土壤镉胁迫对龙葵(Solanum nigrum L.)幼苗生长及生理特性的影响

采用盆栽试验研究了不同浓度Cd(0、10、20、40、80、160 mg·kg-1)处理下,龙葵(Solanum nigrum L.)幼苗对氮(N)、磷(P)和钾(K)吸收及质膜ATPase活性的影响。结果表明,土壤添加Cd浓度≤40 mg·kg-1时显著促进龙葵幼苗生长及生物量的积累与分配,添加Cd浓度>40 mg·kg-1时抑制作用加强;叶绿素含量随Cd添加浓度的增大而下降,在较低浓度Cd(10 mg·kg-1)处理时,显著提高叶绿素含量。随Cd添加浓度的增加,根、茎、叶和果实中的全N、全P和全K含量先升后降(除茎全P降低外);叶片中的Cd积累量最高,茎次之,果实中最低;丙二醛含量与过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性增大,但超氧化物歧化酶(POD)活性先升后降;幼苗地上(茎与叶)和地下(根)部H+-ATP以及地下部Ca2+-ATP酶活性随Cd添加浓度的增加不断降低,而地上部Ca2+-ATP酶活性则先升后降。这些结果表明,龙葵在高Cd胁迫(≥40 mg·kg-1)下,能通过加快根系对Cd离子积累来提高抗氧化酶(CAT和SOD)活性、降低POD与质膜ATP酶活性、改变对N、P和K的吸收,从而起到对Cd胁迫的解毒作用。

Antioxygenic Activity of <i>Solanum nigrum L.</i>Leaves in Sunflower Oil Model System and Its Thermal Stability

The antioxygenic activity of Solanum nigrum L. leaves and its various solvent extracts were evaluated using sunflower oil model system. Leaf powder and its methanol/water (80:20) soluble fraction showed strong antioxygenic activity in refined sunflower oil. On the other hand, ethyl acetate fraction exhibited marginal antioxygenic activity, whereas the water soluble fraction was practically devoid of any activity in refined sunflower oil. Thermal stability of different extracts of Solanum nigrum L. leaves heated at 80?C in refined sunflower oil also indicated the strong efficacy of methanol/water (80:20) extract to inhibit thermal oxidation. Solanum nigrum L. contain high levels of magnesium (239.0 mg/100g) and phosphorous (80.3 mg/100g). Fatty acid analysis of the lipid extracted from Solanum nigrum L. leaves indicated the presence of linoleic (59.1%) as a major fatty acid. The result of this study confirmed the presence of antioxygenic compounds in leaves, in particular its methanol/water (80:20) extracts showed great potential as a natural antioxidant to inhibit lipid peroxidation in foods.

为了解外源表油菜素内酯(EBL)对龙葵镉(Cd)胁迫的调节作用,对100μmol L-1 Cd胁迫处理7 d和20 d后的龙葵喷施10-9、10-5 mol L-1 EBL 7 d,研究其生长状况、不同器官的生理生化作用以及3个泛素基因(Rma1、BUB、UBC)的表达变化.结果表明:与对照相比,Cd胁迫下龙葵叶片和根部MDA含量、抗氧化酶(POD、SOD、CAT)活性升高,表明Cd对龙葵有一定的毒害作用.与单一Cd胁迫相比,外源EBL(10-9、10-5 mol L-1)处理下龙葵株高、根长、干重、鲜重显著(P<0.05)增加,而叶绿素含量增加不显著.与单一Cd胁迫7 d相比,EBL(10-9、10-5 mol L-1)+Cd处理组叶片和根部抗氧化酶活性增加不显著,其中10-9 mol L-1 EBL+Cd处理组叶片MDA含量显著(P<0.05)降低,泛素基因UBC、Rma1表达上调;10-5 mol L-1EBL+Cd处理组叶片Rma1表达上调.与单一Cd胁迫20 d相比,10-9 mol L-1 EBL+Cd处理组叶片和根部MDA含量降低显著(P<0.05),叶片和根部SOD、CAT活性以及叶片POD活性增加显著(P<0.05),叶片Rma1基因和根部BUB、UBC基因表达上调;10-5 mol L-1 EBL+Cd处理组叶片BUB、UBC基因和根部UBC基因表达上调.本研究表明Cd胁迫后,EBL通过提高叶片和根部抗氧化酶系统活性,减轻膜脂过氧化程度来缓解Cd胁迫对龙葵的损伤,并且泛素Rma1、BUB、UBC基因参与该过程,且表达存在时空特异性;当Cd胁迫20 d时,以10-9 mol L-1 EBL对龙葵的缓解作用更为显著.

