Effect of Arsenic in germination, growth and biochemistry of Rice (Oryza sativa)

Effect of Arsenic in germination, growth and biochemistry of Rice (Oryza sativa)



Priyanka Biswas, Syed Yakub Ali, Pulak Kumar Patra*



Arsenic is a highly toxic metalloid element and occurs
in many minerals, usually in conjunction with sulfur and metals, and
also as a pure elemental crystal. Arsenic poisoning from naturally
occurring arsenic compounds in drinking water remains a problem in many
parts of the world. Arsenic contaminated water is also used in the
agricultural field for irrigation purpose. The influence of 0, 1, 2 and
4mg/l sodium arsenite on germination, seedling growth and biochemistry
of two varieties of Rice (Oryza sativa), Nayanmani and Satabdi was
studied under controlled conditions. After 3 weeks the various
parameters (percentage of seed germination, root and shoot length, dry
biomass, chlorophyll, peroxidase, protein and ascorbic acid content)
were estimated following standard procedures. It was observed that the
root and shoot length, germination percentage, dry biomass, protein
content, chlorophyll, ascorbic acid content and peroxidase activity
decreased significantly with increasing exposure to arsenic in both the
plant varieties. The study shows that arsenic is toxic to both rice
varieties and affects adversely the normal rate of germination and
growth through alteration in the plant biochemistry.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
