Effects of glucose modification of activated carbon on its adsorption and desorption performances to β-phenylethanol

2018 Vol. 24 (1): 1-5,13 [Abstract] ( 92 ) HTML (0 KB) PDF (5204 KB) ( 190 ) | Cite this article

Abstract：Glucose modification was proposed to modify activated carbons (ACs) to regulate bonding force between ACs and β-phenylethanol. Effects of modification temperature on ACs pore structure and surface groups, and thus for their performances of adsorption and desorption β-phenylethanol were investigated. Results show that glucose modification have no significant influence on absorbtion profermance of ACs. However, the modification increased acid sites on surface, which probably weakened π-π dispersion force between carbon surface and β-phenylethanol. Because of that, desorption property of modified ACs was probably improved.

Prediction model for flue-cured tobacco leaf mildew based on NIR spectroscopy combined with chemometrics

2018 Vol. 24 (1): 6-13 [Abstract] ( 102 ) HTML (0 KB) PDF (7036 KB) ( 106 ) | Cite this article

Abstract：A near infrared spectroscopy (NIR) prediction model was built for tobacco mildew early warning based on content of ergosterol. Twenty leaf tobacco samples of two grades (B2F and C3F) in 2015 and 2016, from five regions in Yunnan province, were collected as research material. Mildew tests were conducted under artificial conditions (28℃, 80% relative humidity, and 18% of leaf water content). Tobacco leaves were sampled every 3 days, and ergosterol content was determined. Based on principal component analysis (PCA) and Hotelling T2 parameter, a prediction model was established. Early warning of tobacco mildew was compared between model prediction and unaided eye observation. Results indicated that (1) when mildew became macrosopic, ergosterol content of tobacco leaf increased by 4.66-23.38 folds compared with initial value. (2) Among the 20 samples, nine confirmed mildew pre-warning by 3-6 days, and four warned at the same day when mildew was macrosopic, while no mildew was found in the rest seven samples. It was concluded that the model can be used to predict flue-cured tobacco leaf mildew.

2018 Vol. 24 (1): 14-20 [Abstract] ( 110 ) HTML (0 KB) PDF (6443 KB) ( 79 ) | Cite this article

Abstract：In order to investigate the effects of atmospheric deposition on heavy metal content in flue-cured tobacco leaves, different types of tobacco planting areas in Huanghuai region including countryside, roadside and industrial (cement factory) surroundings were chosen as material from June to September in 2015, and Pb isotope was used to trace Pb element in atmospheric deposition, topsoil and tobacco leaves. Results showed that:1) Heavy metals contents in atmospheric deposition of different types of tobacco-planting areas in Huanghuai Plain were different. Contents of As and Pb in industrial surroundings were 7.19 μg·m2·d-1 and 40.10 μg·m2·d-1, respectively, much higher than those in countryside and roadside areas. 2) Pb content in cutter leaves of roadside was higher than that of countryside and industrial surrounding areas. Contents of Cr, As and Pb in upper leaves of industrial surroundings were 0.66 mg·kg-1, 0.29 mg·kg-1 and 2.37 mg·kg-1, respectively, much higher than those in countryside and roadside areas. 3) Contents of Cr, Pb in bottom leaves were highly positively correlated with contents of corresponding heavy metal elements in atmospheric deposition. In upper leaves, the concentration of Cr was highly positively correlated with its concentration in soil, while As content was positively correlated with its concentration in atmospheric deposition and soil. The ratio of 207Pb/206Pb in bottom leaves and upper leaves of countryside, upper leaves of roadside, cutter leaves of industrial surroundings was close to that in atmospheric deposition, while the ratio of 207Pb/206Pb in topsoil showed different characteristics. Therefore, atmospheric deposition is one important source of heavy metals, especially lead in tobacco leaves of Huanghuai tobacco growing areas.

