Authors: Islam Saiful , Jahan Nargis 
Published: April 2020

Leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and leaf area duration (LAD) of a variety of wheat (Triticum aestivum L.) were studied with three concentrations (0, 25 and 50 ppm) of naphthalene acetic acid (NAA) and four levels (0, 50, 75 and 100 %) of Nfertilizer in a field experiment during 2014 - 2015. Results showed that LAI and LAD at all stages of growth increased from control and their peak values were recorded mostly from 25 ppm NAA in combination with 75 % N-fertilizer and 50 ppm NAA in combination with 50% N-fertilizer. RGR was affected both positively and negatively depending on the concentration of NAA and nitrogen levels and was higher at earlier age (15 to 45 DAS) as opposed to later stage irrespective of treatments. CGR and NAR were also affected positively and negatively and tended to increase sharply reaching maximum at 30 - 45 DAS with a few exceptions and then decreased for most of the treatments with the progression of age. At 30 - 45 DAS, peak value of CGR was recorded from 25 ppm NAA in combination with 75% N-fertilizer. Of all the treatments, 25 ppm NAA in combination with 75% N-fertilizer produced better stimulation.

Authors: Jahan Hawa , Tabassum Mehnus , Latifa Gulshan Ara 
Published: April 2020

Work on two freshwater Gobi fish species such as Awaous guamensis and A. grammepomus was carried out on morphometric and meristic study for their morphological identification. Sequence data of mitochondrial cytochrome oxidase subunit I (COI) gene was used for this purpose. Around 620 bp sequences were obtained when universal primers were used. An alignment was performed between the sequences which showed some inter-specific variation. An entropy plot was generated for all the aligned positions which showed that the entropy rarely touches a scale of one, which is a sign of better alignment in the region. This work can be utilized for species identification, phylogenetic analysis, to study molecular diversity and evolution, and most importantly for the conservation of these fauna in near future.

Published: April 2020

Acute hepatopancreatic necrosis disease (AHPND) is an emerging shrimp disease caused by strains of Vibrio parahaemolyticus containing a unique virulent plasmid, responsible for substantial economic losses since 2009; caused up to 100% mortality in farmed shrimp Penaeus monodon. The purpose of this study was to isolate and identify the pathogenic strain of V. parahaemolyticus causing AHPND in cultured shrimp (Penaeus monodon) using classical and molecular techniques. Samples were collected from three different locations of south-west shrimp farming regions of Bangladesh viz. Sadar Upazilla of Satkhira; Mongla and Morrelganj under Bagerhat district. In this study, three selective media were used for primary isolation of V. parahaemolyticus. Among 46 primary isolates, 18 representative isolates were checked for the species-specific detection of V. parahaemolyticus using ldh primers and all of them were found to be positive. 16S rRNA gene sequencing were used to further confirm the isolates as V. parahaemolyticus. tdh primer was used to check human pathogenicity but all 18 isolates showed negative result. The isolates were further characterized to check their AHPND positivity using AP3 and AP4 primers. Ten isolates showed positive results for AP3 (55.56%) and 9 showed positive results for AP4 (50%) which indicated that the isolates were AHPND positive. This study also reported that all AHPND positive strains were resistant to the antibiotic gentamycin but sensitive to chloramphenicol, nalidixic acid, nitrofurantoin and tetracycline. The findings of this study will help the shrimp farmers and policy makers to take proper biosecurity measures to protect shrimps from AHPND and thereby sustain the shrimp production in Bangladesh.

Authors: Dash Chandan Kumar , Alam Sheikh Shamimul , Sultana Syeda Sharmeen 
Published: April 2020

Karyomorphological features of Justicia adhatoda L. were investigated in this study after differential staining with orcein, CMA and DAPI for proper characterization. In this species "Simple Chromocenter Type" of interphase nuclei was observed with many small heterochromatin blocks after orcein staining. Prophase chromosomes showed "Interstitial Type" of staining pattern which indicated the tendency of aggregation of heterochromatin in interstitial regions of chromosome. This species was found to possess 2n = 34 metacentric chromosomes. The total length of 2n chromosome complement was 132.17 μm. Individual chromosome length ranged from 2.57 to 5.43 μm. The relative length of each chromosome ranged from 0.02 to 0.04. A total of seven CMA-positive bands were observed in this species whereas no band was found after DAPIstaining. This result suggested the absence of AT-rich portions and occurrence of GC-rich portions in the respective banded chromosomes. Except 2n chromosome number, the other karyological and fluorescent banding information probably was the first report for this species and it might help to enhance the chromosomal data base with detailed karyomorphological information of this plant species in Bangladesh.

