盐胁迫对柽柳和白刺光合日变化的影响   总被引:2,自引:0,他引:2  
为了筛选耐盐植物以便在盐碱地推广种植,以2 年生的白刺和柽柳为试验材料,设定NaCl 溶液浓度梯度为0(CK)、100(Y1)、200(Y2)、400(Y3)、600(Y4) mmol/L,研究盐胁迫下对白刺和柽柳的光合日变化的影响。结果表明:(1)柽柳与白刺在盐胁迫下的日平均光合速率(Pn)变化趋势与非盐胁迫情况下基本相同;(2)白剌的光合能力强于柽柳;(3)随着盐浓度的增加,白刺的日平均光合速率(Pn)和羧化效率(CE)的降低速率比柽柳快;柽柳在盐胁迫下的水分利用效率(WUE)比非盐胁迫下高,但白刺仅在Y1和Y2 处理下较对照高,并且柽柳的水分利用率始终大于白刺;(4)柽柳从Y3 处理开始出现盐胁迫造成的非气孔限制,白刺从Y1 处理就开始出现盐胁迫造成的非气孔限制。综上所述,说明柽柳的耐盐能力强于白刺,更适合在研究区条件下推广种植。  相似文献

Studies were given to the induction and growth of callus of Aloe vera L.var.chinensis(Haw.) Berg when the young stem was applied as explant.MS was taken as basic medium,added with various concentrations of auxins(IAA,IBA,NAA and 2,4-D),cytokinins(6-BA,KT and Zeatin) and the different combinations of these plant growth regulators.Results showed that the callus is barely induced by cytokinin alone,and the callus induction rates have significant difference when different concentrations of auxin and different combinations of auxin with cytokinin are used on the MS medium.In order to inhibit callus browning during culturing,various concentrations of vitamin C or active carbon are added into four combinations of auxin and cytokinin respectively,which can induce callus most effectively.The result showsd that vitamin C can alleviate callus browning more effectively than the active carbon.The most efficient medium for induction and growth of callus of Aloe vera L.var.chinensis(Haw.) Berg was MS+2.0 mg/L 6-BA+0.5 mg/L 2,4-D+10 mg/ L vitamin C,with which the callus induction rate can reach to 91.4% and callus grow vigorously.  相似文献

The uniaxial hot compression test with Gleeble-1500D thermal simulator is performed on AZ31-0.5Sr-1.5Y alloy in the temperature range of 250-450 ℃ and stain rates of 0.01-1 s -1 with the maximum deformation degree of 0.85. The hot deformation behavior and hot workability of the alloy are studied. The constitutive equation and processing map of the alloy are established and studied by optical microstructure observation. The results show that the steady flow stress of AZ31-0.5Sr-1.5Y deforms at elevated temperatures can be described by the hyperbolic sine constitutive equation, and the activation energy is about 186.83 kJ/mol. After analyzing the hot processing map, at the true strain of 0.6, there is one unsafe deformation zone in the deformation temperature range of 250-300 ℃ and the strain rate range of 0.3-1 s -1. The optimal processing parameters obtained in the present work are the temperature range of 300-400 ℃ and strain rates of 0.01-1 s -1.  相似文献

The effect of silicon on the eutectic carbides in as-heated M2 high speed steels is investigated by using optical microscope, scanning electron microscope, energy dispersive spectrometer and X-ray diffraction analysis. The high speed steel ingots with different silicon additions are produced by electroslag remelting process (the mass content of silicon is 0.3%, 0.8%, 1.6% and 2.4%, respectively). The ingots are annealed at 780 ℃ for 10 h and heated at 1 165 ℃ for 2.5 h. The results show that the eutectic carbides distributed in the dendrites with continuous or semi-continuous net-shape in the as-annealed ingots. The eutectic carbides change from lamellar-like M2C to herringbone-like M6C with the increase of silicon content. After 2.5 h heating at 1 165 ℃, the lamellar-like M2C decomposes into granular M6C and MC, and the size of granules in M2 high speed steel ingot with 0.8%Si addition is smaller than that in the 0.3%Si. Whereas herringbone-like M6C is unchanged during heating treatment, and coarse primary blocky carbides which are harmful for properties still exists after the deformation.  相似文献

