2015年7月,云南省烟草农科院建成国内唯一一座多功能可视化烟草旱棚。近日,2016年第6期美国烟草知名杂志《Tobacco Reporter》以“Digging Deeper (挖得更深)”为题,图文并茂地报道了该旱棚的功能及用途,充分显示我国在烟草根系研究手段上已与国际接轨。
This paper describes the modification of an existing gas chromatographic (GC) method to incorporate simultaneous mass spectrometric (MSD) and flame ionization detection (FID) into the analysis of toba...
In November 2008, the CORESTA Smokeless Tobacco Sub-Group (CSTS) was established by recommendation of the CORESTA Scientific Commission. At the Amelia Island FL CSTS meeting, October 2009, Working...
Zimbabwe Tobacco Association (ZTA) was formed in 1928; among its objectives it promotes and supports research and training to ensure the continued development and expansion of the flue cured tobacco g...
The Tobacco Institute of Southern Africa (“TISA”) is the industry body for the tobacco industry in South Africa and our mandate and reach extends into the region. TISA represents tobacco growers, leaf...
The harmful effects of smoking tobacco are well documented, both for the smokers themselves, and those passively exposed to cigarette smoke (environmental tobacco smoke, also called second-hand smoke)...
In 2010, the CORESTA Smokeless Tobacco Sub-Group conducted a collaborative study that included the four CORESTA Reference Products (CRPs) and five commercial smokeless tobacco products. This st...

对较高精度的烟叶数字图像进行背景去除和分割预处理,计算烟叶颜色各分量(红色、绿色、蓝色、亮度)的计盒维数,绘制各颜色分量的计盒维数变化曲线,进行烟叶颜色系统聚类分析。结果发现不同产地烟叶的颜色各分量计盒维数变化曲线存在较明显差异;采用颜色分形维数作为聚类参数得到了最好的分类结果。这表明颜色分形维数可以作为按颜色分类的特征指标,能更准确地描述图像颜色的分形分布特征。
It was concluded that the AITC oil showed promise findings and may be a good alternative to old fumigant “phosphine”. The others were found efficient on the spray application bioassays but the mixture...
