  • Comparative Survey of Lignification in Aerial Organs during Development of
           Sugarcane (Saccharum officinarum L.)

    • Abstract: Publication date:  Jan 2018
      Source:Universal Journal of Plant Science  Volume  6  Number  1  Maryam Kolahi   Mohammad Reza Tabandeh   Majd A   Parisa Jonoubi   and Mahmoud Hashemitabar   Cell-wall lignification is among the new features that appeared as early plants began to adapt to land, possibly aiding in the development of more complex bodies. Saccharum officinarum L., a typical C4 plant with unique structure and anatomy, is one of the most important energy crops in the world with a very high yield of biomass. We analyzed lignification in the anatomy of leaf, sheath and stem, in sugarcane seedlings at four distinct stages of growth: germination stage, tillering stage, ground growth stage and maturation stage. Kranz anatomy with well-developed bundle sheath associated with Kranz mesophyll was observed but Kranz system was absent in large vascular bundles. Lignification of tissues and cells in sheath during early developmental stages is expected confirmed because during this stage, when stem tissue is absent in sugarcane, may be critical for the expansion of lignification and development of the stem and increasing the mechanical rigidity of the young plant. The lignified tissues and the intensity of lignification increased during later stages of development, especially in the stem. The most lignified tissues of the stem can be observed during the maturation stage and a little before it, which provides the stem with mechanical strength. These differentiation features may be linked to stem development, while the relevant changes in metabolites may be related to sucrose accumulation.

  • Nitrogen (N) and Potassium (K) Supplementation to Improve Salt Tolerance
           in Brassica (Brassica juncea, cv: Agati sarheen)

    • Abstract: Publication date:  Jan 2018
      Source:Universal Journal of Plant Science  Volume  6  Number  1  M. U. Shirazi   M. T. Rajput   M. A. Khan   and R. U. Ansari   To observe the mitigating effects of nitrogen and potassium under salinity on Brassica juncea (cv. Agati sarheen), N and K was supplemented at different stages of growth. The studies were conducted under control condition (gravel culture). Salinity (12 dS/m) was imposed by NaCl salt after three weeks of germination through irrigation (1/4th Hoagland solution). Nitrogen and Potassium was applied exogenously in the form of KNO3 @ (T1. 30mM and T2 60mM) at vegetative and flowering stage. There was decrease in growth and yield under salinity. However; the relative reduction in plant height, slique length, grain wt/ 5 slique and grain yield/ 15 plants was comparatively low due foliar application of N and K as compared to non applicated plants. The overall accumulation of organic solutes (proline and glycine betaine) was significantly high under salinity. The response of N and K application was almost nil in case of proline accumulation. On the other hand application of KNO3 @ 30mM showed increased accumulation of glycine betaine. The uptake of Na under salinity was less in plant having KNO3 application @ 30mM (T1). Potassium content under saline condition was high in KNO3 @ 60mM (i.e. T2 treatment), resulting in high K/Na ratio. The application of KNO3 also found to increase in nitrogen content in brassica. It is therefore concluded that better performance of brassica genotype under salinity might be due to low Na uptake and high K/ Na ratio especially under T1 treatment (i.e KNO3 @ 30mM).

  • Antimicrobial, Antifungal & Cytotoxic Activities Screening of Stem Bark
           Fractions from Terminalia chebula

    • Abstract: Publication date:  Sep 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  3  Md. Lutful Kabir   Mohammad Tuhin Ali   and Md. Enamul Haque   The fractionated crude extracts and two isolated pure compounds TC-1(Phytol) and TC-2(Stigmasterol) from stem bark of Terminalia chebula were screened for their antibacterial and antifungal activities and cytotoxicity against brine shrimp nauplii. Petroleum ether, ethyl acetate (EtOAc) and methanol (MeOH) extracts and the compounds isolated from EtOAC fractions were studied for their antimicrobial activities. Cytotoxic activities were conducted only with crude extract. Both EtOAc and petroleum ether extract showed promising and moderate antimicrobial activities against most of the gram positive and gram negative bacteria whereas the MeOH extract did not show any antimicrobial activities. The isolated pure compounds TC-1 & TC-2 exhibited activities against most of the bacterial strains. The cytotoxicity towards brine shrimp nauplii of the crude extract was studied. The LC50 values of plant crude extract is found to be 5.623413µg/mL.