The effects of different electrode materials on seed germination of Solanum nigrum L.and its Cd accumulation in soil

The effects of different electrode on Solanum nigrum L.seed germination were determined.The result showed that germination percentage(GP)of seeds in treatment T2(titanium elec-trode)was 26.6%higher than in control(CK,without electric field).High potassium and calcium concentrations were beneficial for seed enzymatic activity in treatment T2,which could partly explain the increase in GP.Cd accumulation(μg/pot)in S.nigrum treated with any electric field was significantly higher(p<0.05)than in CK without electric field.Specif-ically,Cd accumulation under the treatment T3(stainless steel electrode)was the highest both in roots and shoots;this accumulation in shoots and roots were 74.7%and 67.4%higher for stainless steel than in CK.This increase must have been associated with a higher Cd concentration in plants and did not exert a significant effect on the biomass.In par-ticular,Cd concentrations in roots and shoots under stainless steel treatment were both significantly higher than in CK(p<0.05),which had to be related to the higher available Cd concentration in the soil in the middle region.Furthermore,it could be attributed to al-tered soil pH and other soil properties.Moreover,none of the biomasses were significantly affected(p<0.05)by different electrode materials compared to CK.

2,4-EBL对不同浓度镉胁迫下龙葵(Solanum nigrum L.)幼苗的缓解作用

A newly-discovered Cd-hyperaccumulator Solanum nigrum L.

A systematic investigation was conducted to screen for cadmium-hyperaccumulator from 54 species in 20 weed families using outdoor pot-culture experiment and small-scale field experiment. The results from the outdoor pot-culture experiment showed that Cd concentrations in the stems and leaves of Solanum nigrum L. growing in a soil spiked with 25 mg/kg Cd were up to 103.8 and 124.6 mg/kg (DW), respectively, which was greater than 100 mg/kg, minimum Cd concentration for a Cd-hyperaccumulator. The Cdenrichment factor(EF,concentration ratio in plant to soil) in shoots was as high as 2.68. Moreover, Cd accumulation in shoots was greater than that in roots (TF, concentration ratio in shoots to roots) and the plant biomass growth was not inhibited at the Cd concentrations tested compared with the control. The results of the small-scale field experiment also showed that the characteristics of Cd accumulation in S. nigrum were all consistent with the characteristics of Cd-hyperaccumulators. Thus S. nigrum can be classified as a Cd-hyperaccumulator. This work is important for further research in the areas of hyperaccumulators screening, and plant-tolerance physiology and evolution. It provides a pat- entable new plant species for phytoremediation of Cd-con- taminated soils.

Stress Effect of Cadmium Absorption between Aloe and Solanum nigrum L

The stress effect of cadmium absorption between aloe and Solanum nigrum L was studied through a simulation experiment with different cadmium contents in soil. The results showed that the growth characteristics, biomass and Cd content in the plants of aloe and S. nigrum L were closely related to Cd content in the soil, and S. nigrum L and aloe had a strong tolerance to Cd in the experiment, pH of rhizosphere soil with S. ni- grum L and aloe planted was generally higher than that of non-rhizosphere soil, which is related to the planting pattern. Compared with aloe, S. nig- rum L had a stronger capacity to accumulate Cd, and intercropping S. nigrum L and aloe could inhibit aloe＇s absorption of Cd, which is favorable to the safe planting of aloe. In addition, S. nigrum L has the potential to restore polluted soil.

Microwave-assisted extraction of polysaccharides from solanum nigrum

The microwave-assisted method was used to extract polysaccharides from solanum nigrum. The optimum experimental parameters, mechanism of the extraction and the effect of microwave-assisted extraction process on the structures of polysaccharides were investigated. The extract was analyzed by the modified phenol-sulfuric acid method at 490nm. The optimum experimental parameters were obtained by orthogonal experiments as follows: extraction time 15min, microwave radiation power 455W and the process ratio of materials mass to solvent volume 1∶20. The results show that compared with the conventional reflux extraction, the microwave-assisted extraction has a higher yield in shorter time, with no effect on the finally obtained polysaccharides as seen from the FT-IR spectra. The scanning electron microscopy images reveal that the mechanism of the extraction is related to the structural changes of the plant cells in different extracting conditions.

Nutritional and Antioxidant Evaluation and Effect of Eggplant Consumption on Anthropometric and Hematologic Parameters in Wistar Rats

The aim of the present study was to evaluate the nutritional quality of green and purple eggplant, their antioxidant activity and their nutritional efficacy on Wistar rats. For nutritional quality, the parameters measured are dry matter, protein, lipid, ash, carbohydrate, iron, phosphorus, calcium, magnesium and energy content. For antioxidant activity, the parameters measured are 50% DDPH free radical inhibition concentration and total polyphenol content. Nutritional efficacy was evaluated in rats fed the control diet and in rats fed the three treated diets containing eggplant meal obtained by replacing 5%, 10%, and 15% of the control diet. The parameters measured are the amount consumed, the weight of the animal and target organs, and hematologic parameters. The results of the nutritional analysis show the following values: 13.31% protein, 2.66% lipids, 0.84% calcium, 0.12% magnesium, 0.43% phosphorus for the Solanum aethiopicum L. species and 13.47% protein, 3.66% lipids, 0.36% calcium, 0.22% magnesium, 0.35% phosphorus for the Solanum melongena L. species. In terms of antioxidant activity, we obtained DDPH inhibition percentages of 40.28 mg/ml for Solanum aethiopicum L. and 12.42 mg/ml for Solanum melongena L., respectively. Finally, hematologic and anthropometric tests showed that for the different diets used, weight loss and an increase in hematologic parameters were observed in the rats tested. This study showed that eggplant has interesting nutritional characteristics and antioxidant activity, contributing to an increase in weight and anthropometric parameters.
