toxicity were determined to Lasioderma serricorne (F.)
对从烟叶、土壤、烟叶仓库粉尘等样品分离出的27株含cryⅠ或cryⅤ毒素蛋白基因Bt菌株进行分类鉴定,分别属于猝倒亚种、励木亚种、以色利亚种、山东亚种、九州亚种、达可他亚种、杀虫亚种、达姆斯塔特亚种、鲇泽亚种等9个亚种。
3.Results indicated that suitable IAA density(20 mg/kg) increased NR activity of tobacco leaf,slowed down the Inv activity dropping,enhanced the root system vigor,increased tobacco potassium content of all flue-cured tobacco leaves,and at the same time reduced nicotine content.
结果表明:打顶后喷施适宜浓度的IAA(20 mg/kg)可以增加烟叶NR活性,减缓烟叶Inv活性下降程度,有利于提高根系活力,增加烟叶钾含量,同时具有降低烟碱含量的作用。
4.The total DNA of fluecured tobacco, CV87, with resistance to alternaria alternata, was introduced into susceptible fluecured tobacco, NC89, through pollen tube pathway. Their first generation (D_1) was analyzed in field growth traits, resistance, and quality of tobacco leaf.
采用花粉管通道技术将抗赤星病烤烟CV87的总DNA导入感病烤烟NC89，对其D_1代植株进行了田间生长性状、抗病性和烟叶品质的检测。
5.Contrasting with lower part of tobacco leaf and middle part of tobacco leafs, upper part Flue-cured tobacco leafs during its latter stage have more contents about β-carotene、neoxanthin、violaxanthin、lutein and xanthophylls,and β-carotene has 68.04μg/g as the most.
与下部叶片、中部叶片相比,上部叶片发育后期β胡萝卜素、新黄质、紫黄质、叶黄质、叶黄素含量均较高,其中β胡萝卜素含量最高,为68.04μg/g。
6.In order to provide the references for proper selection of tobacco leaf in low tar cigarette design, the determination and comparison of the static burning rate of several Chinese and Zimbabwean flue-cured tobacco leaves were conducted.
为了解各种单料烟的燃烧性能 ,为低焦油卷烟叶组配方设计中合理选用烟叶提供参考依据 ,对国内一些主要产区的烤烟以及津巴布韦烤烟的自由燃烧速度进行了测试和对比分析。
7.CIE1976-L*a*b* was used as external color system for tobacco leaf color quantification description . The color indexes of 41 samples were measured and analyzed from different point of view. Pointed out the color characters of each location .
本研究确定CIE1976-L~*a~*b~*作为烟叶颜色量化表达的表色系，测量了41份样品的颜色指标，从不同角度的分析，揭示了各个产地的颜色性状、比较了色度差异、表明了人为定性定色不准确性，同时，分析了各项颜色指标与烟叶内在的化学成分和感官质量间的相关分析。
8.The content of N,Mg,F e and Zn of tobacco leaf was closed related to AM fungal species and P applied levels.
烟叶N、Mg、Fe、Zn含量因菌种和施P量不同而变化 .
9.The tobacco leaf covering a cigar.
卷雪茄的烟草叶
10.Injurious insect pests in storehouse of tobacco leaf were found to have 8 species,8 families,2 orders in one class.
查到烟库害虫1个纲2个目8科8种。
