An experiment was conducted at the Mycology laboratory, Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to find out the efficacy of selected botanical extracts against Botrytis gladiolorum (Bg) causing gladiolus leaf blight. Infected leaves samples were collected from gladiolus farmers’ field and brought to the laboratory for study. Ten selected botanicals were used against the colony growth of (Bg). The botanicals were Mehendi, Chrysanthemum, Basil (Tulsi), Onion, Neem, Bael, Arjuna, Garlic, Aloevera (Ghritkumary) and Turmeric. Botanical extracts were applied at the rate of 5%, 10% and 20%. The radial mycelia growth was found minimum (11.60 mm) in garlic extract treated plate at the dose of 5% at 5 DAI, which was statistically similar with turmeric extract treated (14.00 mm) plate and the inhibition of growth was 60% and 51.72%, respectively. Similar trend was found at 10 DAI and 15 DAI. At 15 DAI, garlic and turmeric extract gave the best result against Bg, which was statistically similar with onion (50.07% inhibition) and mehendi (49.93%). All botanicals showed significantly different results over control and found effective in reducing the mycelial growth at the dose of 10%. At 5 DAI, no radial mycelia growth was found in garlic treated plate, which was statistically similar with onion treated plate, means that the inhibition of growth was 100%. Similar trend was also found at 10 DAI, and 15 DAI but at 15 DAI, onion (30.20 mm) gave the statistically similar results with Garlic (30.10 mm) and the mycelia growth inhibition was (57.70%) and (57.84%), respectively. In case of 20% dose, garlic extract showed the best result at 5 DAI and the radial mycelia growth was found minimum (00.00 mm) which was statistically similar with onion extract treated (00.00 mm) plate and turmeric extract treated plate. The inhibition of growth was 100%. At 15 DAI, the inhibition of fungal growth was found (73.74%), (71.23%) and (66.90%), respecti

Nazibur Rahman Biomedical and Toxicological Research Institute (BTRI) Institute of Food Science and Technology Bangladesh Council of Scientific and Industrial Research (BCSIR) Dhaka Bangladesh Department of Food Technology and Nutritional Science Mawlana Bhashani Science and Technology University Tangail Bangladesh WAFFEN Research Laboratory Dhaka Bangladesh Department of Biochemistry and Molecular Biology Jahangirnagar University Savar Bangladesh

The main purpose of the study was to reveal the hypoglycemic effect of a combination of some selected spices along with the evaluation of nutritional values. A sum of fourteen different types of spices at different percentages were taken into consideration to propel the research activities forward, viz;ginger, garlic, onion, red chili, turmeric, cumin, cinnamon, clove, coriander, fenugreek, black pepper, nigella, carom seed and cardamom. The healthy experimental wistar albino rats were made diabetic by injecting alloxan monohydrate intraperitoneally a dose of 150 mg/kg body weight. The rats of Group-D and Group-E were treated with the sample, mixed spices at a dose of 100 mg/kg and 200 mg/kg body weight respectively with the lab diet while in case of Group-C, glibenclamide at a dose of 0.5 mg/kg body weight was introduced with the lab diet for a total period of 21 days where as for the same days span, Group-A and Group-B were continued feeding with only lab diet. Data suggest that the mixed spices of both doses applied in Group-D and Group-E had exerted effects significantly (p 0.05) in lowering the blood glucose level. On 22nd day, in Group-D and Group-E, the FBG level was found to be reduced by around 40.66% and 41.18% respectively compared to their respective initial days where in Group-C, the reduction was around 51.90% in comparison to its initial day. Again, in case of 2hPG level measurement, on 22nd day, both the groups, Group-D and Group-E were found with the decreased level of around 19.38% and 39.11% respectively compared to their respective initial days while the Group-C was shown with the reduced of 44.26% in comparison adopting same manner. Furthermore, various analyses confirm the presence of several micro and macro nutrients and high amount of dietary fiber in the spices mix. Thus the result affirms that this combined spice possesses strong hypoglycemic properties.

American Journal of Plant Sciences 2018年第7期9卷 1557-1576页

作者： M. Maniruzzaman J. C. Biswas M. B. Hossain M. M. Haque U. A. Naher A. K. Choudhury S. akhter F. Ahmed R. Sen S. Ishtiaque M. M. Rahman N. Kalra Bangladesh Rice Research Institute (BRRI) Gazipur Bangladesh Bangladesh Agricultural Research Institute (BARI) Gazipur Bangladesh Bangabandhu Sheik Mujibur Rahman Agricultural University (BSMRAU) Gazipur Bangladesh Indian Agricultural Research Institute New Delhi India

