This paper describes the fruiting phenology and avian frugivory of Streblus asper (Moraceae) in a mixed dry deciduous forest, Anaikatty hills, Western Ghats. Fruiting occurred during April-June. Nine species of birds were found to feed on the ripe fruits of this species. Bulbuls (3 species) belonging to Pycnonotidae, followed by two species of Myna (Sturnidae) made majority of the feeding visits and appear to be the major seed dispersers of this species.
This paper describes the fruiting phenology of 110 individuals of woody species belonging to 22 taxa (21 species, 1 variety) belonging to 15 families including 2 species of figs in a scrub forest, Thiruporur, Eastern Ghats. Fruiting peak was observed during July 2009 with 11 species in fruiting, a dip was observed during March 2009 where only 2 species were in fruiting. Season wise fruiting peak was observed during South-west and North-east Monsoon while the dip was during summer.
The plant Justicia simplex D.Don is traditional herb, people used it in different diseases, they treat fever and burning of the body, strengthen the lungs, the teeth and stop vomiting. The plant exhibited more promising bacterial activity against various microorganisms. Hence, in the present study this plant is also tested against the dental pathogens. The plant was extracted from four different solvents was tested for the presence of phytochemicals in it. After analyzing, its antimicrobial activity is tested against fungi and bacteria. Then a dental carrier Streptococcus aureus, Klebsiella pneumonia, Escherichia coli and Pseudomonas aeruginosa which was collected from the K.S.R. Institute for Dental Science and Research. The isolates were used to check the activity against Justicia simplex D.Don. Based on the positive result obtained against various analyses, it is formulated successfully into a tooth paste. The present study on Phytochemical screening of Justicia simplex D.Don a valuable medicinal plant extract against Dental pathogens enables the use of this plant for the formulation of tooth powder against dental pathogens. The result is more effective against dental pathogens by herbal tooth powder.
Biofertilizers are the special formulation of specific beneficial microorganisms that promote the growth of plant crops by converting the unavailable form of nutrients into available form. Here, the effect of heavy metal stress on antioxidant enzymes were studied in Clitoria ternatea L. leaves. Clitoria ternatea L. plant was grown for 30 days and the heavy metal mercuric chloride was sprayed after 10 days from the date of planting. Effect of mercuric chloride was observed in treated plants. The selected plant Clitoria ternatea L. was grown under mercuric chloride treatment in a specified concentration 1 μg/10 ml. The control plant maintained without the treatment of mercuric chloride. Antioxidant effect of mercuric chloride was measured under controlled and treated conditions. The selected plant Clitoria ternatea L. was grown under mercuric chloride in treatment. Further it increases H2O2 content and the antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were observed in mercuric chloride treated plants when compared with control. Here mercuric chloride was accumulated more in matured leaves. The results are discussed with the literature.