  • Survey and Identification of Common Weeds Associated with Rice and
           Vegetable Production in Rosario, La Union, Philippines

    • Abstract: Publication date:  Sep 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  3  Angelina T. Gonzales   A preliminary survey, collection and identification of weeds in rice and vegetable production areas in Rosario, La Union, Philippines were done to identify most common and prevalent weeds associated with rice and vegetable. Fields surveys were done according to the quantitative survey method using 1.0m x 1.0m size quadrat with 20 samples from each field. Weeds present in each field were identified and the data were used to calculate frequency and relative dominance values for each species. A total of 45 species of weeds were collected and identified. Dominant weeds in vegetable and rice production during wet season were Digitaria sp., F. littoralis, A. conyzoides, C. pubescens and D. aegyptum. However, dominant weeds in rice production area were: Digitaria sp. and Dactyloctenium aegyptium; while Chloris sp. and Fimbristylis littoralis Gaudich, Centrosema pubescens Benth and Cyperus killingia and Cyperus rotundus L. and Dactyloctenium aegyptium at vegetable area. Based on the survey annuals were more dominant than perennial. More survey work is needed on a regular basis to identify possible problematic weed and weed population shifts and direct research toward new or improved control measures.

  • Polyethylene Glycol (PEG) Induced Changes in Germination, Seedling Growth
           and Water Relation Behavior of Wheat (Triticum aestivum L.) Genotypes

    • Abstract: Publication date:  Nov 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  4  Most. Faijunnahar   Abdullahil Baque   Md. Ahsan Habib   and H. M. M. Tariq Hossain   Pre-sowing seed treated with Polyethylene Glycol (PEG) assumed to be a potential priming agent to increase the germination, seedling growth and water relation behavior of grain. With this view, a lab investigation was carried out to find out the effect of various PEG concentrations on the germination, seedling growth and water relation behavior of wheat. Seeds of ESWYT-5, ESWYT -6 and ESWYT-7 wheat genotypes and BARI Gom 28 were pre-soaked in water with 0%, 5%, 10%, 15% and 20% PEG solutions. Results of the study revealed that seed priming enhanced germination, seedling growth and water relation behavior of wheat genotypes. Among four wheat genotypes, ESWYT-5 performed the best regarding germination, seedling growth and water relation behavior where wheat genotypes ESWYT-6 and BARI Gom 28 performed moderately and ESWYT-7 showed consistently poor performance. All the characters showed the best results when wheat seeds treated with 10% PEG solution compared to nonprime and hydro primed seeds and the value decreased gradually with increasing PEG concentration. These results suggest that seed priming had significant effect to boost the germination, seedling growth and water relation behavior of wheat genotypes.

  • Status of Agricultural Statistics in Sudan

    • Abstract: Publication date:  Jul 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  2  Nuha Mohamed Elamin Ahmed   and Mawahib Elsaied   Agriculture is playing a very important role in the Sudan economy of the country as more than 70 per cent of the population is engaged directly or indirectly in this activity. Sudan earns 45 per cent of its GDP from Agriculture. The current paper presents evolution of statistical activities and setting up of its institution is taken up since 1903. The objectives of the survey were: To estimate the average yield per feddan and consequently estimate the total production of sorghum; to estimate the harvested area depending on response from the selected farmers by identifying planted and harvested area; and also the same sample or a sub sample can be used to collect information on cost of production and marketing of agricultural products. The survey design used was stratified two stage random sample with uniform sampling fraction (proportionate allocation). For collection of data the agriculture sector in the country was divided into "Irrigated" and "Rainfed" sectors. Rainfedsector was further divided into "mechanized" and "traditional" sectors for the purposes of sampling designs. The country prepares Balance Sheet Cereal of and has a methodology for assessment of Food and Nutrition Security. The paper also outlined the existing Market Information System for Crop and Livestock.

  • Enhancing Strawberry Productivity through Bee Pollination

    • Abstract: Publication date:  Jul 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  2  Asiko Grace   Oketch Jane   Mochorwa Jared   Nzano Patricia   Momanyi Dinah   Okecha Teresa   Okinyi Blaise   Koech Christine   Yego Ruth   and Palla David   Bees play a vital role in strawberry pollination, for fruit quality and increased productivity. Greenhouse experiments were conducted at the National Beekeeping Institute, in collaboration with EU-AU Sponsored ICIPE Bee Health Project. Using honeybee pollinators increased super quality fruits (84% total). Harvested industry fruits were absent in the open field plants, outside the greenhouse, with multi-pollinators. These, however, greatly reduced in the harvested fruits, inside the greenhouse (4.3% total), with the honeybee as the sole pollinator, demonstrating the superiority of the latter in enhancing strawberry productivity through pollination.

