摘要
为扩大烟草种质资源的范围以及缓解吸烟与健康的矛盾,利用普通烟草品种沙姆逊与药用植物罗勒和紫苏进行科间远缘杂交育种,选育出新型烟草品系香料型罗勒烟和香料型紫苏烟,研究了喷施光合细菌菌液对其农艺性状及品质的影响。光合细菌菌液由Rhodospirillium、Rhodopseudomonas、Rhodobacter、Chromatium和Chlorobium等菌株发酵培养,菌液含菌数达5×109个·mL-1。在苗期和大田以1∶200的比例对烟叶叶面喷施光合细菌菌液,能够促进新型烟草的生长,提高烟叶的产量;对外观质量的改善不显著,但对烟叶内在化学成分的含量及其协调性具有显著的影响,能够同时降低烟碱并增加钾的含量。评吸结果显示,光合细菌处理后的新型烟草香味独特,余味纯净,劲头适中。
In order to extend the range of tobacco germplasm resources and release the contradiction between smoking and smoker's health,the distant hybridization between tobacco and medical plants was expected to incubate the new-type tobacco which included medical ingredients.The new-type tobacco strains such as Zisu and Luole were the hybrids of families between Samsun(a variety of Nicotiana tobacum L.)and medicinal plants Perilla f rutescens(L.)Britt and Ocimum bailicum L.,respectively.The effects of photosynthetic bacteria(PSB)on agronomic properties and quality of new-type tobacco were studied.Photosynthetic bacterial strains including Rhodospirillium,Rhodopseudomonas,Rhodobacter,Chromatium and Chlorobium were cultivated,and the number of bacteria was 5×109 CFU·mL-1.Results show that it can promote the growing and improve the agronomic properties of Zisu and Luole,but the appearance quality is not improved markedly when PSB liquid is sprayed to the tobacco leaves at the ratio of 1∶200 dilution during the seeding stage and field growth phase.Moreover,analysis results indicate that PSB notably impact chemical component contents in leaves,such as total sugar,reducing sugar,nicotine and potassium,and make them more harmonious.Especially,it can decrease the content of nicotine in leaves of Zisu by 40.96 %,while can increase the potassium content by 19.05 %.And the smoking quality of leaves in PBS treatment is much better than those in the untreated control.