Abstract：Backfilling ratio is a key quality index of reconstituted tobacco cut stem. Current measuring methods were inefficient. The aim of this paper was to establish a rapid method to solve the problem. Chromatic aberration and whiteness difference between treated reconstituted tobacco cut stem and control were measured by colorimeter. A significantly linear correlation was found between color and whiteness difference and backfilling ratio (r>0.99). Based on that, a working model was established and proved to meet the requirement of accuracy and precision.

Preliminary study on hemin-induced resistance to alkali stress of tobacco

2018 Vol. 24 (1): 28-37 [Abstract] ( 80 ) HTML (0 KB) PDF (7683 KB) ( 36 ) | Cite this article

Abstract：This study introduced the influence of hemin in tobacco growth and physiological characteristics under alkali stress and attempted to explore the mechanism through antioxidant system, osmotic adjustment system, ion contents and related gene expression. Results showed that 1 μmol/L hemin and 2 μmol/L hemin could promote growth, and increase fresh weight, root length and relative water content of tobacco under alkali stress. Hemin could reduce malondialdehyde (MDA) content and relative conductivity, and increase superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbic acid reductase (APX) activity and contents of chlorophyll, carotenoid, proline, soluble sugar, soluble protein and improve root activity. Hemin treatment could reduce Na+ accumulation and increase absorption of K+, Ca2+, Mg2+. Real-time relative quantitative PCR results showed that hemin could induce NtPDR1, NtPDR3, NtNAC and NtGSH1 gene expression. The above results indicated that hemin could relieve the damage of tobacco under alkali stress result from combined effects of stimulating antioxidant and osmotic regulation system, strengthening ion transport and adjusting related genes expression.

2018 Vol. 24 (1): 38-44 [Abstract] ( 97 ) HTML (0 KB) PDF (7158 KB) ( 78 ) | Cite this article

Abstract：This paper investigated the regulatory effect of auxin on growth of tobacco root and glandular trichome under nitrogen deficiency stress. Sand culture experiment was designed to study effects of nitrogen deficiency stress on tobacco biomass, nitrogen concentration, leaf and root development, auxin concentration, expression of the family gene NtPINs, and efflux protein of auxin. Results showed that, compared with normal nitrogen supply level (NH4NO3:2.5 mmol/L), the biomass of upper leaves, stems and roots decreased significantly under nitrogen deficiency stress (NH4NO3:0.25 mmol/L). Total nitrogen concentration in shoots decreased by about 30%, and that of roots by about 40.2%. The density of trichome of upper leaves increased by 13.9%, and that of middle and lower leaves decreased by 40% and 31.9% respectively. The content of auxin in upper leaves increased by 26%, while that of middle leaves and root system decreased by 7.1% and 13.1% respectively, and that of lower leaves showed no obvious differences. Results of qRT-PCR showed that the expression of NtPIN1, NtPIN3, NtPIN4 and NtPIN9 genes in tobacco roots under nitrogen deficiency stress was significantly lower than that in the control group (P<0.05). It was concluded that under nitrogen deficiency tress, the growth of auxin in tobacco leaves from upper part of the ground (upper leaves, middle leaves and lower leaves) to the root system is the key factor for the occurrence of glandular trichome and change of root architecture.

2018 Vol. 24 (1): 45-52 [Abstract] ( 86 ) HTML (0 KB) PDF (6510 KB) ( 98 ) | Cite this article

Abstract：In order to clarify differences of glandular trichome secretions between different tobacco genotypes and to screen tobacco varieties with higher trichome secretions, 12 tobacco varieties were identified by gas chromatography-mass spectrometry(GC/MS) in this study. Results showed that cembratrien-diols (CBT-diols) were the main cembranoids among tested varieties, and the content of CBT-diols of flue-cured tobacco was relatively higher. All tested varieties contain α-and β-cembratrien-diols, and the content ratio of α-to β-cembratrien-diols was 1.58~2.32. Five types of sucrose esters were detected, and the tested varieties were divided into two groups according to quality and quantity of sucrose esters:varieties of group one contain higher Ⅰ-Ⅱ and varieties of group two contain higher Ⅲ-V types of sucrose esters. In general, Basma, Beinhart1000-1, Honghuadajinyuan, BX1 and BX2 have more glandular secretions and can be further used in tobacco breeding and extraction of tobacco leaf surfactants.