[Objectve] To screen the optimal root-controlling reagents for container seedlings of Aquilaria sinensis( Lour.) Gilg,and to enhance the survival rate during transplanting. [Methods] Three different chemical reagents were selected with the concentrations being 50-200 g / L. Chemical reagents were added into emulsion,and together applied to the inner wall of black nutrition pot. The size of container was50 cm × 50 cm; and substrate ratio was turfy soil∶ perlite = 3∶ 1. After cultivated for three months,the seedling height,ground diameter,principal root length,number and length of primary lateral roots( length 5 cm) were measured. Data treatment and analyses were carried out by Spss 16. 0 and Excel 2007 software. Effects of different concentrations of chemical reagents on the growth of container seedlings of A. sinensis were compared. [Results] All the three chemical reagents had significant effects on the seedling height,ground diameter,length of principal roots,number and length of primary lateral roots of A. sinensis. Chemical reagents had shortening effects on the average lengths of principal roots and primary lateral roots,and enhanced the number of primary lateral roots. The influencing degrees of three chemical reagents on the growth of container seedlings of A. sinensis were in the order of CuC O3 AlC l3 ZnC l2. Adding 100- 150 g / L CuC O3 could control the lengths of principal roots and primary lateral roots and enhance the number of primary lateral roots. Therefore,100- 150 g / L CuC O3 was selected. [Conclusions] Adding 100- 150 g / L CuC O3 effectively controlled the root system of container seedlings,and enhanced the survival rate during transplanting of A. sinensis.  相似文献

A new triazole-phenylamide derivative (DOT) is synthesized and its inhibiting action on the corrosion of mild steel in 1 mol/L HCl solution is investigated by means of potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and weight loss measurements. Thermodynamic and kinetic parameters are calculated and discussed. Then the surface morphology is studied by scanning electron microscopy (SEM). Results show that DOT strongly inhibits the corrosion of Q235. The inhibition efficiency of 0.001 mol·L-1 DOT is more than 96%. Polarization curves indicate that the DOT acts as a mixed-type inhibitor, the cathodic and anodic processes of corrosion are suppressed. Thermodynamic and kinetic parameters are obtained from weight loss of the different experimental temperatures, which suggests that at different temperatures (298~333 K) the adsorption of DOT on metal surface obey Langmuir adsorption isotherm model. The adsorption processes are exothermic reaction and belong to chemisorption and physisorption.  相似文献

Stable short-cut nitrification was achieved through the selective inhibition of free ammonia (FA), free nitrous acid (FNA) on the nitrifying bacteria and a real-time control strategy which used pH, DO and ORP as parameters in an SBR reactor. The effects of C/N ratio and initial pH value on the short-cut biological nitrogen removal were studied. It is found that: when influent NH4 +-N concentration was 108~177.3 mg/L, the nitrite accumulation rate was around 90%. The reasons for the favorable nitrite accumulation rate were both the inhibition of FA and FNA on the NOB and the real-time control strategy through detecting the “ammonia valley” and “nitrite knee” two feature points in pH and ORP profiles, respectively. The optimal C/N ratio was 3 when acetate was used as the carbon source. When the denitrification rate with respect to the concentration of mixed liquor suspended solids was 19.8 mg·g -1·h -1 NOx --N,NH4 +-N, NO2 --N, NO3 --N, TN of the effluent were less than 6, 2, 1 and 30 mg/L, respectively. When initial pH value was 8.5, the denitrification rate was maximum. However the differences of denitrification rate were small when pH was in the range of 7.5~8.5.  相似文献

[Objective] To observe the direct killing effects of cinnamaldehyde and volatile oils from RAMULUS CINNAMOMI on inoculated mouse-lung adapted strains of influenza virus A / PR /8 /34( H1N1),and to discuss the TLR7 signaling mechanism of their anti-influenza effects. [Methods]1 With Madin-Darby canine kidney( MDCK) infected by influenza virus as the vector,the effective concentration( IC50)and therapeutic index( TI) of the two drugs were detected in inhibiting the proliferation influenza virus in vitro. 2 Effects of two drugs on the IFN-β secretion of infected MDCK cells were detected by ELISA method. 3Effects of two drugs on the TLR3,TLR7,TRAF-3,IRAK-4 and IFN-β mRNA expression of infected MDCK cells were observed by Real-Time PCR method. [Results]1 Cinnamaldehyde and volatile oils of RAMULUS CINNAMOMI had significant direct killing effects on influenza virus; their IC50 were 5. 77 × 10- 7and 1. 85 × 10- 7m L / m L,and the TI were 9. 51 and 27. 04,respectively. 2 Compared with virus control group,0. 25 × 10- 5m L / m L cinnamaldehyde and volatile oils of RAMULUS CINNAMOMI could significantly enhance the IFN-β content in supernatant of infected cells( P 0. 05). 3 Compared with virus control group,0. 25 × 10- 5m L / m L cinnamaldehyde and volatile oils of RAMULUS CINNAMOMI could significantly increase the TLR7,IRAK-4 and IFN-β mRNA expression levels of infected cells( P 0. 05).[Conclusions] Cinnamaldehyde and volatile oils of RAMULUS CINNAMOMI showed significant inhibitory effects on the proliferation of H1N1 influenza virus. Its antiviral mechanism might be related to the stimulation of TLR7 pathway,the activation of IRAK-4,and the high expression of IRAK-4.  相似文献