Authors: Helal Rezuana Binte , Shamsi Shamim 
Published: April 2020

Four antagonistic fungi were isolated from the papaya field soil by serial dilution and were identified as Aspergillus flavus Link., A. fumigatus Fresenius, A. niger van Tiegh. and Trichoderma viride Pers. The soil fungi were selected to evaluate their antagonistic potentiality against the three postharvest pathogenic fungi of Carica papaya L. following "dual culture colony interaction” and volatile and non-volatile metabolites. In dual culture colony interaction, out of four soil fungi, T. viride showed the highest growth inhibition on C. gloeosporioides (84.28%), F. nivale (95.23%) and Fusarium sp. (87.15%). On the other hand A. niger showed the highest growth inhibition on C. gloeosporioides (77.39%), F. nivale (98.63%) and Fusarium sp. (35.05%). The maximum inhibition of radial growth of C. gloeosporioides (77.64%), F. nivale (58.76%) and Fusarium sp. (79.37%). were observed in case of T. viride owing to the volatile metabolites. Whereas the maximum inhibition of radial growth of C. gloeosporioides (58.23%), F. nivale (37.43%) and Fusarium sp. (82.31%) were observed in case of A. niger owing to the volatile metabolites. The maximum inhibition of radial growth of C. gloeosporioides (90.90%), F. nivale (89.13%) and Fusarium sp. (76.84%) were observed in case of T. viride owing to the effect of non-volatile metabolites. The maximum inhibition of radial growth of C. gloeosporioides (92.42%), F. nivale (73.01%) and Fusarium sp. (68.67%) were observed in case of A. niger owing to the effect of non-volatile metabolites. Trichoderma viride and A. niger may be exploited commercially as a biocontrol agent against anthracnose and fruit rot pathogens of papaya.

Authors: Ahsan Sunjukta , Islam Riajul 
Published: April 2020

The emergence and rapid dissemination of beta-lactamase-producing E. coli is now a worldwide problem. A total of 45 E. coli obtained from clinical specimens from a medical service centre in Dhaka were selected for this study. Test E. coli exhibited variable resistance to 3rd (71.7 - 97.8%, n = 48) and 4th (78%, n = 48) generation beta-lactam antibiotics, with 72% sensitivity to Carbapenem. Analysis of co-resistance indicated that 33.3% of E. coli (n = 48) were co-resistant to beta-lactams and ciprofloxacin. ESBL producers were predominant comprising of 84.7% E. coli. Among them, 22.7% contained blaTEM, 24.2% contained blaCTX-M, 4.3% contained blaSHV and 9.1% contained blaOXA-1 genes. A total of 25.75% isolates were metallo beta-lactamase producers. Of these, 1.5% of E. coli strains contained New Delhi metallo beta-lactamase gene and 6% contained AmpC gene. Multiple beta-lactamase genes were detected in some test isolates; 6.7% isolates contained 4, 20% contained 3 and 73.3% contained 2 beta lactamase genes. Fifty per cent of the E. coli contained plasmids of variable sizes. In addition, a total of 39% of the E. coli contained Class 1 integron. The increasing trend in beta-lactam resistance is of public health concern as it limits treatment regime and indicates to the need of continuous monitoring of resistance pattern.

Effects of aluminium toxicity on some biochemical components of rice (Oryza sativa L.)
Authors: Samad Rifat , Rashid Parveen , Karmoker JL 
Published: April 2020

An experiment was conducted to investigate the effect of aluminium (Al) toxicity on reducing and total sugar, proline, total amino acid and protein in rice seedlings grown in solution culture and phenolic compounds, chlorophyll and carotenoids in rice plants grown in sand culture. Exposure of rice seedlings to different concentrations of aluminium (10 - 150 μM) led to a stimulation of reducing and total sugar in the root and the shoot. Similarly, Al stress increased proline and total amino acid contents in different parts of rice seedlings. Aluminium toxicity caused a significant increase in phenolic compounds in rice plants. On the other hand, aluminium stress resulted in a reduction of chlorophyll-a, chlorophyll-b and carotenoid contents in the leaves of rice plants.

Tectonics Impact on Poljes and Minor Basins (Case Studies of Dinaric Karst)
Authors: Gams Ivan 
Published: April 2020

Namen te študije je pokazati tektonske poteze v izbranih kraških poljih in manjših kotanjah Dinarskega krasa. Vrtine in gravimetrične meritve so ugotovile debele neogene nesprijete sedimente in apneniško dno pod gladino morja - kriptodepresije. Sedimenti so deli obsežne akumulacijske ravnine, ugreznjeni v kraška polja v spodnjem pliocenu. Seizmična aktivnost v sedanjosti nakazuje še trajajočo tektonsko aktivnost. Najgloblje (čez 100 m) in najmanjše kraško polje v slovenskem Dinarskem krasu, Globodol, je suho kraško polje v piezometrični vodni gladini. Pliokvartarno grezanje dna je edina možna razlaga za nastanek polja. Na Planinskem polju so znaki podtalne korozije in holocenskega tektonskega grezanja dna. Štiri kraška polja v Ravnih kotarih (Dalmacija) dokazujejo proces uravnavanja jezerskega dna pod plitvim pokrovom aluvialnih sedimentov. Izjemno globoke majhne kotanje so okoli 450 m globoko Rdeče jezero (Hercegovina) in kotanji pri Črnomlju in Kočevju (Slovenija), okoli 300 m oziroma 100 m pod gladino morja. The aim of this study is to show tectonic features in selected poljes and minor basins in the Dinaric Karst. Boreholes and gravimetric measurements show thick Neogene loose sediments and the rocky bottom below the sea level - real cryptodepressions. The sediments make parts of a large plain that subsided at the end of the low Pliocene. The recent seismic activity in this area proves the ongoing tectonic process. The deepest (more than 100 m) and the smallest polje in the Slovenian Dinaric karst, Globodol is a dry polje in the piezometric level. Quaternary subsidence of the bottom is the only reasonable explanation of its genesis. On Planinsko polje there are signs ob suballuvial corrosion and the indicators of the Holocene tectonic subsidence. Four poljes in the Ravni kotari (Dalmatia) are shallow basins in the first stage of development. They prove the process of the bottom levelling below the shallow cover of alluvial sediments. An extremely deep small basin is about 450 m deep Red Lake (Hercegovina) and small basins at Črnomelj and Kočevje (Slovenia), 300 m and 100 m deep below the sea level.