  • Susceptibility, Antioxidant Defense, and Growth Inhibitory Response of
           Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) against the
           Virulence of Metarhizium anisopliae Isolates

    • Abstract: Publication date:  Jul 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  2  Abid Hussain   Muhammad Rizwan-ul-Haq   and Ahmed Mohammed AlJabr   Rhynchophorus ferrugineus, commonly referred to as red palm weevil (RPW), is an invasive Indian sub-continent pest that infests date palms in the Arabian peninsula and dates-growing countries. In an effort to manage red palm weevil infestations, exotic isolates of entomopathogenic fungi, especially Metarhizium anisopliae were procured from different sources for possible use against red palm weevil larvae. In this study, we evaluated the virulence attributes including the viability and relative hydrophobicity of the spores of M. anisopliae isolates 8453, 7234 and 406; and their impact on the host susceptibility, growth and antioxidant defense. Results indicated that isolate 8453 had 20.64% higher relative hydrophobicity compared with the least virulent isolate 406 that showed the highest LT50 value (10.90 days). The feeding performance experiment revealed significant differences in ECI and ECD indexes. The most virulent isolate 8453 (LT50 = 7.55 days) established in the current study tremendously declined ECI (26.15%) and ECD (39.84%) indexes compared to control treatment larvae. However, the least virulent isolate 406 (LT50 = 10.90 days) could only reduce 7.38% and 12.06% of ECI and ECD indexes, respectively. Furthermore, the virulent isolate 8453 established in the current study successful imparted 100% larval mortality compared with other tested isolates of M. anisopliae. Host antioxidant defense from hemolymph, gut and fat was explored after 24 h of infection by qRT-PCR. The quantification of catalase and peroxidase genes revealed significant differences in their expressions. Overall, the least virulent isolate (406) failed to induce the expression of catalase and peroxidase. However, isolate 8453 greatly induced the expression of studied antioxidant genes. These results indicated that M. anisopliae isolate 8453 seems to be a promising bio-control agent against the infestations of red palm weevils.

  • Stimulation of Defense Enzymes in Tomato (Solanum lycopersicum L.) and
           Chilli (Capsicum annuum L.) in Response to Exogenous Application of
           Different Chemical Elicitors

    • Abstract: Publication date:  Apr 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  1  Y.S.M. Asanka Indunil Kumari   and A. Vengadaramana   The objective of this study was to evaluate the response to exogenous application of different chemical elicitors on the stimulation of defense enzymes such as chitinase, peroxidase, phenylalanine ammonialyase (PAL) and polyphenoloxidase (PPO) in tomato and chilli plants leaves tissues. Chemical elicitors are compounds, which activate chemical defense systems in plants. Various biosynthetic pathways are activated by chemical elicitors in plants depending on the elicitors used. Two times exogenous application of 200 ppm of salicylic acid (SA), ascorbic acid (AA), jasmonic acid (JA) and H2O2 and ethanol (1 mL of 95% ethanol in 1 L distilled water) induced the four defense enzymes production in chilli and tomato plants leaves tissues and significantly reduced viral disease incidence in chilli plants compared to control. SA at 200 ppm enhanced significantly chitinase, peroxidase, PAL and PPO enzymes in leaves tissues of tomato plants. Tomato plants treated with chemical elicitors and control did not show any disease symptoms.

  • Managing Ambient Air Quality Using Ornamental Plants-An Alternative
           Approach

    • Abstract: Publication date:  Apr 2017
      Source:Universal Journal of Plant Science  Volume  5  Number  1  Manish Kapoor   Air quality management involves the determination of the relative contribution of current or future source emissions at receptor sites to ground level pollutant concentrations coupled with implementation of effective management plan to reduce emission level. From the last few decades, urban air pollution has become an inevitable issue for its possible consequences on public health. In order to manage the ambient air quality, there are several methodologies with each having some specific advantages and constrains. Improvement of ambient air quality involves the basic approaches like emission reduction at source level, conversion of pollutants to a less damaging compounds and sequestration of pollutants. However, in order to manage the air quality, application of ornamental plants may be considered a well alternative approach. Although, it may not be imperative to consider plants as a sole alternative for urban ambient air quality management, but certainly it may useful to manage air quality for a small confined area, especially in case of indoor air. This paper reviews the possible application of ornamental plants, which may be trees, shrubs or herbs for its possible applications to regulate air quality. Some selective plant species has also been recommended based on its air pollution tolerance index.