2018 Vol. 24 (1): 53-59 [Abstract] ( 115 ) HTML (0 KB) PDF (6897 KB) ( 115 ) | Cite this article

Abstract：In order to demonstrate effects of cup-covering transplanting (UCT) on hydrothermal condition and growth of tobacco seedlings, air and soil temperature and humidity in shaftlike cellar, chlorophyll fluorescence parameters and growth of tobacco seedlings were analyzed compared with shaftlike cellar style transplanting mulched film (WST). Results showed that air temperature in shaftlike cellar of UCT was slightly lower, while relative humidity increased. Daily average soil temperature at the bottom of the shaftlike cellar for UCT was between 15.61℃ and 22.20℃, which was decreased by 8.30%~15.71% compared with WST. Average soil water content at the bottom of the shaftlike cellar for UCT and WST was 14.27% and 25.18%, respectively. Infrared temperature imaging analysis showed that there was no significant difference between UCT and WST (P>0.05). However, infrared imaging temperature of ridge furrow for UCT was significantly decreased on a clear day. After taking the cup-covering, the maximum photochemical efficiency and electron transport efficiency of PSⅡ were decreased. Total root length of tobacco seedlings increased by 12.46% and the root diameter decreased by 8.15% for UCT at 4 days after transplanting (DAT). Moreover, the root volume increased by 9.29% at 8 DAT. There were no significant differences in dry matter accumulation of stems and leaves between UCT and WST. Hydrothermal condition in the shaftlike cellar of UCT was suitable for tobacco seedlings. Furthermore, the growth of tobacco seedlings was consistent with that of WST, which can be used as an alternative for WST.

Effect of topping on polyphenols metabolism and key enzymes in tobacco leaves

2018 Vol. 24 (1): 60-67 [Abstract] ( 73 ) HTML (0 KB) PDF (8630 KB) ( 102 ) | Cite this article

Abstract：Effect of topping on polyphenols metabolism, content of polyphenols and relevant key enzyme activities and gene expression using topping treatments on different periods (seedling stage and topping stage) in Honghuadajinyuan were tested by high performance liquid chromatography (HPLC), ultraviolet absorption spectrophotometry and quantitative reverse-transcription polymerase chain reaction (qRT-PCR). Compared with un-topped tobacco plants, topping at the 30th day after transplanting could lead to significant decrease of polyphenols such as chlorogenic acid in leaves, and the activity of PAL, PPO and POD increased, and 4CL activity decreased, while the activity of C4H was not significantly different from control. The expression of PAL1, PAL4 and 4CL2 were up-regulated. Topping at the 85th day after transplanting could significantly improve content of polyphenols in leaves, PAL, C4H, 4CL and POD activity increased, the activity of PPO decreased. The expression of PAL1 was down-regulated, and the expression of 4CL2 was not significantly different from control. Expression levels of PAL2, PAL3, C4H and 4CL1 were up-regulated in two periods. The above results showed that polyphenols biosynthesis in tobacco leaves induced by topping was related to growth period. Polyphenols content after topping was negatively correlated with activity of PPO, and positively correlated with activity of 4CL. At seedling stage the degradation rate of polyphenols in tobacco leaves was stronger than that in synthesis rate, resulting in the decrease of polyphenol content after topping. On the contrary, the synthesis rate of polyphenols in tobacco leaves was stronger than that in degradation rate after flower-bud appeared, which resulted in the increase of polyphenols content after topping.

