Abstract: Tropospheric ozone (O3)
is predicted to increase drastically in the coming years especially in south-
east Asia, due to climate conditions favourable for O3 formation.
Being a secondary pollutant, the concentration of O3 in the
troposphere mainly depends upon its different precursor molecules emitted
from various sources. O3 had been present in the troposphere since
ancient times in traces, however, in the last decade, its concentration has
widely increased which is mainly attributed to anthropogenic emissions of O3
precursors. The present review deals with the formation of O3 from
different precursor molecules, its trend in the troposphere in the recent
times and impact of increasing O3 concentration on plant yield.
Increasing O3 levels are of greater concern as its concentration
is higher even in the urban fringes and rural areas, which are the centres of agricultural production. Key words: Troposphere,
Ozone, Formation, Anthropogenic, Precursors, Agricultural production |

Abstract: Water is the key to a person’s survival because
without water survival is simply not an option.Due
to mosquito breeding the water gets contaminated. Mosquitoes are the most
single group of insects in terms of public health significance. Mosquitoes
are important vectors of several tropical diseases, including malaria, filariasis, and numerous viral diseases, such as dengue,
Japanese encephalitis and yellow fever. Anopheles stephensi
is the main urban vector of malaria in the Indo- Pakistan sub- continent and
Middle - East. Malaria is transmitted by the female Anopheline
mosquito. In Key words: Anopheles

Abstract: Experiment was designed to
investigate the effect of animal food utilization and energy budget of fresh
water fingerlings Catla catla and Cirrhinus
mrigala. Experiment was conducted to know the
influence of animal diet viz., earthworms, frog thigh muscle, goat liver, egg
white on C.catla and C.mrigala.Among the different animal diet
earthworm recorded significantly highest growth rate whereas goat liver, frog
thigh muscle, egg white diet were showed least influence on growth rate.Further, the study also revealed that animal diet
earthworm approached to be more effective in increasing the growth of both fishes.The maximum growth rate was seen in C.catla than C.mrigala
in all the animal diet. These results enable us to find out which one is

Abstract:Multivarious angles of
studies have been undertaken in the present investigation on the herbs cum
weeds-Tephrosia purpurea
and Tribulus terrestris.
These were made into vermicompost using the earthworm
Eudrilus eugeniae. A
comparative study was made on the effect of vermicompost
with Tephrosia purpurea
and Tribulus terrestris
on the vegetable crops (Tomato and Brinjal). It was
found that the vegetative growth of the vegetable crop was higher in the TtV applied tomato and brinjal
plants compared to the TpV applied tomato and brinjal plants. Also in comparison of vegetative growth
of control media (tomato and brinjal plants) with
the above said plants were lowest. The TpV applied
tomato and brinjal plants have shown earlier
flowering and high yielding compared to the TtV
applied tomato and brinjal plants. Also in
comparison of earlier flowering and yielding of control media tomato and brinjal plants with the above said plants were lowest.
The impact of weeds on the biomass of the earthworm was tested and was found
that the biomass was higher in the Tephrosia
purpurea diet than Tribulus
terrestris diet. Key words:Tt V-Tribulus terrestris Vermicompost, Tp V- Tephrosia purpurea Vermicompost |

Res. Environ. Life Sci., 4(2) 81 -86 (2011) Effect of growth regulators (BA and IAA) on metabolites and
enzymes at flowering stage in cucumber G. Tewari*,Brijendra P. Singh and Y. K. Sharma Department of Botany, *e-mail:

Abstract: The
changes in the morphological parameters pertaining to flowering in cucumber,
under the influence of combination of growth regulators (IAA and BA) are
studied. The days to anthesis of male flowers
decreased gradually over control when increasing concentration of only BA was
applied at seed germination stage. This decline in days to anthesis of male flowers was even more when BA was
applied at both seed germination stage as well as at the time of flowering.
However, the application of IAA at flowering stage (and BA applied at seed
germination stage) led to an increase in this parameter over control while
decline in the days to anthesis of female flowers.
The application of BA increased, while IAA reduced, the total no of male
flowers formation over control. The pollen sterility, though, was increased
as compared to control, in all the treatments. The treatment of BA at seed
germination stage led to a gradual decrease in the sucrose content during
pre-flowering stage in a concentration dependent fashion. The application of
BA or IAA at the time of flowering further reduced sucrose content. However,
IAA showed a greater effect on the reduction of sucrose content than BA.
Occurrence of flowering, like sucrose, caused a decrease in the starch
content in all the plants over the respective values at pre-flowering stage
too. Protein content showed a trend opposite to that of sucrose and starch.
At pre-flowering stage, protein content gradually increased with the
increasing concentration of BA given at seed germination stage. Application
of BA at the seed germination stage reduced sucrose synthase
activity in a concentration dependent manner. Application of BA or IAA at
flowering time further lowered the activity of the enzyme, with IAA causing a
greater reduction than BA. The activity of acid invertase,
showed a trend just opposite to that of sucrose synthase.
The activity of IAA oxidase consistently increased
as compared to control when increasing concentration of BA was applied at the
seed germination stage. Application of IAA at flowering time, however,
lowered the activity of IAA oxidase while the
application of BA increased the activity of PPO. Thus, significantly higher
activity of PPO was recorded in all the three cases when DW, 50 µM BA and 100
mgL-1 IAA was given at the time of
flowering. The application of BA and IAA also increased the activity of
peroxidase. Key words: Pre-flowering,
IAA, BA, Growth regulators, Metabolites, Enzymes |

Abstract: Lower concentration (10 and 25%) of
treated sugar factory effluent slightly reduced the seed germination but
seedling growth was enhanced while untreated effluent reduced in all
morphological parameters even at lower concentration. The chlorophyll
contents, amylase activity, sugar and protein content were also increased
while catalase and peroxidase activity decreased at lower concentration of
treated effluent. But the untreated effluent of same composition inhibited
seed germination and seedling growth, because of the higher organic content,
high BOD, COD and rich nutrients, beyond the limits of tolerance. The
chlorophyll contents were decreased while amylase activity was highly
increased. The 100% untreated effluent was found toxic due to the higher
concentration availability of potassium, calcium, magnesium, nitrogen, zinc,
iron, etc. and higher grease and oil contents and it completely inhibited
seed germination. Key words: Sugar
factory treated - untreated effluent, BOD, COD, and Seed germination. |

Abstract: Use
of neem oil in controlled way will be beneficial
for Spinacia oleracea
plant, as it was found to be non- toxic at least at lower doses. On the other
hand use of Cypermethrin as compared to neemoil was generally found to be quite injurious for
plant health thus may not be found to be as eco-friendly as bio-pesticide. In
spinach, increase in Chlorophyll ‘a’, was observed at 0.2% concentration of neem oil, which decreased on increasing the concentration
further. Similar trend was observed on application of cypermethrin
but it was found to be more severe than neem oil. A
significant decrease in Chlorophyll ‘b’, Total chlorophyll was observed on
application of neem oil and cypermethrin.
Same trend was observed in Carotenoid concentration. The catalase activity
was found to be increased at all the concentrations of neem
oil but cypermethrin, increased catalase activity
at 0.2% and 0.4% concentrations. Peroxidase activity increased at initial
dose (0.2% and0.4%) and decrease was observed at higher concentration of the neem oil and cypermethrin. On
application of both pesticides sugar content was decreased on increasing the
concentration except Sugar content was increased at initial concentration
(0.2%) of neem oil. Key words: Biopesticide (neem oil), Chemical pesticide (cypermethrin),
Chlorophyll, Catalase, Carbohydrate. |

Abstract: Bioactive components and probiotics in foods and the positive interactions
generated by these components are showing promise in reducing risk of certain
diseases such as infectious diarrhea and enhancing overall health and
well-being. The study was aimed to develop and outline the role of probiotic buttermilk as a general health protective,
preventive and cost effective functional food. Through the study an effort
has been made to find out the efficacy of buttermilk which is commonly
approachable and low cost milk product with ‘probiotics’
acting as neutraceutical in combating intestinal
diseases. The study involved the development of probiotic
buttermilk (lactobacillus and bifidobacteria
preparation), its organoleptic evaluation and
clinical trial on 31 diarrheal patients selected purposively. The data was
tested at 5% level of significance by applying statistical t-test. Data
recorded showed that 100% patients in experimental group recovered with no
reoccurrence of diarrhea after the administration of probiotic
buttermilk where as only 73.33% recovered with the use of medicine in the
control group with 26.66% having reoccurrence of diarrhea after 10 days of medication.Clinical and statistical results of the
interventions draw firm conclusions about the efficacy of probiotics
in lowering and/or improving the diarrheal symptoms and its reoccurrence. Key words: Bioactive components,Infectious diarrhea, Probiotic
buttermilk, Functional food, Organoleptic
evaluation, Clinical trial. |
