    Effect of storage method and duration on germination of pelleted flue-cured tobacco seed

    AMANKWA G.; MISHRA S.; SHEARER A.D.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Delhi, Ontario, Canada
    The amount of pelleted seed remaining after seeding can be quite substantial in certain cases, requiring proper storage if the seed is to be seeded the subsequent year. This study was conducted to determine the best storage condition that would maintain ...

    Genome-wide identification and functional characterization of senescence-associated genes of the NAC transcription factor family in tobacco

    LI Wei; LI Xiaoxu; CHAO Jiangtao; ZHANG Zenglin; WANG Weifeng; GUO Yongfeng
    Tobacco Research Institute, Chinese Academy of Agricultural Sciences (CAAS), Qingdao, Shandong, P.R. China
    The NAC family is one of the largest families of plant-specific transcription factors. NAC proteins play important regulatory roles in a variety of developmental and stress response processes in plants. Members of the NAC family transcription factors have ...

    Effects of tobacco curing with flower buds in the same bulk-barn on the quality of flue-cured tobacco leaves

    SUN Fushan; ZHOU Ping; WANG Songfeng; ZI Yinyin; ZHENG Furui; GAO Xianhui; ZHANG Ye; LIU Yajun
    Tobacco Research Institute, Chinese Academy of Agricultural Sciences (CAAS), Qingdao, Shandong, P.R. China
    In order to explore new technologies of tobacco curing and flavouring, tobacco leaves were flue-cured with different amounts of fresh tobacco flower buds placed in the curing barn and the results were compared with those of conventional tobacco curing. ...

    An evaluation of hybrid and pure line cultivars of flue-cured tobacco for cured leaf yield and quality

    AMANKWA G.A.; MISHRA S.; SHEARER A.; VAN HOOREN D.L.
    Canadian Tobacco Research Foundation, Tillsonburg ON Canada
    Currently, hybrids account for about 57% of the flue-cured tobacco acreage in Canada, since the first release of a hybrid cultivar in 2006. Grower expectations for hybrids are high in terms of the potential for improved cured-leaf yield and quality which ...
