2017 Vol. 23 (6): 22-30 [Abstract] ( 18 ) HTML (0 KB)  PDF (1579 KB)  ( 26 ) | Cite this article
Abstract:The aim of this work is to establish objective methods to quantitatively analyze e-cigarettes' sweetness. Sixty samples of e-liquid were collected and measured by electronic tongue. Based on correlation analysis of electronic tongue data and artificial sensory data, three sweetness evaluation models were established by partial least squares, artificial neural network and support vector machine. Comparison results indicated that the support vector machine model was the most reliable for predicting sweetness of unknown e-cigarette samples. The correlation coefficient of the model was 0.96 with average relative error of predicted results of 7.30% and root mean square error of predicted results of 0.61. It was concluded that the evaluation model based on the combination of electronic tongue and the support vector machine can achieve reliable prediction of unknown e-cigarettes' sweetness.

Abstract:Objective:In order to research gene expressional omics features of drought resistance of flue-cured tobacco line LY1306 from the perspective of physiological and gene transcription, physiological changes and differences in gene transcriptional expression of LY1306 under simulated drought stress were studied. Methods:The experiment adopts 15%PEG-6000 treatment. Samples were taken from fresh leaves treated for 0h, 16h, and 24h, respectively. Superoxide dismutase, peroxidase, catalase activities and malondialdehyde, proline content of LY1306 leaves were measured. Transcriptome sequencing and GO/KEGG analysis were performed. Results:The activity of peroxidase and superoxide dismutase and content of proline of LY1306 increased rapidly under simulated drought stress of 15%PEG. GO analysis showed that some biological processes like response to salt stress and response to gibberellin, and functional genes like transcription factor activity and perinuclear region of cytoplasm were up-regulated in 16h and 24h samples. KEGG pathway analysis showed that plant hormone signal transduction and antigen processing and presentation pathways were up-regulated both in 16h and 24h samples. Conclusion:Peroxidase and superoxide dismutase were major kinases in flue-cured tobacco line LY1306 under 15%PEG simulated drought stress. Proline accumulation plays a positive role in drought resistance. Gibberellin and other plant hormone signaling pathways and varieties of drought related biological processes and metabolic pathways are up-regulated at gene expression level. This molecular mechanism is of omportance in drought resistance and adaptability of flue-cured tobacco line LY1306.

Study on potassium nutrient characteristics of flue-cured tobacco of different genotypes
2017 Vol. 23 (6): 45-52 [Abstract] ( 127 ) HTML (0 KB)  PDF (987 KB)  ( 35 ) | Cite this article
Abstract:Tobacco (Nicotiana tabacum L.) has a relatively high requirement for potassium(K). In order to study K nutrient characteristics of flue-cured tobacco in depth, characteristics of mineral K activation, absorption, transport and accumulation of different flue-cured tobacco genotypes were studied under normal potassium supply(K+) and non-potassium supply(K-) conditions. Results showed that, the efficiency of K absorption, K responsivity and K content of high K genotypes were higher than those in low K genotypes. Absorbing ability of root, potassium content and dry matter accumulation of high K genotypes were significantly reduced under K-condition. Low K tolerance ability of high K genotypes was lower than that of low K genotypes. High K genotypes would increase activation of mineral K in growth medium to meet their own needs by increasing root volume and root-shoot ratio under K-condition, but the K content of plant was significantly reduced because the lowest K absorption concentration was higher. High K genotypes is sensitive to K, ability of absorption, transport and accumulation of K and the utilization ratio of K fertilizer are high, but low K tolerance ability is low, which has a guiding significance for high K flue-cured tobacco variety breeding and fertilization.

Abstract:Estimating ecosystem evapotranspiration (ET) using model simulation is of great significance to study regionally spatiotemporal variation of water resources and to evaluate effects of climate change on water management. Based on MODIS-ET model, ecosystem ET in Panzhihua-Xichang (Pan-xi) tobacco planting area was simulated by using remote sensing data and meteorological data from January to October in 2016. The model was parameterized and validated by field flux observation data. Results showed that the ET values calculated by MODIS-ET model with defaulted parameters were about 12.8% lower than observation values. The efficiency coefficient was 0.767, and the average error in early growth period (DOY 105~161) was the highest. After parameterization on the basis of field observation data, the dynamic curve of ET was consistent with measured dynamic curve. The slope of linear regression was 0.997, and the efficiency coefficient was 0.808. These results proved that MODIS-ET model has efficient applicability after parameterization in the study area. The study could provide an applicable ET dataset to support study on water and heat balance in Pan-xi tobacco planting area.

