| Characterization of
Rhizobium strain isolated from the roots of Glycine max (Soybean) (Aprana Alia)
CLICK HERE TO ABSTRACT Glycine
max (Soybean) is a species of legume native to East Asia, widely grown for its
edible bean which has numerous uses. The plant is classed as an oilseed rather
than a pulse by the Food and Agricultural Organization. It is known for its dietary
protein source, and symbiotic nitrogen fixation by Rhizobium present in its root
nodules. The present study describes the characterization of a Rhizobium strain
isolated from root nodules of Soybean. The Rhizobium isolates were rod shaped,
gram negative, acid and mucous producing. They were found to be pH sensitive,
with optimum values of 7.0°C. The bacteria was sensitive to the antibiotics
streptomycin. | |

| Comparative phytochemical
evaluation and antimicrobial properties of Pleurotus ostreatus (Manisha Bhardwaj,
Aprana Alia) CLICK HERE TO ABSTRACT This
study scientifically examined the photochemistry, antioxidant and antimicrobial
potencies of two organic extracts of Pleurotus ostreatus. Generally, both extracts
were effective against 89.8% of the isolates tested with Bacillus subtilis and
Escherichia coli exhibiting highest gram ± ve and gram -ve susceptibilities
by disc diffusion method, respectively. However, petroleum ether extract (PE)
exhibited greater anti-gram negative bacterial activity than the acetone extract
(AE) and further produced growth inhibition of these isolates in broth. Compared
to PE, the acetone extract elicited higher total phenolic content and in vitro
antioxidant capacity. Phytochemical analyses of the extracts revealed low to moderate
levels of terpenoids, tannins, and carbohydrates, while alkaloids were not detected.
The results indicate that P. ostreatus possesses antimicrobial. |

| Observations on the
Physico-Chemical Status In Motia Lake of the Bhopal (Mahima Dixit , Aparna Alia)
CLICK HERE TO ABSTRACT The
physio-chemical characteristics of Motia lake were monitored to determine the
water quality of the lake. Samples were collected on monthly intervals from the
lake. Physico-chemical parameters: temperature, pH, dissolved oxygen, alkalinity,
water transparency and nutrients were measured simultaneously. Present investigation
shows that status of the Motia Lake is eutrophic in nature. |

| Allelopathic effects
of Datura stramonium on seed germination and seedling vigour of Triticum aestivum
(variety GW 273). (Waseem Ahmad, Aparna Alia, Fatima Khan) CLICK HERE TO ABSTRACT
Wheat
is cultivated worldwide as a cash crop, it produces a good yield per unit area,
grows well in a temperate climate even with a moderately short growing season.
Majority of India's population eat food stuffs made from wheat, moreover our country
is the second largest wheat producer in the world. Datura stramonium is a naturally
fast growing weed containing tropane alkaloids (atropine, hyosyamine, and scopolamine)
and its presence has been sighted along the boundaries and hedges of the cultivating
fields of wheat. The present study focuses on exploring the allelopathic interactions
of Datura stramonuim on Triticum aestivum (variety GW273) seed germination and
seedling vigour. Aerial parts of the plant Datura stramonium were dried in the
oven at 80 degrees for 24 hours then crushed, mixed with distilled water and allowed
to stand for 72 hours in water bath at 25 (±2) degrees followed by filtration
using whatman's filter paper no.1.Four dilutions of different ratios were prepared
for the ongoing study. The extracts pose significant and varying allelopathic
effects on seed germination and seedling vigour of wheat. |

| Allelopathic effect
of Calotropis gigantea on seed germination and seedling vigour of Triticum aestivum
variety GW- 273. (Muzafar Akbar, Aprana Alia, Fatima Khan) CLICK HERE TO ABSTRACT
Calotropis
gigantea weed belongs to Asclepiadaceae family,is a shrub growing on the wasteland
and along the boundaries of wheat fields .It is world widely distributed but mostly
abundant in tropical and sub-tropical countries .It contains the (alkaloids,falvanoids,glycosides
,uscharins) the present study is to evolving the allelopathic interaction of Calotropis
gigantea on wheat (GW- 273) seed germination and seedling vigor. The wheat (GW-273)
variety is obtained from wheat research station Gujarat agricultural university
vijapur and is mainly cultivated in central zone (M.P). The whole aerial plant
part of calotropis gigantea were collected ,washed ,dried ,crushed and diluted,
different concentration of extraction were prepared ,the extraction effected on
the seed germination and seedling vigour of the wheat. |

| Bhopal Gas Episode
- A Case Study (Seema Tehseen , Sudhanshu Dhar Dwivedi) CLICK HERE TO ABSTRACT
Industrialization
has agreat impact on our lives. Philosophers have been warning us about the danger
of industrialization .We realize the price paid for progress only when a nightmarish
incident like Bhopal Gas Tragedy involving loss of numerous lives and many after
effects occurs .In the present paper we will discuss the incident, its impact
on the health of the victims even today when two and a half decade is over. |
