Sucrose is the prime product of sugarcane hence continued research is needed to improve its level in cane stalk. Bio-physiological aspects with relation to growth and sucrose storage mechanism are still poorly understood though the morphology and anatomy of sugarcane has been extensively studied. Still too many gaps exist in our knowledge as far as unique development, physiology and synthesis/degradation of sucrose in sugarcane are concerned. It is imperative to first visualize the impact of a selected trait on general sugarcane physiology as crop is highly compensatory in nature. Eventually, these gaps have slow down the precise improvement to enhance the expression of desired agronomical traits. Increased photosynthetic capacity of variety concomitant with increased cane yield has no value unless until sugar content is increased in that proportion. Realistically, it is difficult to increase sucrose level in cane stalk without prior knowledge of the factors that affect sugarcane yield and carbon partitioning. Since many genes involved in the metabolism of sucrose including signals and factors responsible for its regulation, further complicates the situation. Factors related to multiple environmental constraints namely temperature, water deficit and excess, increased CO2 and availability of nutrient directly or indirectly influence or cross talk the controlling pathways of growth and sucrose metabolism. In the present review an attempt has been made to discuss and explore the possibility of enhancing sucrose productivity in sugarcane addressing the issues pertaining to physiology, biochemistry and biotechnology primarily focusing India as the active centre for the sugar and sugarcane production. © 2011 Society for Sugar Research & Promotion.

Web-based expert system development has been considered as complex, multidisciplinary and knowledge driven process. This paper presents a framework for development of web-based expert system with integrated approach of MAS-CommonKADS agent-oriented methodology, Model-View-Controller (MVC) architecture and web applications optimization strategies to deal with complexity of development and to achieve high usability. Study will guide in software engineering of developing such system with respect to Internet Technologies. Application of proposed framework for developing web-based expert system in sugarcane disorder diagnosis has been demonstrated. Results indicate that proposed methodology better deal with complexity of web-based expert system development and usability. © 2010 Elsevier Ltd. All rights reserved. Source

A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for detecting Sugarcane mosaic virus (SCMV) and Sorghum mosaic virus (SrMV) in sugarcane. Six sets of four primers corresponding to the conserved coat protein gene were designed and tested for each virus. Three primer sets designed for detecting SCMV and four for detecting SrMV were successful in the RT-LAMP assay. The effective primer sets were not only specific for their target virus, but also able to detect multiple virus strains. The magnesium sulfate concentration of the reaction solution was optimized, with both viruses requiring a minimum of 5. mM for detection. The sensitivity of this RT-LAMP assay was less than that of conventional and real-time RT-PCR. © 2014. Source

In jaggery making furnaces, sugarcane bagasse is used as fuel. Moisture content of bagasse affects its calorific value. So burning of bagasse at suitable level of moisture is essential from the viewpoint of furnace performance. Moisture content can also be used for indirect calculation of fibre content in sugarcane. Normally gravimetric method is used for moisture content determination, which is time consuming. Therefore, an attempt has been made to use microwave oven for drying of bagasse. It took about 20 to 25 minutes for the determination as compared to 8-10 hours in conventional hot air drying method and the results were comparable to the values obtained from hot air drying method. © School of Engineering.

Electrical properties of edible oil depend upon its total polar component, temperature and the frequency of the applied voltage. Dielectric constant, dielectric loss tangent and electrical conductivity were measured for cottonseed (Gossypium sp.), ground nut (Apios americana), mustard (Brasicca compestriss) and sun flower (Helianthus annuus) oils in the temperature range of 20 to 100 C so as to assess the potential of their applicability for assessing the quality of oils. Viscosity of the oils is an other important physical property associated with their processing and quality control. Viscosity of these oils was experimentally measured. The correlation of viscosity with dielectric loss tangent and viscosity with electrical conductivity were tested. The best correlating relations along with correlation constants, valid for the temperature range of 20-100 C are presented. The regression equation developed relating viscosity with loss tangent and electrical conductivity had high correlation coefficient (R2 > 0.96) for all the four oils within temperature range of 20-100 C. © 2011 Association of Food Scientists & Technologists (India).