Abstract:[Objectives]This paper aimed to study effects of biochar on soil biological characteristics and soil respiration rate of Cd contaminated soil.[Methods]Experiment was carried out in 2016 by means of pot plants (25kg soil per pot). The added exogenous Cd concentrations were 0mg/kg (G0), 30mg/kg (G1), 60 mg/kg (G2) and the biochar concentrations were 0g/kg (T0), 10g/kg (T1), 20g/kg (T2) respectively. A total of nine treatments were used for the two-factor test, which were G0T0, G0T1, G0T2, G1T0, G1T1, G1T2, G2T0, G2T1, G2T2. Soil microorganisms and soil microbial biomass (carbon, nitrogen), soil enzyme activity and soil respiration rate were measured in different periods. Results showed that soil urease activity, number of soil bacteria and actinomycetes and soil microbial biomass carbon and microbial biomass nitrogen and soil respiration rate increased significantly along with the application of biochar, and all reached higher level 55d after transplanting. Soil respiration rate increased with growth period, and soil respiration rate increased significantly with the increase of biochar application in heavily Cd contaminated soil.[Conclusions]Application of biochar can significantly improve biological characteristics of Cd contaminated soil and improve soil respiration rate, so as to improve quality of Cd contaminated soil.

Effect of composition differences of alkaloid in burley tobacco leaves on TSNAs formation before and after high temperature storage
2017 Vol. 23 (6): 69-76 [Abstract] ( 14 ) HTML (0 KB)  PDF (1340 KB)  ( 20 ) | Cite this article
Abstract:Field experiment was set up to select tobacco samples with different alkaloid composition by choosing different nicotine conversion strains of TN86 under the same field management and air-curing conditions. The selected samples were stored in temperature/humidity-controlled chamber at 45℃ for 12 d to explore the source of TSNAs accumulation during high temperature storage and its relationship with alkaloid content. Results showed that significant variation of individual alkaloids existed among 90 tobacco plants with greatest differences being observed for nicotine and nornicotine contents. With approximately same levels of total alkaloids, NO3-N and NO2-N contents, TSNAs contents at 45℃ for 12 d were significantly higher than those before storage. The increase of NNN and NNK contents during storage was significantly positively correlated with their precursors, nicotine and nornicotine, respectively. With the increase of nornicotine content, the net increase of NNN from nornicotine nitrosation during storage was greater than the net decrease of NNK from nicotine nitrosation, leading to the net increase of total TSNAs content. Results of correlation and stepwise regression analysis showed that the increased percentage of nornicotine caused by nicotine conversion, was the main factor influencing TSNAs formation during high temperature storage. It could be concluded that at same levels of total alkaloid, NO3-N and NO2-N content of tobacco leaves, the difference in alkaloid composition has significant impact on TSNAs formation and accumulation during leaf storage.

2017 Vol. 23 (6): 77-87,93 [Abstract] ( 18 ) HTML (0 KB)  PDF (1876 KB)  ( 18 ) | Cite this article
Abstract:Samples of two flue-cured tobaccos, two burley tobaccos and one sun-cured tobacco were collected regularly to investigate changes of TSNAs, alkaloid and nitrate content during storage under natural conditions for 5 years. Research showed that NNN, NNK, NAB, NAT and total TSNAs contents of 5 tobaccos increased as storage time increased and the change fitted in quadratic curve model. TSNAs content in burley tobacco was the highest, followed by sun-cured tobacco and flue-cured tobacco and the change was most obvious. TSNAs content was significantly increased in Sichuan burley tobacco, compared with that in Yunnan burley tobacco. It showed non-increase after storage and that the difference of flue-cured tobacco in two areas were not obvious. Alkaloid and nitrate contents decreased during storage. Nicotine content of sun-cured tobacco and the nornicotine content of burley tobacco was the highest and decreased significantly. Nitrate contents of different types of tobacco were extremely variable, average content of burley tobacco was 3076.50μg/g, 109.68 times higher than that of flue-cured tobacco. TSNAs content of tobacco leaves during storage was correlated with alkaloid and nitrate, and nitrate which was more closely related to TSNAs content after storage than that before storage was more closely associated with TSNAs formation.

Abstract:In order to understand the status of Nicotiana tabacum germplasm highly resistant to tobacco mosaic virus (TMV), to provide information for highly resistant parents selection in tobacco breeding, tobacco germplasm with N gene were selected by using N gene-specific molecular markers, and their N introgression segment lengths were tested by using N introgression segment specific molecular markers. Results showed that 63 tested tobacco germplasm could be divided into three main categories, Coker176 type:GL3.50 and GL4.06 marker negative, TN4.39, TN5.226, TN5.51 marker positive; Samsun NN type:GL3.50, GL4.06, TN4.39, TN5.226 marker positive, TN5.51 marker negative; Xanthi NC type:GL3.50, GL4.06, TN4.39, TN5.226, TN5.51 marker positive. The N introgression segment length of 402 and other 51 germplasm belonged to Coker176 type. The N introgression segment length of Ky160 and other 1 germplasm belonged to Samsun NN type. The N introgression segment length of Ky52 and other 9 germplasms belonged to Xanthi NC type. Germplasm with short N introgression segment may have less linkage drag, and are of greater breeding potential. The N introgression segment lengths of TMV highly resistant germplasm were evaluated in this paper, which could provide information for selecting highly resistant parents in variety development.