Effect of harvesting time and curing means on variation of amino acid content in Wanyuan sun-cured tobacco before and after curing

2018 Vol. 24 (1): 68-76 [Abstract] ( 87 ) HTML (0 KB) PDF (6579 KB) ( 61 ) | Cite this article

Abstract：Wanmao 3, a major sun-cured tobacco cultivar in Wanyuan of Sichuan, was used in experiments to investigate effects of different harvesting time and curing means on variation of amino acid content in tobacco leaves before and after curing. Amino acids content in tobacco leaf samples were detected before and after curing. Results showed that the total amount of amino acids in tobacco leaves was 147.9 mg/g before curing. Glutamic acid and aspartic acid content were the most abundant, accounting for 12.5% and 10.7% of the total amino acids, respectively. Total amount of amino acids in tobacco leaves decreased by 29.7% to 104.0 mg/g after curing. Aspartic acid content increased significantly, an increase of 28.9%, accounting for 23.6% of the total amount of amino acids. Glutamic acid and other amino acids decreased significantly. Harvesting time and curing means were proved to have significant effect on amino acids content. Under air-curing conditions, the total amount of amino acids continued to increase with delayed harvesting time, while under sun-cured conditions amino acid content first increased and then decreased. Curing means had significant influence on aspartic acid content. When the maturity of tobacco was low, the content of aspartic acid in sun-cured tobacco leaves was higher than that in air-cured tobacco leaves, while when the maturity was high, the opposite trend was observed.

Abstract：[Objectives] This paper aimed to study effect of biochar types on carbon pool in tobacco-planting soil and on flue-cured tobacco leaves quality.[Methods] We carried out the field experiment in 2013 at Hanzhong of Shanxi. The variety tested was Yunyan97. The experiment had four treatments, T1(conventional fertilizer), T2(T1+ peanut-shell-biochar 600 kg/hm2), T3(T1+rice-husk-biochar 600 kg/hm2), T4(T1+wheat-straw-biochar 600 kg/hm2).[Results] (1) Adding biochar leads to increased organic carbon mineralization rate, dissolved organic carbon content, easy oxidation active organic carbon content, soil total carbon content and soil carbon management index, and also leads to decrease of microbial biomass-carbon content. (2) Adding biochar can reduce total sugar, reducing sugar, K/Cl, and sugar to nicotine ratio of cured-leaves, but increase Nic content, and RS/TS. (3) Adding peanut-shell-biochar can increase easy oxidation active organic carbon and improve soil carbon management index. Adding peanut-shell-biochar can also increase K+ content. (4) Adding wheat-straw-biochar can significantly increase soil total carbon content and Nic content of cured-leaves, exerting negative effect on quality of cured-leaves.[Conclusions] Adding biochar can activate soil carbon library, but different material source of biochar had different effects on tobacco leaf quality.

Application of structural equation model to market evaluation of cigarette products

2018 Vol. 24 (1): 93-99 [Abstract] ( 119 ) HTML (0 KB) PDF (5082 KB) ( 73 ) | Cite this article

Abstract：As domestic cigarette market competition is fierce, manufacturers need scientific and precise evaluation of cigarette product performance in the market to help with decision-making. Such factors as brand, market and product quality need to be considered. Cigarette products taste, packaging index rely on sensory evaluation, which cannot be measured directly. In order to obtain reasonable evaluation and minimize human errors, a structural equation model was built on the basis of large-sample-size market test, Index weights at all levels were set according to software operation results, and quantitative evaluation scores which visualized the impact of various factors on product performance were obtained. Index weights and quantitative scores can help manufacturers to evaluate advantages and disadvantages of products in the market competition objectively, and thus achieve optimization.

Abstract：Based on "key success factors-Key Performance Indicator" (KSF-KPI) theory, a model was established to evaluate self-development ability of tobacco farmers' professional cooperatives. In the model, dependence on tobacco sector, profitability and income of members were taken into account. Empirical analysis in Hunan province showed that self-development ability was moderate, while the dependence was relatively high. Cooperative members get higher income from tobacco planting than non-member growers. But the average return of assets of cooperative was relatively low. The results basically reflected actual situation in Hunan Province, which proved the model's feasibility.
