The effect of sugar mill effluent on seed germination of green gram (Vigna radiatia L.)

Sugar industry is an agro-based industry in India which released lot of effluent into the environment during sugar production. The formers used this effluent in agriculture for scarcity of water. The effluent contained large amount of organic and inorganic materials which affects the water, soil and living organisms especially plants. The present study was the analysis of sugar mill effluent and different concentrations (10, 25, 50, 75 and 100%)  of sugar mill effluent effects on germination and growth development of green gram (Vigna radiata L.). As a result the lower concentration (10%) of sugar mill effluent promoted the germination and growth of the seedlings but higher concentrations of sugar mill effluent inhibited the germination and growth of the green gram seedlings. The lower concentration of effluent contained may be better nutrients of plant which used for irrigation purposed for high growth and yield

Effect of various concentrations of chromium polluted soil on biochemical changes of Globe amaranth (Gomphrena globosa L.)

An attempt was made to study the effect of different concentrations of chromium on biochemical  specifications on response of Globe amaranth (Gomphrena globosa L.). The seeds were obtained from Private Agro centre, Villupuram District, Tamil Nadu, India. The healthy seeds of globe amaranth were chosen and used for both laboratory experiments. The various Cr concentrations were used (25, 50, 75 and 100 mg/l). Biochemical parameter such as, protein, amino acid, sugar and proline contents in leaf, stem and root of globe amaranth at 15, 30, 45 and 60 DAS in chromium polluted soil. Among the results protein, sugars and amino acid contents in leaf, stem and root were also significantly decreased in all different concentration of Cr treated as compared to control plants. On the other hand, proline content in leaf, stem and root were increased in all the Cr treated plants as compared to control. To sum up protein, sugars and amino acid were also significantly decreased while, proline content was increased in all the chromium treated plants

Polymorphism in B-DNA: X-ray diffraction studies on Li-DNA fibres

From X-ray diffraction studies it is generally believed that B-DNA has the structural parameters n=10 and h=3.4 Å. However, for the first time we report that polymorphism in the B-form can be observed in DNA fibres. This was achieved by the precise control of salt and humidity in fibres and by the application of the precession method of X-ray diffraction to DNA fibres. The significant result obtained is that n=10 is not observed for crystalline fibre patterns. In fact, n=10 and h=3.4 Å are not found to occur simultaneously. Instead, a range of values, n=9.6-10.0 and h=3.35 Å-3.41 Å is observed

Stock assessment and exploitation status of Lethrinus nebulosus (Lacepede, 1802) exploited off Thoothukudi coast, Tamil Nadu, India

825-828Lethrinus nebulosus (Lacepede, 1802), although a commercially important fish species, has not been studied (population studies) in Thoothukudi coast of Tamil Nadu, India. Research on recruitment pattern, virtual population analysis and exploitation status of L. nebulosus off Thoothukudi coast was conducted from July 2011 to June 2012. During the study period, 4590 specimens of L. nebulosus were collected for studying the above said parameters by using FiSAT software. Recruitment pattern of the species expressed continuously with one peak each in April and August. The fishing pressure occurred more in the length group of 43 cm onwards. The results revealed that the total annual catch of 7566.28 tonnes was obtained from 52210 boat days. The maximum catch per unit was during December and January. The maximum sustainable yield (MSY) was estimated at 12203.68 tonnes. The discrepancy between MSY and annual catch was 4664.399. The present fishing effort may be increased to 61.29% to achieve MSY with 19310 boat days. It was revealed that L. nebulosus is underexploited in this region

Bioreclamation of Sugar Mill Effluent Polluted Soil Using Earthworm and its Responses on Greengram (Vigna radiata L.)

Reclamation is an emerging technology that uses to clean up pollutants (metals and organics) from the contaminated soil. In this field of reclamation the utilization of earthworm is a new approach, to remove the metals from the polluted soil. The present work has been carried out for the reclamation of sugar mill effluent contaminated soil with earthworm. The physico-chemical analysis of sugar mill effluent and the polluted soils revealed that they are toxic in nature because they contain higher amount of micronutrients and macronutrients, organic and inorganic chemicals and heavy metals. The presence of pollutants in the soil mainly affected the plant metabolism which leads to growth and yield reduction. In order to enrich the soil quality, earthworm was cultured upto 60 days in polluted soil.  After that, the various soil properties were analysed and good percentage of pollutant reduction was observed. Germination studies were conducted in bioreclamated soil and best germination was noticed under bioreclamated soil when compare with polluted soil. ÂÂ

Biodiversity of Medicinal Plants in Thudaripettai Village, Nagapattinam District, Tamil Nadu, India

The medicinal plants have received more attention among researchers to treat various diseases and disorders. This study was aimed to record the various medicinal plants present in Thudaripettai Village situated in Tharangambadi Taluk, Nagapattinam district of Tamil Nadu. A total of 60 plant species belonging to 35 families were reported with their medicinal values. These results will provide information about medicinal plants and methods of utilization of these plants to cure various diseases of mankind. Survey of the information of medicinal plants used by the villagers were collected and arranged alphabetically followed by common name, vernacular name, family name, parts of use, methods of uses, medicinal uses and their habit. The information is very much useful for further research which will lead to the discovery of new bioactive compounds from the above medicinal plants

EFFECT OF CHROMIUM ON GROWTH AND YIELD OF Vigna mungo (L.)

This study was conducted to find out the effect of different concentrations (control 5, 10, 25, 50, 100 and 200 mg/l) of chromium on growth, yield of black gram (Vigna mungo L.). Pot culture experiments were carried out with black gram seeds with different concentrations of chromium solution. The morphological growth parameters were recorded at 15, 30, 45 and 60 days old chromium treated plants. The yield was recorded at the time of harvest. The study revealed that, the increase in chromium reduce the growth and and yield in black gram plants

Physico-Chemical Properties of Sri Sanishwaran Temple Pond Water, Tirunallar

ABSTRACT Tirunallar Saniswaran Temple dedicated to Lord Darbaranyeswaran, a form of Lord Shiva. Temple management imposes restrictions over misuse of these holy ponds. The devotees use the holy water for washing their limbs before entering the temple. Sometimes they make a holy dip into the water; people believe that it can wash all their sins away. Thousands of devotees visit the temple. So, the present investigation deals with the physiochemical properties of Sri Saneeshwaran temple pond water. Analysis of water samples revealed that the physico chemical properties such as p H , Electrical conductivity, Total hardness (mg/l), Ca hardness (mg/l), Mg hardness (mg/l), BOD (mg/l), Total Dissolved solids (mg/l), Suspended solids (mg/l), Chlorides (mg/l), Sulphate (mg/l), Sodium (mg/l), Potassium (mg/l), Dissolved Oxygen (mg/l) and Oil & grease (mg/l)., is varied significantly. Similarly the bacterial load is higher in after mass bathing than in before mass bathing
