“…Numerous studies reported that the nicotine content of tobacco leaves could increase with the increased sun exposure time, rainfall, nitrogen fertilizer application amount, and so on [ 28 ]. In this study, the nicotine level in the tobacco leaves from Xuanen County was lower than the tobacco from Yuxi City, which is consistent with the previous report [ 29 ]. However, no positive correlation was found between nicotine content and sun exposure time in our study.…”

The metabolic profiles of tobacco leaves of two differential Chinese cultivars from different growing regions were analysed using gas chromatography–mass spectrometry (GC–MS). The results of principal component analysis, partial least-squares discriminant analysis and hierarchical cluster analysis showed significant differences in metabolome among three groups, identified 24 differential metabolites, and analysed the metabolic pathway in which the metabolites were involved. Among them, 13 metabolites were associated with geographical regions, including seven organic and fatty acids, four carbohydrates and two secondary metabolites. Four amino acids and two monosaccharides were associated with cultivars and the remaining five metabolites were associated with both. The relationships among the differential metabolites and the distinct characteristics of environment and cultivar were further discussed. In addition, correlation analysis indicated that most of the differential carbohydrates were negatively correlated with the differential amino acids and organic acids. Taken together, this study demonstrates the metabolite differences between two cultivars in different regions, and highlights the effect of environment and cultivar on tobacco leaf metabolism.

“…Flue‐cured tobacco plantations are dominant in south‐west China, and play an important role in the development of agriculture as well as the national economy (Shao et al, ; Sun et al, ). Water and fertilizer are the most vital material resources for the growth and development of flue‐cured tobacco, while their requirements and relationships during tobacco growing have rarely been reported (Tan et al, ; Xia et al, ).…”

Drought has become a severe and frequently happening issue in the Guizhou province of China due to unevenly distributed rainfall and long‐term continuous cropping. Since drought and continuous cropping could be significant in causing the soil environment to deteriorate, measures which are beneficial for improving the growth of crops need are of great concern. In this study, drought conditions and a microbial water‐retention fertilizer (MWF) were applied as influencing factors for the leaf area index (LAI) and photosynthetic characteristics of flue‐cured tobacco. Under different drought conditions, the largest leaf area was obtained in normal conditions combined with 45 g basin−1 MWF (T13), which significantly increased by 32.0% when compared to normal conditions combined with 0 g basin−1 MWF (T1). An index model was further used to validate the above‐mentioned results and the correlation coefficients of LAI among different treatments were precisely simulated (0.981–0.993). The MWF had remarkable effects on tobacco's net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci) and transpiration rate (Tr). Furthermore, normal conditions (550 mm irrigation) combined with MWF (45 g basin−1) proved to be the preferable strategy for improving water use efficiency as well as the tobacco plantation. The results might provide theoretical and practical guidance for the growth of crops in areas with water shortage. © 2019 John Wiley & Sons, Ltd.

“…In the tobacco industry, a large number of tobacco stems, dust, and fines are produced as waste, which occurs in almost one-third of the raw materials [ 1 ]. Papermaking reconstituted tobacco (PRT) is an emerging technology to recycle tobacco wastes, reduce environmental pollution, and save cultivated lands.…”

In the papermaking industry (reconstituted tobacco), a large number of tobacco stems, dust, and fines are discharged in the wastewater. This high salinity wastewater rich in ionic constituents and nicotine is difficult to be degraded by conventional biological treatment and is a serious threat that needs to be overcome. Electrodialysis (ED) has proved a feasible technique to remove the inorganic components in the papermaking wastewater. However, the fouling in ion exchange membranes causes deterioration of membranes, which causes a decrease in the flux and an increase in the electrical resistance of the membranes. In this study, the fouling potential of the membranes was analyzed by comparing the properties of the pristine and fouled ion exchange membranes. The physical and chemical properties of the ion exchange membranes were investigated in terms of electrical resistance, water content, and ion exchange capacity, as well as studied by infrared spectroscopy (IR) spectra, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) analyses. The results indicated that the membrane fouling is caused by two different mechanisms. For the anion exchange membranes, the fouling is mainly caused by the charged organic anions. For the cation exchange membrane, the fouling is caused by minerals such as Ca2+ and Mg2+. These metal ions reacted with OH− ions generated by water dissociation and precipitated on the membrane surface. The chemical cleaning with alkaline and acid could mitigate the fouling potential of the ion exchange membranes.