Agricultural productivity is affected by air temperature and CO2 concentration. The relationships among grain yields of dry season irrigated rice (Boro) varieties (BRRI dhan28, BRRI dhan29 and BRRI dhan58) with increased temperatures and CO2 concentrations were investigated for futuristic crop management in six regions of Bangladesh using CERES-Rice model (DSSATv4.6). Maximum and minimum temperature increase rates considered were 0°C, +1°C, +2°C, +3°C and +4°C and CO2 concentrations were ambient (380), 421, 538, 670 and 936 ppm. At ambient temperature and CO2 concentration, attainable grain yields varied from 6506 to 8076 kg·ha-1 depending on rice varieties. In general, grain yield reduction would be the highest (13% - 23%) if temperature rises by 4°C and growth duration reduction would be 23 - 33 days. Grain yield reductions with 1°C, 2°C and 3°C rise in temperature are likely to be compensated by increased CO2 levels of 421, 538 and 670 ppm, respectively. In future, the highest reduction in grain yield and growth duration would be in cooler region and the least in warmer saline region of the country. Appropriate adaptive techniques like shifting in planting dates, water and nitrogen fertilizer management would be needed to overcome climate change impacts on rice production.

Climate change impacts are visible in Bangladesh which requires adoption of judicious crop management practices for sustainable agriculture. Crop simulation models are effective in this regard and can be used for optimizing water and nitrogen inputs for maximization of wheat yields. Two field studies were conducted at Bangladesh Agricultural Research Institute (BARI) for evaluating the effect of increased temperature on wheat production under variable water and N rates, through the use of DSSAT v4.6 model. Thirty years historic weather data and BARI Gom-26 wheat-cultivar coefficients, as generated through use of GLUE of DSSAT model, were used for evaluating the impact of temperature rise with variable rates of irrigation water and nitrogen. The effects of four levels of nitrogen (0, 40, 80 and 120 kg ha-1) and four irrigation levels [0 (no irrigation), 1, 2 and 3] on wheat yield were evaluated under 0°C, 1°C, 2°C and 3°C rise in temperature. Simulation results indicated that wheat yield increased with increase in nitrogen application rate, but decreased with the temperature rise. Crop growing duration was reduced by about five days for each degree rise in temperature, irrespective of levels of irrigation water and nitrogen-rates. In general, there was yield reduction of 8.13, 16.77 and 24.97 % with increased temperature of 1°C, 2°C and 3°C, respectively, when compared with no temperature rise treatment. For interaction of temperature rise-N dose, the magnitude of yield decline under temperature rise was higher with increased dose of N. Agronomic N use efficiency at different N rates and temperature rise level were calculated. N use efficiency decreases with the increase in temperature rise and the highest (29.95 kg grain kg-1 N) was obtained from 40 kg N ha-1 treated plot with 0°C temperature rise i.e. existing atmospheric temperature. Simulation results indicated increase in wheat yield with higher levels of irrigation water, and int

Maize is an emerging important crop in Bangladesh because of its high yield potential and economic profitability compared to rice and wheat crops. There is a need to understand the growth and yield behavior of this crop in varying production environments of Bangladesh. Crop model such as Decision Support System For Agro-technology Transfer (DSSAT) version 4.6 (DSSAT hereafter) can be utilized cost effectively to study the performances of maize under different production environments. It needs to calibrate and validate DSSAT model for commonly cultivated maize cultivars in Bangladesh and subsequently take the model to various applications, including inputs and agronomic management options and climate change that impacts analyses. So, the present study was undertaken to firstly calibrate DSSAT model for popular four hybrid maize cultivars (BARI Hybrid Maize-7, BARI Hybrid Maize-9, Pioneer 30B07 and NK-40). Subsequently, it proceeded with the validation with independent field data sets for evaluating their growth performances. The genetic coefficients for these cultivars were evaluated by using Genotype coefficient calculator (GENCALC) and Generalized likelihood uncertainty estimation (GLUE) module of DSSAT on the basis of first season experiment. The performance of the model was satisfactory and within the significant limits. After calibration, the model was tested for its performance through validation procedure by using second season data. The model performed satisfactorily through phenology, biomass, leaf area index (LAI) and grain yield. Phenology, as estimated through days to flower initiation and maturity, was in good agreement, although simulated results were slightly over predicted compared to observed values but within the statistical significance limit...when compared with observed values at specific growth stages of the crop. The final yield values (10.12 to 10.59 t·ha-1) were in close agreement with the observed values (10.16 to 10.94 t·ha-1), as the perce

Objective: The purpose of this study was to describe pregnant patients with mitral stenosis who had intracardiac thrombosis in the absence of atrial fibrillation. Study design: We reviewed the clinical course of 3 pregnant women with severe mitral stenosis and normal sinus rhythm who had clinically significant intracardiac thrombosis. Results: The first patient was examined at 21 weeks of gestation with embolic stroke that was the result of left atrial thrombus. A second patient was found to have a large left atrial thrombus that prevented the performance of balloon valvuloplasty. The third patient had left atrial clot that partially occluded the mitral valve orifice and led to the development of pulmonary edema that resulted in an emergent cesarean delivery and anoxic brain injury in the newborn infant. Conclusion: Pregnant patients with mitral stenosis in normal sinus rhythm can experience thromboembolic events that can be detrimental to both the mother and the fetus. Anticoagulation therefore should be strongly considered in this group.
